[Johnson] Valiant with xtals

[Fabio Liberatori]

   Hello all,
                 I have just got a try with my just-arrived 7143 MHz 
xtal  (for 14286 MHz AM operation) but no luck...
I put the xtal in its socket (on n° 3 and n° 5 terminals), as stated 
in  the manual...
When I push the PTT It seems it goes for few milliseconds, just a 
spike, then it goes down...

I will check again where the problem is, but any help will be very 
appreciated, my brain is getting very poor...

     73 de I0LBE,
         Fabio
