Jim, I use Linux Mint 19.2 Cinnamon on my Chromebook and I believe I had trouble running nanovna-saver because qtxcb was missing. Try installing it with "sudo apt install qt5dxcb-plugin" and see if

Re: SimSmith - great, not only for Measuring resonance from coax far end.
Dig further back into the matching system. In our modern transceivers, the match begins at the collector / drain of the output devices (the PA). There is typically no attempt to do conjugation at that

Re: Amplitude calibration
Good morning Alan, I did as you suggested, I know where the issue is now. I neglected to take into account the dynamic range of the instrument. The filter is a 40 meter filter down -78 dB so I was in

Re: Amplitude calibration
Filter response is very dependent on terminations. Higher load Z than filter designed load will increase coupling between filter elements, widening bandwidth and usually increases loss. Lower load Z

Re: New version of NanoVNA-Saver: 0.2.1
Measured 50 Ohm and 75 Ohm, the results were pleasing. I'll tell you how- The CH0 channel in Format is REAL and the CH1 channel is SMITH, the frequency is set to 50 kHz-10 MHz. I connect the line to

Re: New version of NanoVNA-Saver: 0.2.1
A feature suggestion: Is it possible to get a delay in picoseconds directly from TDR. That would make it easier to get a starting point. I tried several values from 200ps to 50000ps and did not get a

Could this be resolved by using a proper (read: not cheap) N cal kit? If N connector is only an option and not forced on all users, it seems to me that it would be acceptable to expect the user who

Re: SimSmith - great, not only for Measuring resonance from coax far end.
Hans, because of real world losses, in a system with only one matching network, instead of a lossless system-wide conjugate match we can only have a conjugate match at a single reference plane. In
