pirate radio, first SSTV decode
The decode is from a transmission of "Wolverine Radio", a pirate station on 4055 KHz monitored from the N4TVC KiwiSDR in Burke, VA.
I used the "RX-SSTV" software to do the actual decoding. The sound of the signal is very much like what a fax machine sounds like, with a rhythmic beat as the scan lines go across.

This copy updates my 1983 version (!)
Combined with the world network of KiwiSDR and WebSDR installations this makes for many hours of DX listening fun.
I have a little ADS-B receiver, and for the life of me I'm not sure why its reception has gotten noticeably worse over the past few weeks.
I've re-imaged the operating system and swapped out a Pi 2 for a Pi 3, and still I get hardly any planes spotted where I had previously gotten more.
It's hard to debug mostly because the time of day I like to work on it is at night, when there is a lot less traffic. The easiest way to test it is just to move the receiver around the room and wait a minute.
Working on my portable operations. I took a ladder line antenna that I had in the attic, rolled it up, put it in a ziploc and put the ziploc in my bookbag. This a.m. for the 800a net on a local repeater I did my usual walk, and went to a local park where I put the antenna in a tree. Much better reception with that! Gotta try that again next week.

read the birbsite thread for more details, I don't know if K7al_L3afta is on any Mastodon.
Looking for SDR hardware suggestions, now that I have #PiSDR up and running on a dedicated Pi.
Hoping to be able to have wide enough bandwidth to see all of 2 meters, 144 to 148 Mhz. My RTL-SDR tuner sticks really only cover half that spectrum.
Up and running!
Next step is to hook up a Bluetooth speaker for audio. Reception confirmed with GQRX, the RTL-SDR is hooked into ladder line 2 meter antenna in the window.
Anyone else here running #PiSDR ? I'm burning a new image for one of my Pi 4's. There's plans for a newer Ubuntu 20.10 based support, and to boot on the Jetson Nano, so this is mostly to get a taste of things.
Net on #N8DUY repeater 145.15- at 800a Eastern. 6 of us on, about 40 minutes. Very friendly bunch and all people I haven't talked to before. AA8VS Chuck ran the net this a.m. I think this is a daily net.
I'm pretty sure I'm the youngest of the bunch, and that everyone there is retired.
Five people on the Clinic zoom right now.
