I recently purchased an EF Johnson 5100 UHF-low radio that was advertised to have the following features:
Firmware Version 4.14.5 (Latest)
Uses PCC 2.10.2
Conventional Mobile Data, Trunking Mobile Data, P25 Digital Conventional, P25 Digital SMARTNET/SmartZone, Encryption (DES, DES-XL, P25 AES and P25 DES OFB), OTAR Conventional, OTAR P25 Trunking, STAR Trunking, SMARTNET Trunking, SmartZone Trunking, P25 Trunking, Multinet Trunking, Full Keypad Support, Ultra Rare FPP/Keypad Programming, MDC 1200, and 512 talkgroups/channels.
3600 Baud Trunking
9600 Baud Trunking
The problem that I am having is after I program a conventional channel, the PTT button does not allow me to transmit (no matter which channel I program a frequency in, analog or P25 mode) at all. The radio appears in about new condition, so I suspect abuse is not a factor. I do not have any programming cables or software to check further, so is it simply a programming issue somewhere, or did I buy a radio that is as good as a paperweight? Any insight is much appreciated.
