Mode J Desense Filter
This type of filter can be used in a Mode J satellite station uplink on 2m, downlink on 70cm
Noise suppression with X-phase II
QRM eliminator, of radio interference
Narrow Band-Pass filter for HF
In homebrew equipment designedfor these bands, a narrow band-pass filter NBPF that attenuates frequencies above and below
QRM Eleminator
I have some times problems with local noise on the lower bands, this wiring diagram X-Phase help really a lot
