Good Afternoon, All:
Ever have someone tell you to read and read, again any email you write
before you send it ??
After church today, I went to get my email, and saw what I sent to "you
all". DAH!
A correction or two concerning that successful antenna. The one I
described was used with marginal success. The one that really worked
the best was in fact four slopping dipoles (at 45 degrees to the tower)
, one for each directional side of the steel tower --- N, E, S, W,
attached to the tower at about 40 feet up. Two relays gave me antenna
selection at the tower so I could have only one feed line to the shack.
I regularly worked all the AO and RS satellites is all directions.
Mode A to Hawaii was a real challenge, but I did it often.
Good Luck

Back to the "Good Ole Days". The best antenna I ever had to receive
sat signals on 10 meters was a pair of crossed dipoles at an angle of 45
degrees to the steel tower. It worked very well in several
configurations. The two dipoles were:
1. Just tied in parallel. Impedance matching was a little bit of a concern
2. I tried a pair of impedance matching stubs much like that used for
circular polarized antennas for 2 m and 70 cm.
3 I tried a pair if relays that allowed me to select any pair of the
four legs for some sort of directivity using the tower as a "reflector"
I used this configuration for all the old AMSAT and Russian mode A birds
with with much better than avearge success.
Helpful ?? Hope so!

I have not used an external 10M preamp yet, but I just got an ARR from
another op, so I'll be giving it a try. So far, I've used my FT-847
and the internal preamp. It has not been as consistent as Mode B, but
when the 10M signal is coming in, reception is usually fair to good. I
have noticed quite a bit of QSB at times, so it's worth being patient.

I've had recent Mode A success into Europe (Germany, France and
Italy), using a cut-down Radio Shack CB magmount whip. It's stuck on
to a large metal serving tray "borrowed" from the kitchen. I hide it
behind an easy chair in a corner of the shack.

Hi : Does anyone have any interest in Alliance rotor parts ??
I have over 20 boxes of various rotor parts in there
original boxes.
I will also throw in a few new CDR parts all for $100.00

I'm in the process of adding digital mode to my satellite station which consists
of IC910 radio using SATPC 32 12.8A. I will be using a Signalink USB & would
like to know if this is the way to go. I will be using it for packet,
digipeater, SSTV.etc. Two programs that I'm looking into using are MIXW & or
mltimode. I would appreciate any suggestions or help about moving foreword with
this configuration.
Thanks for any input. Jack WA1ZDV
Mr. Larry:
Good afternoon, this same 145,800 khz FM interference occurs in Bogotá
Colombia, there are several telephones in service, brand SENAO, which are
sold freely without control of the communications authorities
Personally I can not work as an amateur radio on ISS 145,800 kHz FM
frequency, sometimes the case with the satellite AO-51.
Amateur radio frequencies are occupied by squatters, such as taxi companies,
hotels, among others, however that writing and recordings have been made
known to the authorities of Control
communications, but so far has resulted in a eradication of these pirates.

I have made a last-minute decision to operate from the EN80/EM89 gridline this afternoon. I will be on the AO27 pass at 1946z and AO51 at 2040z. There is a very, very slight chance I will NOT be on AO27 at 1946z, but that is a very remote chance.

Trying to setup Sat32PC, I have a G-5500 rotor and using an RCI-SE
control board.
I have been using Linux gpredict and hamlib to control rotor OK but
wanted to try Sat32PC so trying setup a system.
ARSWIN says I'm at 45 degrees when antennas are actually at 90 degrees.
If I tell ARSWIN to go to 90 degrees antennas will then be at 180
degrees.
Nowhere in setup can I find something to correct this.
