Are you "positive" the correct wire was snipped? Only reason I ask,is I did
my 261A and it didn't work. I then went back for some more homework and
discovered the website I got my info from was incorrect! So,I tried the "new" info and I had success. I don't recall the (correct) website now as that has been several years ago.
Good Luck.Slim.

yes

Thanks for answer.

Well i think it was the corect wire,,the green one!..because i did the same in a TM-241 E and it work fine, but the 241 A its diferent bout frequencies, got 118mhz and the E version (europ) don´t. Soo i cuted the same wire i saw in the other. And it open full RX, but TX just at 152mhz!,,about Install an MA141A chip diode in D209 on the Control Board, it´s alredy there from original! that put me confuse. Have any idea ???
..but do you remember what you did in your model ?,,mabe it will be the same!!

This is from ArtSci edition #8A:

For simple MARS mod giving 142-151 MHz simply cut the green wire.

For expanded coverage typically from 138-165 MHz you need to leave D209 installed and REMOVE D206, D207, and D208. reset CPU by holding [MR] and turning power ON. No mention of cutting the green wire for this mod.
