I want to thank W0SAT, WA4NVM, W4DBT, W5DID, W0RDE for their efforts in
contacting me during my SO-50 summer camp demo here in Winter Springs, FL
this morning on the 14:01 UTC pass. Also, any other stations that might have
been trying for us. You all made the presentation a great success.
Let me know if I can ever reciprocate the favor.
73s,
Dave, AA4KN

The G-5500 can accept a 2-1/2" mast. And the 2m KLM is about 13' long so I
need to get it up at least 7' in the air. So I was thinking of using a
piece of electrical conduit. Not EMT (the thin-walled stuff), but rather
IMC, which is thicker walled (0.095" vs. 0.065") and readily available at
home improvement stores. 2" trade size is 2.36" od so it will fit the mast
brackets on the rotator fine.
There is an even thicker electrical conduit GRC which is 0.146" wall, but
at twice the price and a trip to Grainger (not out of the question but not
convenient either) I can't help but wonder if that's overkill.
The conduit comes 10' long so I'd put 3' in the ground, say a 12"x36" hole,
filled with concrete. Maybe filling the conduit with concrete as well.
I'd appreciate any comments as to the feasibility of doing
this...particularly the conduit size and hole size for concrete fill.

I am helping out with the organization of a station that will be
activated at the Boy Scout Jamboree.
They will have a scheduled ISS contact at some point as well as other
activity on the various satellites. We have SatPC set up and running well.
When we switch to the ISS 144/144 setting in CAT control the TS-2000
does not switch
the sub band to the right frequency. We can set the coordinated
frequency into
a channel and just do split operation I guess but would like to know why
SatPC will not do it.

Is the "other" object, a "known" object and is not named cos' its a hush

ahoy,
what ever happened with the 13 orig colonies event that n3tl / Tim
started last year ? there was some chatter here about it, but i did not
hear any stations (only worked 2 or 3 passes) on july 4th weekend, and have
not seen anything else on the BB. maybe next year ? or anytime ! it
seems like there is a gap in WAS for many with all those small, eastern
states. i may be activating some grids in nor*cal soon, stay tuned. thanks
and happy bird watching from the wild, western, big states.
too bad we dont have 50 oscars !!!

Joe,
Are you using the special SATPC32ISS program? It will be in the Windows
program menu. It is needed for modes where the TX and RX are in the same
band.

Robert,
We did have the "Original 13 Colonies event, here is what was posted. I was
WB2OQQ/K2A and I made over 108 contacts in the three days. Dave, took over
for Tim, see you next year!
73's Pete
WB2OQQ
www.massapequanyweather.com
Hello,
We have ten out of the thirteen colonies represented.. You can make up
special QSL cards for your station to send to whoever you contact if you
choose. As far as callsigns go, I was unable to get special calls for us due
to time( selling house, buying house, and 8 week old baby), so we will do
like we did last year, using our own calls with a /K2A, /K2B, /K2C and so
on.
Here are the calls-
NY- Pete, WB2OQQ/K2A
VA- Steve, NL7VX/K2B
RI ---------------------------
CT- Paul, K1PL/K2D
DE ------------------------
MD- Bruce, WA3SWJ/K2F
GA- Tim, N3TL/K2G
MA- Dave, KB1PVH/K2H
NJ ----------------------
NC- Mark, N8MH/K2J
NH- Rik, N1XED/K2K
SC- Art, K4YYL/K2L
PA- Rich, K3BFS/K2M
Here is the email I got from Ken with more details.
Hi Dave: All I need is just the number of contacts each colony station made
with other stations for the special event. Like I made 1285 contacts from NY
as K2A during the SE with other stations in 2009. We are going on the honor
system as far as the contact logs are concerned. It is just to much to check
for each certificate request. 12,500 in 2009. I believe most hams are honest
:) .. So each Sat.operator representing a Colony State must email me with
only one number-the total contacts made on Satellite..for the special event
only July 1st to July 5th..It doesn't matter if you cant get all 13 colonies
on Sat, you got 10 already. So if an operator gets 10 of the Sats, he can
get the other 3 on HF! for a clean sweep. Go to my bio KU2US on QRZ.com and
read all that is there. An operator is eligible for a certificate if he
makes one contact or in between to all 13. If YOU the Colony station would
like to also contact all 13 for a certificate, then YOUR state is counted
automatically, so you would have to only get the remaining 12. THIS log
needs to be sent to me for a certificate. The cert. is free to all colony
operators.
Thanks-Ken
I think that is all, but if I missed something, give me a yell.
Have fun on the birds!!!! If anyone has questions, feel free to email me.

Earlier today I caught a nice, high elevation pass on SO50. There was a
posting a while ago suggesting that switching to FM-Narrow helps to get
around the SO50/AO27 birdie on the radio and I can confirm that it works! I
got on just before mid pass but was able to copy SO50 during the rest of the
pass, even when the downlink was right on 436.800. For those of you wanting
to do AO27 and SO50 with the Kenwood TS2000 give the FM Narrow mode a try,
you will be surprised. My downlink antenna (as well as my uplink antenna)
is a Cushcraft A270-10S dualband yagi with no elevation, no preamp, and
horizontally polarized. Now if I can just get the SWR problem fixed on
2m.....

Are you using SatPC32 or SatPC32ISS? SatPC32ISS is a special version
designed for same band ISS use. It is located in the same folder as SatPC32.

Robert,
We were on from the 1st to the 5th. Next year we should do better as far as
stations on the air, this year was another last minute scramble.
I will be sending QSL cards for those that requested them as soon as I get
situated at the new QTH.

Hi Scott,
The 10' galvanized pole trick is exactly what I did in my back yard. I used
a hand post hole digger to go down 32" (until I hit a big rock) though I had
planned to go down 36". The pole was cemented into the hole but I did not
pour cement into the pipe.
The G-5500 sits on top with a 6' cross boom and a 7x7 432 on one side and a
5x5 146 on the other.

Since I live in a rental, my mount had to be temporary. I mounted a 3 ft
Radio
Shack Tripod onto a 4'x4'x3/4" plywood. Used a super large/heavy stepping
brick
to anchor it down, plus placed large river rock ontop. Mounted my G5400
Azimuth
rotor just above the tripod, then placed 5 ft of 1-1/4" EMT mast, with the
Elevation rotor and horizontal PVC with wooden dowel insert. Even only
using an
Arrow now, but still gives enough strength to when I'll get a "real antenna
setup, again". See photo....

Subject: [amsat-bb] pole mounting az-el system
I was planning on pole-mounting an az-el system:
> KLM CP yagis (the shorter ones)
> TekSharp 1.2m dish with dual-band patch feed
> 8' fiberglass boom
> G-5500 az-el rotator with mast brackets.
The G-5500 can accept a 2-1/2" mast. And the 2m KLM is about 13' long so I
need to get it up at least 7' in the air. So I was thinking of using a
piece of electrical conduit. Not EMT (the thin-walled stuff), but rather
IMC, which is thicker walled (0.095" vs. 0.065") and readily available at
home improvement stores. 2" trade size is 2.36" od so it will fit the mast
brackets on the rotator fine.
There is an even thicker electrical conduit GRC which is 0.146" wall, but
at twice the price and a trip to Grainger (not out of the question but not
convenient either) I can't help but wonder if that's overkill.
The conduit comes 10' long so I'd put 3' in the ground, say a 12"x36" hole,
filled with concrete. Maybe filling the conduit with concrete as well.
I'd appreciate any comments as to the feasibility of doing
this...particularly the conduit size and hole size for concrete fill.

John,
I built essentially the same support: 3-foot RS tripod on plywood
square and 6-foot mast; used for roving in the back of my pickup with
a 3-element 6m beam, 2m & 70cm & 33cm yagis. It is high enough to
clear the roof of the truck cab but not snag overhead wires on the
road. It also is very useful for tuning antennas before being
installed on towers or other high points. I have it for temp
antennas if those "hurried" installations.
It may get semi-permanent use with a U100 rotor and 4-foot vertical
loop antenna for LF/MW frequencies as a receiving antenna.
I have a second 3-foot tripod to mount a small 18-inch dish for
microwave ham radio.
