Move to better 1-bit DAC

Hi Mark,

what dou you think about switch to a better 1-bit DAC for generating tone?
1-bit DAC requires just ONE resistor and ONE capacitor!
1-bit DAC has a better sinewave form.

I think move to 1-bit DAC is a really good option for your microAPRS modem.
It uses less parts (more easy to handle and save some cost for parts), less space on PCB and has a really better sinewave!

Please take a look at:

and

Hope you will take a look on this!

Thank you
