[Premium-Rx] OT But: TMC GPR 90 RX (

[Ka9p at aol.com]

Hi, has anyone worked on the second conversion oscillator subchassis on a  
GPR 90?
 
I stumbled across one that doesn't want to work on the double conversion  
bands, and it seems like the 3500 kc second conversion mixer xtal isn't  
oscillating, but it's on one of those pesky subchassis that looks like a bear to 
 get out (perhaps requiring unsoldering a while lotta stuff, which may be 
why no  one fixed it)
 
I was wondering of per chance anyone knew a trick to do this, or the  
appropriate reflector to try.
 
At least it doesn't have proprietary chips I can't find :)
 
Thanks and 73 Scott
