This may be old news to many but perhaps will save a few hours of frustration
for newcomers.
In my prior post about HRD Sat Tracking slowness with my Windows Vista
computer, I reported there that ST was working very slowly with my Lenovo
desktop running Windows Vista, but that it ran at normal speed with a laptop
running Windows XP. However, the frequencies were not tracking properly -- the
transmit frequency would "stick" as the receive frequency on my IC-7000.
It seems there is a hardware cause for this issue. After I gave up trying to
get HRD Sat Tracking to work with the laptop, I downloaded SatPC32, another
program that automatically sets transmit and receive frequency to account for
doppler. The same "sticking" problem occurred with that program.
The ReadMe(Icom) in SatPC32 provides what appears to be an explanation for
this issue:
**************************
With ICOM half duplex transceivers (IC-706MKIIG, IC-7000) hardware
handshaking must be installed to suspend computer control while the radio
is transmitting. Frequency changes are theoretically possible while the radio
is transmitting, but frequency errors will occur, i.e., the frequencies
of VFO A and VFO B will be exchanged.
Unfortunately there is no way to check the PTT state of the radio via
the CAT software. Therefore hardware handshaking is needed to prevent
writing to the radio while it is transmitting. On the radio side pin 7
of the ACC socket can be used for this purpose. The voltage at this pin
is approximately + 8.0 V while the radio is in RX mode. In TX mode the
voltage at pin 7 drops to 0.
Pin 7 of the ACC socket must be connected with the CTS pin of the
serial port on the PC side (pin 8 of the 9-pin, pin 5 of the 25-pin
RS232 cable connector). I have connected these pins via a diode
and a 5K resistor, see Acc_Com.jpg in this sub folder.
IT GOES WITHOUT SAYING THAT EVERYONE INSTALLS THIS LINE AT HIS OWN RISK!
When the radio pulls down the voltage at pin 7 to 0, it signals the PC
not to send data. As soon as the radio is back in RX mode the frequencies
are updated by the program.
ATTENTION! There must be NO bridge between pins 7 and 8 of the 9-pin
(5 and 4 of the 25-pin) cable connector at the PC side! Otherwise the
voltage at Pin 8 (rsp.Pin 5) and therefore also at Pin 7 of the ACC
socket will be pulled down and the radio will be switched into transmit
mode. The sketches in the Icom sub folder provide this bridge. If it is
built in, please, remove it.
The 25-pin Connector at the ICOM CT-17 also provides a bridge between
pins 4 and 5 and other pins. The CTS pin of the cable connector at the
PC side must be connected only to Pin 7 of the ACC socket.
*************************
Thus, as I appreciate this, a standard ICOM CT-17 CAT cable will not work
properly with SatPC32, and presumably not with HRD Sat Tracking either.
Can anyone confirm this? Does anyone sell modified CT-17 cables that will do
the job?

Well, I have never used rss feeds nor even how you get
them...therefore, I do not miss whatever they are! (HINT: maybe need
a tutorial, here?)
Your example does give nice links to summary info for each satellite,
but the status links are empty. Would I guess that current info on
what modes are activated show up in them? For active satellite
operators that would have the most value.
I guess I'm neutral on the idea. The history of Amsat's website and
information system is that it is inconsistent (ANS an Journal have
been great, though). Guru's come and it's great; they burn out and
leave and it's not. I realise this is a pretty brutal evaluation,
but one should examine their commitment level before starting. I
think this is why Amsat-NA volunteers are thoroughly vetted. Big
reponsibility to maintain what you start!
But we welcome your enthusiasm!!!

I havent tried every product out there but I'll share what I've experienced.
AES will sell the Mirage preamps (KP1440), but I cant recommend those. I
recently bought one for 70cm and was very unhappy with it. Gain was poor as
was immunity from interference (i.e. my 2M uplink).
The Ramsey PR40 amps are a fun kit to build and you cant go wrong for about
the $20 price tag. Takes an hour to build but don't be surprised if you take 4
times that working out and assembling a case, housing, connectors, pigtail
leads, etc. Still, its cheap and fun and a fantastic option for portable or
handheld use. But this, like many other RX amps has no sense of humor when it
comes to accidentally transmitting through it. It only takes one bump of the
PTT to fry the transistor. Happily its a quick replacement and a $2 part. I
built one and keep it as a backup.
My everyday preamp is the ARR SP432VDG. Its a 25 watt switched model for
indoor use at about $120. There is a $90 RX only version with the same
vulnerability as the Ramsey and other RX only units. I know mast mounted
should be a lot better but I opted for indoor use due to the lower cost and
couldn't be more pleased. Lots of gain (9+ s units vs 7 on the Ramsey and
Mirage) and no de-sense or interference from my uplink 3 ft away running 50
watts. The other nice thing is that its small enough that I can bring it
outside with the Arrow/Elk and easily run it on a small 12 V source (pack of 8
AAA batteries). One thing to watch out for on GASFet preamps is you should
never swap connectors or antennas when they are energized. I popped my first
one (wondering how since I only had 5 watts) and after a long talk with ARR,
agreed that this how I may have done it. ARR customer service was also very
responsive and personable (its a small company).

Hello Bill,
the SatPC32.Exe and SatPC32ISS.Exe files that come with the 12.8 setup file
require the hardware handshaking I have described in the Readme(Icom) text
(the "normal" SatPC32 only with the semi duplex radios IC-706MKIIG and
IC-7000 when used as single radio for satellite operation, SatPC32ISS with
the IC-910H for "inband" operation in non-satellite mode).
Meanwhile this hardware handshaking is no longer necessary. Some time ago I
have uploaded patch files on my website www.dk1tb.de (English page
"Downloads", sect. 5 "Patches"). With the IC-910H and IC-7000 the PTT status
is now checked via the software (CAT command hex. 1C. I didn't know that
command when I released 12.8. My manual doesn't mention it).
The IC-706MKGII doesn't provide such command, but Tony Monteiro, AA2TX,
found a solution also for that radio and told me the trick - many thanks to
him. So, also this radio does no longer require the extra line between the
radio's
ACC jacket and the PC's serial port.
On my website I have described how to use the patch files.
73s, Erich, DK1TB

Hey everyone,
At 21:33 UTC today (12 April), G1WPR answered my "CQ DX" on AO-7/Mode B. I was
sending CW with the straight key I picked up for Straight Key Night on AO-51,
and Terry called me in SSB - so we completed a cross-mode QSO of more than a
minute with a few exchanges. I am thrilled!
I used a Yaesu FT-857D for TX and ?a Yaesu FT-817ND for RX (both used radios),
and a Diamond MX-72H duplexer to connect them to my dual-band Elk log
periodic, which I hand-hold and manually track the satellites. I mention all
of that because I have learned that (1) one doesn't absolutely need all the
bells and whistles to enjoy any - and all - of the amateur satellites
currently in operation, and (2) the Elk rocks!
That being said, I will confess that adding computer Doppler control has made
a huge difference here with the linear satellites. I was using Simon's HRD
Satellite Tracker on that pass, but I also have SatPC 32 and Orbitron set up
and successfully Doppler tuning here. It's nice to test and experiment with
all of them.
I want to sincerely thank everyone who has provided insight, guidance and
encouragement over the past 10 months, and I especially want to thank Joe,
K3SZH, who has told his longtime AO-7 friends in western Europe that there
might be a CW signal from EM84 down the passband.?
Happy Easter, and 73 to all,
Tim - N3TL
Athens, Ga. - EM84ha?

Some weeks back someone asked where they could obtain the manual for the
old Kenpro KR-5400/KR-5600 AZ/EL rotors. These are the predecessors of
the Yeasu 5400 rotors. There is a lot of similarity since Yaesu bought
out Kenpro. The person asking never responded when I replied that I had
made him a copy of the manual. It has been sitting on my desk, taking
up needed space, so I will send it to the first person having the KR
series rotors asking for it with a complete mailing address. If none
then it will go to someone else. If none, it will be tossed out.

Hi Jerry,
I cannot say enough good things about the preamps AND the PEOPLE at Advance
Receiver Research! They are always personable, quick to ship/repair, and
their products are awesome.
I have around 5 of their preamps around the shack right now (okay, four are at
the antennas where they belong!). It makes the difference between hearing
and not hearing.
In the last few weeks I finally added a 2M mast-mount model at the antenna. I
keep kicking myself for not doing it years ago...I can't believe how much
better I can hear AO-7 now.
Suggestion---I have found that over the years I tend to "mess around" rather
than get what I really want to begin with. In that vein---I don't think you
will never regret getting the 160 Watt mast mounted versions:
http://www.advancedreceiver.com/page10.html
Models relevant to 2M and 70 cm:
MSP144VDG-160
MSP432VDG-160
Yes, they are an investment of hard earned ca$h. But they're a GREAT
investment, if you want to hear...
73,
Mark N8MH
