[Elecraft] K3 gain changes with filter selection

[N3XX]

Sorry, I just read your message more closely, and it looks like you have 
already been through those settings.  I'm not sure what else might be the 
problem.  Maybe someone else has an idea.

73,

>>I have a K3 with three filters, 2.7 KHz (FL1) , 400 Hz(FL2)  and 200 Hz (
>>FL3) .  When I reduce the bandwidth from 4.0 KHz, the radio performs as
>>expected EXCEPT when the the different filter switches in. When I reduce
>>the bandwidth and it switches from FL1 to FL2, the receiver gain goes up 
>>at
>>least 12 dB. Whe I further reduce the bandwidth and the radio switches frm
>>FL2 to FL3,  the gain reduces to that of FL1.  Filter gains are set at 0
>>dB, 1 dB and 3 dB for FL1 thru FL3.  This happens in USB as well as CW.
>>When I use FL2, I need to turn down the RF gain. What's happning?
