2023-11-03 — My Feedback to Radio World, EMCOMM: An Amateur Radio Robust Alarming System, SDR / 10 GHz Data Downlink, PacSat Project, and CubeSatSim - From 2023 AMSAT Space Symposium
About that comment by W6EM on the symbol rate Notice of Rulemaking, this is what I call a "kitchen sink" argument. He even brings in January 6 and claims that a this rule-change will be "Clearly a potential threat to our national security" (as did Rappaport in an earlier comment). When somebody throws this amount of crap at the wall in hopes that some of it will stick, I have to wonder what their *actual* objection is. I do hope that the FCC can see through the smokescreen emitted by the Rappaport faction.
We love the Raspberry Pi, but for many projects it's too much. The ESP32 and Raspberry Pi 2040 chips are great for low power and have enough processing capability to do AFSK and other audio modems. The Meshtastic protocol runs on ESP32 with a LoRa chip, for example. I can run a node (that can perform double duty as an MQTT gateway) on a single 18650 for over a day easily. Add a small solar panel and it can operate indefinitely. I think that the amateur radio community should consider some of these other chip options, especially for interfacing with mobile devices that can do a lot of the heavy lifitng.
As for the "No Winlink!" folks... 🙄 No one wants to bother with HF email.
Thanks for surfacing the new APRS to SMS service from NA7Q. I had seen some chatter about SMSGTE going offline but didn't pay close attention until now. Glad to see someone else step in.
Steve, check out the Richie Brothers auction site. The currently have 494 'Light Towers' in their auction inventory.

Thank you for sharing all of these sections (replying to the Cheap Data Radios section, but loved the Satellite section and many more!)
