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,
Marsh

I see the specs for the UDR56K specify "RF Connector: Type N" but is it male or is it female?

Developers,
I'm trying my hardest to spread the word about the UDR56K-4 here in CT, but many hams have adopted the "proof is in the pudding" theory.
Would it be possible to record and post an actual

Repeater builders use a highpass lowpass combination (procom 70/6 or
similar) to transmit and receive on the same antenna ... now my rough guess

These filters are also available as a single bandpass (with several cavities
in a row) ... so ... would that prevent other transmitter signals from
coming down back in the pa??? (isolator would help .

Hailing channel and intermodulation suppression 3 messages
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
