Old geezers like me are prone to ramble on so please cut me a little slack.
Almost 50 years ago I made my first contact on Ham Radio. While
waiting for my novice license to arrive I got my station up and ready
to go. The license arrived in the mail and I rushed into my room
plugged in my only crystal, tuned up my DX-35 on 40M and made a
contact. I let out an uncontrolled cheer when the guy came back to me.
My mother rushed into the room afraid that I had hurt myself. I told
her that I was ok and had just made my first contact. She asked me
where the other station was located and I told her that he was in
Milwaukee (about 90 miles to the west of our QTH). She said politely
"Oh! Milwaukee". It was thrilling for me.
A short while ago. I had a nice CW contact on FO-29 with a Ham in
Illinois. Since I live in the Packer state, Illinois is not very far
away. It was thrilling for me.

I just put this all together today, using the instructions VK2DAG has up
at http://dl.dropbox.com/u/5513613/IC-910%20SDR%20Mod.pdf, and all I can
say is WOW!
I should have done this a long time ago, instead of messing around with
the VR-5000 and such.
Now, has anyone figured away to let SatPC32 do Doppler control, but
still have click and QSY capability from Spectravue?

TO All,
This is just another thread documenting Pioneers, (the ones with the arrows
in their backs). Isn't this the same as 200 Meters and down that happened
almost 100 years ago?
The experts at the time decided any communications on frequencies above
1,500 KHz would only carry a hundred miles or so and were useless for most
communications. Everything above 1,500 KHz was given to the Radio Amateurs
to experiment with. Once the experts were proven wrong, the government took
most of the spectrum from the Radio Amateurs, assigning it to commercial and
government interests.
Amateur Radio Operators pioneered communications by satellite with the OSCAR
satellite series. Communications by Satellite has been led by Government and
Commercial interests since the 80's of the last century. At least this time
they haven't reassigned spectrum, but government support is no longer
provided for experimentation or emergency communication via satellites.
New innovations now come from groups, not individuals because of the
combination of skills needed in engineering to develop a new innovation. It
is difficult to assemble a group of Amateur Radio Operators with the needed
skill sets to compete with commercial development and the development of
IC's to support new technology is economically beyond our reach. The days of
Edison and Bell with new inventions are gone.
If we all hit the lottery, would we rush out and buy a launch for a HEO?
Amateur Radio Operators represent 1/2 of 1 % of the US population, even the
politicians have no interest in us.
Art,
KC6UQH

Ok..then I can do this.
No HEO so I wont pay my dues. I think AMSAT Italia should start right now
building a real satellite. I have been waiting and complaining for years.
Why wont they build it. Come on who cares about money just do ir so I can
stop writing daily about how schools are stealing our frequencies. When did
hams own frequencies? Nevermind. Beep sats and bleep sats and leo sats and
easy sats are all suck sats so I will not support any AMSAT
So how about I post that again and again day after day, week after week,
month after month. You can after all simply delete it when you see the

Hi folks,
I've just obtained a nice, old, but disassembled, KLM 144-150-16C 2m
circular antenna. I think I have all the pieces (yea!). That, plus a tree
trimmer, and I should be in great shape for an upgrade. The old antenna is
a linear (vertical) 8 element beam of unknown pedigree. It's been working
fine, but I couldn't pass this one up.
Three questions:
1. The antenna does not have a polarity switch. The instructions are for
RHCP ("as used by Oscar-7" to give you an idea of it's age!). Given that I
don't (yet) have a polarity switcher, is that still the best polarization?
2. I have a 2m preamp that I have mounted some 10' away from my current
antenna, on the mast; I'd like to put it closer. Is it ok to mount the
preamp on the antenna itself, between the elements? I'm guessing not. How
about on the cross-arm, a couple of feet from the antenna boom?
3. The instructions recommend routing the cable out the back of the beam,
and looping it over to the support mast. But that won't work well as it's
rotated in elevation (it will get caught on the stuff below). My plan is
to run the cable forward and then sideways out at the mount point in the
middle. Will this have a significant effect on the polarization? The
cross-arm is a wood closet pole, not metal, but I'm thinking that the
antenna should be mounted in the X orientation instead of +, to lessen the
effect of the cable shield on the pattern. Good idea, or not?
Thanks,
Greg KO6TH

I gotta say, I JUST LOVE FRANK'S COMMENTS !!!!!!!!!!!!
First, I applaud Frank's accomplishments in such a short time frame. I kind
of took the same track 2 years ago and managed to get my VUCC, and then seem
to have slowed, but have a renewed interest in using the existing sats
remaining. No moping and crying about what was and what may not happen in
the future. Just use what is there.
I do not belong to AMSAT and will not in the near future. AMSAT reminds me a
lot of the 'Limousine Liberals' in a particular political party. They bitch
and moan about what suits their particular agenda and fail to recognize the
positive or take steps to 'fix' the practicable. It is quit possible that
there will be NO workable amateur sats in the future, but whining about AO40
and 'cube sats' is not productive.

I guess I am fortunate, I just came to satellite radio about 15 months
ago, I missed out on the HEO's and all of the great "Good Old Days" of
satellite radio, but in those short 15 months that I have been on the
satellites I have some how managed to work 669 grid squares, confirm 581
of them (and Yuri still owes me 40), I have worked all 50 states on the
satellites, I managed to work all but 1 of the Canadian provinces,
worked 11 European countries, 8 or so Central American countries and 5
South American countries. While this may not seem like anything to the
people that had the opportunity to make use of the HEO satellites, it
has been a hell of a lot of fun for me.
In the last week I have had no less than 2 contacts with stations that I
was their 1st satellite contact.
I may not agree with how things are being handled with AMSAT, I damn
sure can't get enough information to suit me but I am not going to quit
operating the satellites until there ain't nothing to work up there.
And by the way, I worked all of my contacts with 2 M2 terrestrial
antennas set at a fixed elevation of about 20 degrees and they are
mounted on a Glen Martin 8' Tower on my back deck.
One thing for certain if you get off the satellites you have for sure
made your last satellite contact, Heck with all the "beeping" &
"booping" birds that are going up all that will be needed is a bunch of
SWL's to listen to the telemetry!
WORK 'EM TIL THEY FALL OUT OF THE SKY!
That's my humble opinion!
Everyone have a nice day

Hi Greg, HO6TH
Switching from RHCP to LHCP is the best particularly with LEO satellites.
RHCP was nice with OSCAT-10 and OSCAR-13 because they were spin
stabilized over the Z axis wich is not on the actual LEO sats.

10' is only about 3 meters long and if you use a good coax cable with
low losses at 144 -150 MHz the attenuation will be fraction of a dB
and the Noise Figure of the preamplifier will be not deteriorated
or increase significantly.

Now with my system back up and running I can pay closer attention to the
"goings" on. We regularly read here about the usual complaining and belly
aching about FM vs linear sats, no HEO. Whining that no one is listening to
"ME". We appear to coddle the new beginner, and we should provide them the
necessary guidance to get going. Now we have to smooze the "educational"
aspect of satellite creation. The caveat should be, hang a transponder on
it. I read of some of our European friends dismanteling their antennas,
others refusing to join AMSAT or any other satellite organization for
whatever reason. I don't like to pay taxes but I must, I/we should look at
it the same way. Those "things" up there in space just didn't just happen.
The days of a cheap/free ride are gone, it's all about money to get there.
With the bean counters in charge now. We try to make "easy sats". Personally
I don't want easy sats. I want hard sats. I want to be challenged to the
point of ripping my hair (w!
hat's left) out. I started with satellites in the mid 90's not because it
was easy, but because it was hard. It made me work at it. It challenged my
limited capabilities, and through that I gained confidence to try even more.
Like try to work a LEO with a L/S transponder. Try keeping up with that
puppy. My late father told me, "the difficult we do immediately, the
impossible takes a little longer". By Challenging ourselves we keep the old
curmudgeons happy (if that's possible). Back in my corner now. I'll try not
to relive the AO-40 days (sobsob) here, I know it gets old for some of you.
Though it was a killer satellite!

Dear everyone,
According to latest news from JAXA, deployment of the 5 CubeSats to space by
the robotic arm of Kibo module on the ISS will be carried out on Thursday,
September 27. Here is the plan:
- First, 15h10 to 15h20: WE WISH and RAIKO from POD #1
- Second,16h30 to 16h40: TechEdSat, F-1 v? FITSAT-1 from POD#2
All time in UTC. The event is planned to be broadcasted live on the
following websites:
http://iss.jaxa.jp/iss/jaxa_exp/hoshide/library/live/
http://www.ustream.tv/nasahdtv
30 minutes after deployment from the station, F-1 will begin transmitting
beacon alternatively on its main and backup channels. Telemetry and beacon
data from F-1 contain critical information about the satellite?s health
(battery & solar cell voltages, temperature readings) and they are very
important to us, especially in the first week of operation. Thus, we would
like to ask the amateur radio community to help in tracking and receiving
data from F-1 CubeSat.
Here?s a quick summary of F-1? frequencies:
- 145.980 MHz: main channel, 1.0W RF output, FM, AFSK 1200bps, one
telemetry packet every 30 seconds, operates in the dark by default (but can
be commanded later to operate in sunlight as well)
- 437.485 MHz: backup channel, 0.2W RF output, FM, PWM CW beacon,
each beacon transmission lasts about 20 seconds then 60 seconds delay, only
operates in sunlight
More information and guide to download F-1 telemetry decoder can be found at
http://fspace.edu.vn/?page_id=27. Decoded data can be submitted to us via
the telemetry decoder or by sending to me directly (thuvt@xxx.xxx.xxxx audio
records are highly appreciated.
Please feel free to send me a message if there is any question. We would
really appreciate your kind support!

Dear everyone,
According to latest news from JAXA, deployment of the 5 CubeSats to space by
the robotic arm of Kibo module on the ISS will be carried out on Thursday,
September 27. Here is the plan:
- First, 15h10 to 15h20: WE WISH and RAIKO from POD #1
- Second,16h30 to 16h40: TechEdSat, F-1 v? FITSAT-1 from POD#2
All time in UTC. The event is planned to be broadcasted live on the
following websites:
http://iss.jaxa.jp/iss/jaxa_exp/hoshide/library/live/
http://www.ustream.tv/nasahdtv
30 minutes after deployment from the station, F-1 will begin transmitting
beacon alternatively on its main and backup channels. Telemetry and beacon
data from F-1 contain critical information about the satellite?s health
(battery & solar cell voltages, temperature readings) and they are very
important to us, especially in the first week of operation. Thus, we would
like to ask the amateur radio community to help in tracking and receiving
data from F-1 CubeSat.
Here?s a quick summary of F-1? frequencies:
- 145.980 MHz: main channel, 1.0W RF output, FM, AFSK 1200bps, one
telemetry packet every 30 seconds, operates in the dark by default (but can
be commanded later to operate in sunlight as well)
- 437.485 MHz: backup channel, 0.2W RF output, FM, PWM CW beacon,
each beacon transmission lasts about 20 seconds then 60 seconds delay, only
operates in sunlight
More information and guide to download F-1 telemetry decoder can be found at
http://fspace.edu.vn/?page_id=27. Decoded data can be submitted to us via
the telemetry decoder or by sending to me directly (thuvt@xxx.xxx.xxxx audio
records are highly appreciated.
Please feel free to send me a message if there is any question. We would
really appreciate your kind support!

At ISS altitude it will take care of itself after a few months so don't
worry about space junk.
Thanks,
Thu

Insult them, that's a great way to get groups to consider a repeater on
board. Believe it or not, some people enjoy the peacefulness of receiving
telemetry versus the the fight with inconsiderate operators.
