[Elecraft] K3 Main RF Gain problem

[Wes Stewart]

In working with Lyle on earlier versions of the rf calibration I saw some of this same action.  In some cases, the s-meter wouldn't even reach FS at min RFG.

You might try backing off to factory defaults and starting over, making sure you have the latest utility.

RF Gain calibration completed as per manual no problems seen in the
calibration procedure.



If in Config menu >>Smeter OF or other Smeters menus and I move
the RF Gain the Smeter will respond as you would expect.(this is just a
curious sidebar that is probably not useful info)



In normal operation AGC OFF or ON S or F , PRE ON or OFF, ATT IN or
OUT, ALL MODES ALL FITERS   I get a gain increase in the main rcvr at
the 9:30 position of the the main rf gain. 



Since the RF Gain calibration works for the sub reciever and the RF
gain and S meter on the Sub rcvr  work correctly I am beginning to
suspect the JFET  IF Amp and associated circuits of the main rcvr.
