Advancing Ham Radio.. different ideas
Reasons to like / dislike D-Star
Here is a thought from a local club member that contacted me about D-Star:The thought occurs to me that D-Star is one future standard and why not purchase a D-Star radio ahead of the roll-out? One issue is that it adds expense and why buy something today that you...
An AMBE open source compatible codec?

And now roughly 30 years later, (just...
