GTX Service Frequencies - Changing them

[Jonathan KC8RYW]

Stock GTX.EXE puts the service frequencies in the 900 SMR band, not where the 33cm repeater split action is.

Need a fix for changing the internal programming points in service mode for putting it right in 33cm 25 mhz split bands?

I think I've figured out where it puts those points in GTX.EXE.

Get out Hex Workshop. Use the base converter. All values are Intel double(64)

They could probably all be changed to a few hundred KHz away from each other, to get the response in tuning as flat as possible across the entire 1 MHz repeater split.

No correcting the checksum is needed on GTX.EXE

That should make tuning a lot more effective.
