Interesting... Wonder what the measured insertion loss of one of the TOKO
filters is... Although physically much larger, there is a 4 section
helical resonator assembly buried in UHF Motorola Motrac FM radios that
tunes up beautifully with a 222-225 Mhz passband, with around 10dB
insertion loss.

Likely won't pull far enough to filter the LO, but what the heck...

Look in the junquebox for the TFD 6080A!!!
