I would like to shorten the AGC response time in the K1.
I see there is a mod of changing C31 on the RF board from 2.2uF to 1.0uF.
I have a 1.0uF tantalum cap and was wondering if there is any problem with
replacing the 2.2uF with it since it is not a polarized electrolytic.
Thanks, Mike K7MH
on some little projects like this.
Thanks, Mike k7MH.

ways. After touching it
and some other joints, I re-peaked the filters in receive and found that the
2nd premix filter of each band peaked in a different place. In transmit it
came alive.
Very cool!!
Thanks again, Mike K7MH.

per the
voltage table instructions.
I do not get a reading on pin 6 of P1 on the filter board which should be
the premix signal output.
Any suggestions would be much appreciated.
I will double check some things.

It is the two band board with 40 and 20 meters.
I have looked over the filter board several times and re-soldered some
joints just to be sure.
I will look over it again.
I used the pre-wound coils but will look them over again and make double
sure the right one is in the right place.

I don't have the KAT1. Just the basic K1 with 2 bands and the backlight.

.
The receiver works ok and all the voltage and resistance measurements listed
in the
assembly part of the manual and those of U9 Q8 and Q7 are all good.
