Paul, Roy,Thanks the replies. In the past I have always heard myself. So there must be something gone wrong with my system. I will have to check out everything. Thanks again for the suggestions.73s, Jim, Ke4kol

The 910 is generally very effective at filtering out harmonics from the transmitter. However, harmonics can be generated beyond the transmitter by poor connections, bad feedlines, or a damaged antenna. Check your entire antenna system to make sure there are not any problems.

All,Has anyone else had the problem of not hearing your own downlink when working SO-50? In the past I was able to hear myself, but lately I cannot not. I don't know if I change some setting or that the Icom is going bad. Thanks for any help. I appreciate it in advance. Jim, Ke4kol
Jim,
With SO-50, especially, this is very common. The 2m uplink has a harmonic very close to the downlink, which if not filtered out, can wipe out your local downlink whenever you are transmitting. I'm not familiar with the 910 enough to know how well it does at this, though.
You were getting in fine this morning, though (not sure if you copied my QSL)!
