Hi all,
I would like to clarify on the Delfi-C3 data server settings. When changing
the IP in RASCAL, please only change the PRIMARY IP address, and leave the
secondary as-is. This prevents the server from receiving all packets in
duplicate, slowing down the processing of telemetry.
Our apologies for the possible confusion.

Lots of good replies to my question. A little background on my experience
with remoting. I first tried remoting about 10 years ago. At that time my
100 watt system was composed of a Kenwood TS-2000, a Steppir 4L beam,
several wire antennas for the low bands, and an Oscar class satellite
antenna system. I used TXManager to control the radio on HF and the local
repeaters, WiSP for sat work, and SKYPE for the audio. I worked HF, FM sats,
and local repeaters. When I retired from my fulltime job that required a lot
of travel I had no need for a remote system anymore. This time around I'm
living in three different locations. The one in NJ near Philadelphia is the
main station where the HF and sat antennas are currently located. At my
shore condo also in NJ, there is zero places to put up antennas. At my
recently acquired Florida waterfront home I plan on putting up a small
tower, and a vertical grounded into saltwater. I'm also acquiring the
antennas, rotors, etc to put up a smaller yet, sat antenna system.
Right now I'm remoting a 600 watt K3 system with one antenna using
Remoterig.com hardware. I use TeamSpeak to 'see' my panadapter s/w and to
control the KPA/KAT500 600 watt tuner/amp system. I used this setup every
day while in Florida for several months setting up the new QTH. I also use
this setup while down the shore at my property there. I really missed
working the sats when I was in Florida for three months, so I started to
think about remoting my sat station also. It looks like I will be once again
going to be using SKYPE for the audio, same as I did ten years ago. The lack
of fullduplex audio seems to be an issue with the SSB birds, last time I did
this I just worked the FM birds, thanks Dave PVH for the SKYPE info to try
on the linear bird's. Thanks to Erich for the hidden tx/rx controls, and the
added rotor info in his SatPC s/w. I was also thinking that it might be a
bit easier to just put a sat station up in Florida, but then I thought it's
a much better shot into EU from NJ then from FL so even if I got OTA from
Florida I still might like to use NJ as a alternate TX site. Lots to think
about, what a great hobby for a retired person :-) At QRZ I'm kinda tracking
what I'm doing, along with some pictures, just goto kb2m.....

Jeff,
You can remotely switch the radio between RX and TX (PTT). In the
SatPC32 main window double click on the Statusbar at the bottom of the
window. Three TX/RX "buttons" will appear in the corners of the map. If the
remote link fails while the radio is in TX the program will automatically
switch it back to RX after a selectable period (menu "Options"). Default is
60 seconds. If you set the value to 0 the functions is disabled.

Finally did some PSAT tests with 1/4 wave on car roof and TH-D72 Kenwood
radio.
* On a 60 deg pass I heard 25 packets decoded one at 5 bars.
* On 21 degree pass heard 5 packets but none above 1 bar.
* On 40 degree pass heard 37 packets decoded 5 when they hit 5 bars. Also
got in with 5W.
* on 40 deg pass (in Annapolis) heard a single 5 bar packet and no decode.
NOTICE, the first three were at the beach with no real planning as to
building obstructions. But apparently the noise open squelch was S0. But
in Annapolis, after hearing nothing (1 packet) I opened the squelch to see a
full 3 bars of noise. Remember, the radio ALWAYS shows ZERO S units until
the squelch actually opens, so the presence of even S9 broadband noise will
show nothing and HEAR nothing unless you open the squelch manually!
The Baghigawatt area defense radar on 149 MHz in the DC area was operating
at the time. Again, shows the value of having any SATGATE OMNI antnenna on
the ground well below horizon (and only able to see sky above 30 deg)...
P.S. On this 19" magmount whip, the 435.350 PSK31 came in FINE! Remember
this is a 3/4 wave vertical on UHF. So to pick up the needed 3dB more on
VHF, the next tests should use a 3/4 wave at VHF or about 58 inches...
Much more testing needed. de WB4aPR, Bob
------------------------ original message ----------------------
Some EZNEC models:
1/4 wave with radials: -2 at 30 and -6 at 60 ==> Basically a dipole
pattern
3/4 wave with radials: +2 at 30 and -1 at 60 ==> 4 to 5 dB better, 2 dBi
max
3/4 wave w 3' gndpln: +3 at 30 and +1 at 60 ==> 5 to 7 dB better, 3.3 dBi
max
3/4 wave w 6' gndpln: +2 at 30 and +3 at 70 ==> 4 to 9 dB better, 5.5 dBi
max
3/4 wave w 9' gndpln: +3 at 30 and +3 at 65 ==> 5 to 9 dB better,5.3 dBi
max
3/4 wave perfect gnd: +3 at 30 and +3 at 68 ==> 5 to 9 dB better, 6.9 dBi
max
Even the 3/4 with just the four 19" radials gives a huge 4 to 5 dB
improvement over a classic ground plane for omni satellite SATgate work.
Also, this antenna does not need to be high. Just see sky above 30 deg. In
fact, is better to be low to reduce terrestrial QRM.
Notice too that the Lilenblatt, eggbeaters, and all other "omni"s that try
to keep their gain down on the horizon, are equally as poor as the 1/4 wave
vertical at these higher elevations. This is OK for strong satellits like
the ISS with 5 to 10 watts, but abisimal when all that gain on the horizon
is completely wasted when you cannot hear the satellite anyway because it is
6 to 10 dB farther away! The result is these "omni's" give up the 4 to 9 dB
at higher elevations where the satellite is much stronger.
See the Omni SATGATE page:
http://aprs.org/aprs-satellite-igate-antennas.html
Summary: The 3/4 wave vertical should make it so you CAN hear weak LEO
satellites 5 to
9 dB better when they are closer and does this by giving up on hearing
them when they are so far away you can't hear them anyway!

> One question,what constitutes a large ground plane?

Good question. Most people think that four 1/4 wave radials make a ground
plane. But if you model a 1/4 wave vertical over 1/4 wave radials, all you
get is the exact pattern of a DIPOLE. The radials are just providing a
"groundplane" to complete the electrical part of the antenna and give a good
match. They do not affect the pattern at all.
I modeled verticals over 6' or larger ground planes and only found that you
get the added "reflection" gain when the ground plane starts getting that
big or more. I wish I had time to use EZNEC to show the added gain
(skyward) versus the size of the ground plane. And how "radials" (above
actual ground) have nothing to do with the "pattern".
SO, the bigger the better. It should be worth 2 to 3 dB if you could make
it very large...
This is the page in question:

Message-ID: <000001d0beeb$d96ce9d0$8c46bd70$@xxxxx.xxx>
Content-Type: text/plain; charset="us-ascii"
Hi,
People sometimes post time-sensitive messages to AMSAT-BB and SAREX.
Examples are last minute grid
activations, unexpected satellite mode commands, requests for critical
telemetry after a launch, etc.
These normally go through promptly, but occasionally get held for two
primary reasons:
While AMSAT-BB and SAREX are both open lists, that means they are open for
membership. In order to
post to the list, it normally must be from the same account you originally
registered. For instance,
if you registered from your home account, and post from your office account,
it will normally be held
for release by a moderator. Likewise, some people have all their email
forwarded to a single account
from which they reply. We can easily create a filter to pass the second
address, but that is not
automatically done on the first posting, and does require moderator action.
Both mailing lists receive literally dozens of pieces of spam for each
legitimate message. As part of
the filtering process, emails larger than 40-50kB are blocked. This usually
happens to legitimate
email when someone attempts to attach a large file, or replies to a long
message without trimming.
These also require moderator intervention, and are normally not approved but
bounced back to the
originator for adjustment. Also, there is a limit to the number of addresses
before an email is held
as potential spam. I have seen legitimate email sent to 20+ addresses.
We have a team of volunteer moderators, but they are not available 24/7. The
result is that a message
sent in the evening or on a holiday, US time, may well be held for 10-12
hours before being released.
So, if it absolutely, positively needs to be distributed promptly:
1. Post from the same account you registered for, or one which from past
experience you know has been
flagged as acceptable.
2. Post a message less than 40 kB, with no attachments which will always be
stopped. (Pictures should
be included by a link.)
3. Send it to AMSAT-BB, SAREX, and a few other addresses a most. If you must
send to a large
distribution list, send to them, and another copy to the AMSAT lists.
4. Consider also posting to the AMSAT Twitter and Facebook accounts. There
is overlap in membership,
though at present it is far from 100%.

My packet setup gets digipeated instantly on terrestrial APRS networks, and
works fine with ARISS, but even with overhead passes on NO-44 and NO-84,
when I copy the birds well, I can't manage to get an APRS packet digipeated.
Even if I crank the power up to 50 watts, using the M2 LEOpack antennas,
those birds simply are deaf to me. I'm sending to CQ via ARISS, as my
reading of the online docs seems to indicate that is appropriate. I've also
tried CQ via PCSAT-1 and CQ via PSAT (for NO-84) but still no joy. I've also
played with TX delay. Nothing works. What am I doing wrong??--?Mark D.

Mark,
If you are trying to digipeat through NO-44, you will need to use
W3ADO-1 as the path. For NO-84, it won't digipeat anything sent
via PSAT, but you can use ARISS or APRSAT for the path. I have
not used NO-44 in a while, but when it is getting enough power
from its solar panels it does work with W3ADO-1. NO-84 is actually
a good APRS digipeater, even though not many stations are picked
up by the Internet gateways. It is possible that the gateways that
work fine with the ISS and its stronger signals just don't do as well
with the weaker signals from NO-84. With my TH-D72A and Elk, I
hear NO-84 well, and it seems to hear me OK once it is up a few
degrees above the horizon during its passes.
Hope to see/hear you soon on NO-84. I have logged one packet
QSO on that satellite, and will try for more. I also want to try the
10m/70cm PSK31 transponder, but for now my TH-D72A and Elk
antenna is able to use NO-84's packet digipeater well.
Good luck, and 73!

I have exactly the same problem. I can hear NO-84 and some of the
packets get out on the Igates, but I have never been able to get my own
transmissions recognized by NO-84. I use 25 watts into an eggbeater and
CQ via ARISS. NO-84 just ignores me, even on high angle passes. (For the
record, getting into ISS is no problem for me with my set-up.)
I'd love to hear how some others get in. I suspect they are using
trackable yagis.

Steve,
I'm using a "trackable Elk" antenna when I work NO-84. OK, I am
holding the antenna and pointing it at the satellite, twisting as needed
to keep up with what the satellite is doing in orbit. As I mentioned in
my earlier post, I am using a TH-D72A HT - just 5 watts. What path
(UNPROTO) are you using with NO-84? PSAT doesn't work, but
ARISS or APRSAT will work. I've used both of those successfully.
Remember that NO-84 transmits in the millwatt range, where ISS
has many times more transmitter power for packet. I think this is also
where many of the gateways are having difficulties with NO-84 - it
just isn't as strong as the ISS.
73!
