[Elecraft] KBPF3A switching frequencies and performance

[Russ Tobolic]

 Thanks Ben, I didn't think of that.  Now when the KBPF3 is not inst There is no difference in signal level when transitioning from 1.700 to 1.699999.  And when I set the KBPF3 to nor (and reboot) there is a definite drop of 5-7 S units at the 1.700 transition point and also at the the 2.11 to 2.10999  transition.  So there is definitely something in the low band signal path that is attenuating the signal.   I'll also do some checking at the other freqs.  I guess it's time to drag out the scope for some signal tracing which should be fun with SMDs and my old eyes.
