Subject: [Dstar] D-Star Bandwidth

 

Hi,

 

I have a question that some very knowledgeable person may consider answering
for me.

 

That is: "Why do we need to use transceivers with 30KHz band requirements
when I'm told D-Star only needs 2.7 KHz band width." 

 

I reason that if only 2.7 KHz is needed then any attempt to move to that
band width would only need a modulation and limiter adjustment in the Tx but
new receive filters in the Rx.

 

Therefore is there any provision to permit modification of the current
generation of D-Star radios?

 

I think the question is important as there is a current review taking place
of the 400MHz spectrum usage and we may find ourselves very limited in
spectrum allocation in that band.
