I think if you change this to the following it will do what you want:

  real_freq /= 1000.0

You need at least one side to be a float to get a float in return. Then
I think that this will work:

> +        val1a = RadioSettingValueFloat(136, 512, real_freq)
> +        val1a.set_callback(my_validate)
> +        rs = RadioSetting("footest", "VFO A Frequency", val1a)
> +        workmode.append(rs)

Since you have to do this twice, I'd like you to make it a helper
function, like this:

def convert_bytes_to_freq(bytes):
    real_freq = 0
    for byte in self._memobj.vfob.freq:
        real_freq = (real_freq * 10) + byte
    return real_freq / 1000.0

Then you can do this:

val1b = RadioSettingValueFloat(136, 512,
                               convert_bytes_to_freq(self._memobj.vfoa.freq))

On the set side, you'll need to do the opposite of the above,
potentially with a special-case for those two values (I forget how that
code is organized). I imagine getting the "get" side working first is
your priority, so we can work on that after you're happy with this.
