Bitbang A4 Control Head?

[kk6rq]

So I find myself needing to change a buddy's Spectra from an A5 to an A4. Unfortunately I can't find my notes from the last time I did it, there are no
existing A4 radios here at the moment and the Batlabs page only mentions A7s and A9s. Anyone remember the byte (@ 6060h)?

Thanks.

ps. I also remember discovering there were 2 different bytes that both worked

Did you check to see if you can just change it in the RSS? The A5 head type can be set to standard or enhanced. If you also have a rotary option, then that is an A4 head.
