Yes, I programmed my 7550's with CPS 2 and the wideband entitlement at 25 khz. I was forced to use CPS 2, because Motorola does not support wideband entitlement for CPS16. I spent a lot of time searching for the "hex edit". I found two different edits that did not work for me. The hex edit is apparently a super secret that no one will reveal how to actually do it . Everyone just says "do the hex edit", but no one reveals how to actually do it. Apparently it is taboo here on this forum also.
Using CPS 2 is not such a big deal for me. It seems a little slow, but I am not programming multitudes of radios.
I also bought an XPR 4550 that I can't program with CPS 2, in order to do the wideband entitlement. There is some sort of limitation of the code plug. I am putting that radio on the back burner for now, as I just bought an Acom 1000 amplifier for amateur radio, and I will be installing a 240 volt outlet for it, and setting it up in my ham shack. That amplifier is a work of art!
