At a new QTH and setting up a dual band quad antenna for 2m and 70cm.
I plan to make the 70cms antenna,the vertically polarised one, 2m horizontal,
as I believe this is the normal arrangement.
If anyone has practical experience that goes against this assumption I would be
interested, either direct on on the bb.
I don't have polar phasers, switchable delay lines or anything else its just a
straight choice, which one goes vertical.
They are on the same boom so I suppose I could go slant for both ?
Main activity here will be phone, VO-52, AO-51, FO-29 plus satellite telemetry
from cubesats etc.
Thanks in advance
At the 1850z pass, ARISSat passed at approximately 20 degrees for me. I hadn't tried the SSB transponder in a while, and decided to give it a go. Once I found my downlink, it was loud and clear throughout most of the past. Called CQ for several minutes, but no takers.
Those who haven't tried it, really should.

For those of you who are following the ARISSat-1 telemetry, we
now have a second web page with decoded telemetry available at
This page is intended to be viewed on a computer (or large screen
computing device). It shows all of the telemetry values that you
would see if you were running ARISSatTLM. The advantage of the
web page is that it is powered by submissions from other amateur
radio ground stations, and it is updated once a minute whenever
ARISSat-1 is in range of a telemetry forwarding ground station.
Since it depends on stations forwarding telemetry over the Internet,
there will occasionally be periods without any updates.
The original ARISSat-1 telemetry page at
is still up and running. The difference is that the "mobile" page is
designed to be viewed on a cellphone or other small screen
computing device. Both pages are updated at the same time
from the same telemetry. The "live" page just shows more
Please keep forwarding in your telemetry over the Internet. Also,
if you received any telemetry from ARISSat-1, even if you are
forwarding, please email the .CSV file(s) to telemetry at
arissattlm dot org. The .CSV files are in the "Telemetry" folder
which is in the ARISSatTLM folder on your desktop.
Thanks and 73,
Hi to all, this is what I have received from GAUSS team in Rome about my request of Info about Edusat, they talk about of "Non Amateur Radio satellite"...

Subject: Re: [CubeSat] Edusat operative or failure
this is the GAUSS group which is in charge of Edusat satellite.
We want to calm down Giulio: Edusat mission is carrying on flawlessly. We
have communicated with it and he told us that the weather is a bit chilly
but the panorama is great.
We have seen that many wrong informations are reported on the web. For
example, all the radio frequencies are wrong. Edusat is not a radioamateur
satellite and has an experimental license for communicating.
We didn't thought our satellite could be so interesting for the space
community. Thank you for giving us so much attention.

I have had similar experiences over the past few days here in Wales ( UK)
during the higher daylight passes
which now transpire.
I was really surprised how strong my downlink was and I only use an "ELK"
antenna ( with tracking ) software.
No replies to my calls but I did hear others keying / tuning on to my
operating frequency. Strange though
as I also know of reports from others whom had no response. Perhaps with
the rapid changes that have transpired one has to just be lucky with
conditions being concident.
Will also keep on trying - Good Luck to all and pleased to see that at
least the transponder has benn functional.
I am running ARISSatTLM software to receive the data from the ARISSat-1
satellite. I have seen several mentioning sending .csv files with
data. Is the ARISSatTLM capable of generating a .csv data file?
Perhaps a cut and paste of the data is done. I have used print screen
to capture what I have recorded. Is there a much better way to record
the data? I feel like I have missed something somewhere. At first I
did not have much success receiving the data. I think I was trying too
hard. One day I was getting disgusted with it all and just did nothing,
no tuning, no nothing. I received 9 frames of data perfectly. Once
again the philosophy of "if it don't stink, don't stir" applies. This
satellite has added many hours of fun to my amateur radio hobby.
what about the following link?
*Subject: [amsat-bb] ARISSat-1 battery
From: [email protected]

The ARISSat team seem to have reached the conclusion that the Silver Zinc
battery technology is not really suited for
an orbiting satellite with a 55 / 35 minute charge and discharge cycle. I
wonder if a couple of small
Lithium polymer battery packs would be a suitable replacement for ARISSat-2
note that there are safety issues with Li-ion technology,
but there are some small battery packs of 10Whr / 20Whr 30Whr modules which
have NASA approval for manned space flight.
>From the odd snippet of information on the power required during eclipse (is
7 Watts for 35 minutes) it looks like 20-25% depth of discharge for the
battery pack. That's probably OK for a 9 month mission ??
