BPR40 Spacing

Post by vb105 »

Having a bit of an issue programming my BPR40. I can't program frequency 155.8525 into my radio because the software doesn't allow me to program. Is there any mods that can be done to the EXE using a hex editor to allow me to program that freq? Thanks!

155.8525 Mhz is not a valid 25 or 12.5 Khz assignment. .8525 falls 25 Khz above and 10 Khz below the valid assignments or 155.8500, 155.8625, 155.8750. Are you sure you don't really want to program 155.8625(which is evenly divisible by 12.5 Khz)?

The BPR40 will not do 6.25 kHz splits. It is limited to 12.5 kHz splits. 155.8525 is a valid frequency if you have a very late model radio that has been designed to handle such an assignment. An example would be a TRBO or XTS portable.

Tom,

The frequency the OP gave is not evenly divisible by either 6.25 khz or 3.125 khz.
