[Dstar] D-Star Bandwidth

[Barry Sullivan]

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.
