[ICOM] Icom 706 and possible relay problem-advice

[John G.]

I have an Icom 706 original which I picked up around 19 month ago and really like it.  I have noticed for the past few months that the receive seems to drop at times on certain bands-it started on 12m and now occurs on 15m as well.  If you click the key or mic to quickly put it into transmit the receive comes back. To me this sounds like a dirty relay or one that is going bad, but it does seem to not be as bad after the rig has been on a while and probably heated up. It doesn't seem to affect 17m or below, or 10/6/2m either.

Any ideas as to what might be going on and how much it would cost to fix if necessary?
