[Motorola] Syntor X9000 low band programming into the 6 meterham band

[Jim Szalajeski]

The change from a 32 channel radio to more channels requires that the current 2816 EEPROM 
be replaced with a 2864 EEPROM.  I just bought some from Digi Key for something like $4.70 
each.  I don't consider that very expensive.

Also bear in mind that depending on which control head you have on your Syntor X9000, 
you may have to do the same swap out on the control head.  The 1073 head is already 
able to do more than the 32 channels.  If you have the 1033 head, it probably has the 
2 K EEPROM and it will have to have the 2864 to go to the 8 K requirement to go above 
the 32 channels.

Just remember to move the jumper on both the radio and the control head if you do 
the EEPROM upgrade.  In the 1033 control head, the jumper is a surface mount zero 
ohm jumper.  The radio is a pull off jumper like in computers.
