Re: Bandpass filter

 

You can do multiband quite simply with juat two sets of filters :
1.? Make on set tunable from 14 mhz to 30 mhz with a ployvaricon or any two section broadcast variable capacitor.
2. The second bandpass filter can tune 3.5 to 7 mhz.?
A pair of dpdt relays and air coils should do the trick.

Thank you for the advice. I already have a bunch of low pass filter boards from kitsandparts a few years back, so just need the bandpass units. I was looking at the qrp labs board, so that may be the way I go. I do have a signal generator? frequency counter, and scope, so should be able to set things up with that.
