To paraphrase Paul Bennett N7OCS, 'The Syntor X, Syntor X9000 and Syntor X9000E radios use a 'drop shadowed' X graphic. This drop shadow is cosmetic only and there is no such thing as a Syntor XX, Syntor XX 9000 or Syntor XX 9000E radio. On the other hand, there are Syntor X2 and Syntor X3 trunking radios, so the use of the 'XX' can be confusing and should always be avoided.' Also there is a space before the 'X' and no dash or hyphen between the X and the 9000. In other words, 'Syntor X9000' is correct, 'Syntor X-9000' is incorrect, as is 'Syntor-X9000' and 'Syntor-X-9000'. |
The Syntor line of mobile radios are synthesized 32 channel radios forVHF and UHF. The Syntors were made in the 1980s and were an outgrowth of the crystal controlled MICOR series. The RF frequency information was heldin a one-time programmable PROM chip, and the PL tone / DPL code information in a second chip. Paul Benett's web site listed below provides alternatives to the almost-impossible-to-find PROM chips and the methods to program them. The Mike Blenderman K7IC web site, also listed below, is the fount of knowledge on the entire Syntor / Syntor X / Syntor X9000 series.
The Syntor X radios followed the Syntors and were completely different inside (they really should have had a different product name). They offer more options including low band and 32 channels (or more). The programming is held in a plug-in memory module that holds one of several different sized memory chips. The programming information holds separate receive and transmit frequencies, PL or DPL (tone or digital encode/decode), a timeout timer (programmable in 15 second increments to over 7 minutes) and a scan list (up to 32 channels) with two priority channels. There is a mod that provides 64 channels, but it's not as desirable as you first would think (go read Mike Blenderman's page on it to find out why).
Two sources of Syntor or Syntor X memory module programming are: (offsite links)
You can contact either of these people via the contact information on their web sites.
If anyone else would like to be added to this list just send an email to Mike Morris WA6ILQ at (his-callsign) //at// repeater-builder //dot// com.
Yes, the email address is disguised in an attempt to avoid spambot email address sniffers.
The Syntor X9000 followed the Syntor X and is the same radio from an RF standpoint, but the internal controller board was upgraded to expand the number of memory channels up to 255. The control cable connector on the X9000 is the same as the X, but the accessories are not compatible. The X9000 uses Systems 9000 accessories and options that communicate with the radio via a 9600 baud serial bus. The control head(s) are smart heads with their own microprocessor inside. Unlike the Syntor X the X9000 is programmed with RSS (and a slow PC), a RIB and special adapter cable that goes in series with the normal radio cable. The special cable is not an absolute requirement; there are several ways to make your own connection from a radio to a RIB. In other words, the X9000 is a more desirable mobile radio than a Syntor X since you don't need the almost-impossible-to-find suitcase programmer for the plain Syntor or the Syntor X... you just connect a slow PC or a laptop to the X9000 and program it. The RSS package for the X9000 contains two programs, one to program the radio, and one to program the head (you program the radio with the information (frequency, tone, etc) for each mode, you program the head with the text to display for each mode).
One quirk about the 256 channel X9000 radios: the memory chip in the head only has room for about 209 text labels. When you go to any channel above the limit the display changes and displays the word 'MODE' plus the channel number. The firmware allocates a fixed number of display memory bytes for each label - in other words using fewer characters in modes 1-209 does not move the switchover threshold. I've found that 209 text labels is sufficient for my needs.
The Syntor X9000E models are actually conventional Syntor X9000 radios with an internal trunking controller board added. The 'E' model offers nothing to the non-trunking user and are not any more valuable than a plain X9000. These radios can be easily converted into conventional Syntor X9000 radios (which is not true of trunking Syntor X models).
Note that there are a wide range of Syntor line accessories and that the cable and head are not compatible between the various Syntor, Syntor X Syntor X9000 and Syntor X9000E models. The only accessories that are the same across all radio lines are the speaker, microphone and antenna. If you do not have experience with the Syntor series and decide to buy any Syntor you really need to purchase a complete installation kit - the radio, cable and the head. Mike Blenderman's and Paul Bennett's web sites (linked below) will help sort out the confusion, but it's best NOT to try and mix and match unless you have the full manual that covers your radio(s) and accessories.
Mike Blenderman K7IC has his own very extensive web site on the Syntor, the Syntor X, the Syntor X9000, the Syntor X9000E and the trunking models of the Syntor X and X9000 listed below. There is no point in duplicating his effort here at Repeater-Builder. This web page is only going to cover topics that are not covered at Mike's site. I really suggest that you go to Mike's site first (and bookmark it).
John W1GPO discovered a bad situation dealing with grounds when using SyntorX9000 radios and external power supplies, as in base/repeater installations.
We finally realized why three X9000 radios I recently repaired failed, whereas my personal X9000 radios have never failed over 15 years. Two of the failures happened to X9000 radios used as a base, and one was a mobile, where in this case neither the mounting tray nor the antenna were grounded to the car body (a mag mount antenna was used). None of the failures involved antenna power or SWR circuitry, or a burned out neon bulb coax surge protector, so the problem was not a surge on the antenna. In one radio I had to replace three boards where one component in each went bad (mostly ICs), and in another radio (the hardest to find) a ceramic chip cap on the feed-through wire to ground on the current sense line from the PA became leaky when voltage was applied.
The problem is that the black A- power lead is not grounded to the radio's case, which the coax shield goes to, but half of the interior boards ARE grounded to the coax shield/radio case, and half have a floating ground associated with the black A- lead. Everything is just fine if the radio is installed in a vehicle with the radio tray and antenna shield grounded to the vehicle's body, along with the black A- power lead, as per Motorola's installation guidelines. When an external power supply is used that does not tie A- to the radio case/coax shield, a voltage surge between the antenna and power line ground develops inside the X9000. The radio case/coax shield likewise needs to be connected to A- via vehicle ground or directly to each other in the case of no antenna ground to the vehicle. Note that most Astron power supplies tie the negative lead to chassis (power line) ground.
This situation could affect any radio with a configurable (positive or negative) ground, such as a MICOR.
The Syntor, Syntor X and Syntor x9000 can use 4, 8 or 16 ohm speakers. All use an internal audio output transformer and you don't need to do anything special to do measure quieting, etc. (as opposed to the later Mitreks, MaxTracs, etc that drive both sides of the speaker audio outputs, where you have to use an 8 ohm, 1:1 transformer in line since you can't connect either side of the radio's speaker output to ground).
After Skip Hansen WB6YMH and Lee Dusbabek K7KAJ picked up a fleet of radios that had been sold without the memory modules, they designed, built and now sell a replacement memory module for the Syntor X called the Xcat. It plugs into the Syntor X in place of the original Motorola module and provides complete funtionality plus it is programmable by a PC using a Windows-based program. A Syntor X plus the Xcat is a much more capable base station or remote base radio than an X9000 - and much cheaper! However, if your interest is in a standalone mobile radio then the X9000 is still the way to go as the X9000 came in 32, 64, 128 and 255 modes and offers an 11-character alphanumeric display control head. In contrast, the Xcat provides 32 modes and you can't run some accessories (like a PA-siren) from the Syntor X main control head (when the Syntor X was a current product Moto provided an accessory control box that mounted on top of the radios control head). Click here for a photo of the Xcat boardClick here for a photo of the installed Xcat board. The brown connector at the top of the first photo plugs into the Syntor X in place of the original Motorola module (so if you end up with an eBay Syntor X that was decomissioned by pulling the module you can add the Xcat and turn your doorstop back into a real radio). Again referring to the first photo, the 10-pin header that is visible in the lower left connects to a DB9 connector that plugs into your PCs serial port (COM port) for programming the Xcat. The 20-pin header at the lower right is for a connection to a repeater controller when used in a remote base application (it's the multicolor ribbon cable in the 'installed' photo). The Xcat allows remote selection of RF frequency, PL encode and decode tones, and power level via the Doug Hall 'RBI' protocol that is supported by most controllers (and you don't need the Doug Hall box!). The Icom CI-V protocol or the serial protocol can be used by controllers that don't support the Doug Hall protocol. The Xcat module, when plugged in place of the original Moto memory module, provides:

Syntor X9000 Low Band Radio System 100 watts 31-50 MHz Service Manual 15.6 MB PDF file donated by Eric Lemmon WB6FLY This radio came in ONE range! Despite it saying '31-50 MHz' the radio will do 28-54 MHz just fine - as long as you realize that the average low band mobile antenna only does a 1 MHz portion of that band. The only way to get around the 1 MHz limitation is to either use two mobile antennas (which gives two 1 MHz 'windows') or to use a screwdriver antenna and a self-contained auto-tuner (like an SGC). The details on the two-antenna setup is in the mobile section of the Antenna Systems page at this web site. |

Making your own TRN4224A PL tone plug by Mike Morris WA6ILQ The TRN4224A Tone Plug is used in internal tone PL boards in radios such as the Mitreks, Syntors, Maxar, the Systems-90 multi-PL mobile encoders and some other devices. While this article is Mitrek oriented, the information is valid for any equipment that uses the TRN-4224 series of plug-in tone module. |
Making your own TRN6005 DPL code plug by Mike Morris WA6ILQ from information and photos provided by Jerry Matthews WAØUZI Like the tone plug above this module is used on a wide range of equipment including Mitreks, Syntors and the Systems-90 multi-DPL mobile encoders. A quad DPL board for a MICOR base station is shown in the article, but the information in this article is applicable to any equipment that uses the TRN6005 series of DPL code plugs. |
Improving the performance of the low-band Syntor X9000 by John Haserick W1GPO The stock radio performs well up to 50 MHz, but the output power suffers above that. By modifying the coils in the harmonic filter, performance is extended to cover the full 6-meter band. |
The MCX100 requires a PROM burner for programming and is similar in that respect to the Syntor, whereas the MCX1000 is fully programmable using RVN4011 RSS, like the Spectra.

MCX1000 VHF Service Manual 8.7 MB PDF file donated by Eric Lemmon WB6FLY A note from Eric: The 'Diagnostic Test Plug' is mentioned twice in the manual, once in Section 3.6.2 (Oscillator Frequency Adjustment), and once in Section 3.6.3 (Deviation Adjustment). The Test Plug is Motorola Part #0180358A54 and while it is no longer available you can make your own. It is nothing more than an RJ-45 (8-wire) modular plug that has a jumper between pins 4 and 5. Those are the middle two pins, so it's hard to get it wrong. |

Mostar Information and Programming Source Andy Brinkley of Brinkley Electronics in Winston-Salem, North Carolina (offsite link) While his web site may not specifically say Mostar, he does have the equipment to do them. |
Repeater-Builder is looking for a schematic (even a hand-drawn one that you traced out) of the MIB (Mostar Interface Box); even Moto's own MIB service manual (6880900Z57) doesn't have the schematic. The MIB is different enough from the standard RIB that it can't be used to program a Mostar. |
