Syntor X-9000 system combination confusion

[kgreene]

Hello:

I recently obtained a Syntor X-9000 VHF system combination that was really interesting to me (due to the HHCH). However, as expected, something was a bit weird. I was told the system was removed from a prior government user and what I purchased was all of the items installed in that vehicle. Having tried to bench test it and learning it did not work, I came to this site and started investigating the various parts of the system. From what I see, the system is not a logical collection of the X-9000 series.

The Radio is a T73KXJ7J04BK (seems ok here)
The SIU is a HLN-1170A
The HHCH is a HCN-4027C (securenet, NP Scan, 2 digit display)
The securenet box is a HHN-4014A

The control and power cable is assembled and seems to connect all the various parts. Visually, the impression is that it looks like the radio was uninstalled and put into a box and sold to me. The system is clean (not dirty) and I was hoping it would work well (after new programming).

Having reviewed all the model numbers, I would guess is that the X-9000 is wrong as the various other pieces would be used for a Syntor X and and not a X-9000 trunk unit.

Does this make sense????

Thanks.

The part numbers from the HHCH dual radio manual are here:

The most important thing is each Syntor X 9000 radio drawer has a special part number (HLN5027ASP04 / 01-06710T70) firmware programmed into the U501 chip:

If you open up your radios and look at the U501 part label, each one should have the 01-06710T70 part number on it. You also need the large 28 pin U502 EEPROM. If either radio has the smaller 24 pin U502 EEPROM then it is not configured for dual radio use.

These radios always came in a Securenet configuration with an External Security Housing for each radio drawer. The dual radio HHCH has a custom circuit modification in the microphone circuit and uses a newer design. Your HHCH is from a Syntor X and is an older design that is incompatible with a Syntor X 9000 SIU.

I do not have the part numbers you gave for the SIU and Securenet External Security Housing, so I'm not sure what they are from.

You also need a special RSS to program Syntox X 9000 dual HHCH/SIU radios.

Hi:

Thanks for the information. I had a feeling that it was not going to be easy.

On the bottom of the RF unit, the printed programming data is:

621HNN0619/T73VXJ7J04BK (I assume serial number and model #)

The system was (is) programmed on 166.0000 TX and 166.0000 RX

It seemed to have had the programming to support 64 channels.

The orange programming PROM is a 721HKS0489A1

There is a sticker with the indication of: "HUD 1092C" and a second sticker with a number of "8176" and a third sticker of "MRO#03".

The SIU does not have the means to connect to another RF unit so I thinking that it should be a single band (Syntor X) system and not a dual unit version. The cables for the RT unit, the DES box, and the HHCH were connected to the SIU and were clamped in when I got it. The SIU does NOT have any logic on the card (no active elements). It seems to be more a way to interconnect the three cables (radio, HHCH, and the DES box).

My guess is the actaul X-9000 is fine and the Syntor X accessories are ok. I just need to find the opposite pieces to make it work.

Thanks.

This information means the radio is a Syntor X not a Syntor X9000.

....The Radio is a T73KXJ7J04BK....

The above model is a Syntor X 9000 model number.

...T73VXJ7J04BK....

This model number is a Syntor X model number.

You may have a Frankenstein parts radio with the wrong front label. It iis possible to convert a Syntor X 9000 into a Syntor X. The number on the orange programming prom is the serial number of the radio it originally was programmed for. Orange label memory modules are strictly Syntor X, not Syntor X 9000.

Syntor X:

Syntor X 9000:

If your radio is actually a Syntor X then you probably have the correct single radio SIU setup. The Syntor X does use a SIU for a single radio drawer also. At least the HUD1092C indicates you have the optional Rx preamp.

You can also convert a Syntor X into a Syntor X 9000:

Hi to all:

Thanks for all the answers.

Now I have to make it work. I think I know a place on the East Coast that will program the code plug. I saw an ad for them a long time back and I may find it again.

The challenge is that even with the right voltages applied, the HHCH does not light up and no audio on the receive side. I did check the power connector as there was a comment about a poor design on connector B+ pins (later fixed by Motorola with Epoxy). I used a VOM and did see the +12 VDC as specified in the web page on the three pins.

Time to order the service manual from Morotola. I had the new supplement for the Syntor X some reason.

I wish I could send the radio to a local Service shop (I have far too many projects) but I think that getting any form of support for it is impossible. I will add the Syntor to my list I guess.

Thanks again.
