Hi All, Can anyone let me know how to program the COR line on the Motorola GM340 (UHF). I have scan the net and found lots of conflicting info some say pin 4 some say pin 8 and some say 12. As anyone got a codeplug I could have a look at has this may help point me in the right direction or any help in setting up this radio. 73 Rick M6PZT
