OK, reporting back as requested.
Here are the results for the band pass filter.
Sorry it has taken so long but life is pretty hectic (won't bore you with the details).
The Mini is configured for 20m.
Only T1 and C1 are installed (C5 & C8 are not used for the 20m configuration).
The measurement setup is like this:
NanoVNA was calibrated and C1 was adjusted to put the peak in the CW part of the 20m band.
4.13 dB insertion loss seems high:
There is 10.22dB suppression w.r.t. peak at 13.48MHz.
And 4.8dB suppression w.r.t.? peak at 14.58MHz.
The shape is different than Hans' photo in the manual (I measure the notch below the passband and he measures the notch above the passband).
Seems reasonable to me but I would be glad to hear your opinions.
LPF is next.
73, Mike KK7ER
