The old lincoln II+ also has receive audio on the mic socket, no volume adjustment in the menu but it works with the uniden bearcat wireless mic.Note that PIN 2 "EXT.AF" is RX audio available on the front mic socket - this is selectable in the "VOL.PATH" menu.
This allows for a single cable connection to the radio for things like a full TX/RX headset, wireless/bluetooth accessory, or a data interface for digital modes (FT8, SSTV, VARA, etc)

Oh man, I was just talking about upgrading my Lincoln II+ V4 and here it is.And here's the clone!

That is not a valid test. It must be equal in every way.I experimented some more today the receive is definitely better on the q6 pro vs the N2. I had both NRC on 3 I did experiment changing them the q6 pro did a better job at filtering out the background noise. Later in the evening the bad seemed dead I was receiving a weak signal on 38LSB w/ q6pro I could understand them, but not on the N2. Test was not exactly equal, q6 pro w/ browning BR140 lower in driveway close to house , N2 top of driveway with Sirio P2000. Both are mobile rigs w/ roof mount antenna. P2000 base is about 5' higher than base of Br140. Q6pro had a big disadvantage but had better receive.
I should have noted not a valid test just observation. I do not own the right test equipment to do a valid test. A comparison with the same antenna would better I may do that in the future.That is not a valid test. It must be equal in every way.
For me the test is valid: the 6666Pro, despite being disadvantaged, has surpassed another RTX and that's enough for me. After all, the 6666Pro being the top model, it's also normal that it surpasses its competitors positioned lower in terms of cost and features.I should have noted not a valid test just observation.

It is not a valid test, when the setups are not the same. The antennas and locations were not the same. That is the minimum criteria.For me the test is valid: the 6666Pro, despite being disadvantaged, has surpassed another RTX and that's enough for me.

Thanks jr26!
All the minimal consistent tests you want but a model declared superior by the company that builds them both will almost certainly surpass the inferior model.It is not a valid test, when the setups are not the same. The antennas and locations were not the same. That is the minimum criteria.
Update.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 >PF switch > ground
UP Button = pin 4 > 15K 1% resistor > UP Switch > ground
DN Button = pin 4 > 8.2K resistor > DN 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.
