<p>Hi all,</p>
<p>Yes, thanks Mark for putting the evening on. Some challenges were
found, and some met.<br>
It certainly showed up a number of difficulties and enabled some
targeted investigations.<br>
My own case, I could not get Vara FM to PTT my Tcvr. I use a
hardwired PTT with my IC706IIG.<br>
I have since found that the HF & VHF TX is on different pins
on the ACC plug. <br>
</p>
<p>All Winlink HF Gateways should be fairly equal - just distance
& conditions can cause variation. John 3ZRX <br>
would be able to say a lot about NVIS propagation. Thats why a
well spaced number of Gateways <br>
around the State and Country is very helpful. Also, Gateways with
a number of bands.</p>
<p>You can set RMS Express to inform you if an update is available,
and enables you to cancel an install if desired.<br>
It will nag next time you run. Always good to have that OFF - its
the last thing you want out in the field!</p>
<p>As for congestion - Im thinking a Zoom or Email or Text or other
checkin system at the start of the net...<br>
Control station collates Callsign, Frequencies & Modes and
where traffic directed. Then an allocation list is sent back.<br>
Reasonable time is allotted for each attempt. Move on if problems
- get through the list, then at the end, retry <br>
if adjustments need testing. Zoom active throught the period.<br>
</p>
<p>IE: 19:30 - 19:35 VK3MDH - VK3DPW Gateway - 80 Mtr - Vara
HF - Winlink Message - Message to <a class="moz-txt-link-abbreviated" href="mailto:datagrp@vic.wicen.org.au">datagrp@vic.wicen.org.au</a><br>
19:35 - 19:40 VK3LSN - VK3MIT Gateway - 80 Mtr -
Vara HF - Winlink Message - Message to <a class="moz-txt-link-abbreviated" href="mailto:datagrp@vic.wicen.org.au">datagrp@vic.wicen.org.au</a><br>
19:40 - 19:50 VK3MDH - VK3LSN -
144.2 - VaraFM - P2P - long text message (50 words).<br>
19:50 - 20:00 Vk3EQ - VK3YYF -
144.2 - Vara - Chat - Long text message (50 Words) <br>
20:00 - 20:10 VK3DPW - VK3MDH - 80
Mtr - Vara HF - P2P - Message with attachment.</p>
<p>Id like to do some more testing re: being able to read messages
not directed to you. <br>
It may be just the handshaking and the message &/or attachment
is not clear.</p>
<p>Anyway, thats my thoughts for now. I must look into Slack on the
PC.<br>
</p>
<p>Thanks</p>

<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Many thanks to all those who were able to
participate in last night’s digital session. It was an
enjoyable evening with lots of excellent discussions held on
Zoom. Had my hands full running Zoom and the two systems
keeping the stream going but I think we got there in the end.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I finally got my 2M Winlink system working
after many had left Zoom. I further tested Winlink P2P today
with Rik, VK3EQ and it worked flawlessly. I’m sure my list
below can be further expanded and I’ll upload it into
<b>Slack</b> under the Winlink channel. Please add your own
comments / thoughts in Slack so others may have later all our
collective thoughts in one place.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I was hoping next Friday evening we do
something similar if there is interest. This will allow others
to join us, to test or retest our systems, theories and share
ideas. If anyone has any idea’s how we could run the 2hr
session please let me know then mid next week I’ll issue the
Zoom log in details and how we will structure the exercise for
next Friday evening.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The aim is to see how if decided these
Winlink / Vara systems could be used in a WICEN activation or
public service event.<o:p></o:p></p>

<p class="MsoNormal">Assuming stations are all operating
on a single frequency it’s difficult to ensure
messages can be passed. How do stations operating on
single or multiple frequencies effectively operate /
co-exist. In testing a message for one station was
received and read by another. Messages are not
encrypted and could be intercepted. This also begs the
question re: other stations / other traffic operating
Winlink and causing interference. VARA HF Chat works
well when connections are made.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If multiple stations require chat
what benefit does Vara Chat bring over TRAK. Multiple
stations operating in the field require a TRAK / Mesh
like environment.<o:p></o:p></p>
