spectra A9 controlhead

[kb9rre]

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

[jmr061]

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

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.

[kb9rre]

thank you gentlemen Happy New year

[jmr061]

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.

[kb9rre]

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

[jmr061]

No.

[kf4sqb]

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?

[jmr061]

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

Jason

[kf4sqb]

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
