Hi again Roger;
Forgot to add... I measure -7 dBm out of the Ch0 port of my original NanoVNA v.3.1 board running Hugen¡¯s H -AA firmware. This is 6 dB higher than edy555¡¯s original 900 MHz firmware release. Bottom line... It appears Hugen bumped the power in his H version to trade off linearity for an improvement in dynamic range.
