Jeff,
As has been said, he was coming through the reflector
because other stations were hearing him. I had the DVR
running on my hotspot and I was able to listen to your
entire exchange with him. I believe any problems were on
his end since he was using a Dongle. I keep these recording
for 30 days, so if you are interested, I can play them back
for you on WB8THD C local sometime.

Hello,
Driving around town yesterday day I happened to hear a
JA7 station calling "CQ Cleveland, CQ Cleveland..." I
thought this was in response to my "KG8IU listening,
Cleveland Ohio" call about a minute before. Perhaps he
heard the "Cleveland" but not the call sign, something
like that. Anyway, the local WB8THD C node is normally
linked to REF001C, so while certainly interesting, DX
wasn't unheard of. Over the next 10 minutes or so I
heard him a few more times. It seemed like he wasn't
hearing my replies.
So I had a thought. Perhaps he wasn't on the reflector,
but he was routing to /WB8THDC. "CQ Cleveland" would
make a lot more sense in that case. I've had an 880 for
near two months now but until yesterday I hadn't had need
of the RX>CS key. I tried it, verified his callsign was
in the UR field, and called him back. This time he heard
me, and we had a nice QSO.
Sounds like he was on a transceiver in that case, or just
a coincidence if he was on a dongle and your earlier
attempts were not heard due to stream collisions, a common
event on dstar hence the ¨dstar black hole¨ ops speak of.
I didn't think to check the RPT1 and RPT2 fields. I
imagine RPT1 was still my normal "WB8THD C", but what of
RPT2? In all the domestic examples I've seen, this is
set to the ".. G" callsign. Is that appropriate for
basic callsign routing as well? Or, was there likely
something more specific to him? I do know he was on a
dongle.
If he was on a DV Dongle, he cant have been callsign
routing, only possible on a dstar transceiver, a DV Dongle
only utilises cqcqcq in a urcall inication.
Yes RPT2 set to WB8THD G was required for callsign routing
or dplus linked transmissions to occur
via the gateway gateway internet connection. If that is
not enabled then only local repeater transmission occurs.
Now, the main question. It is my understanding that in a
dplus-style reflector link anything that hits the local
port is also linked to the reflector. If that's the
case, did the JA7 station's "CQ Cleveland" calls make it
into the reflector?
If he was on a Dv dongle yes as that´s the way he is
connected via a dplus udp port.
Not all incoming repeater callsign routed calls transfer
to dplus links, they used too in the past, but I
think that was stopped in newer versions of dplus on the
gateway machines.
Depends on the software configuration used.
Did my transmissions after I hit the RX>CS key? If so,
perhaps someone heard it. I think it was during the 9
o'clock hour EDT.
He did make a comment that many North American stations
"don't know how to contact Japanese station". I can
conclude only that we simply don't use callsign routing
much, so we don't know how to answer Japanese stations
that do. In his short message he did have something to
the effect of "CAPTURE CALLSIGN..", something he
mentioned in his audio as well. It took me a bit to come
up with what that might translate to, but I think RX>CS
was the key.
Sure sounds like he was using a transceiver here, did you
see JA7xxx/dngl on your screen?That should confirm he was
on a dv dongle, otherwise no-one would use that type on
message on a DV Dongle
that had a reasonable idea how it worked, you cannot one
touch a DV Dongle, its pure dplus link udp connection or
direct connection to your repeater gateway dplus udp port.
