"is it necessary for you to be able to talk through the repeater using one of them to talk and the other for receive?"

It is if, like he said in the original post, he wants to use one HT to talk with his sister who is using the other. Presumably they will not normally be standing next to each other.

Any update on solving the problem?  when checking several of my radios, I put them in low power mode, i.e, 1/2 watt than both radios can be in the same room with out overloading them. As stated before, set both to the same simple freq and verify that you have communication between them.
No they still wont talk on a repeater (so far) but on a non-repeater frequency (145.555) i turned the power down on mine and they could talk so i still need to test it on a repeater, which i will do soon cause i know someone who is a ham and ill ask him to help. but hopefully turning the power down fixed it.
Thank you all for helping!

Simon:  "De-sense" is probably a new term for you.  What happens to most receivers when a strong transmitter on an adjacent frequency is nearby is that the transmitter's strong signal overloads the receiver stages and prevents it from receiving normally.   Based on what you have shared with us (that both radios independently work through repeaters) pretty much confirms the diagnosis.  You could confirm it yourself by connecting one HT to an outside antenna about 25 feet away.  My guess would be that then you would be able to hear the repeater transmitter in the other HT as you are transmitting.. probably the squeal of  audio feeback too, if one is lying a few feet away within earshot.


Don't worry.  If and when you separate them during actual use, that won't happen.  Remember a valuable lesson:  If amongst a group of hams with HTs, at a club meeting or hamfest, when you transmit, none will likely be able to hear a distant repeater on the same band as your HT..
