Testing 2 Radios Against Same Repeater

[WSJD886]

Totally newby here, so forgive me if either dumb question or answered elsewhere and I am not searching right.

• I have 2 identical radios (Baofeng UV-5G+'s) that I have configured to talk to the same repeater, one for me, one for my wife
• I have programmed them with the same channel information (used the Baofeng software, loaded same profile into each and confirmed)
• I am trying to test one, then the other, to be sure when I talk on one I hear it on the other, and vice-versa
• When I talk on one, I do NOT hear myself on the other
• I DO hear back from someone on the repeater saying they hear me loud and clear

I am wondering if having both radios in the same room is causing one to overpower or cancel out the one listening.

Anyone have any ideas?

Yes. get them at least 50 feet apart and try again.

Asked and answered in the same post

It's not usually a problem when the receiver and transmitter are on the same frequency, but on a repeater, where you're transmitting on 1 frequency and listening on another, the transmitter will 'deafen' the receiving radio if they're too close.

I actually did similar testing today w/ a radio I'd just installed in a car in the garage, and my kid standing out by the street to let me know how I was coming through.

Yep, 50 ft, 100 ft or farther.  Depends on how sensitive your radio is to desense.
