Picked up a SDRPlay RSP1b, and trying it out with a few configurations.
RSP1b on mac with SDRconnect which works fine, but the features are so basic it just doesnt have much use.
So moving on to Windows 10 and SDRuno. SDRuno is much more feature rich and I could see myself using it full screen on a 4k monitor when search the bands.
I found a video about near field coupling and tried testing TX and RX at same time on my antennas (OCF 40m and Comet CHA250HD). The RSP1B picks up 2.5dbm@5w and 11dbm@100w which is over the 0dbm limit (10dbm for 10sec bursts). Therefore, I will not be using the RSP1B when TX on my FT-710. I’m looking into a SDR switch to protect the SDR when transmitting.
Next is OpenWebRX+ which I tried on a Raspberry PI 3b, and though it ran the software ok, the CPU was just not enough, so the audio was very broken, and not usable. Some people say better heatsink and power supply will help, but I decided to move it to my Proxmox 8 server running on a Intel Core i5-12400 and using Ubuntu 22.04 in a VM and just mapped the USB RSP1B device to the KVM instance. It works great! It worked so well, that I also added my RTL-SDR and plugged in the Diamond X50, so I can monitor VHF/UHF antenna and HF antennas at the same time.
OpenWebRX+ is very feature rich, here are my favorites: Aircraft ADS-B decoding and showing on the map, Packet decode of APRS, FT-8/FT-4/WSPR background decode and PSKreporter.info reporting.
