Trying to set up a repeater and looks like ive got issues with Desense.
Basically I got a cavity filter like this one here:
(link removed- Please read the forum rules) 65W Duplexer UHF 6 CAVITY DUPLEXER for radio repeater N connector UHF Duplexer…
And its running a pair of baofeng UV5R radios, with its TX set going through a Btech U25 booster.
Its working fine with signals in close range, but signals further away, while still coming in strong, wont receive once the set starts transmitting.
I did a test, and had the other person talking and as soon as I keyed the PTT button, it went silent, I could not hear any noise from myself transmitting, but it was cutting out.
Any ideas? Only thing I havent tried testing is reducing the bandwidth to NFM instead of transmitting on FM band.
Channels are UHF band 5 Mhz apart. High band is RX, low is TX.
