A Quick and Dirty Syntor X to Syntor X 9000 Conversion:

Minimum materials required:

Recommended materials:

It is recommended that you check the Syntor X radio for correct operation before you try and convert it. The Syntor X 9000 Personality Board should also be checked before it is removed. Make any needed repairs before attempting any conversions. If your converted radio does not work and you have not previously checked the radios, it will make trouble shooting and repair a much bigger job.

Start with a Syntor X 9000 HLN4295 or HLN5299 Personality Board from a Conventional Syntor X 9000 or a trunking Syntor X 9000E. If you use a trunking X 9000E Personality Board make sure to convert it to a conventional Syntor X 9000 Personality Board first. Next you will need a conventional Syntor X radio. If possible, save yourself grief by making sure the Syntor X radio and Syntor X 9000 Personality Board are in working condition. It does not matter if the Syntor X and Syntor X 9000 radio the Personality Board came from are on different bands.

The 800 MHz trunking Syntor X 9000 radio uses a HNL4920 Personality Board that can not be used for this conversion.

Remember to use anti-static protection when handling or storing any boards or components.

Start with the Syntor X and remove the Syntor X radio Personality Board (unplug the J401 ribbon cable connector first). Desolder the ribbon cable connector from the Syntor X Common Circuits Board and remove the cable.

Remove the Syntor X 9000 Personality Board (unplug the P300 connector from the Common Circuits Board first) and jumper it to match the band of the Syntor X radio. Also set the other jumpers for your configuration. You will need a P300 connector and cable for the conversion. You can get new parts from Motorola or you can salvage the existing connector. If you salvage the connector you can desolder and remove individual wires from the Common Circuits Board. It is crude, but you can also cut the wires at the Common Circuits Board connector rather than desoldering them. The result is you get a connector and cable that fits on the Syntor X 9000 Personality Board and can be wired to the Syntor X Common Circuits Board.

Now place the Syntor X 9000 Personality Board in the Syntor X radio. Finally connect the P300 cable ends to the Syntor X Common Circuits Board as indicated in the Syntor X 9000 Personality Board Pin Out table below. Remember to also connect the pins indicated in the Syntor X Common Circuits Board Pin Out below. Change the "Syntor X" radio label to "Syntor X 9000" so you will know to attach to correct Syntor X 9000 cable and accessories.

Finally, use an ohm meter to verify all your P300 cable connections (be sure to also check for shorts to other adjacent pins). If you make a mistake and you do not catch it and correct it, you could possibly permanently fry your Syntor X 9000 Personality Board and possibly damage the Syntor X Common Circuits Board as well. Most Syntor X Common Circuits Boards have pin numbers printed on the board, if yours does not, then use the schematic and PC board layout from the Syntor X manual and make certain you figure out which pin number is which. The first and last P300 pin number is shown on the Personality Board jumper locator drawings.

As explained below this Syntor X 9000 conversion radio will forget the user settings whenever the radio is turned off. When it is turned on it will revert to the programmed RSS default settings.

Remember, the Deviation and Compensation controls on the Personality Board were set for the radio the Syntor X 9000 Personality Board originally came from and must be adjusted again. The Squelch Threshold control may or may not also need adjustment. Ignore the now defunct Deviation and Compensation controls on the Common Circuits Board.

The Real Syntor X to Syntor X 9000 Conversion:

Minimum materials required:

Recommended materials:

It is recommended that you check the Syntor X radio and Syntor X 9000 radio for correct operation before you try and convert it. Make any needed repairs before attempting any conversions. If your converted radios do not work and you have not previously checked them, it will make trouble shooting and repair a much bigger job.

Start with a Syntor X 9000 HLN4295 or HLN5299 Personality Board from a Conventional Syntor X 9000 or a trunking Syntor X 9000E. If you use a trunking X 9000E Personality Board make sure to convert it to a conventional Syntor X 9000 Personality Board first. Next you will need a conventional Syntor X radio and a Syntor X 9000 Common Circuits Board for the same band as the Syntor X radio. UHF radios have some component differences on low power and high power Common Circuits Boards. If possible, save yourself grief by making sure the Syntor X radio, Syntor X 9000 Personality Board and Syntor X 9000 Common Circuits Board are in working condition. It does not matter if the Syntor X and Syntor X 9000 radio the Personality Board came from are on different bands.

The 800 MHz trunking Syntor X 9000 radio uses a HNL4920 Personality Board that can not be used for this conversion.

Remember to use anti-static protection when handling or storing any boards or components.

Start with the Syntor X, remove the Syntor X radio Personality Board (unplug the J401 ribbon cable connector first) and the Syntor X Common Circuits Board (unplug all cables first).

Remove the Syntor X 9000 Personality Board (unplug the P300 connector from the Common Circuits Board first) and jumper it to match the band of the Syntor X radio. Also set the other jumpers for your configuration.

Now place the Syntor X 9000 Personality Board in the Syntor X radio and install the Syntor X 9000 Common Circuits Board in the Syntor X radio. Reattach the cables to the Common Circuits Board and attach P300 to the Personality Board. Change the "Syntor X" radio label to "Syntor X 9000" so you will know to attach to correct Syntor X 9000 cable and accessories.

Remember, the Deviation and Compensation controls on the Personality Board were set for the radio the Syntor X 9000 Personality Board originally came from and must be adjusted again. The Squelch Threshold control may or may not also need adjustment. The Common Circuits Board Current Limit control and power control will also need adjusting because it was also adjusted for another radio.

This Syntor X 9000 conversion will remember user settings when the radio is turned off.

You now have a leftover Syntor X Personality Board and Common Circuits Board. You can use these as spare parts or you can even convert a Syntor X 9000 radio into a Syntor X radio (the Common Circuits Board must match the Syntor X 9000 radio frequency range - UHF radios have some power related component differences.).

Remember to relabel any converted radio to help prevent plugging the wrong cable and accessories into the radio.

This type of conversion is very easy. It is useful if you have a high power Syntor X and a low power Syntor X 9000 on the same band (i.e. frequency range). You can create a low power Syntor X conversion (the Syntor X parts go in this radio) and a high power Syntor X 9000 conversion without the problems usually associated with locating a Syntor X 9000 Common Circuits Board.

 

Low Band Radio Conversions:

When converting a low band radio be careful of the wires from the Common Circuits Board that are routed under the low band Tx Buffer Board. These wires have never had to deal with the Syntor X 9000 Personality Board hybrids that stand straight up underneath the Tx Buffer. Also the coax feed line into the low band Tx Buffer Board can be a problem. These wires can be bent, pinched or put pressure on the hybrids. I recommend really loosening the 5 Tx Buffer Board screws when installing a Syntor X 9000 Personality Board into a low band Syntor X chassis for the first time (be careful not to loose the star washer on the ground screw).

The low band seems to be picky about the compensation adjustment, much more than the VHF, UHF or 800 MHz radios. The low band does use a unique reference modulation circuit not found in the other radios. The compensation adjustment instructions are in the front part of the low band manual under the "Maintenance and Troubleshooting" section and is really easy to do after you find R628 hiding near a corner of the RF board. The problem I ran into was I could not adjust the deviation on one radio above 4.6 KHz until after I did the Compensation adjustment (the deviation pot was at maximum). After the compensation adjustment I had to turn the deviation adjustment down to get it below 5 KHz deviation.

As with all the above Syntor X into Syntor X 9000 conversions, you will have to do a little rerouting (i.e. physical manipulation) of the wires from the Common Circuits Board to allow the large metal shield to be installed.
