I've just recently started using phone on my K2/100 (s/n 6550) and I've noticed that even at an SSbA setting of 1, I'm getting a lot of ALC (3-7 bars when I talk in what I believe to be a normal voice). I'm using an Elecraft MH-2 mic. I checked the wiring for the mic last night and I believe it is correct. I also notice that the problem is worse on lower bands than on higher bands. I've been operating the radio at about 80 watts on phone.
That's consistent with my experience in digital modes, where I have to turn the output of my computer down to around 20% and keep the TX control of my Signalink turned down to around 2/10ths (the 9 o'clock position). I have checked the jumper settings in my Signalink to make sure I'm not using the special jumper for increased gain on Tx. I operate the radio at 30 watts on digital modes. The KSB2 manual says that the value of R15 can be changed to increase the attenuation on SSbA. What kind of values should I be thinking of? Are there any other adjustments I can/should make to improve the situation? I caught some comment in a post a few years ago about there being an issue with the KSB2 on lower bands and mention of their being a fix, but I'm not sure what to search for in the archives (or rather, the terms I was searching for didn't give me anything that seemed relevant).
