I made a satellite pass match maker to find #hamradio satellite passes that cover two locations simultaneously. Very basic UI, and a bit slow, but functional. Enter your grid(s) to try it out satmatch.com #MVP @sat_match #K5EM_KH6
Last day to order a SotaCAT this year! Get WiFi control, click-to-tune spotting, and SotaMAT integration on your KX2/KX3. We have a few in stock still; any in-stock orders today will ship tomorrow, then we're taking the holidays off. store.invertedlabs.com

First time over 100 countries in 24 h! With the amazing PDSDR, monitoring 16 FT8 frequencies simultaneously. Just look at the coverage. Many countries I've never seen signals from before. MLA-30+ loop antenna here in Vancouver. @k5em @K3TripleR

Switched both Pavel SDR receivers to run from SparkSDR and report both FT8, FT4, and WSPR, and the results are pretty much identical to the pair of Hermes 2 Lite skimmers connected to the same antennas. The onboard decoder works well, but only reports one mode at a time.
Just finished building a set of Pavel Demin’s new low-cost receive-only SDR boards! Exciting to see how they perform alongside my Hermes2 Lite skimmers.
If you're interested in one of these and live in North America, ping me, ideally via my email on QRZ. I have a few extras that are fully built up and tested including the QMTECH XC7Z020 board that I'd be willing to part with.
Here's Pavel's original post on the RBN-OPS group, which also has all the details in case you want to order and build your own: groups.io/g/RBN-OPS/topic/lo…

Lots of missed sleep, long hikes, long drives and crazy amounts of editing, but it's finally done.
