Thanks for all of the replies on the drift problem. I ran some tests 
yesterday and recorded the drift.
Turned on the TR-7 at 3:59pm to 7.185.0 mhz
At 4:17pm the frequency was 7.184.9 mhz

Switched to 20 meters at 4:18 pm. Frequency 14.185.0
At 4:32pm it still was 14.185.0

At 8:19pm changed frequency to 7.208.0 mhz
at 8:52pm the frequency was 7.207.8 mhz

At 8:52 changed frequency to 7.204.0 mhz
At 9:36 the frequency was 7204.0 mhz

Looks like there may not be a problem after all. Seems like some days it 
drifts worse than othe days. May be heat related since I have the rig in my 
garage in a cabinet and it is pretty warm until the A/C cools it down.

Regards, Troy, k5oh
