Mr. Larry:


Good afternoon, this same 145,800 khz FM interference occurs in Bogot?
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.

Looks as though the Eutelsat bird launched by ESA yesterday has been lost.
It has suffered a propellant leak and is stuck in it's transfer/parking orbit.

Jeff:

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.

Jeff,
Check to see if the 10M band is open in your area.
Signals from space on 10M will be weak or not heard depending on how good
the 10M opening is. They can't get through the ionization layers when the
band is open. Signals 2M and higher are not effected by the ionization
layers.
Art, KC6UQH

Hi Jack

I have a Kenwood TS2000, which is very similar to the IC910.
For this discussion one important difference, the TS2000 has
a build in TNC, which can be used on either bands & sat mode.

Many years I simply connected that build-in TNC to my PC
and used Alogger under Windows (via RS232) for packet.
Mostly ISS APRS, but also to command RAFT, ANDE, etc.

Two years ago I bought a 2nd hand PK96, external TNC,
which I connect to the TS2000 (ACC plug) and PC (RS232).
Works fine. It allows me to use the build in TNC on one band
and the PK96 on the other band. Also, when I use the build-in
TNC, I cannot use CAT (doppler) access. So to do AND doppler
compensation (HRD) AND packet I need the external TNC.
Also with the PK96 I use ALogger.

Another option is to feed the audio to MixW, and create a virtual
link in SW: connect MixW to Alogger, then you can set up an APRS
Satgate without hardware TNC.

http://www.youtube.com/watch?v=FSFVTN2KKog shows how
ISS APRS is decoded by MixW.

Audio can directly be decoded by MMSSTV for SSTV (both TX/RX).
A SW only solution gets you running for SSTV. I did SSTV over HO68
this way: http://www.pa3guo.com/ho68_sstv_dec30_007.jpg

One year ago I added an interface between the radio & PC, to
decouple them physically (for 20+ years I was 'unsafe'). For this
I use a kit from http://www.ezkits.eu/. This is insurance only, it
doesn't add anything new.

Then, I use HRD for Doppler control, but it can do much more
including decoding of many digital modes.

When you connect the audio of the IC910 to a PC and run MixW
you are operational to receive APRS already ! Maybe start there
and extend then step by step. (oh, you then can also decode
9k6 from AO51)

Success !

==============================
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

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!

Hi Drew

JARL command team tried to activate the transponder on 10/29 20:20 (UTC)
10/30 07:33(UTC) 10/30 19:18(UTC). So far no reply from her.
It is not good news.

Hope she will back soon. 73

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

Here is the November schedule for AO-51. This month we are catching up
on several requests for L, S and even 38k4 BBS time. In January AO-51
leaves continuous illumination for many years and many of these modes
may not be possible due to power budget and battery condition. However,
if we find these modes underused this month, we may modify the schedule
as we go.

My 10M antenna is a 4 element quad which is part of a 10/15/20 M quad.? I
have noticed since the days of RS10/15 etc that the reception is much better
off the back? on 10M.? If I remember (not sure) it is cut for the lower part
of 10M, so at 29.45 either the reflector is acting like a director or the
first director is acting like a reflector.? In any event when I operate mode
A I??always aim the "back" to the satellite, there is a? significant
difference in reception between the front and back.? So if you're? using a
multi band beam of some sort you might try "flipping " it around and see how
it works.? At one time I built a horizontal 10M loop hanging from a pole,
then later added a reflector a few feet below it, essentially a 2 element
round quad looking up.? I would switch between the horiz. quad and the?round
quad depending on what the elevation was.? Yes indeed those RS days were the
good old days.? I enjoyed and learned a lot back then.

Subject: [amsat-bb] ?AO-7 Mode A antennas

I notice, looking at the logbook on the AO-7 website that the Europeans
utilize
Mode A alot more than use here in NA. ?Since the downlink frequency is in the
upper 10 meter band, and I wondering what antenna they are using for
receive? ?I
have tried dipoles, horizontal loops, G5RV, etc to pretty much zero luck in
hearing the bird, even with close passes.

Any info would be appreciated..
