K2 Problem

Glenn Haffly
There is a problem wih K2 # 4869.
On 30 / 20 meter bands there is no received
signal. Using an rf generator a signal can be heard.
The following have been checked :
#1 Reviewed solder joints in LP and BP areas. None found.
#2 Recounted turns on L18 , L19, L20. All correct and no cold solder joints.
#3 All caps in LP and BP correctly installed.
#4 Relays K4 and K9 installed correctly.
#5 All other bands operational on Rx and Tx.
#6 Per Don checked soldering several times.
Observations: Using the RF generator , used it as a probe in the BP area.
The
signal could be heard at every cap location either on 30 or 20 except at
C25.
C25 was replaced with a temp from the junk box. No improvement noted.
Also using a screwdriver as a probe with a finger on it in the 30/20 BP area
an improvement in signal strength noted. In tuning around on 20 there is a
birdie at 14.000 and 14.360.
Any suggestions would be welcome.
