As you have both, I would run each for a couple weeks and see how they do.
The George has more features than the Lincoln, 18 memory channels that remember what mode they are set on when you program them, dual color display.
I do not care for the built in echo, they can be set for several channels schemes ...I think to get the UK FM frequencies spot on, you need to unlock the RIT.
The security code thing could be a pain if you did not know the default, i think you have to apply power the radio, press "program" 4 times and then power the radio on.....do not know if they did away with that on the later models.
The Lincoln is more compact, the George is more the size of the "DX" style radios.
They both were expensive rigs at the time ( over here anyway)
I would treat both with care as it is hard to find parts for them, the Lincoln will have a Mrf 477, Mrf 497 or a Mrf 455 depending on when it was made, and now the transistors are no longer made.
The George has dual 2sc1969`s in it, also no longer made.
If the LCD displays start to "seep" there are no replacements now days.
All of this may sound frighting but it is just age, if they have been stored away in a temp controlled environment it helps.
I have run the Lincoln/2510/2600 all good radios, but they are getting old and are starting to show there age, caps get dry, the glue used to hold components down on the CPU board and a few other places gets dry, old and can eat away at traces on the board.
If you have the latest one that was made with the 455 final, you are that much ahead of the game as far as age.
If you really like the radios, it might be good to think about having a good radio guy go through them and replace the electrolytic caps with new, and clean the old glue off the boards at some point to keep them living.
They are good radios, just that 1988 when they came out with that design was a few days ago.
For More info on the George Maybe Jazzsinger, or Bob85 might have something to say as I am sure they have seen more of that model.
Above all, welcome back to the Hobby and have fun.
