[aprssig] X-BEE wireless modules?

I've used Digi International modules and have a couple as a serial link to my D700. It is not the VSC that John Hansen sells to hams, but a Development kit from Digi International.

2.2.6 Analog Outputs
The PWM period is 64μS, and there are 1023 (0x3ff) steps within it. To put that another way, the PWM outputs deliver a square wave at a frequency of about 15.6KHz with a duty cycle that can be varied in 1024 steps between 0% and 100%.
Digi International has some very good reference docs.

I've seen exactly such an example for a single channel using a pot and LED. Of course the "analog" output
is actually pwm.
I think it
was on the Digi web site. Google will probably find it for
you as that's how I stumbled across it.
