is there a difference between front and rear controlheads. or just cable

There is a difference in the internal code of the control head.

Jason

And... Different button asignments, and the on-off switch is mechanically stopped in the on position.

Some rear heads can be programmend as a normal front head.

thank you gentlemen Happy New year

Will is right, you can swap them back and forth, however that one bit that is changed will once in awhile bug up the radio, requiring a power off/on cycle.

Jason

Can you use bitbanger to make a front one into rear one

No.

Yes. You simply have to know which address to change to what. I have converted a trunking only Spectra head to a conventional X9000 head by bit-banging, as well as converting an X9000 rear head to a front head. Why would you not be able to convert a front to a rear?

The problem isn't within the codeplug. Its the hardcoded control head processor.

Jason

Then how can you possibly change a rear head to a front? I know that works, I've done it.

i have an a9 on a 100watter set up with 2 front control heads one is just programmed as the rear
