To talk to WHO-IS and/or WHO-15, just send an APRS message to
that callsign-SSID with a single callsign in the body. It will
respond with information about that call's owner. If you precede
the call with "f " (F space) it will return "full" information.

Just do one message to WHO-IS and another to WHO-15. My
suspicion is that WHO-15 will be answered and WHO-IS will not be.
Ask the custodian what software/hardware their VK3RSA-1 IGate is
running and where one can get support for said IGate
functionality. And you could ask them to run the same RF test
through their IGate so that they themselves see the issue.
The easiest way would be with a Kenwood APRS radio while watching
their IGate logs, if it has any with requests sent to WHO-IS and
Of course, as you know, Yaesu APRS radios can only send to AX.25
-SSIDs, so they would never see any issues with WHO-IS (or WXSVR-AU)
because they could never initiate the original request.
As for VK3RMD-1, your Direwolf simply heard your own packet
digipeated by that station over RF. The messages are being
injected into the APRS-IS by VK3RSA-1 with no paths used, so any
other digipeated copies of the same packet will be dropped by the
APRS-IS duplicate suppression.

Correct on the station setup. The radio is just doing the RF part.
My station is capable of using APRS-IS, but I have it disabled
while trying to figure out why I'm not receiving return packets
from WXSVR-AU. And yes, I have added the "dash 15" to my station
callsign. I thought that it may have been why I was not receiving
those packets, but it has not made any difference. Still nothing
back via RF.
I had also asked the same question to the Australian APRS Users
group, and received this reply from "the custodian of the VK3RSA-1
APRS-!S messages to local RF:
Gate messages to local RF: = Yes
Message path: = WIDE2-1
Local RF heard max. digi-hops: =
Local RF heard buffer timeout
(m): = 30
Regarding your request : " try sending a callsign lookup to WHO-15
and WHO-IS.", how do I go about doing that?
For a quick test, I just enabled APRS-IS and sent a request to the
WXSVR-AU server and received this reply ...
So, I can receive the replies via the Internet,
but that would not be much use for anyone that is camping away
from the city with no Internet available to them.
One other thing that I have just noticed, and I am trying to
understand the direwolf output, is that, while the requests to the
WXBOT server were returned via VK3RSA-1, and I received those
request responses via RF OK, the requests to the WXSVR-AU server,
are showing in my screen grabs as coming via VK3RMD-1, so maybe it
is VK3RMD-1 that has the issue? Just my thoughts ...
Thanks for your help.
