SDR Television
- Found and fixed an unused massive memory allocation (up to 10GB), may have caused systems to freeze.
- Fixed fatal bug in matched filter array allocation.
- Changed the default transmit bandpass shaping filter roll-off to 0.20 in transmit and receive. Please look at the images below and apply the change.
SDR Pluto
- Now show the AGC gain and RSSI.
- Added Default link to select the recommended gain - Fast Attack, 0dB visual.
Known Problems
- Add support for tracking transmissions with (?) non-standard PCR data, example is G8GKQ.
- Using Pluto & variants, sensitivity is not as good as a NIM (hardware tuner). Will compare with SPECTRAN ECO in a week or so.

After too much grief, I've decided to stop using Wi-Fi to connect the small NUC systems in the computer room to my network: DX Cluster (Ubuntu) SDR Server (Windows) User Forums (Windows) These servers are in constant use, causing the wireless transmitter on my TP-Link AX50 to fail. By switching over to a wired network there's less demand on the wireless transmitter and the whole network has become far more reliable. In future I will only use Wi-fi when there's no alternative. I'm keeping a spare router ready just in case the AX50 fails.
