Ross, your system seems to have GNU Radio version 3.8.1.0 installed. If you are running Ubuntu 20.04 (or derivative), then it would be from an Ubuntu repository. The request for GNU Radio version 3.7.

Clint, the issue with FIR (non-ringing) filters is that the narrower the bandwidth, and the sharper the skirts, the longer the processing chain (the number of taps) will be. There will be limitations

Thomas, it looks as if you're going to have to suss it yourself. The reason that there is no ready-made cable is that the ACC socket is also used for CAT control, and if one wished to keep that , then

Tony, it may help to think of it this way. A Duo does not have ALC, nor does it have a slow-start heater supply, nor a thermionic valve output stage. The traditional reasons for needing ALC in a trans

Patrick, the delay is due to digital processing, required for audio filtering. It's inherent in the technology. There is also a delay with analogue technology, but it's much shorter and generally impe

But Alberto, you know that no mathematician is ever happy until she or he has overloaded, for some apparently rational reason which, never-the-less, makes no sense to anyone else, existing mathematica

Charles, you're 5/9 on the 13th and again on the 15th! This is a low traffic group. 73 Robin, G8DQX

Alberto, my apologies. It was after the witching hour of midnight, and Intelligam appears to have been prorogued! All is now OK. Robin, G8DQX

Not so much the quality but rather the quantity—there was no photo associated with the post! Robin, G8DQX

John, the chances are that the interconnect to the changeover relays in the TL-922A has damaged the output transistor in the FDM-DUO, unless you have added some protection circuitry. The manual to be

Patrick, comments in-line below: Robin, G8DQX My experience with Pulse Audio Volume Control (PAVC) is that there is a difference in behaviour between when it's open and when it's closed. If you close

Patrick, if you're going for the dead simple approach, don't forget to turn the nasty OS sounds off, if you haven't already done so. Alternatively, the PulseAudio Volume Control (package pavucontrol)
