Astro Spectra Control Head

[biglogdog]

Are the spectra and astro spectra control heads interchangeable or will I have to have an astro control head with an astro spectra radio? Thanks.

They are NOT interchangeable. They only look like they are.

Yeah, that is what I figured... Well I've got one more question while were still on the subject. I'm looking at two control heads on eBay that I'm sure will both work. The first is HLN6432D (]Motorola Astro Radio Rear Control Head HLN6432D NEW | eBay ) which comes with the housing and HRN6014H (Motorola Astro Radio Rear Control Head Face Plate HRN6014H New | eBay) which doesn't come with the housing. The model number of the radio is D04UJH9PW9AN and has been converted to a remote mount. Any input would be greatly appreciated.

Unless I'm misunderstanding what you are proposing here, there's a problem. First, you need a front control head if you don't already have a good one, not a rear control head, and the radio model number indicates a W9 head. The eBay items are W7 rear control head items.

Sorry guys, I didn't realize that the model was a W9 head. I had bought this radio off eBay (MOTOROLA ASTRO T99DX+133W_ASTRO D04UJH9PW9AN T99DX 133W GREAT UNIT JUST PULLED | eBay) and was trying to get it together. I've got the power and control cables already I just need to figure out what kind of control head I need. Maybe I should have asked that from the beginning. Thanks for all the responses.

How to use those old Spectra Control Heads

Had an Astro W9 control head die the other day. A resistor on the board burnt out causing the HV section to cease powering the fluorescent display. Rather than have a patrol down until the shop could make the board repair or get a new one from the big "M" we took a stab in the dark. Took one of our old Spectra 1073D control heads and plugged it in. It powered up with "MODE 0" on the display but no functionality. On a whim we cracked it open to see what may be different. The ONLY difference was the firmware chip version. We took the firmware chip (sorry didn't write down numbers.... :O) from the bad Astro Spectra head and put it in the old Spectra A9 head. Plugged that sucker in and lo and behold it thinks its an Astro W9 now. So folks, don't throw out your old Spectra stuff as it may come in handy years later.
