SynPromW32 FREE DEMO -

This software is a Windows program that you can use to generate the Intel HEX files needed to program the Frequency and PL PROMs, EPROMs, etc.

for use in the Motorola VHF and UHF Syntor® radios.
Main features:
-Uses PROM data files which contain your frequency lists, PL tone lists, and also important information about your radio. These files can be Opened, Edited, and Saved using this program.
-Important details about your radio (its frequency RANGE ("SPLIT"), HI or LO side injection,VCO Offset, Number of Channel Banks, type of bank switch, etc.) are included in the PROM data files and can be easily edited also.
-Exports its frequency and PL tone lists to text files for printout, further editing, etc.
-Allows you to select whether the VCO is programmed on the high or low side of the receive frequency (i.e. "high side" or "low side" injection). This feature makes it easy program PROMs for normal radios (ones used in their normal "splits") and also radios used outside their normal splits.
-Generates the PROM data from the frequency lists and vital radio information, and writes the results to an Intel HEX file suitable for use with most PROM / EPROM programmers.
