D-ATV Update from W6HHC
D-ATV News Update from W6HHC
Robbie-KB6CJZ and I teamed up to test our first
DATV station (DVB-S) over the long Labor Day
week-end (September 7 for those outside U.S.).
We then worked together to publish another DATV
article for the local OCARC newsletter to report
initial testing results of this station we had planned.
The title of the article is:
"TechTalk #77 – DATV Testing Report – Part 1”
The article can be found at either:

I hope that some of your readers may find this
article useful. Special thanks to Stefan Reimann
DG8FAC of SR-Systems in Germany for quickly
and patiently answering my many many questions.

Oat Mtn. 434 MHz Signals Wane
Some of the ATVers on Oat Mtn. have seen their 434 MHz
signals deteriorate and are not sure what is happening.
I am not as technically minded as others but we might want
to consider that in the past there were at leasttwo times
that Mike Collis, WA6SVT told us that he rotated the
community 70 cm antenna on Oat to favor an areato give
the ATVers a better shot at the repeater.
Mike said that moving the antenna wouldn't affect the other
services using the mountain top community or shared antenna
and most likely they wouldn't even notice.
Maybe someone gotpermission to turn the antenna back
to it's original position. Acheck with the siteownercould
shed some light on the problem.

Who is Usingthe Repeaters
Since Mike Collis was so kind to give us an update on the
Snow Peak repeater located in Southern California I would
like to give all the new ATVers an idea of who is using the
repeaters.(See Mike's report under "ATN-CA Repeater
Reports" in this newsletter)
Snow Peak Repeater
Number of Users (1)
Keith, N6GKBis the only ATVer on Snow Peak and he has
been watching for a couple years. He has a 434 MHz
transmitter and with the problems Snow Peak has he is
still unable to work into the repeater system. Keith also had
a streaming video from the output of the repeater on-line.
Mount Wilson Repeater
Number of Users(1)
Matt, KI6KHB is the only current ATVer on Mt. Wilson and
I haven't seen much of him. Matt got involved with ATV when
he was 15 years old and that was just a couple years ago.
Mt. Wilson is where Mike Collis WA6SVT spends several
eveningseach weekworking at his jobfor a commercial
television company.
Point Loma Repeater
Number of Users (2)
Robert, KA4JSR is the trustee for his club which owns the
Point Loma ATV repeater. The repeaters call is W6RDF and is
not owned by ATN. Robert is the only ATVer I have seen on
Point Loma in quite some time. There was another ATVer
that works at the base and I can't lay my hands on his call
right now. So that makes two ATVers.
Blueridge (Frost Peak) Repeater
Number of Users (2)
Mark, W6MAF is one of the ATVers on Blueridge and he also
runs the Net each week he isn't called away for his job. Mark
has been taking care of the repeater as well as resurrecting the
link to and from Las Vegas via the Mt. Potosi ATV repeater.
Gary, K6IOJ is also an ATVer on Blueridge but I haven't seen
him for some time but I know he is still there.
Mark mentioned that Mt. Potosi was receiving the link signal
from the Southern Calafornia repeater network via Blueridge
during the net this week.
Oat Mountain Repeater
Number of Users (11)
Iuse the Oatrepeater along with a greatbunch of ATVers.
We have Alan, W6IST who is the custodian of Oat and his friend
Joe, K6TBA who both live in the San Fernando Valley. Then there
is Mike, K6LDK in the Santa Clarita Valley are along with Hank
KI6JL out in Canyon Country. I haven't seen Hank is awhile but
I am sure he is still out there.
Here in Simi Valley we have Chuck, WA6FGK who is our "tower
guy" because he climbs towers forhis job. Nice guy to have
around.We also have Bob, W6KGE and he is one of our
designer/builders. A short story about Bob is that I met him at
my first ATV Open House and Bob was interested in some
downconverterplans I had from an old magazine article. I gave
him the plans and happened to give him a call about a week later
and found that he had built a half dozen downconverters and was
already watching ATV. Bob has since produced several additional
generations of downconverters with quieter noise figures and better
selectivity.
Spencer, N6IWY and Ed, K6UUZ are also on Oat and they both are
designer/builders experimenting with all areas of ATV. They have
built their transmitters as well as some unique antenna designs. And
we also have Bill, KF6GJH. And over in North Hollywood we have
Bob, N6BPU working into Oat. Bob has treated us to video from
his remote controls aircraft.
Santiago Peak Repeater
Number of Users (13+)
Santiago is the hub of the repeater network and all repeaters
are linked to it. When Santiago fails all the other repeaters operate
as a local repeater.
AC6RB, George works into Santiago andhe pioneered streaming
the output of the repeater via Camstream several years ago.
George continued with his use of the Internet and today he
has established a Net with his friends in Argentina called
"Spanish/English Net" which is fast becoming an International
Net with ATVers checking infrom Italy, France and Japan.
Gordon West, WB6NOA also works into Santiago. You might
know Gordon for his "Software & Book Education Packages"
for Ham Radio. Gordon always has great newsfor the Net each
week ranging from new productsand upcomingevents.
Gary, W6KVC produces the San Bernardino Microwave Society
meeting and links it to Santiago so we all can attend their
meeting each month. I have to add that Gary sets-up a portable
station each month for the meeting and has the best picture
into Santiago of all the ATVers on the repeater. Maybe we
can get Gary to tell us how he does it.
Al, W6WYN works into Santiago from San Diego and I think
he has the longest haul of all ATVersfor distance.
Merv, KO6E works in from the Santa Monica area.
WB6KJJ, Ed works in from thecity of Orange, Don, KE6BXT
works in from Mission Viejo.
From the San Bernardino/Riverside area there is KA6JJH Ted,
KD6OMV Norm,N6ESW Mike, KA6DPS Dave and WB6HYH
Tom. And N6HOG, Barry works in from the Glendale area.
There are a couple new faces I have seen on the network
but I don't have their calls or names since I haven't made
contact with them, yet. I did say Hello to Ken, KB6EVR
during the net this week. I think Ken has been involved in
ATV for some time and is just getting back on the air.
That is about it with the exception of a couple clubs that
come on from time to time to test their stations.
If I have overlooked anyone it is not intentional and I apologize
in advance.
Mike Collis WA6SVT the owner of all the ATN repeaters
doesn't have an ATVstation so I didn't count him. Sometimes
he does key up the repeater on Mt. Wilson while he is at work.

Snow Peak Repeater Up-Date
Mike Collis WA6SVT sent me a couple emails up-dating
the condition of Snow Peak. I thought I had misplaced
the first email and Mike sent me the second. Since then
I found the first. Here are parts of Mike's emails:
Snow Peak:
The 2441.5 MHz input works including audio, the noise you
are hearing from a staion on the Snow Peak Repeater via
other repeaters like oat or Santiago is the 2417 MHz link
receiver picking up a WiFi link at 2424 MHz, they are
11 MHz wide and the lower edge of their signal is getting
into our audio subcarrier.
We are only protected to 2417 MHz as primary and above
that secondary. The FCC will protect our primary but not
our secondary part of the channel. Perhaps, I could move
down a bit but stay within our 17 MHz wide channel to
stay clear his QRM. The link was last year tried higher in
the band but QRM to either our 2441.5 MHz input or
QRM to Broadcast Auxillary Service (news links from
choppers and trucks to Santiago on ENG channel 8, 9,
and 10 took place so he went to 2424 MHz to cause the
least disruption and has declined to go to 5.2 GHz band
for the link.
73s,
Mike
And this from Mike's first email about the 434 MHz problem:
The 434 receiver works but we have intermod now due to
three LPTV station tied together on the same antenna with
less than required filtering. I am in contact with the offending
stations. I plan a trip as soon as it can be arrainged with the
various parties to resolve it. Perhaps for now I should just
unplug the 434 RX to stop the repeater chatter and
stations can use the 2.4 input.
Thanks,
73s,
Mike
Thank you Mike for keeping us informed.

Repairs Needed for the ATN-CA Repeaters
______
Blueridge:
1.Establish link from Mt. Potosi
Mt. Wilson:
Oat Mtn.:
1. Replace plastic wire ties with appropriate fasteners.
2. Tune 2.4 GHz link dipole for better SWR. It would be a
good idea to sweep the 1200 MHz antenna at the same
time as well.
Santiago Peak:
1. Remove KC6UQH's call and Palomar from the W6ATN
repeatersID's (late spring early summer08when the new controller is installed)
2. Look into weak signal getting into one of the inputs.
3. Find intermittent receive problem for link from Oat Mtn..(1/24/09)
