Software interface to UDR56K 3 messages
I don't want to rush NW Digital.
But, I would like to get API's to the radio as they become finalized.
This will allow me to start building some software before I get the radio.
Respectfully,

Sorry for the delayed response. I was away from Internet all weekend.
The problem is not desense. The UDR56K is half-duplex so I don't need
to worry about desensing the receiver during transmit. And
