@mcdanlj Sure, no pressure, just setting up that this might be an extended back-and-forth!

Broadly thinking, what do you think's best in terms of strategy for learning morse? So far, I've been referred to "The Art and Skill of Radio Telegraphy" which seems sufficient, probably just need to get to practice ASAP.

For low cost rigs, I've seen the (tr)uSDX which seems pretty promising. Any others you might recommend? Maybe something like an altoid tin project?

Getting started with #APRS question, I have a version of this cable but instead of the TRRS on the left, it's a USB connection (i.e. the one you'd use for programming with Chirp.) Can I use that other one with a Raspberry Pi to interface with my HT, or is this connector required?

@mcdanlj Definitely interesting, though I have a bit of background work before I can really get down to business on this. Plenty in terms of learning Morse and background on CW for example, there's a whole fascinating telegraphy/signals intelligence/operational excellence history there.

@mzedp another useful thing to check for functionality is the APRS 2m frequency of 144.390 MHz, it's packet radio so not always transmitting, but if you watch it a bit you should be able to see visibly frequency modulated packets, they're using AX25 encoding so it's a fairly bite-sized demodulation/decoding project after working with the FM voice transmissions on NOAA. (Though if you're in a rural area you might not see anything. aprs.fi has a viewer you can use to preview what you might get.)

@mzedp suggestion: you might try checking 162.4 - 162.55 MHz, that's where the NOAA weather radios are, they're a pretty useful "hello world" for SDR after one checks FM broadcast radio. Ref: https://www.weather.gov/rah/nwr

@K3LOE yep, but I should also mention I'm using custom firmware: https://github.com/egzumer/uv-k5-firmware-custom/wiki/FM-broadcast-radio-receiver

@mcdanlj @K3LOE Bummer about the TYT TH-9800, but it almost makes it more interesting to consider what gear would be necessary for this very specific application. Great resource too with the "Tech on Ten" link! There's so much to research, but such an abundance of notes and research to learn from.

@deacongeek Yup, Sangchris is a favorite of mine, although the 2 in Springfield are both within my biking range. It's interesting to see what can be done bike-mobile *and* car-mobile, but there's so much to learn :) It's great to see a local here on the Fediverse, cheers!

This sounds like it's exactly what I have been looking for: "The #NucleoTNC is a breadboard implementation of the Mobilinkd TNC3 using a STM32L432KC Nucleo32 board" complete with #KiCad design files! https://github.com/mobilinkd/NucleoTNC

Currently listening to broadcast FM radio on my porch with my Quansheng UV-K5 😀 it's actually kinda handy to have a multipurpose device like this beyond just amateur radio applications, like NOAA weather radio backup. Next up is to see if I can get some AM stations...

So there's also #Lincoln Trail Homestead State Park, and a Lincoln's New Salem State Historic Site near me, all within about 30 minutes' drive. Four all together, that sounds like a combo pack baby! What would doing a circuit in a day be called? A Top Hat Special? There's gotta be something better...

@mcdanlj I picked up a TYT TH-9800 (10m/6m/2m/70cm) but haven't actually operated with it yet, and I only have a 2m/70cm J-pole antenna to use with it so far. That's exciting though, I want to explore what's possible with an entry-level license and entry-level equipment, so having a reason to use this on an HF band is interesting. I need to take it up to the club shack, it sounds like! There's a pretty nice antenna setup there, so I should be able to try it out with a fairly plug-and-play effort

@mcdanlj thank you kindly for the guidance!

@w8emv Interesting, I hadn't considered the mobile phone angle, since I do have an extra one, and mounting a phone on a bike is a pretty well solved problem!

Second closest? Lincoln Tomb National Historic Site. Probably about the same in terms of operating etiquette!

The closest POTA site to me is the Lincoln Home National Historic Site. Wonder what the details of operating there are, hah...

Just signed up for #POTA.app, it's interesting to see #AWS Cognito auth in comparison to a lot of the sites & services I've seen so far. https://pota.app/

@hb9hox It doesn't necessarily have to be at the protocol level, but the last option is indeed what I had in mind. What gave me the thought is, in Debian for example, we might send an email with a plaintext portion, a GPG-signed portion, and then also include the key as an attachment. This is used in e.g. voting mechanisms. I guess the idea is that digitally signed "transmitted documents" can encompass quite a broad range of activities.

This is what they might call in modern parlance, a LazyHamWebToot
