Or working AO-51 with a pair of HTs and rubber ducks (yes, I have
done this!).  Hardly extraordinary. :)

Okay, I am starting to build my station after playing around with the
portable. So far I have acquired an IC-910 with 1.2G, power supply, G-5500
AZ/EL rotor, M2 2MCP14 and 436CP30 antennas. To finish I have the following
questions.

1. What radio, rotor and tracking software are you using and why? (I am
using Orbitron right now)

2. What interface are you using for an IC-910H and why?

3. What interface are you using for your G-5500 rotor and why?

4. What are you using for the radio side for 2.4G?

5. What antenna are you using for 1.2G?

6. What antenna are you using for 2.4G?

Thank you in advance for your time and help.

Hey Mike you're on a roll!? What I have done with the 2.4 side is the
following.?I picked up a fairly cheap 2 meter xcvr, a TS-700A ($200)?I
disabled the transmitter, it is now the designated S band Rx.? The reason- In
the heat of battle (stupidity) I realized I could easily transmit into my
downconverter.? I could probably do it more that once!? Call it cheap
insurance.? There are several 2.4 downconverters out there, ?I have a couple
from K5GNA, very reasonable at $120.? He recrystals? and "tweeks" them.? I do
not know if he is still selling them.? With no HEO there is little demand.?
Commercial ones are available, SSB, KEPS, downeast,?and maybe more ($$).?
I?use a ?three foot primestar dish with 5 turn helix feed for rx.? When AO40
(sobsob) was up, I used a 4 foot primestar.?.? ?Overkill for AO51- I'm
thinking next HEO.? A 18 inch direct tv dish would work on 2.4.? On 1.2ghz. tx
?I use a 16 turn helix.?? I do not have computer control (yet) so I really
can't address that !
issue

This is the way I do it.? Others may differ and maybe be better, that's what
makes this so fascinating.

Hi Mike,

Well I am sure that my set-up is very similar to a lot of other op's on
this board but here goes!

1) Radio is an Icom 910HX, Rotator is the G5500 and SatPC32 to do the
tracking!

Why SatPC32? Because its a dedicated program that does exactly what it
says on the tin (unlike Ham Radio Deluxe which is a jack of all trades
and master of none, IMHO, and still has Icom issues), has  great
customer service, all sale proceeds go to AMSAT and a lot of people on
the BB use it so there is no shortage of help when needed (Thanks to
Alan, WA4SCA!)

2) Interface between 910 and PC is a CI-V clone cable available on e-bay
for less than $20

3) Interface between PC and G5500 is an LVB Tracker - why?
Again, profits to AMSAT, super after sales service, it works and works
well and it really looks nice in my shack! If you have the money then
sure, go buy the Yeasu alternative but you can buy an awful lot of other
goodies with the change that an LVB will give you!

4) Because I do not have the "proper" Icom CI-V unit, I can only control
one radio at a time with SatPC32 so when AO-51 is in Mode S, I use the
910 for the receive side allowing SatPC 32 to calculate the doppler. For
transmitting, say on 2m (When in Mode V/S) I use my Icom 706MKIIG and
just leave the transmit frequency alone - works like a charm. When AO-51
is in Mode L/S then SatPC32 can do everything I need through the 910.
The 706 is only used when Mode S is on as it ties up the 2m band.

5) 1.2Ghz antenna is the helical antenna built and sold by Bob, W7LRD -
its solid, performs excellently, Bob is on hand in the event of problems
and he donates 20% of each sale to AMSAT.

6) Currently I have a BBQ dish feeding a downconverter but I spoke to
Bob (W7LRD) about ordering a 2.4ghz helical antenna which will replace
the BBQ dish as its rather heavy and cumbersome. but again, it works and
as I paid $15 for it and the downconverter, I really can't complain. But
with Dayton next week, I am saving my pennies so I will order the
antenna when I get back.

Now one thing that I did not see on your list was pre-amps!

Again in my opinion, you really can not do without them. A lot of
people will steer you towards SSB Electronics or ARR as sources and yes,
they are great pre-amps but if you are putting a station together and
you have the 910 have a think about the much maligned Icom pre-amps -
yes, I know they do not publish noise figures and everyone says they are
crap etc, etc but you can not blow them up by transmitting through them,
they do not need a separate DC feed, they are readily available and they
do work. Last evening I had an SO-50 15 degree pass out over the
Atlantic and I worked a station and then turned the pre-amp off
afterwards and I could not hear him. That pre-amp made the difference
between a successful QSO or not one at all.

Now I know that people reading this will say, "hang on, 15 degrees, why
the big problem?" but let me explain that currently I live in an HOA
community that does not like you painting the front door or changing the
brand of toilet tissue without having written permission from the Board
of very old people with far too much time on their hands. So my antennas
are probably no more than 6 feet off of the ground within the confines
of a pool cage. Whilst that sounds very restrictive, and to an extent it
is, I work all of the analogue birds, the ISS and I get pictures from
the weather sats. Last month I worked 171 stations. So it can be done.

I hope that some of the above is of use, if you want any pictures of
what I have here then please e-mail me off the BB and I would be happy
to send you some.

73's for now

David

Hi Mike,

Glad to learn of your developing satellite station!  You are doing it
"right"...

One very important item missing from your list:  low noise mast
mounted preamps!  I really love my Advanced Receiver Research 160W
mast mounted preamps for 2M and 70cm.

I'll take a shot at some of your questions, responses below:

questions.

1. What radio, rotor and tracking software are you using and why? (I am
using Orbitron right now)

SatPC32. It does it all, and does it remarkably well.  There is a
cost to license, but ALL of the money goes to AMSAT-NA (if you puchase
there--THANKS Erich DK1TB!)

2. What interface are you using for an IC-910H and why?

Not applicable, have a TS-2000X.

3. What interface are you using for your G-5500 rotor and why?

The AMSAT LVB Tracker, because of cost, packaging, ease of use,
proceeds go to AMSAT-NA (Thanks Howard G6LVB, Mike WB8CXO, and Gould
WA4SXM!)

4. What are you using for the radio side for 2.4G?

Either the TS-2000X or the TS-790A, with a self modified
Transystem downconverter to 2M

5. What antenna are you using for 1.2G?

20-turn WIMO helix

6. What antenna are you using for 2.4G?

A 32" DH satellite dish with G3RUH patch feed, DEM preamp


Thank you in advance for your time and help.

Mike


I hope the information is helpful---and don't forget the preamps :)

Mark,


>>I really love my Advanced Receiver Research 160W mast mounted preamps for
2M and 70cm.

Agreed about mast mount preamps in general, and the ARRs do a good job.
However, be certain to double check the sealant around the screws which hold
the top on.  If you don't, and you have driving rain, they can/will leak and
fill up the catch basin inside.  Happened to me.  Personally, I prefer the
SSB units which are a bit pricier, but have a better design WRT
waterproofing, and the adjustable gain is a convenient feature.  My
relatively new ARR is now properly sealed, has drain holes, and functions as
a backup and loaner.

See you at Dayton!

Alan
