[R-390] Low sensitivity on 7-8 Mhz band

I have the same problem with my 62 Amelco that I rebuilt.  Chuck Ripple told 
me that some R-390's exhibit that problem on the 7 mhz and he had no 
definitive explanation.  Next time I pull the radio out on the work bench I 
plan to try and improve the situation.  If you learn anything, please pass 
it along.

Thanks
