Issue with running at 146.5MHz or Below

[G8YTZ]

Hi,

The setup is Jetson Nano with Portsdown Control and Lime Mini (all up-to-date) and Minitiouner Rx PiCam and USB Mic on the Jetson.

I'm getting good results at 70cm and above, very stable and runs for many hours without issue, but at 2m and below the output is very flakey, the on 146MHz Lime Mini sometimes produces no RF at all, sometimes just wide-band noise and on occasions a decent signal. No issues in running the Lime direct from the Portsdown at 146.5MHz (without H265 of course).

Any idea why the lower frequencies seem to have a problem?
