CyberMesh: giving my Meshtastic node a real dashboard
For a while the only way to talk to my Meshtastic node (a T-Beam I
call WY6Y MC1) was the official phone app over Bluetooth, or
nothing. Classic ESP32 T-Beams don't ship a web dashboard of their
own: the hardware only exposes a raw serial/TCP protocol, no HTTP
server. If I wanted browser-based control from anywhere on the home
network, something had to build the missing frontend.
CyberMesh is that frontend. A live map and node list with RF vs
MQTT source tagging. Messaging, broadcast and direct, with delivery
acknowledgment that now distinguishes an RF ack from an MQTT one.
Every config section and every channel exposed as editable JSON
instead of a dozen hand-built forms, so the app covers the whole
device without me reimplementing each settings page one at a time.
Async traceroute with saved "proven path" routes. And a channel
health chart tracking the node's own airtime congestion against ack
success rate, because "my message failed" and "the shared frequency
is busy right now" turned out to be the same graph.
The build log isn't all clean wins. One evening a channel edit
meant for a secondary channel landed on channel 0 instead: the
node's primary key, silently swapped for the wrong one. A protobuf
field got cleared and never reset before the write went out, so the
radio decided which slot to overwrite based on a value my own code
had just zeroed. Caught it by noticing the readback looked wrong,
confirmed it against the real device over serial rather than
trusting a cached view, and got the primary channel back before it
mattered to anyone else on the mesh. That's most of what building a
tool like this actually is. Not the demo. The recovery.

node:

ATNO: counting countries, remembering the bed-bound FT8 winter
I finally built the DXCC board I keep wishing existed when I open the
log: ATNO. Not a cloud app. Not a spreadsheet with color rules
I forget how to use. A self-hosted hunt dashboard that reads ADIF,
marks what is actually confirmed (LoTW, eQSL, or a card in
the hand), and puts the rest on a world map with distance, bearing,
and a great-circle beam from the home grid. Watchlist pins for the
rare ones. Search for what is still needed. A little progress ring
that does not lie about how far 246 is from the full current list.
The multi-call detail mattered more than the pretty map. My
history is split across two full logbooks: the old call
KI5WKB and the current WY6Y. Full ADIF exports are
whole stations, not deltas. So the board keeps one file per
callsign. Re-upload replaces that slot. Confirmed DXCC is the
union of both. No double-counting if I dump the same log
twice. That sounds boring until you have lived the other way.
Looking at that union number always sends me back to the winter of
2023. COVID had me stuck in bed for a stretch that felt longer than
the calendar. The shack was still upstairs. The radio was still
alive. I was not. What saved the hobby that season was a dumb,
wonderful discovery: you can run FT8 over VNC. Not glamorous.
Not a Field Day story. Just a laptop on the covers, a remote
desktop into the shack PC, and the waterfall ticking while the
rest of me tried to stay horizontal.
A large chunk of my DXCC pile-up came from that bed. CQ, reply,
73, next. Country after country while the body recovered on its
own schedule. Some people remember their first DX as a contest
pileup or a sunrise grayline miracle. Mine is mixed with fever
dreams and the soft click of a trackpad. I am not romanticizing
being sick. I am grateful the airwaves still let you show up when
you cannot climb the stairs.
ATNO is partly for the next rare one on the watchlist. It is also
for that older call and that quieter winter: proof that the
contacts still count, still light up on the map, still add up to
something you can see without opening five programs. If you want
to run the same board at home, the code is public:
github.com/WY6Y/ATNO.
Bring your ADIFs. Keep the old call. The bed-bound QSOs earned
their place in the union.

CyberRig: finally driving my own radio
For years the FTDX10 lived behind Win4Yaesu. Fine software. Not
mine. Not something I could fix at 11 pm when a meter felt
laggy, or open on a phone without wrestling a remote desktop.
CyberRig is the replacement: a browser-based CAT control app that
talks straight to the radio, runs on the shack PC, and still lets
me operate from elsewhere on the home network.
It's past "hello world." Bi-directional sync so the front panel and
the UI stay honest with each other. Internal ATU and remote tune for
the external box. Parametric EQ, macros, memory channels, a PWA that
actually behaves on iOS. There's a real RTL-SDR panadapter now too:
wideband, not the sad little audio-FFT slice, sharing the shack
dongle with the WSPR decoder and pausing that work when you open the
waterfall. Getting that handoff right took more live debugging than
I'd like to admit.
First real QSO through the app: 59 with W9IMS on 20m. That
one landed. Remote SSB is wired and working, but I'm not clearing it
for unattended key-up yet. Dummy load polish first, antenna later.
There's a native desktop window now for the shack monitor (same
server, no browser chrome), and VarAC already talks to it over
hamlib without inventing virtual COM ports.
Still WIP. Still replacing a mature Windows tool one feature at a
time. But when you're mid-net and the rig just responds the way you
built it to, that's the whole point.

Mesh swap: Google WiFi out, Deco in, everything broke quietly
Swapped the old Google WiFi gen 1 mesh for TP-Link Deco AX1500
units. New gear, new default LAN, new subnet. I chose not to force
the mesh back onto the old addressing scheme. Just re-point
everything and set reservations for whatever DHCP handed out.
That was the right long-term call. It was also a full-day
scavenger hunt.
Half the fleet still had the old Pi IP baked into firmware and
service defaults. WeatherThief, CyberHUD, the smoker Pi. Serial
logs that said MQTT was fine until you realized nothing was
actually publishing. Tailscale subnet routes do not magically
follow a CIDR change either. You re-advertise, then you go
approve the new route in the admin console by hand.
The real gotcha was quieter. The Pi's firewall still allowed MQTT
and a few other ports only from the dead subnet. From the ESP's
point of view that looks exactly like a wrong broker address.
Fixing device configs alone would never have been enough. If you
ever change home subnets: grep the firewall for the old CIDR, not
just the apps.
WiFi-only boxes (solar shed, bedroom UPS monitor) needed their own
watchdogs after the dust settled. Power-cycle recovered them once;
software now tries not to need that twice. The mesh itself is fine.
The lesson is not "Deco is bad." The lesson is that a quiet
house full of hardcoded LAN IPs will punish you the first time the
network map moves.

Adventures of WY6Y-14
Mid-July we boarded MSC Seascape out of Galveston: Costa
Maya, Roatán, Cozumel, then back home. Family trip. Pool. Ports.
The usual ship chaos. I also decided the radio callsign was coming
along for the ride.
On the air I was WY6Y-14: phone APRS from the deck and the
cabin, pinging the network the whole week so anyone who cared could
watch a little cyan blip crawl across the Gulf. Back home, a small
logger on the Pi subscribed to the worldwide feed for that one
callsign (not the local digi, which only hears Oklahoma) and
wrote every fix to disk. By the end of the full sea days that was
something like twelve hundred beacons and roughly
nine hundred track-miles of real positions. Open water
mostly sat in the teens of mph, with one ridiculous spike that
was almost certainly a GPS hallucination, not the ship doing
thirty-eight knots past a reef.
Half the fun was the dual life. One thread was ports and weather
and kids and whether the storm track was going to get interesting.
The other was the house. WSPR falling over for a stretch, the
shack PC deciding Windows Update was more important than staying
reachable, the usual fleet drama you only notice when you're
three hundred miles offshore and still get a Telegram ping about
it. The trip didn't stop the lab from being the lab. It just made
the alerts feel a little more cinematic.
When we got home I wanted more than a screenshot. The full track
got turned into a proper voyage log: day-by-day notes, a few
stats that aren't made up, and a map of the real APRS fixes from
when the logger was running (with the pre-beacon Galveston leg
honestly marked as estimated, not telemetry cosplay). If you want
the live callsign trail the old-fashioned way, it's still out
there on
aprs.fi as WY6Y-14.
Not a DXpedition. Not a contest. Just a ham who couldn't leave
the hobby at the pier, and a week of positions that turned into
a memory I can actually open later, instead of a phone photo I
never find again.

WeatherThief and CyberPWS: stealing the sky on 433
I got tired of paying a cloud service to tell me what was happening
in my own backyard. The outdoor box is an AcuRite 5-in-1 on the
property. WeatherThief is the little thief next to it: an
ESP32 with a CC1101, sitting on 433 MHz, running OpenMQTTGateway
and rtl_433, decoding the station straight off the air and shoving
packets onto MQTT. No vendor bridge. No monthly plan. Just RF.
That path was not free. Wrong GPIO on the CC1101 and the board
won't even boot. Flash while the radio is attached and you need the
weird esptool flags or it lies to you. And the first time the ESP
rebooted clean, it happily locked onto a neighbor's indoor sensor
stuck at a perfect 68 °F and corrupted the outdoor reading until
I filtered hard on sensor ID 563. Expensive lessons. Kept
every one of them.
CyberPWS is the dashboard that makes the theft worth it.
Live wind, feels-like, humidity, rain, NWS alerts, a local radar
loop, daily highs and lows, a health strip so I can see whether the
RF path is actually alive. When 433 gets ugly (fireworks night is a
classic), a watchdog tries to reinit the radio and, if that fails,
reboots the whole WeatherThief box and pings my phone. The same
feed lights the shack touchscreen and, later, the APRS weather
beacon. One outdoor sensor. Several things that depend on it not
lying.
This is also the look the rest of the fleet stole from. Deep black,
cyan hairlines, monospace HUD energy. When I finally built a public
site, I did not invent a new aesthetic. I started from the weather
app, because that was the one I kept opening just to stare at.
Dashboard code is public:

CyberHUD: one glance, five tabs, no laptop
CyberHUD is a cheap 3.5" ESP32 touchscreen I stuck in the
shack so I would stop opening five browser tabs just to know if the
house was still honest. Weather, solar, the smoker, the YSF
hotspot, and the APRS digi. Tap a tab. That's the whole product
pitch.
Under the glass it's MQTT most of the way: the same weather and
solar feeds the rest of the fleet already publishes, plus a
dedicated APRS snapshot so the digi tab only shows RF-heard
traffic, not the whole internet. The pit tab is the odd one out.
It just polls the smoker Pi over HTTP, because that box is often
cold and offline and I would rather see UNREACHABLE than fake
data. Long-press on the APRS side can toggle the weather beacon's
RF path when EchoLink needs the radio quiet. Small station
manners, built into the glass.
Firmware taught me the hard lessons. Early builds starved the MQTT
keepalive while hunting a hotspot that was sitting in the truck
three states away, so the screen went "Uplink Idle" every minute
like a bad joke. Fixed that. Later it kept jumping tabs by itself
because the touch controller was free-running on SPI noise until I
finally gated reads on the real interrupt pin. Flash from the Pi
over USB, bump the version in a few places, keep a binary backup
before every upload. Boring process. Saves the night.
No public repo for this one yet. The point of the panel was never
open source flex. It was having the station stare back at me from
across the desk without unlocking a phone.

CyberAPRS: digi, map, and a weather callsign of my own
APRS in the shack used to mean "Direwolf is running somewhere and I
hope the audio levels are still good." CyberAPRS is what happens when
you refuse to leave it at that: a full digipeater and IGate on
WY6Y-7, plus a dashboard I actually want to look at.
RF path is the shack TH-9800 into a Tram up on the pergola,
roughly thirty feet of real air, not an attic compromise. Packets
come in over KISS; the map shows who's local, who bounced through
me, vehicles with tracks, weather stations, and a "heard direct"
ring when someone hits the digi with no hops. Messaging works both
ways (RF and APRS-IS) so a "howdy" to a mobile isn't a coin flip
between paths.
The weather half is the part that still makes me grin.
WY6Y-13 beacons the outdoor conditions off the same AcuRite
the house weather project already decodes, and that feed is in CWOP
now too. There's a mode switch for when EchoLink needs the radio and
the weather beacon needs to stay quiet on RF for a bit. Little
details like that are what separate a demo from a station.
Side quest while I was at sea: phone-beaconed as WY6Y-14 the
whole cruise and logged the track back home. Twelve hundred-odd
fixes later, the voyage path is a keepsake, not a screenshot I
forgot to take. That's the theme with this whole project. If the
radio is doing something interesting, I want a place to see it,
not a console window buried on another desktop.

Two hotspots, two jobs (and they are not the same Pi)
People hear "digital hotspot" and assume one box. I run two, on
purpose, and mixing them up is how you waste an afternoon.
Pi-Star is the part-time DMR/YSF machine for when I want the
full Pi-Star image and dashboard. Callsign WY6Y, sits idle between
sessions, comes online when I'm actually using digital voice that
way. Fleet access, web admin, the whole ritual. It is not the truck
box.
CyberFusion is a Pi Zero 2W running MMDVMHost and YSFGateway,
home or truck, with its own little dashboard. YSF is the day job.
It also grew an APRS mobile tab for phone GPS beacons as
WY6Y-9 over APRS-IS, separate from the shack digi. When the
truck is away, that node going quiet is normal, not a crisis.
Same hobby, different hardware, different software images, different
jobs. If a fleet check says "CyberFusion offline" and you go
rebooting Pi-Star, you are solving a problem that does not exist.

NeonMeatProbe: brisket deserves telemetry too
NeonMeatProbe is a Pi Zero 2W that only wakes up when there
is meat on the line. MAX6675 thermocouple, cook history, stall and
flameout detection, phone alerts, a PWA so I can watch chamber
temp from the couch without opening the lid every ten minutes.
Production name on the box is neonmeat. The long-term name is
CyberPitOS. Same family.
Offline on the network map most days is expected. The smoker Pi is
not a 24/7 server. When I'm not cooking, power is off. When I am
cooking, the shack touchscreen's pit tab should show real numbers,
not a polite lie. UNREACHABLE when cold is a feature.
There is a second, newer dual-sensor path on the same machine that
is still WIP. NTC probes and a proper ADC. Last serious bring-up
got spicy with WiFi resets. Production stays on the thermocouple
stack that already smoked good brisket. Fancy sensors can wait until
they stop panicking the board.

CyberSDR: the radio that listens while I sleep
CyberSDR is a WSPR decoder and propagation dashboard. An
RTL-SDR Blog V4 on the shack PC watches HF through a long end-fed
in the yard. The app on the main Pi runs the schedule, decodes,
maps spots, and uploads to wsprnet.org. Smart band rotation across
40m through 10m (80m got cut; the slots were not earning their
keep), greyline on the map, per-band gain tuning so the dongle is
not deaf on one band and deafening on another.
The dongle is shared gear. SDR++ uses it. CyberRig's panadapter
borrows it. The WSPR engine pauses and resumes so nobody owns the
USB forever. That handoff is more interesting than the pretty
map, and it has bitten me when a capture was still mid-flight.
During the cruise it went silent for about eight days while the
container still looked "up." Wedged USB/rtl_tcp, zero spots in the
database, monitoring that only checked the box was running. Power
cycle on the dongle path brought the ocean of spots back. Lesson:
a green container is not a green decoder.

CyberPVS: the solar shed without the Victron app
Out behind the house is a solar shed with real Victron gear in it.
The stock app is fine if you want to stand next to the equipment.
I wanted the numbers on the same network as everything else, so I
built CyberPVS.
A Pi Zero lives in the shed and speaks Bluetooth Low Energy to the
Victron devices, then publishes telemetry over MQTT back to the
main Pi. The dashboard on that end is the usual cyberpunk PWA:
live charge state, solar yield, battery and load at a glance,
installable on a phone so you can check the array without opening
a laptop. When the shed goes quiet, demo mode kicks in so the UI
does not look dead forever. When the data comes back, it flips to
live without drama.
I tried load control over the same MQTT path for about one evening.
Relay commands out to the Zero, BLE poke at the Victron side. It
worked, then I turned it back off. Flipping loads from the couch
sounded cool until I remembered what a bad UI click does to a shed
full of batteries. Telemetry stays. Remote load switching can wait
until I trust myself more.
The shed is WiFi-only, which means mesh upgrades and overnight
dropouts hit it harder than the wired gear. That is a feature of
putting a computer next to the panels, not a bug in the solar.
Watchdog on the Zero, reserved DHCP, MQTT as the narrow pipe home.
Same pattern as the rest of the fleet: keep the smarts local, ship
only the data that matters.

Mag loop: 10 feet of copper and a lot of Q
I built a high-Q magnetic loop in the garage from 10 feet of
M-class copper tubing, cut into straight segments and joined
with 45° elbows into an octagon about three feet across. Gap at
the top, Johnson 154-9 air variable capacitor on short fat
straps, small inductive coupling loop with an SO-239 inside the
main loop. Vertical on a non-conductive stand. No magic, just
copper and patience.
On the air it covers 40m through 10m. From Oklahoma City on
the Xiegu G90 at 20 watts I worked Vancouver, Washington, almost
two thousand miles, S9+10. Audio was excellent. Noise rejection is
the part people undersell until they hear it. Compact enough that
HOA and small-yard ops make sense.
It will not be my daily driver across the band plan. High Q means
you retune when you move, and a NanoVNA session every hop gets old.
Perfect when you park on one frequency for a net or an activation.
An auto-tuner for this loop is still on the bench list. Until then,
the loop stays a sharp tool, not a broadband hammer.

WY6Y-PI Switch: remote antennas without climbing
I operate HF remotely most of the time. VNC into the shack PC,
digi modes, Winlink, the occasional SSB. Two permanent antennas
(the 80m all-band doublet and the Emcomm III-B) and no interest in
walking upstairs every time I need the other one. Commercial
remote switches that fit how I work were thin on the ground, so I
built the WY6Y-PI Switch on a Raspberry Pi Zero 2W.
Cyberpunk web UI, relays, three ports (Doublet, Emcomm, Aux).
Failsafe grounds everything if the Pi loses power. Storm Mode
grounds on purpose from the browser when weather gets ugly
(still not a substitute for real disconnects). Three hardware
revs to get the RF path right: unshielded wire was a disaster on
SWR, RG-400 was too stiff for the compact board, RG-316 with SMAs
finally behaved. About 1.73:1 on 10m into the Doublet when
I measured it. Good enough for a homebrew box that lives bonded
to the shack ground system.
I was a Pi and Linux noob when this started. Bricked a Zero
learning to solder. Taught myself the Python and the web front
end because the alternative was staying stuck on one antenna.
The switch has been quieter in the amp era (the FL2100B changed
how I park the station), but the box and the code are still
there when remote HF needs a different radiator again.

Winter Field Day 2025: G90, Winlink, and whatever was on the shelf
Winter Field Day 2025 was a simulated emergency run for me, not a
hotel contest suite. Xiegu G90 on the air, Winlink forms over
HF, and power only from homebrew LiFePO4 packs borrowed out of the
solar shed. Antenna was the CHA Emcomm III-B. If the grid is
pretend-dead, you use what you already own.
The station look was pure scavenger. Beelink mini-PC on an inverter
pulled out of old photo gear. Six-inch monitor I usually stick on a
Raspberry Pi. Mini Bluetooth keyboard and trackpad. DigiRig for
sound card, CAT, and PTT into the G90. Small screen made Winlink
annoying. That was the point. You find the bugs when your fingers
are too big for the UI and the "desk" is a table you just cleared.
Setup path that worked: Winlink VARA HF session, rig profile as
Icom 7200 USB Digital (the usual G90 cheat), DigiRig COM port at
19200, VARA pointed at the DigiRig sound device with PTT tested in
Windows sound settings. VARA itself still bothers me. Great modem.
Windows-only. I would rather run this whole stack on a Pi someday.
Until someone ships a real cross-platform alternative, Winlink HF
for me still means a little Windows box in the pile.
If you want to learn the program, the Tulsa ARES Winlink net is
Thursday nights. Send a Winlink check-in to AE5ME and jump in.

Attic antennas: they work, and they are not the endgame
My first antennas lived in the attic. HOA nerves. Not sure yet if
the hobby would stick. Not ready to string wire where the neighbors
could point. So the dual-band VHF/UHF stick and a 40 through 10
EFHW went upstairs under the roof, and I got on the air anyway.
Did they work? Yes. Local repeaters were fine on two meters and
70 centimeters. That attic EFHW helped me earn a DXCC. Good
enough to fall in love with HF. Not good enough to pretend the roof
is free air. Anything that works in an attic will almost always
work better outside if you can get it there. Roof material eats
signal. Wire couples to every pipe, duct, and mystery conductor in
the joists. Sometimes your RF finds the toaster before it finds
Europe.
Would I recommend attic antennas? Only if that is what you have.
If it is the only option, put something up and operate. You will
learn more in a month of real QSOs under a roof than in a year of
waiting for the perfect outdoor install. My attic wires were the
first step, not the last. Outdoor antennas came later, when the
hobby had already won.
(Fair warning: the audio on this one is rough. Shot before I got a
decent mic. The take is still the one I mean.)

G90 go box: ammo can, wood scraps, backyard portable
The Xiegu G90 is the QRP travel and backyard rig. I got tired of
hauling a naked radio and a rat's nest of cables every time I
wanted to operate outside with the dog. So I built a go box the
old-fashioned way: a 50-cal ammo can plus some woodworking,
using leopard wood scraps left over from another project.
Ham radio and the garage, same afternoon.
The radio lives in the can. Fan and vent keep it breathing. Audio
actually got better in the enclosure, which I did not fully expect.
Ventilation has not been a problem in real use. Power rides along
in a second ammo can with a LiFePO4 pack so the whole station is
grab-and-go: lid, whip or wire, battery box, on the air in the
backyard without a pilgrimage to the attic shack.
It is not a contest multi. It is the box I reach for when I want
HF outside in a hurry, or something travel-ready that does not look
like a science fair. SSB, CW practice, digi when the mood hits.
Same G90 that later put Vancouver in the log through the mag loop
at 20 watts. The can just makes the radio a habit instead of a
project every time.

UV-PRO: email over the air from a handheld
Packet is not dead. It just needed a radio that stopped pretending
a TNC was optional. The BTECH UV-PRO (same bones as the VERO
VR-N76 and Radioddity GA-5WB) has a Bluetooth KISS TNC built in. Pair
it with RadioMail on iOS, hit a Winlink packet RMS, and you
are sending real email over VHF without a laptop pile on the picnic
table.
My demo path was simple: attic J-pole, phone, radio. No external
sound card drama. That is the whole point. If more HTs ship with
honest packet TNCs, rural and campground Winlink stops being a
specialist sport. Strategically placed nodes and a handheld you
already own, and you stay in the loop when the cell tower is a rumor.
I still use the UV-PRO as a normal dual-band HT. The KISS path is
why it stays in the kit instead of the junk drawer.

UV-PRO first light: app, APRS, and kill the PTT beep
First real week with the BTECH UV-PRO. Battery life is
silly good. Programming through the BTECH phone app is painless
for a dual-band HT. Built-in APRS map and messaging in that app
means you can see the local packet neighborhood without a second
gadget. Sound reports on the stock duck were already solid. Feature
list is long enough that you will flip two switches the wrong way
on day one. I did.
People were hearing digital trash at the end of my overs. That was
PTT Release ID, on by default. Turn it off. I was also eating
constant APRS noise until I sorted digital mode properly.
Firmware update and channel load all go through the same app. The
part I keep using daily is the BS-22 Bluetooth mic/speaker:
radio parked on an external antenna across the room, good audio in
my hand, no leash.
KISS TNC already talked to RadioMail on iOS in this session even
if the Winlink RMS handshake still needed a later day (and a later
video) to stick. Setup video first, on-air email second. That order
matched how the radio actually entered the kit.

Backyard portable: solar shed, doublet, and 3.916 trivia
Backyard portable is half the fun of this hobby for me. Xiegu G90
in the ammo can, homebrew LiFePO4 packs, and a newly renovated
solar shed with two 100-watt panels keeping the batteries honest.
Low power, real antenna, outside with the radio instead of locked
in the attic.
The wire that day was the all-band doublet my elmer KX0U
steered me toward: works 80 through 10, 300-ohm window line into an
MFJ-994BRT remote tuner, Bias-T so the tuner eats from the
same battery pile over the coax. Daytime I hang out on 10 or 20.
Night I slide to 80 for the 3.916 Freewheelers Trivia net.
Quieter than 40, solid for short-to-medium range, and the regulars
turn into friends if you keep showing up.
QRP in the yard is also antenna honesty hour. You find out what
the wire actually does when you are not leaning on a hundred watts
and a quiet living-room chair. The can still makes the G90 audio
sound better than it has any right to. That part never gets old.

Slingshot, throw line, and a tour of the antenna farm
Getting wire into a tall tree does not require a tower crew. For
this one I used an arborist throw line and a Big Shot
slingshot to park a Chameleon Emcomm III-B end-fed up about
35 to 40 feet. Same antenna I still run as a shack radiator and
the one that went to Winter Field Day. Trees are free masts if you
are willing to look silly for five minutes in the yard.
End-feds earn their keep. Little feedline, multiband, one support
is enough. That day it was a half-V / flat-top mix. I have also run
it inverted-V, flat-top pure, and straight up a tall pine as a
vertical. For camping it is the "find a tree, get on the air"
antenna. Height helps: that deployment was solid for DX on 20
through 10 and NVIS-friendly on 80 and 40.
The video is also a short walk around the rest of the farm: Tram
dual-band on the pergola for VHF/UHF, Wolf River coil and whip in
the portable kit, the usual half-finished ideas every ham yard
collects. Incomplete tour on purpose. Antennas change. The
slingshot method stays.
