The Syntor X is a completely different radio from the Syntor, sharing similiar basic synthesizer technology and accessories but none of the circuitry or hardware.
- Radios are are available in -
- VHF low band - highly prized as they cover 10M AND 6M in the same breath. (Diamond has a 10M/6M/2M mobile antenna.) Current price is about $200. This doesn't mean you won't see someone advertising one for $375 but (hold my tongue)
- VHF high band - everyone could put one of these to good use even as a base station. Current prices $50-$120.
- 450-470 UHF - ditto above radio. Exception - you will find 403-430 MHz range I radios around but they don't shift to the ham bands without surgery on the VCO (see Syntor info) and retuning (major headache)
- 800 MHz - Syntor X are conventional, Syntor X2 are conventional and trunking, Syntor X3 are trunking. Memory Modules and personality boards are different from other Syntor X's. They can be had cheap! I recently bought a pile of 7 for $5 and sold off the X2 and X3's for $2. It is nice to double your money.
- General info about the Syntor X (800's excepted):
- They have very wide bandwidth front ends but are not easily tuned. The VCO's may be modified to change range and radios retuned but it is best to stick to radios which are close to the frequencies desired.
- Programming is most easily done by removing the prom from the Memory Module. The eeprom in orange label module is a 28C16 but 2716 eproms may be used in those and white label modules (early bipolar type). Inexpensive eprom programmers abound. Check Nuts and Volts magazine ads for new ones under $49. They show up at hamfests for $20, and free from friends (got one free last night). ASK AROUND before paying for one! See me about software.
- The Memory Module holds:
- frequency receive and transmit
- reference and VCO sub-range data
- turn-off-timer (TOT) 15 second increments to 7:45
- scan list radio may scan all 32 channels
- Two priority channels
- pl encode/decode ctcss and digital codes
- The Syntor X cable has a different radio connector than Syntor and Micors. The sys90 control heads are similiar but slightly different. The 12 frequency lines are bidirectional so sys90 head isolation of these lines is required.
- Speakers are 8 ohm, the same as Syntor/Micor.
- Microphones are the same as Syntor/Micor/MCX-100.
