Her Majesty's Royal Mint special event. (GB4RME)
Members of the Barry Amateur Radio Society will be operating from 'Her
Majesty's
Royal Mint' at Llantrisant, South Wales, UK,call sign - GB4RME (Royal Mint
Experience) between July 30th and August 5th 2017.
Locator: IO81HN WAB:ST08
The hours of operation on a daily basis have been limited, but we expect to
be
operational between 0800 - 1730 hrs GMT.
It does restrict operation for satellite operations and passes in addition
of course AO-73 operates in data mode Monday to Friday when illuminated
(Auto mode) However on the first Sunday of the event (30th )
and the last day (Saturday 5th August ) the transponder mode should be
available if commanded.
Some satellites may only have early passes on a daily basis and if I cannot
get access to our op's room on site I may have to use a portable set up
from the car park
The general other activities of the event will be on the HF bands using
CW, SSB, DATA RTTY and JT65.
This event will also include an exhibition and demonstrations of "Amateur
Radio."
How key events especially using satellites,the ISS are key players in the
role of education and "STEM"
Note also this event also co-incident with the event taking place for
"YOTA 2917" ( GB17YOTA )
and should be significant as a prime contact for youngsters participating
from world wide.
This special event station is a world first, operating from within a Mint,
and a
Royal one at that.
Details about the mint can be viewed at:
http://www.royalmint.com/en/the-royal-mint-experience
QSL via GW0ANA, direct, by the Bureau, LoTW and ClubLog.
There will be a Web page set up for the operation on QRZ.com.

All,
I am in the process of setting up my station to receive telemetry from AO-85
and then AO-73. I have come across a number of references to a ?Virtual
Audio Cable? being used to connect the RTL-SDR dongle to the telemetry
software. A Google search returns a number of hits for such a cable. Some
free, some not. Does anyone have any experience using any of these products
in the application I want to? If so, is there one you would recommend? Stay
away from? Hints, pitfalls? Any insight would be appreciated. I just hate
downloading product after product for evaluation without any prior
knowledge. Reminds me of the old BBS systems and shareware!
Thx

I use the VB Audio Virtual Audio Cable. It has worked for me for a
couple of years now. That kind of stuff is not intuitive for me, so I
had to dig into the tutorials and instruction manuals to set it up, but
it works just fine once you've finished. I have not had to make any
changes to it since I did the set up.
So, I don't have much experience with other VAC software, but VB Audio
works for me. And, if I can set it up, really anybody can.

For your purpose, VB Audio would be the way to go. It is free and simple to
set up. I have used it for test purposes on a range of computers, Windows
versions, and client software with excellent results.
That having been said, I use Muzychenko's VAC normally, mostly for
historical reasons having to do with Flex rigs. It has much more room for
customization, but a corresponding opportunity to shoot yourself in the
foot. The price is very reasonable for what you get, but not free.

All,
Detailed doppler measurements show that HAVELSAT is object 42700,
1998-067LH, and that SOMP 2 is object 42701, 1998-067LJ.
Thanks to Mike, DK3WN, for the hint.

Content-Type: text/plain; charset=ISO-8859-1; format=flowed
I may have missed something but I gather from the past info, that your
unit works, but the elevation meter doesn't indicate so? If this is the
case, I usually found this problem to be 500 ohm adjustment pot. They
are very light duty and will open up at small amounts of EMI (static
discharge). I had similar problems with my G5400 and it was the
elevation output voltage pot. Sometimes the op amps go as well. If you
need it, I think I still have a ZIP archive file of various individual
inputs of solutions from different people on their G5400/G5500 problems
and also rebuilds if you want it.
You could have lost the 500 ohm pot in the rotator itself. You can test
this by using a volt meter across the elevation rotator terminals as the
unit runs, or ohm meter without power and check the resistance across
the three terminals.
Good luck, hope you get it fixed.
