[Elecraft] Question about the K1 AGC Response time mod

2012-01-18 Thread K7MH
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

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. -- View this message in context: http://elecraft.365791.n2.nabble.com

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. Mike K7MH. -- View this message in context: http://elecraft.365791.n2.nabble.com

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. -- View

I don't have the KAT1. Just the basic K1 with 2 bands and the backlight. -- View this message in context: http://elecraft.365791.n2.nabble.com/Voltages-for-Q5-and-U8-tp6825928p6829699.html Sent from the Elecraft mailing list archive at Nabble.com.

[Elecraft] Voltages for Q5 and U8?

. 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.
