RE: [Repeater-Builder] Converting the Kenwood TKR-820 to use with D-STAR

[Mike Morris]

The biggest problem with multimode systems you describe (including
the quantar) is that you have two separate user pools on a single box
on a single channel.   The DStar users don't have any idea of what is
happening on the conventional side and the conventional folks have
no idea what is going on the digital side.

This is not what you want on an event - be it a city parade or a
multi-injury traffic accident or a Katrina.  You want to promote
communications, not build walls.

And a little trick - the URL (link) won't break with word wrap if you
put "<" and ">" characters around it (and if it does, your mail reader
is broken).

RE: [Repeater-Builder] Converting the Kenwood TKR-820 to use with D-STAR

[Mark]

John,

I currently am Trustee for a TKR-820 operating on 444.5500.  I wonder - is
this conversion "dual-mode" capable, meaning, can it be accessed BOTH via
D-STAR and analog radios, or does it render analog access unusable?  I do
not want to do this if it eliminates analog access, since this is an
Emergency Management-affiliated repeater and many users in my area are not
D-STAR capable.  As such, I'd have to maintain a dual-mode system, similar
to those using Motorola QUANTAR repeaters for digital (APCO 25) as well as
analog access.

Next questions is, my machine is a multi-receive site (read: SpectraTAC)
system - is the D-STAR processing done on the FINAL received signal before
being passed to the transmitter, or would I need to convert all the
receivers in the system to be compatible?  In my system, I do not use the
internal receiver in the TKR-820 - I feed a voted signal in from the
comparator for repeat.

Photos of my system (with one receiver configured) can be seen at the
Repeater-Builder Yahoo group:

st
Look at those associated with WW9AE

If it can be configured for a dual-mode/multi-RX site configuration, I might
seriously consider adapting our machine.

Thanks!
