[Drake] T4Xc Troubleshooting

[Ka9p at aol.com]

After spending a fair amount of time getting a Dayton T4XC "working" radio  
working almost, I've got it down to one last problem.
 
The oscillator doesn't run on 40.  I've great ocillation and power out  on 
all other bands, and I've swapped a known good crystal with nary a whimper,  
and thought before I started tearing into it I'd ask if anyone had a good 
first  and second guess of what to try first?
 
Thanks a lot, Scott
