Got it, thanks @Dr_DX.
How did you determine this? Are you saying it 1kc off what the display says? my 8 digit frequency counter and i also own 11 other radios and another 6666 this 6666 is low on lsb and i can not find a service manual for it my other 6666 is dead on as are my other radioswww.worldwidedx.com
So went through it all, that mod pix, was inserted in a discussion in those few posts in the thread about modulation. I haven't tried to translate the text notes on the pix. Just the post text. Went through the translation (Thanks google) on all the other pages. Nothing about alignment or documents. Near the end someone had the same question about the service menu and the defual settings , as the post someone linked to in an earlier post here just recently.The document from Dr_DX is titled "HAM MobileCom 1011". Might be more clues in that direction. I found a modification for SSB something?
That's exactly what I got out of that one mod.. yes... There were earlier posts w/ complaints about the squelch performance. I thought there was another set of posts complaining about modulation. I might have confused that pix with a fix for that.D'OH!
After a little more reading (slowly), this mod just turns off the auto squelch in SSB. That's it, that's all it does.
