I am running the service monitor into the duplexer, not an antenna. I don't see how desense could be the problem with the tx off and a service monitor for a source.
I am using the monitor for a source and going thru the duplexer and testing, then bypassing the duplexer. Through the duplexer I have this problem, not direct. -----Original Message----- From: "skipp025" <[EMAIL PROTECTED]> Date: Tue, 22 Mar 2005 17:14:08 To:[email protected] Subject: [Repeater-Builder] Re: Better RX with feedline partailly disconnected? > "Michael Singewald N1PLH" <[EMAIL PROTECTED]> wrote: > 220 Hamtronics receiver (very old, no labeling on > the board). The early receivers don't have a very selective or dynamic rf front end. Blocking and desense is a common problem with the early type less protected receiver front end circuits in repeater service. A good fix would be to install the Hamtronics HRG-450 Helical Resonator Amplifier in front of the receiver. You can pick the Helical unit with or without a preamp. I bought and used the preamp included HRG-450 Helical on the same exact receiver and it worked very well. Adding a Helical Front end pre-selector makes a lot of early receivers semi usable. They are a welcome addition to converted Midland 13-509 and Clegg to repeater radios. cheers, skipp Yahoo! Groups Links Yahoo!
