I posted this in a different Forum but it is good info to have here too.
AT-6666 Pro Mic wiring info:
Totally different than AT-6666 mic wiring
6 pin Mic connector - only 4 wires needed
pin 1 = Audio (White wire stock mic)
pin 2 = N/C
pin 3 = TX (Red wire stock mic)
pin 4 = PF/UP/DN buttons (Blue wire stock mic)
pin 5 = Audio Shield & Circuit ground (Bare copper stock mic)
pin 6 = N/C (no voltage measured RX/TX)
PF Button = pin 4 > 33k resistor >Mom switch > ground
UP Button = pin 4 > 15K 1% resistor > Mom Switch > ground
DN Button = pin 4 > 8.2K resistor > Mom switch > ground
PTT = Pin 3 > Mic Key switch > ground
Pin 3 & 4 (TX & Channels) have a .01uF capacitor to ground
Pin 1 (Audio) has a .47uF capacitor to ground
Qixiang finally got smart and moved the Ch buttons off of the TX line. No more Ch/Freq change when you key/unkey the radio.

I clicked through on Scott's video and saw the other video showing the new shorter N II... and now I'm pissed because I just bought the Q5 N II not that long ago and have been whinging about how it didn't have the programmable weather channel freqs that ARES II has.
I did also notice the huge open space inside when converting it and thought that was a bit of a waste. I get it though, it's the same common chassis size all exports have used since the good old days. But shorter does make sense.
Guess my current N II is for sale now. Wonder if they fixed the custom roger beep programming too...
8 total RB's. 6 preprogramed and 2 Blank. Using the PC software and a programing cable, you can modify any of them. 14 tones per RB, each tone up to 2.55 sec. long for a potential total of 35.7 seconds. That can be repeated 10 times.
For the truly obnoxious, you could conceivably create a 5 minute 57 second long Roger Beep.
Observations:
"ANL" only works in AM mode - even if programmed in PC software for other modes. ANL is very effective on AM.
Clarifier only works in SSB mode.
Clarifier has "Dead Space" - Anywhere between 11:45 and 12:15, the clarifier is center slot; doesn't shift. Past those 2 points,
Freq Display will show a shift in 10Hz increments (Clarifier range set to +/- 500Hz). Very Slick!
With PD = Off, remembers last settings for each Freq./Channel (mode, NB/ANL/HiCut/RxNR/TxNR, etc.
Setup custom scans. Ex. D band ch 1-34 = AM, NB/ANL, Hicut, RxNR, etc. ch35-40 = LSB, NB, Hicut, RxNR, TxNR, etc. When Scanning, settings will change with Ch/freq.
3 AC Fuses??? Pigtail has a 15a 250v AC fuse in positive lead. Power cord has 15a 250v AC fuse in both leads. WTH??? Change to SFE/AGC 20a 32v at least. Do a before and after comparison with INDIC set to "DC" on Full power SSB TX to see the difference in v drop.
eSSB capability
Stock wire is 2.0mm (between 12 & 13 gauge). Upgrade to true 12AWG or even 10AWG (along with fuse upgrade).
Owners Manual says "Menu" when it should be "Func".
I am sure there is more, but this is a start.
