I don't think you will be able to just plug binary data into a radio
transmitter unless there is a made for the purpose FSK input for binary data
that would support the DSTAR data rate. Steve

You'll have to check with AOR on that one. For all we know whatever contract
they may have with DVSI may be specific to the modem. I figured two years ago
when they introduced the AR-ONE that they would include some decoders, or an
expansion port for an option card, or maybe even trunking but no

There's one reason- they would have to purchase rights to the voice decoder
designs from DVSI. D-Star is still young so other manufacturers may eventually
jump on board once they convince themselves that the upfront engineering and
intellectual costs will be worthwhile.
By the way, as if there w
You'd absolutely, ABSOLUTELY limit the energy you emit (the frequency converted
input signal) to fit within the allowable "channel" you're repeater/transponder
is coordinated. That's no different with the FM brand of repeater. You're
responsible for your output. The IF is where you'd probably
uch an approach shouldn't work.

Yup, K3PGP had it in his house. I seen it several times, in person.

Do you know what gear they were using?
I think I do remember using one near Indio, CA years ago, and it
sounded great. Just like simplex (which it should.)

There used to be Linear Translators that were land based. There was one
around the Pittsburgh area. I'm sure somewhere there are a few left, but
they are few and far between.

I would hate to see your insightful comment missed. I haven't seen
anyone else pick up on the part of your message about the linear
transponder. If someone wants to pass many different modes through a
repeater, you can't do better than a transponder. I've been on the

What do you guys know about the AOR digital modems? I understand that
is an open protocol. Seems a little expensive, but if it sounds good
maybe we can build some kind of cheap encoder/decoder?

Steve,
I think your interest as with many Hams with D-Star is the use of
digital voice. We use it every day in cel phones, HDTV is here for
some, and with P25 rigs the interest is there. I am sure P25 is
great, but experimenting with digital no matter what format is a good
start.
