[TenTec] 937 PS-troubleshooting-(blush)-TNX TEN TEC--Lesson Learned

[ARDUJENSKI at aol.com]

RADIO: 555 SCOUT
 
ISSUE: Chirp on the CW signal.  Voltage at output of 937 was dropping  from 
14.2 TO 10.3
 
LESSON LEARNED
 
Well, after checking several potential problems and not identifying the  
culrpit I tried an Astron 7 amp and same problem but noticed meter light was  
dimming. I made a call to TEN TEC thinking the problem may in fact be the SCOUT  
and I may have to ship that out.
 
I talked with GARY at Ten Tec and with an AH HA and a rub of the chin, Gary  
said he thought he knew what the possible problem was-- RUNNING MORE THAN  50 
WATTS on the Scout. I had readjusted the RF CONTROL from 5watts and just  
turned the adjustment all the way clockwise. Well dang it HE WAS  RIGHT. With 
power meter and dummy load in hand backed off the drive and  everything is working 
great.
 
ONE MORE THING: Gary noted sometimes the caps to the final C1 and C4 could  
have been the wrong value or need replacing with 100v 104s (0.1). Thankfully  
that was not at issue
 
I thought I would pass this LESSON LEARNED along. Not quite as bad as  not 
having it unplugged  but close (smile)
 
Thanks to all who have responded and especially GARY AT TEN TEC
