K3 - HAGCMDKT mod kit
Locked
 
|
Went to install the HAGCMDKT kit on #311. Interesting but all was already done except for shorting R33 and R40. Maybe there were interim fixes for this mod? By the way, C222 had already been changed to .1 uF for the CW Keying Rise Time Reduction. I needed to add the RXA board to the KXV3.

I installed the HW AGC mod yesterday on K3 325, it was not fitted.
I opted for the SMD components, and all went fine but I decided to use the standard LED as I was unsure of the cathode marking on the supplied SMD LED. This ought to be indicated on the instruction sheet I think. Also fitted the KXV3 RXA mod. All now back together and working just fine. Waiting for the second RX now and debating filter options. 73 Deni, F5VJC <quote author="N2TK, Tony"> Went to install the HAGCMDKT kit on #311.

Interesting that the mod levels of the board aren't reflected by the serial
number. Yes, I am waiting for the second receiver too. Going with the stock 2.7KHZ filter for the moment as the main use I have for the second receiver is listening to the "split" frequency. 73, N2TK, Tony -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of F5VJC Sent: Wednesday, May 28, 2008 1:01 PM To: [hidden email] Subject: Re: [Elecraft] K3 - HAGCMDKT mod kit I installed the HW AGC mod yesterday on K3 325, it was not fitted.

Hi Tony,
Nothing was required on your part. That is the factory version of the change that already has very low value SMD resistors installed for R33 and R40. 73, Eric WA6HHQ N2TK wrote: > Went to install the HAGCMDKT kit on #311.

Eric,
Tnx for the info. I just measured R33 and R40 - 6.3 ohms. At this stage does it matter whether I leave the shorts in place or should I solder these two resistors back?
