[R-390] Meter Levels

[gary.biasini at shaw.ca]

Larry,

 

Thanks for your insight. 

 

On the second issue, I have confirmed that nothing is connected to switch (S105) position 2 and that all the wires on the meter (M101), S105 and on the pot (R104) are identical to another R-390a that I have.  So, I must assume that somewhere in the wiring bundle, there is a short between wires that shouldn’t be shorted.

 

Thanks again.

Happy New Year to all. 

Hi Gary,  I believe that #1 is normal operation.  And, #2 is due to a line mtr switch problem.  One end of the meter is connected to nothing, normally preventing any deflection.

 

Regards, Larry

As my first post of 2023, I wish all a very enjoyable new year.



On an EAC R-390a s/n 3122, I have noted the following:



1.      On a very strong BCB station with a 20 foot indoor longwire antenna,
the carrier level meter in AGC deflects to 40 but is 0 on MGC.
2.      Even when the line meter switch is "Off", the line level meter
noticeably deflects.



Do these observations suggest any issues that come to mind?



Thanks.
