Our satellite ground station has been jammed for about a week with 60 dB
over pulse (spread spectrum) Looks and sounds just like Wifi but from
below 420 to above 460 MHz. Yestereday we built up a portable USB
receiver and attenuator and began measurements.
Went everywhere in the building and outside. Could be heard 40 dB over
everywhere in the building.
But darned if the signal wasn?t always just a bit stronger right at the
Ground station console.
Switched from omni to a hand held beam. Still signal seemed strongest
right at the console. Turned off everything one by one. No change.
Completely disconnected antenna, attenuator and cable but signal was still
S9 into the portable receiver (AOR AR5000) and good enough for sniffing.
Still strongest right on the console.
BINGO! It was an FRS walkie talkie, not used in years, that someone had
pulled out of its charger (it was dead) and re-inserted a few days ago. As
the dead FRS slowly attempted to charge up, somehow its processor must have
gone wild trying to power up and that was it!
Remember, nothing electronics anymore has a real OFF switch. Just a
processor that is always ON to sense the switch.
When I pulled the radio from the charger, the noise instantly stopped and
nothing we can do can recreate that one-in-a-million condition. And the
FRS radio is still dead.
But we can finally hear the noise floor again on the UHF band.

I'm looking for a very specific set of plans I remember seeing in QST and am
having difficulty finding it this morning. The design placed the HT antenna
at the location of the driven element, eliminating the need for feedline.
I understand this is a compromise antenna, but there is an unusual
circumstance requiring it temporarily. Any links would be appreciated.

Drew,
It was an article from the May 2008 QST, pages 42 and
43, titled "Dual Band Handy Yagi" by Thomas Hart AD1B.
It is available in the online QST archive at the ARRL

Hello,
I manage to grab what appears to be the XW-2 CAMSAT CW beacon.
Time UTC: 23:07

Frequincy: I think it was 146.660 Mhz
Mode: CW with AFC enabled

I'm guessing that this is the XW2 CAMSAT beacon?

Do you send out some sort of QSL conformation card? I don't know since I
never done this before.

We are in process of development of Student Satellite Ground
station for amateur satellite. we need to select rotor and antenna s for
amateur satellite ground station. we initially worked that we need 17db gain
for our polarized antennas for this purpose we need to have stacking of
antennas in order to achieve the desired gain in UHF and VHF band.
can anyone know from where we can purchase antennas having
1.VHF band (144 ? 146 MHz) gain 17 dBi transmit and in for receive 17 dBi in
UHF band polarization Circular
2. we narrow down two rotors from yaesu a) G5600 and b) G2800 rotor which
will be separately required elevation and azimuth.
Now the specific queires are
Question 1:we dont know where to find antennas of 17dbs. or we need 3
antenna in stacking mode having accumulated gain of 17db.
Question 2: we dont how how to finalize rotor. we have ICOM 9100 and we are
currently tracking satellite manually.
Question 3: how to calculate that these rotor will be sufficient for the
load of our antennas.or the g5600 will be enough for stacking of three
antenna's load.
any help much appreciated

Hi all,
I will be doing another Radio Merit Badge workshop class at the National
Scouting Museum in Irving, TX, EM12 this coming Saturday, February 6th. As
is my normal practice, I will be including in the activities, an AMSAT
satellite pass. This time around, we will be attempting to use AO-85 on
what for us will be a 1713Z AOS, 73 degree Max Elevation pass. We will be
using K2BSA/5 so please listen for/call us and lets show these 13 Scouts the
fun and excitement of Amateur Radio in space.
You can also find us on HF, probably 20 meters around 14.290 especially
between 1900Z-2000Z and 2115Z-2230Z.
Looking forward to hearing you on the birds/bands.
