KDVR3 audio problem

af4b
I recently noticed a crackling or motor boating  sound on the recorded messages on my KDVR3. Has anyone experienced this problem and how did you correct it?

New happy K3 user

VE3GNO Daniel
 Hello All
Finally I got my K3 SN 6027 in a kit form pretty much top loaded (minus 2m Xverter). It took me aprox 8 hours to assemble (in two days) end to end; very smooth and excellent assemble instructions, crystal clear. Tnx to Elecraft team for all, with over 20 years in R&D wireless I was impressed with quality PCB's, hard to find these days this kind of high end products. Sofware wise I realize the developement effort for optimizations and bug fixing (never ending process).
In the past I had the chance to play with K3 but I never had the chance to go in details with all menus and settings. As a general remark the menu settings are fantastic, far much better than any other trx's, at the beginning I was afraid the appearance won’t reach my expectations having side by side and FT5K but once I turn it on I realized the ergonomics and menu navigation is optimized for contest usage. So far I am happy and start diving deep into advance settings.
 I have a quick question related AGC with MCU 4.47. I have installed FM/2.7/2.1/400/250 filters on both RX's. Any recommendations as start point to AGC settings for contest/DX usage? Any comments are welcome.
