I assume that you are always making this test after hitting A>B two times in quick succession. Listening to daytime 160m noise I set both RF gains to max and adjust the AF to get equal irritation levels in both speakers, I get the same 11 oclock for both RX. If I then come up from RF min to where

Joe (W4TV) Yes I have performed the gain calibration many times on both receivers using the K3 Utility with the XG2. I recently did it after loading the new K3 Utility that supposedly fixed some issue about writing receiver gains to memory. So now you make two people whose RF gain tracks. I can't

I followed the procedure Markus suggested with no change to my K3 RF gain tracking between main and sub Rx. I have been listening through the 2.7 KHz stock filter in both receivers with identical PRE and ATT and both filter gains set to 0 and identical IF filter bandwidth settings and both receiv

I always experienced a significant difference when comparing main/sub signal levels. Mike's message triggered me to search for the cause. Step 1: Changed RF/AF controls back to independent: SQ MAIN = 0; SQ SUB = 0; SUB AF = nor. No luck, the sub signal level was still much lower than main. Step

[Elecraft] K3 Sub RF gain

2010-10-21 Thread Mike Scott
I have noticed a difference in behavior of K3 main and sub receiver RF gain behavior. Listening to a strong signal over S9 on the main Rx as I turn down the RF gain the signal disappears around the 11:30 position. On the sub receiver the signal is still fully copyable with the RF gain full cou
