Guys,
?
I want to upgrade from my hand held Arrow to something permanently mounted
outside with and Ele/ Az rotor.
?
I have a single story home with roof peak at about 22 feet.? I can easily
mount a 10' - 20' mast directly outside the shack anchored in concrete and
bolted to my roof eaves.
?
If I use two ?masts sections I will get a net height of about 17' which
means?I will be "looking" through my roof on the lower easterly orientated
passes.? Gaining the additional height to completely clear the roof line will
be increasingly problematic.? How much should I be concerned about this, etc?
?
I'd like some real world feedback / suggestions.
?
Thanks in advance.

For the past several weeks, I havent heard the 14.282 20m net on at 1900 utc.
Last I heard when I talked to Larry W7LD more than a month ago, as he was net
control. Is the net still active? Course with all the contest chatter,
probably not be easy.

Harry,
Have you considered a roof tower? I put up one 20+ years ago, and have been
very satisfied with it. The model I have has a built in ladder, which makes
access to the components easy. The antennas obviously clear the house, and
all but the tallest trees. How tall a tower depends on the longest length
of antenna you plan to install. They are easy to install on a shingle or
similar roof, not so easy on a Spanish style or shake roof. I have used
somewhat sturdier anchors than are usually recommended.

My antenna height philosophy goes like this-I try get away with as much as I
can get away with considering, cost, XYL attitude, powerlines, falling on
neighbors.? The idea of, "just one more foot" can go on forever.? My roof line
already looks like a NASA facility.

I built my LVB up from the bare board which I ordered from G6LVB direct in the
early days. It was a fun home brew project. Mine is bare bones. It has no
display and?no buttons. It?just sits inside a Radio Shack box and does its
thing day after day. If you look at?my unit, the PCB?just has enough of the
components on it to?do the job which it does well.
?
I would highly recommend?the LVB, it works well and is supported well.

The $200 is a great deal. I helped sell every one we had on hand at the
AMSAT booth in Dayton. Another perspective, about 2 years ago I replaced my
ISA bussed motherboard for a new one. The only ISA bussed mobo I could
find(that was under $500) cost $190. Other then the two ISA slots, it had
the comparable performance of a $35 mobo! My next computer upgrade for my
sat control system will use an LVB to control rotors. The Kansas City
tracker ISA card will be heading to the Smithsonian Institution....

Hi Myles,
Simply stated---this is a very functional and easy to use track box,
with exceptional attention to construction detail when purchased
already assembled by AMSAT (thanks, Mike Young!).???It's a very fair
price at US$200.? (Price out the parts to build one up...it's a deal).
It's essentially plug in, calibrate, then play!

>> John -- I think Greg means the 8-pin DIN, not the mini-DIN ....
No.? The PSK-1 RS-232 port to the Computer is J10, which is a mini-8 DIN on
rear panel.
I am looking at the back panel of my PSK-1 here in workbench!
The PSK-1 also has 8-pin DIN (J2) for the TNC Modem Connection (via 20-pin
TAPR disconnect header on Tiny-2 or TAPR TNC-2);
and three 5-pin DIN connections: TNC Radio Connection (J4); VHF Radio (J1);
UHF Radio (J3) ---
the separate VHF and UHF radio connections were useful for the Icom VHF/UHF
radios (271/471; 275/475) of that era.
The PSK-1 and PSK-1T modems do have different rear panel connector types!
LOOK at the REAR PANEL (eBay auction # 320392587069 has a rear panel photo)
On the PSK-1T, there is an 8-pin Mini-DIN marked CONTROL (RS-232), I assume
that Gywn kept the pin out the same as the PSK-1
and would connect this to a PC serial port (RS-232) that is running a terminal
emulation or control program.
To the left is a Male DB-9 marked PACKET (RS-232) ... A manual for the PSK-1T
will confirm its usage/connections.
As I remember, and W3IO probably has a better memory, PacComm introduced the
PSK-1 for the PacSats launched at that time.?
Later, Gywn reintroduced the PSK-1T with some updates and suggested
modifications.?
I first saw a PSK-1T at the 1995 AMSAT meeting in Orlando (1995) --- shown in
preparation for AO-40.

Mark, I was watching that eBay auction (# 320392587069), but did not bid on
these items -- I already have one!
There were two PacComm PSK-1 and DFM TNC combinations for sale on QRZ a couple
of weeks ago at $35 per set or $50 for both (great deal)!
Yes, the DFM permits usage at 9600 AFSK (which one of the satellites did
support).

Hi Greg,
"//
To get me going can some one? please send the pin out for the radio 8
pin DIN for the DFM TNC.
Thanks de John K0CQW
"
Um..back to the question John asked--it was about the 8pin DIN on the
DFM, not the PSK unit.? The DFN TNC doesn't appear to have a mini-DIN,
so, that's why? I didn't think the mini-DIN answer was what he was
looking for :)
http://cgi.ebay.com/ws/eBayISAPI.dll?VISuperSize&item=320392587069
Excellent information, history and details, though, Greg!? Thanks!
In the shack I have a couple each of the PSK-1 and PSK-1T units, and
manuals.? The PSK-1T with the built in TNC is really slick (the "T"
designates the built in TNC, no disconnect header hookup needed!)
Hopefully the chatter will help John get his stuff going--but I think
he STILL needs the 8pin DIN info for the DFN....my hunch is that it's
the Paccomm "standard" pinout for hooking up the tx audio/rx
audio/PTT/GRND, but I can't confirm.

Mark N8MH

SuitSat-2 System Engineer, Gould WA4SXM kept the satellite community
updated on the system integration meeting taking place in Phoenix
this weekend. Reporting via twitter (http://twitter.com/GGouldSmith)
Gould said progress was occurring on several fronts.
The command receiver boards were assembled and ready for testing. The
command receiver and receiver boards were integrated for the first
time this weekend. The team was able to report that the receiver is
now providing good input to the SDX transponder and as a result the
transponder became operational and produced a signal on the output
with the CW, FM and BPSK signals. The transmitter was drawing 330mA
and produced +25dBm output in the test configuration.
System engineering progress was also report on additional issues:
+ SPI communications between the IHU and SDX were debugged
+ battery charging circuit undergoing testing
+ Spaceframe issues have started to be addressed to replace the
missing suit.

Patrick Stoddard, WD8EWK, will be at the ARRL Arizona State Convention and
Hamfest in Williams, Arizona, on 17-18 July 2009 - a Friday and Saturday.
He will have an AMSAT table in the main hall, and will give a
satellite-related presentation at 1100 local time on 17 July.
During these two days, WD9EWK will be on FM satellites and also
VO-52 for demonstrations (hamfest site is in grid DM35vg). More
information on the hamfest is available at:
http://www.arca-az.org/arca/main/convention.asp
After the hamfest, Patrick reports that he will hit the road for a few days.
Similar to what he did last year after the
Williams hamfest, except this year he
will venture further north into Utah. Patrick
will make a loop through that state,
then head back toward Arizona so he is home by the evening of 22 July. The
route through Utah yet has not been finalized yet.

Castor and Pollox Posed to Launch with STS-127
AMSAT News Service Bulletin 193.06
From AMSAT HQ SILVER SPRING, MD.
July 12, 2009
To All RADIO AMATEURS
BID: $ANS-193.06
Castor and Pollox, two satellites in the Atmospheric Neutral Density
Experiment
(ANDE) program are ready to fly with the launch of STS-127 from Kennedy Space
Center. The ANDE mission consists of two spherical spacecraft fitted with
retro-reflectors for satellite laser ranging (SLR). The constant and
well-determined cross section and surface properties of the ANDE spacecraft
provide an ideal set of objects for monitoring atmospheric drag and the
calibration of space surveillance network (SSN) assets both radar and optical.
Castor
Castor is a 19 inch diameter aluminum sphere with
a mass of 63 kg. It is as near
perfect sphere as possible given the constraints of cost and
manufacturability.
The sphere is split in half with e delrin disc. The hemispheres are also the
satellite antenna. For power, the satellite has 112 19AH lithium primary
cells.
This provides about 7000 watt-hours of power which has to last for the one
year
mission.
The satellite has several different types of sensors. There are two main
sensors, a Neutral particle wind and temperature spectrometer and an ion mass
spectrometer.
A group of college students designed and built a MEMS sensor payload to test
some commercial gyroscopes and a magnetometer. There are also six light
sensors
and six temperature sensors mounted in the satellite hemispheres.
Pollox
The Pollux satellite was originally to be a passive satellite with
retroreflectors for laser ranging. It has been
turned into a high school student
project involving several schools in the Fairfax County, Virginia area.
The satellite is powered by twenty-eight 19AH Lithium-ion cells configured to
provide 14 volts. The battery configuration uses the spare ANDE satellite
hardware.
The electronics is based on cubesat hardware developed at the Naval Research
Laboratory and Stensat Group LLC.
The communications board contains the transmitter and receiver. The
transmitter
operates at 2 meters and can put out up to 1 watt of signal. Power level is
adjustable. The transmitter can operate at 1200
baud AFSK and 9600 baud FSK. The
transmitter uses the AX.25 protocol. An experimental FX.25 protocol will be
tested that adds forward error correction capability to the AX.25 protocol and
still allows typical TNCs to decode the packets.
Both satellites will transmit on 145.825 MHz. Additional details about the
telemetry format, as well as the FX.25 and GMSK experiments can be found at

1. Upcoming School Contacts
An Amateur Radio on the International Space Station (ARISS) contact has been
scheduled for Euro Space Center, Air and Space
Day in Belgium on Sunday, July 12
at 14:08 UTC via telebridge station WH6PN in Hawaii.
2. Inukjuak Space Camp Participates in ARISS Contact
On Wednesday, July 1, Inukjuak Space Camp in Kuujjuaq Quebec, Canada
participated in an Amateur Radio on the International Space Station (ARISS)
contact via telebridge station W6SRJ in California. The event took place on
Canada Day with Canadian Space Agency astronaut Robert Thirsk, VA3CSA. Thirsk
answered 20 questions put to him by the students. Makivik Corporation, a
non-profit organization that promotes economic growth of Inuit businesses,
sponsored the event.
3. ARISS Contact with New York Scouts
On Friday, July 3, an Amateur Radio on the International Space Station (ARISS)
contact was held with Baiting Hollow Scout Camp (BHSC) in Calverton, New York.
The contact was made possible through telebridge station WH6PN in Hawaii. Ten
scouts asked 18 questions of JAXA astronaut Koichi Wakata, KC5ZTA. The event
was held as part of the camp?s theme for 2009, ?Final Frontier,? and a variety
of other activities have been planned throughout
the summer dealing with aspects
of manned space flight.
4. Astronaut Training Status
On Thursday, July 2, four licensed astronauts took part in Amateur Radio on
the
International Space Station (ARISS) simulated
contacts. Satoshi Furukawa, KE5DAW
and Timothy J. Creamer, KC5WKI had contacts with
Ottawa area students in Canada.
Doug Wheelock, KF5BOC and Soichi Noguchi, KD5TVP participated in contacts with
students visiting the Challenger Learning Center
in Indianapolis, Indiana. These
training sessions are terrestrial-based amateur radio contacts using ARISS
equivalent equipment.

Hi John,
You might consider putting a short tripod on the roof itself. That's
what I did. 2-story house, and too many trees adjacent to the house to
put up any sort of tower (and not counting the inevitable XYL objections).
Here's what I did: http://home.wavecable.com/~ko6th/IMG_0141b6.jpg It
basically just sits on the roof, and is kept from sliding by being anchored to
a vent pipe. The base is 8' wide, with a 4' "T" piece going up to the pipe.
The vertical part is about 6' tall, which gives the tail of the 70cm beam just
enough clearance from the roof for overhead passes. Never had a problem with
stability.
Good luck,
Greg KO6TH

John & Greg,
In addition to bad propagation, Larry and I have been on travel and Field
Day over the last month. I will be there this Sunday, but Larry may still be
on travel. See you on 14.282!

To: Lurking Old Timers
I need three consecutive pages and front matter from one of the
W6PAJ orbit calendars published in early 1970's for a professional
paper. (If you don't know what I'm referring to please just ignore this
note). Scanned or Xerox copy via US mail is fine. Please reply direct,
not via AMSAT-BB. Thanks!
