Mike Bandpass filters are likely needed for the WARC bands whenever you intend to listen on those bands while transmitting elsewhere. Considering the value of BPFs in terms of their harmonic attenuat

/"While BPFs certainly do attenuate harmonics, this is all to no avail when the BPF is installed between transceiver and amplifier."/ I have a very hard time "buying" this statement. If a BPF attenua

Bob's, I think another way to say this is by example: If you feed an amplifier with a pure 7 MHz signal, the 2nd harmonic at 14 MHz will be only 6 dB down at the anode (or collector). The rest of the
