FYI..
Just worked this guy on PSK31, but thought I'd pass on his QRV Sat activity
for those hard core sat operators. (I doubt I have the equip to make a
contact with him)
"Announcement: 1 man 1 luggage holiday-expedition, February 2013
During my 1 month time off between two employer, I will realize an old
dream: A Space-Radio-Dive Expedition.
January 31th to February 3th: KP4/HB9WDF - Puerto Rico (Includ visit of the
Arecibo Observatory)
February 4th to February 11: FY/HB9WDF - Kourou, French Guyana (I hope to
watch the Launch of Ariane 5 Rocket)
February 11 to February 21: FM/HB9WDF - Martinique (A beautiful underwater
world)
During my trip, I will be active on satellite (AO-7, FO-29, VO-52 and SO-50
and others if they are active) Also I will be active on HF in PSK-31 and
sometimes in SSB.
Good Luck

Next week (Feb 15) the earth will be visited by asteroid 2012 DA14

There is considerable interest in the astronomy community over plans to
do radar tracking of the asteroid. The Goldstone 70M dish will be
running MAX QRO with 435 kW.

Hi to everybody,
I (CO7WT) was active on the midday pass (~1720Z) yesterday...
I tried to make a contact but my RX radio is deaf.. it's a TK-860
channelized commercial radio that shows reduced sensitivity on the ham
band (I know that now...)
I was with an hombrew DK7ZB yagui of 6 elements and about 15dB of gain
but copies the signal so weak... it was just a try to test the gear,
Hector (CO6CBF) is guiding me about operation skills and told me that I
was loud in the pass and let every one calling for me... for those ho
heard me that time, please I'm sorry... this was only a test.
I will try to re-tune my commercial UHF radio for the ham band and will
try the contact in the future... so wait for me, and you will get the
FL11 grid...
73, CU on the birds from CO7WT.

Hi,
Yesterday evening I get hands on the tools and eyes on the gear, and
manage to deduce a procedure to adjust the sensitivity of my RX rig...
This was great, just with a Digital Multimeter measuring the noise level
at the RSSI on the FI IC of the radio I squeezed the sensitivity of the
rig to it's maximum... (from 0.45 v at the original setting to 1.1 v
whit my setting)
There has to be a more efficient ways, buy whit the tools on my hand
this is the only way...
From not hearing any station with the 15dBd yagui to 3 contacts on the
night pass of SO-50 with only 13 degrees in the pass... That's a
difference...
So CO7WT is ACTIVE on FL11 in every SO-50 pass that I can work... My
setup is working OK now.
Thanks to N8RO, K4FEG and WA4NVM to be my first satellite contact on the
bird, LoTW upload in progress...
I will to be active today in the 1638Z pass if you want to make a contact.

I know some might think this is off topic, but I enjoy seeing reports

Good Day all,
After a few years hiatis, I am contemplating getting back on the
birds. Because I currently live in an apartment, I plan on starting
the easy route using an arrow antenna. My question is, since I sold
my last HT about a decade ago, what is recommended for the current
models of HTs that have full-duplex capabilities?

There is only one currently operable FM satellite, and many of the sats due
to be launched this year are transponders or FM/DSB repeaters.
My suggestion would be to find a Yaesu 817 to get a toe into transponders,
and add -any- UHF receiver for full duplex FM. The little Baofeng UV3s are
like $45 and have good receivers in them.

Hi Costa,
Without using a Noise Generator in front of your RX and without
switching it ON and OFF, tuning the front end circuit of your receiver
for maximum swing of the noise level on the Digital Multimeter,
it is possible that your actual 1.1 volt is corresponding to maximum
gain and before the original 0.45 volt was corresponding correctly
to minimum Noise Figure and so to maximum sensitivity.
In a separate email I have sent to you the schematic diagram of a
very simple diode Noise Generator.

it's here http://www.uk.amsat.org/?page_id=12196
This evening Dr Chris Bridges appeared on the BBC Radio 4 show Material
World to talk about the UK smartphone satellite STRaND-1, due to launch at
the end of the month.
A recording is now available on the web until Feb 14, the STRaND-1 segment
