Nothing like the proper gear you guys have, but have been able to do frequency adjustments by viewing signals on an RTL-SDR band scope. Have used a nanoVNA as a signal source before, and have heard of using a sound card as a signal source to produce different wave forms but haven't gotten that...

Found another radio: " CRT 7900 " that has a very simliar engineering mode hidden menu like the Lincoln II+ does.

Next trick is figuring out why the mysterious Lincoln II+ has poor audio on strong local SSB signals. It sounds great on distant stations. Before that one guy always chimes in with the obvious, about turning down the gain, that ain't it. There is an adjuster, W6 on the board labeled...

Test your antenna just because. Maybe a neighbor's cable coax was damaged or removed and not terminated. Lots of rats' nests in that kind of system.

My Kenwood TM-261 starting acting up in my usual high power transmit mode last night. I could hear static come from the speaker while transmitting, and it sounded like a digital mode signal to those who heard me transmit. I lowered the power to medium and low, and the problem seems gone, but...

Sorry, I adjusted BFO for USB. I just wrote the wrong mode in the post. I'm with you on that. So I checked the other modes, and they seemed spot on. When I monitor regular AM with an RTL-SDR, I see carriers drifted all over the place, but the guys still sound good. Seems most critical in...

Wonder how well a folding whip would work like on those old military radios. One could be fabricated from measuring tape and green paint. Don't know if this one works but it has a loading coil. I also wonder if an external mic would work as a counterpoise.

Adjusted Upper side band frequency with the engineering menu last night. Report said my signal was 50 hz low. Lowered the value of FM mode in menu 6 by from 823 to 813, and it raised my signal by 50 hz. Got good signal reports Ohio to New York after that and was able to turn off my clarifier.

Are you running a lightning protector to ground at building entry? I put my common mode filter box (small one) at my lighting protector which is screwed to a ground rod. Band scope looked like a roller coaster before I installed the filter on my WFHW. SWR stayed same across my bands.

Is having baluns installed at different distances, like actually using two antennas connected in series? (My brain is going to hurt before this is over.)

personal notes... I'm just a hack so don't burn up your rig based on my notes. My Lincoln II+ (not for other models, or versions, or yours) DO NOT PRESS "BAND" BUTTON, IT WILL BURN CURRENT Rx SIGNAL LEVEL TO MEMORY!!" DO NOT PERFORM ANY MODIFICATIONS...

Changing my ASC from 437 to 756 resolved AM choppy dead squelch issue. menu item/display/value 12 27.405 ASCon 80 13 27.405 ASCoFF 121 14 27.405 ASC 756**(at 437,had choppy dead squelch in AM, side band was okay)

I don't recommend anybody try changing these, but I had exhausted all proper efforts so had nothing to lose. I'll try to post a list of them. I think they should vary from rig to rig. Initially fiddled with what looked like squelch settings for Db1,3,5,7,9,12 but they made no difference in...

ASC was set wrong in the engineering menu. No choppy squelch any more. Get static like I should until squelch is raised to to like 3 or 4. Two trips to support and they could not or would not figure it out and resolve it or even give me documentation about the menus to help me out. Not much...

Gain definitely does affect what's fed to squelch, for sure. There are several settings as well in the engineering menus the company will provide no information about. This information would be very helpful.

Are you talking about the sensors on the brakes for the ABS, or the speed sensor on the back of the transmission?

Lots of parts on the Lincoln II+ schematic are labeled NC and show no value in the parts list. Are they just saving money? Looks like they omitted a transistor, resistor and cap from a feedback circuit to the main audio power op amp. AM squelch is junk on mine. Everything else is pretty...

Got the radio back. AM squelch is still crap. Have to set it to zero all the time. Maybe the engineer's need to get out of the lab once in a while and explore the real world. At the Cincinnati machine shop, the engineer's offices were on the 2nd story of the machine shop. The boss came in...

Looks like a short candle inside a tin can to me. I mean that signal is going to bounce around between the cowling and the trailer, cancel a lot of itself out, and what's signal that's left is going to go straight up towards another galaxy. I have been wrong before but it was a misteak.

Was on a 2 meter discussion net recently where they all believed and professed that a J pole antenna is truly omnidirectional. This was about one fella having trouble talking to a far station that everybody else could talk to fine. However I think a Jay pole has 1 or 2 small deep nulls because...
