Quite often what happens is that the model number gets corrupted during write and the RSS no longer recognizes the radio. Then, open the codeplug in a HEX editor and take a look at it.
The first thing you can try and do is get the codeplug out and save it to disk (use the F6 menu to save the archive). You need to use the F4 Read/Write Radio with No Pack/Unpack option to get the corrupted codeplug out of the radio. You will not be able to unpack the codeplug when reading it, of course, but you can read/write to the radio fine. You will need to use MTSX Lab or Astro Lab RSS in order to do it, both will work fine. It may be possible to bring a GM/GP900 which has a corrupted codeplug in it back to life. It has been rectified on the later models after 1999. The common failure is the 01/90 fail code or the radio is just plain dead. This clamp puts to much pressure on the solder joint. Also, cut the middle finger off the metal clamp that presses down on it.
Where the metal fingers clamp down the board you need to reflow the solder to this regulator if it has not already come undone. It should be U500 and its next to the audio IC. I talked to the local Motorola dealer and they said that programming these radios with older RSS than they had last been programmed with would indeed corrupt the codeplug".Īre you having a problem with the control heads on your MCS2000? There is a bulletin out the 5 volt regulator is falling off of the board in the radio (not the head). It corrupted the codeplug and this brand new radio had to be sent back to the big M.
GM900/MC900/GM1100/GM1200/GM2000/MCX1200/MCS2000/MCX2000/MC2100 GM900/MC900/GM1100/GM1200/GM2000/ MCX1200/MCS2000/MCX2000/MC2100Īll of these radios belong to the same family and are covered under the same service manual, hence, most of the information should be common to all models.īEWARE: Take note of the following we received, "It seems after attempting to write the codeplug of a NEW MCS2000, I got a fail message on the screen.
