I just got a pair of Secure Saber IIs into my shop, fresh off of surplus.

When the radios are read, they generate a checksum error in the COPE External Personality. The RPF in the radios when they arrived was total hash.

I generated a new RPF and loaded it. All of the menu commands appear fine, but the radio does not receive (squelch audio on monitor, but not on the programmed frequency) Pushing PTT generates two short beeps followed by one continuous beep.

If I read the RPF back in, it appears fine, except for the checksum error, and the fact that the radio information screen shows 0 zones and 0 channels.

Any help would be greatly appreciated. (I already tried the "not for the faint of heart" procedure suggested on the Batlabs Saber page)

Thanks!

Sounds like the radios are in a different bandsplit than you programmed them to. If they're government surplus radios, they're usually in the 403-433 split. Try creating a new radio file in that split, load it in, and see what happens.

Or, you can open the radios up and see what the module part numbers are. If the last number in the model number is 1 (example NLE8641A) then it's low split. ramge 1, 403-433. If it's a 2, it's range 2, 440-470. And so on.

If the modules all start with NLE they're UHF, and if they start with NLD they're VHF.

They radios are, in fact, VHF. The module number is NLD8180A, so it looks like a VHF low split. What exactly is the lower VHF frequency split?

I think I've tried most of the options under create a RPF at this point.

In the mean time, I beat the checksum problem by turning off my K6 233 and digging out my trusty old 486 / 33 Notebook.

It looks like the short beep on PTT before the continuos tone was MDC sidetone
