Just out of curiosity Carl, how can you tell that the JA station was
using a dongle ? I suspect the JA station was call sign routing to
Cleveland (CQ Cleveland) and because Cleveland was linked to a
reflector, all stations likewise linked heard the JA station. Why else
would the US station
The addition of Dplus to the native Dstar transport system can make for
some un-intended consequences. Folks did AOK without Dplus linking for
quite some time. Dplus is nice for tying repeaters together for wide
area operations and a great add on to the native system. For me, it is
easier
A wonderful tool Bert - I do wish the low speed data port could carry an
abbreviated form accessible to mobile stations without the benefit of an
internet connection.

DSTAR on 220 sounds like it would make a tremendous lot of sense.
Propagation similar to 2M - No Pave Paws ? Radar - clean spectrum

but could surely be overcome. Folks would for the most part be buying a
new Icom
Don't know about the 2820, but on an ID800 I ran a GPS emulator program
in place of the GPS receiver to feed the radio. I can put in any
coordinates I want. Do a search on messages or look in the files and
links sections - I believe the emulator program and some relative posts
are there.
Interesting side note. I was thinking 2 Ghz operational fixed links
were displaced in the US by PCS Cellular service - perhaps 960 Mhz or 6
Ghz ? Doesn't make that much difference - many applications use 960
Mhz. with a fractional T1 data channel.
Trunking repeaters just allows a large pool

It's easy to segregate into different banks. USA1, USA2, CANADA, etc.

Connect a small transformer across the loudspeaker (terminating
resistor) to isolate the dstar receive audio from the FM radio. There
is a +5 VDC signal from the micro in the ID800 used to mute the

There is no question Dplus makes contacts possible for more people, in

How would you use call sign routing if you obscured the callsigns ?
Call signs are a part of DSTAR and really the matter in my opinion is
having dstarusersorg log time and date and repeater vs call sign (maybe
a real call sign, and maybe not). DX Central manually does similar for
DX Spotting,

Welcome to DSTAR, John. Wonder if you are near a dstar repeater with an

Aside from the losses mentioned earlier in coaxial cable, (IR loss,
Dielectric Losses, and Radiation) under radiation, aside from the
percentage of shielding, the resistivity of the shielding also comes

For shielding to work perfectly, the shield conductor must have no
resistance.
Wonder if you are looking at a particular make and model ? I could do a
little looking and see if there is a manual with better detail. 73,
