Ham Update 2024, 2024-May-01 Wed, "QRZ.com update"
Meshtastic Rak Module
(Meshtastic Rak Module)

I ran into Meshtastic and started playing with it. Not quite ham radio, but it is radio technology, affordable and easier to share with friends. So far I have only a single Rak Wireless device in my kitchen. Very compromised setup for 915Mhz, but surprisingly I pick up a number of nodes through repeaters on the Santa Cruz Mountains ridge. The plan is to setup a solar node above the roof line and get more direct coverage and range. I’m interested in emcomm aspects of Meshtastic and exploration of it as APRS replacement.

(Stock Picture of Wifi6 Usb3 Network Adaptor)

Needed a #USB3 #Wifi6 adapter for my backup server, as the old atheros 9k got flaky. Found this Mediatek based nic supported by mt7921u driver in #linux kernel 6.1 + firmware blob (firmware-misc-nonfree package on #debian ). My dhcpcd immediately got dhcp lease upon plugging (’n-play). The device came with high gain antennas and was only $25!! https://www.amazon.com/dp/B0CVVWNSH2?psc=1&ref=ppx_yo2ov_dt_b_product_details

#PSA : if you use a personal locator beacon ( #PLB ) and wish NOT to spend a small fortune on a replacement battery every five years, here is a source of quality replacement batteries: https://beaconbatteryreplacement.com/ beaconbatteryreplacement.com/

followup:

All it took is two screws to open the #plb and take out a shrink wrapped 3-cell battery. It is composed of three CR123 Lithium Manganese Dioxide non-rechargeable cells wired in series. Popped in the new battery and good for another 5 years!!

Innovative #EAB #autopilot (SuperEco) based on , 2024-Apr-20 Sat, "aerodynamic trim-tab actuation from Aircraft Automation. Conceptually, "
Super Eco Autopilot and Trim Tabs
(Super Eco Autopilot and Trim Tabs)

Innovative #EAB #autopilot (SuperEco) based on aerodynamic trim-tab actuation from Aircraft Automation. Conceptually, it is very elegant. Not sure about RC servo reliability when used continuously, but for <0.5AMU one could replace all three servos every few years. Watch installation and flight demonstration video: https://www.youtube.com/watch?v=3UJoCmkDJFk

followup:

@h4890 hi, I don’t know regs in your country, but in US there is part91 for private owners operators which does not restrict flight over water. Part135 (air carrier) does. Aircraft age - no maximum from safety pov. I have a 77 year old airplane. All airplanes receive annual inspection to ensure continued operation. As long as a given aircraft type has parts availability, then age is not a safety issue. There is increased maintenance cost compared to new aircraft but at MUCH lower acquisition.

With bad weather, I had time to solder a SH connector to the 6W solar panel. Then I formed aluminum L-channels for mounting the panel to my #meshtastic node. Very light weight, less than $20 including the panel and STRONG. The ABS pipe will break before this solar mount will.

Finally weather improved and I could fly places. Today I checked out the town of New Cuyama, CA and their resurfaced runway at #L88 . Post frontal weather provided for postcard views, turbulence, updrafts and downdrafts. Lots of gliders spotted :) When departing L88, I caught a thermal and between the O-200 and nature, I was climbing in a steep turn at 1000fpm to quickly reach altitude to hop into the next valley.

Installed my #meshtastic node 20ft above ground with a high gain 8dBi #antenna . Reliably hitting many nodes now and even got folks responding on ‘LongFast’ channel. I spent about $30 on parts for this. Used a 10ft 2" ABS pipe, U-mounts, scrap wood and a 3d printed adapter to stabilize the antenna against the pole. Next I’ll make some sheet aluminum angle pieces and mount the 6W panel to the rig - I have a week and a half until the fully charged battery drains :)

I used to fly FPV a lot and followed these pilots for years. The “out of the body experience” is amazing. I haven’t experienced it before or since #flying FPV. When you fly around yourself to “avoid that person” only to realize that it was you, while in #flowstate , is indescribable. Amazing & so familiar! https://www.youtube.com/watch?v=UoMWFrqOmQo&t=5240s

I started a long weekend today and went flying. Bumpy, thermals everywhere, cloud bases at 6k and the world is green again (bugs included). I took my #meshtastic Rak device and from 5k feet up I was “heard” 40 miles away in Fresno by a user who emailed me. My cabin is starting to look like a ham cave - antennas from left to right: #meshtastic , #ADSB -in, #APRS -out.

Q. how to find #bluetooth address of already paired #meshtastic device? I paired it with my android and works great with an app, but I don’t know the full bt mac-addr. BT scanning from my PC doesn’t show it, but shows other devices in pair mode. How to force meshtastic to go into pairing mode? OR how to lookup device’s BT address? OR are multiple clients paired to same meshtastic device supported? I know I can re-flash, which which should reset settings and allow me to pair again.

There is #meshtastic in the air :) Just setup my first node - a rak wireless unit. Uses only about 300mah per day including air sensor. Meshtastic is a 915mhz #lora based, very low power, messaging and beaconing system. Quite similar to #amateurradio #aprs . I upgraded the antenna to a 3dBi, but since LORA is line-of-sight and very low power, I get no range. The only nodes I picked up are those on the hills 10mi away. Next: solar panel, the board already has solar charge controller for 1s lipo.

Yesterday, during IFR evening, I completed ground BFR portion with a new-to-me instructor. I liked that he started by asking “what is your mission”? A: >50mi cross country in own aircraft; following which, he optimized our time to relevant topic areas. He stumped me with: “why idle power on the ground is NOT as much of a carb icing risk, as idle power in descent”? Q. what would you have said? (I tried a bunch of familiar to me explanations…)

#Cups #OpenPrinting project and printers themselves came a long way since Cups 1.x. Internet Printing Protocol #IPP uses a pdf/raster payload and supports config exchange - no more PCL/PS/custom printer languages. No more PPD files and no binary drivers from manufacturers \o/ Now if I could point cups-client to a IPP network printer directly (via client.conf) that would be perfect - faster than avahi and less overhead than having cups-service daemon on my network.

Recently updated my main linux box , 2024-Jan-14 Sun, "and couldn't rebuild one of my own system "

Recently updated my main linux box and couldn’t rebuild one of my own system management tools from 2002. The cause were old #autoconf and #automake artifacts. Spent 2h cleaning up and regenerating from .ac and .am files. Remembered how miserable #autoconf and #automake really are: shell based, slow and dropping a ton of persistent artifacts in my source tree. After finishing, I found #meson as a modern replacement, see: https://mesonbuild.com/Comparisons.html

As much as I disliked systemd initially, I hate working with hacky shell script based sys-v-init. Recently I needed a short daemon to monitor network connectivity of my backup server. I wrote a py program to do that and instead of making it a daemon with backgrounding, logging, writing sysv scripts for it etc, I wrote a 10 line systemd service definition. Anything it prints to stdout+stderr gets logged, it is auto-restarted, memory limits, enabled on startup etc. SIMPLE.

We had a reputable car brand dealer try to trick us into pathologically bad deal. First by hiding interest rate and offering us what amounted to 13.5% - which I called them out for and calculated their “mistaken rate”. Then already after the test drive, while starting to sign, they switched the VIN to a much worse equipped car (same price) hoping we would not notice!!! We did. In the end, we got what we came for, $3k under market and left them red faced.

Ham Update Late 2023, 2023-Nov-01 Wed, "QRZ.com update"

Mid 2023 I ran out of free time to commit to getting General and learning CW. I plateaued and lost interest :/ 2m nets didn’t bring any new info, ARRL newsline was the same reports of competitions of POTAs and of special events. FT8 chasing didn’t interest me. JS8 is really cool, but such limited bandwidth, that aside for Emcom end-of-the world scenarios, or chasing long contacts, didn’t captivate me.
