TM732.3 I just figured out the elusive "over the air" cloning procedure! It is actually very simple. The wording on the mods sheets which most owners have is very vague and describes buttons that don't really exist. Well.... here is the procedure: 1)turn on radio 2)make sure radio is set on the the frequencies you want the cloning done on; simplex. 3)turn off radio 4)hold down F and SHIFT keys and turn radio ON 5)radio screen should read bel1. 6)turn off radio 7)hold down CALL and SHIFT keys and turn radio back on 8)display should now read CLonE. 9)to initiate cloning process, simply click on the PTT. DTMF signals will automatically be transmitted over the air. Process took about 2 minutes for me. The bottom signal strength meter will tell you how far along you are on the clone. When process is finsihed, display will read "end". NOTE: Slave 732 must have gone through steps 1-8 for it to work. Any more mod info for this great radio would be appreciated! NOTE: My radio is version K2 where the green wire iscut. Might have to be done for over air clone to work. Good Luck and 73-I take no liability for any problems you might experience Joel KD6ANG@N0ARY.#NOCAL.CA.USA.NA. please feel free to put this on the mods list! 73, Joel
