The Radio Information Board

Hi Group...
Anyone happen to have the pinout for the 10-pin programming connector on the bottom of the HHC junction box? Also looking for the mic pinout for the new Lightning remote head.

EFJ holds any technical information for these radios rather tightly...

Also, if anyone needs a 5300/53SL/ES serial programming cable (direct connect, no RPI required, brand new) email me. Special deal for group members.

Thanks!
Andrew

Hi All!
I'm still having no luck finding the 5300 HHC programming adapter pinout (or the pinout of the 10-pin connector on the bottom of the HHC junction box).

Someone must have a manual for these things! EFJ will "neither confirm nor deny..." (as usual)

TIA!

Does this help any?
