Subject: Re: FT-8500 Need Mods From: Mike Obermeier The mod is easy. This will give you 137-174mhz and 410-470mhz Tx/Rx. 1. disconnect power and antenna (like, you would'nt of done it already.) 2. open up the case by removing the screws and gently removing the cover and unpluging the speaker. 3. locate and CUT the GREEN WIRE on the CONTROL BOARD ( the vertical board behind the control panel. 4. reassemble the radio. 5. RESET THE MICROPROCESSOR (so much for the memory!) (press and hold [D/M] & [REV] & [ENT] & turn the power on) (turn off the radio). (press and hold [SCAN] & [HOME] & turn on the radio - extended RX mod).

I have added a line or two in addition to mikes mod for the operators that program there FT 8500 with Computer Software. After doing Mikes Mod the radio will not program VIA ADMS-2 software without doing the added steps I have added.. SEE BELOW __________________________________________________________________________ Mike Thanks for this mod but there was 1 step that I believe should be added as this really made me think this mod was not any good: Subject: Re: FT-8500 Mod Addtions From: Tommie Taylor ADDED BELOW * If reprogramming VIA ADMS-2 Software, you must template from radio to computer before Ft8500 will accept the reprogramming via computer.. If you do not send template from radio the FT8500 will not accept the freq from the computer, This made me believe the mod above didnt work.. Again Thanks Mike for the mod...
