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.
Do you know where C569 is located if so can you take a picture of it? Thanks for the helpI would be happy to provide pictures and the way I tune them up. Email me at email@example.com. The npc\rc modification and tune is similar to the ranger boards. Be forewarned that the proper mod is with a one end 9:14 or 1 in 4148 signal tired and a 100 ohm 2-watt resistor. While the mod can be done with only the diode for a higher yield in average Watts, I have it installed with a competition quad six that I can switch the mod in and out of the circuit.the radio is easily capable of producing pep wattage in excess of 100 Watts. I drive my 2 pill class c with the radio and yield close to 430 w. Pep, at 13.8 v. It makes a perfect driver for a class c-2 pill or idling along a 6 or 8 pill.shoot me that email and I'll try to get a response together sometime tomorrow. Long live CB tricks mirror sites! I hope Benny brings it back or whoever took it over. What a fantastic resource it was for the online manuals service manuals etc. A wealth of information that hopefully others downloaded before its demise.
I am running the SS 9900 version of the 6666 in my pickup, so far not a problem and it's right out of the box.I actually swapped the coax from quad5N2 to the quad 6 today to give it a little spin. It's still a great Dx talking radio many qso on it today, one of the best I've ever owned.
In my opinion after years of use , with the proper tune they cruise right along without any mods.
