Ok Erik,
Starting taprvna
Connect com3 says no vna connection to com3
Second time it connects, sometimes the nano screen turns white and everything hangs, sometimes Connection is ok.
If so, calibration runs fine and I see the nano display jumping through the frequency steps.
Scanning 200khz-200Mhz runs also (frequency steps ok)
But no S11 magnitude graph, Line stays on 0 dB, also S11 SWR graph.
I have connected a endfed longwire antenne for 7, 14, 21 ... MHz. To port CH0
Thanks anyway for your efforts
