ok I'm at it again .. I just recieved a vhf spectra model TA9GX+078W
ID #T83GXA7HA9AK IT IS ONE OF THOSE SECURE NET SECRET SQUIRRREL RADIOS complete with the encription modules, a secure net boxes and a handheld remote head , the head # is S9000e according to the software is that the # for the handheld head ?
also while reading the codeplug the rss will not let me change head types or even access the button configuration screen . It says not avail for this model pls refer to catalog sheet. Obviously this is a special configured radio but the id # says A9 so will a a9 head work also ? what hardware will have to be changed to make this radio accept a A9 or a systems 9000 head ? Please educate this spectra novice , but this is how i'm learning alot . the id # is why i bought this one, thanks for all the help !!

That model radio is typically part of a dual radio HHCH configuration. The SIU box translates the Sys9000 interface to the HHCH. As long as you keep it in that configuration, I don't think you will have any problems. But I also don't think anything about the HHCH is programmable, hence why you are getting the "not available for this model" section. I suggest reading

You can actually convert it to a regular A9 head radio by bitbanging it. The A3 HHCH radios are A9 radios with a special codeplug programmed. Like previously stated, they talk to the SIU box which translates things to the A3 format that the HHCH can understand.
I have sucessfully changed one from an A3 to an A9 and back again for testing purposes after fouling up the programming when I fogot to remove the 2nd deck while writing to it.
The problem is that it has been so long since I've done it that it wouldn't come as second nature enough for me to assist you with a step by step list.
The problem I had came from both drawers being connected when writing to one. It caused a foul up that ended up putting bad mismatched data in the command and mlm boards. If they don't match you get an error and it won't operate. I changed both locations with the proper serial number information then programmed in the A9 codeplug and it worked.
Be sure to save the codeplug from the A3 configuration first and make sure you only work with one drawer attached to the system at a time.

The problem with the A9 dual radio drawer is just the code plug. This is not an A3 setup. The A3 radio drawer has a special Interconnect Board, special MLM, different command board jumper settings and does not use the SIU. The HHCH/SIU version of the A9 dual radio drawers have the normal A9 Interconnect Board, normal MLM and normal command board jumper settings.
The main problem with the code plug is the limited two digit numeric display on the HHCH. The code plug is not setup for an A9 eleven character alphanumeric display and the RSS blocks options that the HHCH is not setup to perform. Another common problem is HHCH/SIU radios that have lost their Securenet boxes and will only give an RSS error until the Securenet hardware is restored (you cannot read or write the radio). If you want to remove the Securenet hardware, disable it in the RSS first, before you remove the hardware.
Bitbanging or replacing the code plug with one from a similar Spectra (same power level, band split, etc.) should get the drawers working in a single radio drawer A9 configuration.

thank you !! very informative !! I have the encryption boxes and have disabled the securenet . now.. I have a saved codeplug which I think will work . Now I need to hear some feedback and instruction for subbing the differant codeplug , like how do you trick the rss into taking the differant s/n codeplug any help would be appreciated as all before this is !!
