[VHFcontesting] Doorknob Capacitor Resonances

[Steve Kavanagh via VHFcontesting <vhfcontesting@contesting.com>]

I'm evaluating a low pass filter (for 6m) I acquired recently, which does a 
dandy job up to 250 MHz or so, but it has a few spurious responses between 300 
and 500 MHz.  It behaves like the 50 pF/7.5 kV and 100 pF/5 kV doorknob 
capacitors it uses must be self-resonant in this range.  Can anyone confirm 
this?
