Help with Control Head HLN 6432C

[kb4vwa]

I just purchased some Spectra Controlheads HLN6432C and they do not power-up for me on my working Spectras. My working Spectras use the HLN 6283B. Is there some jumper that make these units work? Can someone PLEASE help me out, I am out of lots of money a second time buying these control heads and not able to get them to power up. Any help would be MUCH appreciated!!!!

Thanks

UPDATE: The correct control heads I am having trouble powering-up with my VHF Spectra High & Low power are the following HLN6337D & HLN6075D.

I was curious if I read a working radio and replace not working control head and program codeplug back into the radio, will the bad control head accept programming? Not sure if my problem is programming, or jumper?

Any help would be appreciated!

Thanks

What interconnect board are you using to connect the control head to the radio? The newer 6337 head requires the HLN6285 board, or the older board needs to be modified. GARY N4KVE

Correct, check your interface circuit board as some changes were made, hence the different model number, to work with the later series control heads.
