My VNA doesn't seem to be working but occasionally, I can get a reading on it. Thinking that it might be me, is there a way to reset the nanoVNA back to it's delivered format, in case I have done something that is causing the problem or is there a test that I can do to prove to myself, that the device is actually working?
Any suggestions or help would be appreciated. I have calibrated it a number of times but that didn't seem to make much difference. I have connected to nanoVNA-Saver and can set frequencies etc but still don't get any results if I connect it to an antenna for 2m and set the device to scan from 140mhz to 150mhz. I would have thought that I should see something.
