You're going to be a while on that soap box. CODECs are almost

My biggest problem with the D-Star repeaters is that they didn't make
them analog compatible. Knowing as little as I do about the D-star
hardware, it would seem easy enough for Icom to have done so. All they
would have needed to do would have been to look at the incoming signal,

You mean like the Motorola RF devices and chips used
in many two-way radio products other than Motorola's?

Around here (Western PA) the governments bought Icom D-Star radios for

analog modes with analog repeaters. Now they are wanting to get D-Star

Unless you have a Aeroflex 3920 with the options you can scan DStar as well as
Mototrbo and all others.

I guess it depends on how you want to set it up. As a standalone
repeater it needs no internet connection. if you want to use
connectivity to other systems, you need and internet connection and it
can or not not be behind a firewall depending on your skill and/or
expertise in securing same...
I do not know that it needs to be handled... The day we have enough
D-Star repeaters and users on the air that an out of town DX signal
trips mine I will be tickled to death... not complainBecause JRRL
did not put an equivalent to CTCSS or DSQ in the system does not make it

A very interesting view. I never this before. The opposite.

I have one and am very pleased with it. It is very heavy so it is best on the
bench. The analog functions are fairly straght forward, however, I still have
some questions about the spectrum analyze that seems to be a great feature.

or both!
