Locating radio model numbers:

Please see the locating radio model numbers instructions on the home page.

Locating radio unified chassis numbers:

The Unified Chassis Number is typically printed on a small white label stuck on the bottom of the radio's chassis (photo). Occasionally this number will be stamped in black ink on the edge of the radio's chassis instead of being on a white label (photo). To locate this label remove the mounting tray, turn the radio over and look on the bottom near the J1 connector. Often the label is obscured by the radio's bottom cover (held on by 4 screws) and this cover must be removed to see it. Unfortunately these labels are missing allot of the time. If you can not locate the Unified Chassis Number label, one way to determine the radio's options, frequency coverage, etc., is to get the manual out, open up the radio and lookup the appropriate subassembly numbers for the radio's internal parts. Another way is the top lid that opens via the pushbutton located under the handle, has the radio factory programming label that may help decipher the frequency range and squelch options (option W12 indicates a VHF or UHF receiver preamp). Make sure the serial number on the radio matches the one printed on the label before using the label information.

Please check out the Syntor X visual tour for photographs of the Unified Chassis Number.

Decoding radio model and unified chassis numbers:

The Model numbers can end in letters AK, BK, CK, etc. and Unified Chassis numbers can end with letters A, B, C, etc. depending on the manufacturing revision of the chassis. These have no effect on the information presented below. Sometimes the letter B is mistaken for the number 8.

There are special order radios that have model numbers which end with the letters "SP" and two digits. Usually the radio will have some custom feature, like a 60 watt low band radio with the "SPxx" suffix. I have also seen radios with combinations of parts that are not covered in any manual, but do not use the "SPxx" suffix like I would have expected. Occasionally you will find a radio that will not do everything you expect or want (i.e. a Syntor X 9000 T34KEJ7J04AKSP99 has no transmitter circuitry at all). Sometimes you just have to figure it out.

Notes:

All conventional Syntor X radios are capable of 32 mode operation with the correct cable, control head and programming regardless of the number of modes indicated by the radio model number. The radio model number indicates the cable, control head and programming configuration the radio was originally shipped with. See here for 64 mode Syntor X programming.

Only factory radio models with "T _ _ VXJ" have the HLN5008A DVP Interface Board, HLN4270A, HLN4270B or HLN4425A DVP Interface Board to support DVP. Radio models with "T _ _ VBJ" are missing the Interface Board and do not support DVP. The actual encrypted DVP audio is generated externally and hooked up to the Syntor X radio.

There are "VBJ" radios out there that do have a HLN5008A, HLN4270A, HLN4270B or HLN4425A Interface Board (they should be marked as "VXJ" models). These appear to be non-factory or dealer conversions. You should check the Personality Board to see if the HLN5008A, HLN4270A, HLN4270B or HLN4425A Interface Board is in you radio or not. Use the Personality Board jumper locator drawings from the jumper page to locate the HLN5008A. The HLN4270A, HLN4270B or HLN4425A is mounted upside down over the Personality Board near the big heat sink in back. If any of them are present, treat the radio as a "VXJ" model.

Any Syntor X radio operated outside its factory frequency range will probably benefit from retuning the receiver front end (depending on how far it is from the factory frequencies). Some radio's may have to have their Voltage Controlled Oscillator (VCO) retuned if the synthesizer can not lock on the desired frequencies.
