Don
I checked T7.  It is installed correctly.  The radio appears to work fine.
Is there something wrong with the s-meter settings?

Thanks

Hi

These S-meter settings sound like the readings when T7 is reversed. I have 
seen this several times and it makes the AGC and S-meter flaky as well as 
the sensitivity low. However you can make the radio appear to work although 
it just seems not quite right. The red wire winding should be closest to the

IC U12 and the green winding should be closest to the jumper W3. Looking at 
another way the red winding should be in pads marked 3 and 4 and the green 
in 1 and 2. This may not be your problem but it is worth a look.
