Surplus KCT



I have at my QTH a Kansas City Tracker board with a printed manual and a
copy of the KCT.ZIP file.  The owner of the board, George-WA5KBH, would like
to find it a home.  To acquire it contact me (Al-N7EQF) directly by email.
The cost of acquiring the item is to  pay for the shipping cost (flat rate
priority mail envelope), commit a donation to AMSAT and promise not to ask
me any questions concerning how to install, configure, or operate it (I do
not know).  The board is un-tested and may or may not work, no known reason
to suspect it's condition.



Thanks - Al - N7EQF

Since it has been a while since these have been up on the list, I want to
remind folks that this requires an early early early generation slot,
called an ISA slot.  The drivers for the card are STRICTLY DOS 6.2 and
earlier interrupt handlers and are zero likely to work on a modern windows
machine.

If you have an old machine with ISA slots, running DOS,  this board was one
of the engineering marvels of its time and should still work beautifully on
Yaesu rotators today. You will need Quiktrak or IT to run it (again, DOS
computer programs).

WISP is another Windows program that controlled the Kansas City Tracker ISA
based card very nicely, if you want to use it in a Windows 95/98
environment.

Thanks Dave and everyone else who responded, both personally and on the
board.  To comment on a couple of comments: I certainly expect to hook up
computer control of the doppler comp etc, but was trying to do it manually
at first just to understand better.  Re my problems inside:  The shingles
on the house are pretty new so are not embedded with guck.  However, I
expected them to be pretty neutral.  Not so.  But anyway, I've given up
having antennas in my attic, and I'm outside now exclusively.  Re power,
using CW to match up.  Ok, I'll try my full power out, and CW.  Thanks for
the ideas.  Re other sats, beam, etc:  Good ideas for sure; I wanted to
eliminate variables, and since I can't mess up pointing with an omni, and I
have received ARRISat easily, I figured ARRISat involved the fewest
variables.  But I'll try the other stuff too.

Thanks again to everyone!  I'll let you know how I make out.  In the
meantime, I'd like to hear from anyone who has been successful with an omni
or Lindenblad with 50W uplink.

I have my original PacardBell P100 desktop with win95 which has been
gathering dust on a shelf.  It has ISA slots and parallel port which
would probably be ideal for running KC Tracker.  I offer it for sale
for $50-OBO (as-is with keyboard and mouse but no monitor) plus
shipping (best to go parcel-post from my zip 99635).

I kept it since these old machines have little or no residual value
in case I wanted to run some old legacy sw.  But I also have a IBM
P90 Thinkpad with win95 for this purpose (I also use it for packet
and a DOS cw keyboard program).

I still use my KCT card with SatPS32 under windows XP. I bought an updated
ISA slot motherboard for somewhat more then I would of paid for a comparable
performance Mobo for the same money. That was about 3 years ago. All is
still working well. I tried to upgrade to Win7 a year ago but gave up
because of some other issues I don't quite remember other than the KCT. This
is my oldest computer I now own, but still works well running APRS with WX,
and to track sats with...

All,

Does anyone have any recommendations on high quality mast-mounted preamps
for UHF?  We're using the Icom AG-35 and not happy with the noise figure.
 We're going to try an adjustment described here
http://www.eham.net/reviews/detail/6116.

We are looking at the amps from ARR and SSB.  Any other recommendations?

Thanks,

The difficulty with mast mounted preamplifiers is that they have to be
selected for a
specific electromagnetic environment.
If your environment is "hot" with a lot of ham activity, local pagers
and FAA stations,
the preamp may not be able to handle all of the RF, unless it is
suitably narrow banded.

Some preamplifiers are broadband and some are narrow band, where you
will be operating.
If your environment is quiet, most any preamplifer will work well.
If your RF environment is NOT quiet, you have to limit the preamp RF
pass band for your activity.
Otherwise too much RF gets into it and raises the noise floor, reducing
the S/N

Last time I tested a ICOM 2M preamp, it performed well, less than 1 dB
NF with pro test gear.

What does your RF environment look like ?

I also have an old Motherboard with an ISA slot.  Just the motherboard,
processor (1ghz, I think), and memory.  I do not have anything that needs
the ISA slot anymore, so it's up for grabs.  No reasonable offer will be
refused.  My wife insists...  :-)

Hi Jamie

In a separate email I have sent to you an article that I write for Radio
Rivista 9/1993 describing with schematic diagrams and mechanical
drawings my low noise GaAsFET high dinamic range  and high
selectivity cavity preamplifier for 435 MHz with NF=0,43 dB and
gain G = 20 dB

I am using it with great success in my environment area in the bay of
Naples wich is "hot" with a lot of ham activity, local pagers  and FAA
stations.

By the way it require a lot of mechanical work but for best performance
it must be tuned for the lowest Noise Figure using only a very simple
diode noise generator that was described in the article.

Unfortunately building low noise preamplifiers and tuning instruments
by yourself in novadays seems to become a RF  "endangered species"

Have fun.

Hi Jaime

I built this preamplifier as Domenico described in his article. I am using
it with a
great success too. My environment area is very hot also; I live into the
city wish has a
lot of buildings, Ham activity, broadcastings, repeaters and other stations.

Before I used it; I had the T/V channel interference on the downlink of
SO-50 and AO-27.
When I began to use the preamplifier the interference disappeared.

It is a great design!

73!
