Here's a partial op sked for tonight's and tomorrow's passes and grids.
I'm cutting it short to make the first pass on the list. More info
later.
Planned
VO52 - 15/0245Z - DL26
FO29 - 15/1024Z - DL25 or DL35 (or both!) - we'll probably be in DL35
for an hour or less
AO51 - 15/1048Z - DL35 or
Hello Dave,
My Rohn towers use a flat top section, I wrap in a 3X loops ~ 12-15' of
a flexible coax as the rotator loop.
The loops are loosely layed in on the flat top plate.
One end anchored with Tye wraps to the main tower and the other end
anchored to the rotating mast,
with another single l
Jerry,
I ran the same setup. You are good to go, no problem.

I am considering placing a 432 preamp (ARR P432VDG) in the 432 line
coming from the splitter on my Arrow. Do I have a danger in the 2M
signal overloading this preamp back through the 432 antenna on the
Arrow? Hope I've composed this question so that it could be understood.
Tnx for any ideas.

Hi group- I'm installing my 2MCP22 and 436CP42 U/G antennas and find that
the coax is hanging up on the Rohn tower sides near my G-5500 rotator plate.
How are folks keeping the coax away from the tower sides and hanging up?
Springs? Cable ties?
I have hung it up twice and stalled the AZ/EL. I
Ramon (XE1KK) and myself (LU6QI) made a QSO on AO7 in SSB Mode B at
11.12 UTC on March 14, 2011 during the orbit #66247. The distance
between Ramon’s location (EK09JI) and mine (FF66TQ) is 6816.7 km.

All,
First of all I wanted to thank the HAM community all over the world for
supporting our project, your support has been incredible and we really
value. Today, after a few months of initial operations, we started one of
the most exciting phases of our project by separating both of our girls so
Bring the parts, cables plus connectors to the store when shopping. The
biggest problem is cable bend radius.

Joe speaks wisdom when he says get a bigger one that you think you need.
I have a whole pile of those boxes in the garage because I thought they
were "big enough" for the project I had intended to build in them.

Check the electrical departments at Home Depot and Lowes for inexpensive
plastic boxes made by Carlton. These are fully weatherproof boxes
without any knockouts that are excellent for weatherproofing
preamplifiers. You will probably need some type N bulkheads that have a

Hi Enso,
The OZ7SAT system is set to use 1268.705 MHz for the uplink. The actual
frequency will vary a little bit due to temperature variations (the radio
and transverter is located outdoors) but this does not seem to have a big
impact on the uplink.
We have adjusted the modulation so the resultin
Hi,
Today at about 15:00 pm i had a good pass of AO-51 but as usual i could'nt get
in.
I've tried during the whole pass to tx on the uplink frequencies moving a bit
up and down but nothing to do, i did not get any response.
I have tried with two TNC with a TINY-2 and with a TNC3S but had the same

It's possible to happen on 2 meters via satellite too.

Back in the late 70's I was working AO7 mostly on Mode A, two radios,same
stacked 11's,and tri-bander for HF. had few passes that were below my
horizon,no problem for F2 downlink, but was able to get into it on 2m, with

Hi all,
Apologies for this very late notification.

modern day life.
It is also a great opportunity to fly the flag for
Paul,
The main advantage of a preamp is increasing your sensitivity by
lowering the noise figure of your receiving system. You lose some of
that by locating the preamp in the shack. Any coax loss between the
preamp and antenna adds directly to the overall NF: 80-foot of
LMR-400 is 1.2 dB l

I couldn't hear AO27 well at all. The satellite only got up to 6 degrees
at my QTH, but I've worked that satellite a lot of times at lower
elevations, so I really couldn't figure out why I had such difficulty.
