I have a QPSK & BPSK packet radio link to several other stations via the QO-100 satellite narrowband transponder, using a couple of Pluto SDRs and in some cases a mix/match of RTL SDR dongles and 70cm radios with transverters.

Only a small group (4 so far) doing it, but we can be heard on the WEBSDR hosted at Goonhilly Earth station[1]

Due to small dish sizes on RX (10GHz) we are keeping it simple and open at 1200 BPSK and QPSK 2400 with IL2P[2][3] for FEC+RS robustness, and not even close to the 2.7Khz max permitted bandwidth.

This is very cool. I wish those of us in North America had access to a satellite like this

Aww yiss. Nederkunst.

Thats amazing and also kinda wtf because drunken parties are the norm, so cultural alcoholism is a bonus.

The Modarchive[0] is still around, too. The reviewer’s (shared) password used to be since1996

We’re still using their cousins on amateur radio lol

The use case for UUCP-style forwarding on amateur (packet) radio platforms makes perfect sense. Like the early Internet (ARPANet), many packet stations do not operate 24/7 for various reasons such as changes in propagation or the operator using the radios/computers for other purposes. The store-and-forward messaging paradigm is best for sporadic networks such as this.

I’ve felt this way for a considerable time too. In retrospect, it has now been ten years and yet still nothing has really changed, which I am kinda glad.

A friend of mine is building a Raspberry Pi ISA board so I’ll have to ping him on how it’s going.

I had one of these type of jackets and quickly found that they set off IR-controlled hand wash taps in the toilet facilities at a certain airport.

10/10, would recommend for very clean hands.

Stunning stuff. The dark sunspot in the foreground and the one behind the tangle of plasma is intruiging.

Keeping an eye on this http://websdr.ewi.utwente.nl:8901/fullday/ for the effects on the HF radio band, it might be quite interesting.
