@KC3JXQ congratulations are in order!

How did you study? I would like to get my extra but the question pool is a bit daunting

Biked across town to talk to W8TAM who gave some good advice on attaching an antenna to my bike rack. The suggestion was for an NMO mount which would easily handle 2 meters radio and could be adapted with a different antenna to also support HF. When not in use the antenna could detach, and I could still carry groceries with it attached.

This is the recommended mount for my application, from Breedlove:


I need to measure to make sure everything will fit on the bike!

@M0YNG @aprsbot

By the looks of it I tested it once, but I forget how @aprsbot works! Is there a brief writeup?

Yes! I see


which describes how it all works.

Is there a working APRS to Twitter, APRS to Mastodon, or APRS to email gateway?

The docs I have found so far suggest YES for APRS to email, via EMAIL-2, but the docs are also old.

It would be great to be able to post a message here via RF!

@M0YNG I would love a sticker, and can send stickers in return post. (Past and future contributor.)

starting a co-op; seeking guidance 


I know two software co-ops: Vulk Co-op in Austin TX, and II Co-op in New Zealand. I'll bet you could talk to Lucina at Vulk and get some ideas, and Hippie Hacker at II is great too.


I miss Napster too.

My replacement for it is radio - specifically finding stations either locally or via Internet that have real DJs and local music. WWOZ New Orleans is community radio, as an example, which always repays a listen. You have to dig a bit to get away from the Clear Channel or Audacy pre-programmed nonsense, but generally the low end of the FM dial has lots of good listening.

Looking at this DMR rig from Radioddity as a possible base station + occasional car radio + experimental bicycle rig.



It is an obvious question, and I will check those when I have a little time. I don't remember reprogramming anything, and it has worked in the past, but it's a radio so something might have changed without my knowing!

For some reason, when I call the N8DUY 2m repeater on my RD-5R, I get no response. Calling N8LBV on 70cm on the same radio and on the same tower works just fine.


I do have a pannier rack; haven't touched a magnet to it yet, but I think it's all aluminum. I also have a suitably sized piece of steel plate that would fit in my panniers which I could haul outside and test.

Next step only is to locate a 2m/70cm mag mount from someone's go bag car kit and see if I can repurpose as bicycle kit.

Looking forward to the 8:00 a.m. net this morning on N8DUY 145.15 Ann Arbor MI, which I plan to operate bicycle mobile.

Sunrise today 7:08 a.m., sunset 7:56 p.m. The days are getting visibly shorter, but I still have 1 hr 52 minutes between sunrise and the start of my day at work.

Still noodling about how to get a good antenna on a bicycle for 2 meter operations. Considering a mag mount to a back rack, or a dipole of some sort inside a pool noodle affixed crosswise.

73 de W8EMV/BM !

Considering a better antenna for my bicycle mobile operations. I have a hunch that a mag mount could work, with a ground plane attached to the back rack of my bike. It would be more compact than a rollup J-pole + bike flagpole.

Look what came!

I have @alex stickers!

Would you like one?
I think it would cost me around £2 to send internationally, so if you were to donate at least that much and give me an address to send it to I will try my best to send you a free sticker to say thank you for helping to keep our instance running.

PayPal to cq@m0yng.uk should work...
You can make an ongoing contribution via liberapay.com/M0YNG/ too

Thanks again to @Anna for her great art!

Operated the morning 2 meter net on N8DUY bicycle mobile. My timing was good to be at a park overlooking the Huron River with some good elevation during the net.

Next to research what I would need to get a flag for the back rack and attach a roll up J pole antenna to it for some better tx.

Operated bicycle mobile this morning and it was a great deal of fun.

I have a Raspberry Pi 3 connected to a RTL-SDR tuner stick, monitoring 1090 MHz for aircraft ADS-B and feeding to ADS-B Exchange and a commercial flight tracking site.

I'm close enough to Michigan Stadium to hear the planes going over on game day, but my ADS-B receiver doesn't track them. ADS-B Exchange is tracking one flight, and it says the data source is "ADS-R or UAT".

Is this the 978 MHz band in use? If so, and if anyone's listening to that, do I need a second Pi or just a second radio?

Do you keep a scanner going, and if so, what channels is it tuned to?

I'm monitoring 5 or 6 local 2 meter and 70cm repeaters with an old Radio Shack Realistic Pro-34. It supports 100 channels, but I'm not going to need them all. The radio was $2 at a reuse store, and I put $15 into getting a new power supply for it so I didn't have to futz with batteries.
