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. Ken W6HHC

Oat Mtn. News


^ 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 least two times

that Mike Collis, WA6SVT told us that he rotated the

community 70 cm antenna on Oat to favor an area to 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 got permission to turn the antenna back

to it's original position. A check with the site owner could 

shed some light on the problem. 


^ This weeks Joke:


Got a joke? send it to

^ Southern California News



Who is Using the 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, N6GKB is 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

evenings each week working at his job for 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)

I use the Oat repeater along with a great bunch 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 for his 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

downconverter plans 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



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 and he 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 in from 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 news for the Net each

week ranging from new products and upcoming events.


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 ATVers for distance.  


Merv, KO6E works in from the Santa Monica area.


WB6KJJ, Ed works in from the city 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 ATV station so I didn't count him. Sometimes

he does key up the repeater on Mt. Wilson while he is at work.



^ ATN-CA Repeater Report



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.





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.






Thank you Mike for keeping us informed.



Repairs Needed for the ATN-CA Repeaters

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

    repeaters ID's (late spring early summer 08 when 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)

4. Resolve problems with WiFi getting into receiver for Snow Peak

    & Point Loma (April 28, 2009)

5. Install new 5 GHz transmitter once it is repaired (3/10/09)

Snow Peak:

1. 2.4 Ghz input is operational but has audio problems due to

    receiver problems on the network hub.. July 23, 2009

2. 434 MHz input still doesn't work. July 23. 2009 and may be

    turned off.

3. The 1200 MHz output does work and you can watch.

Point Loma, W6RDF: No Repairs Needed/Fully Operational

   Trustee Robert Swain, KA4JSR

1. Off the air do to AC problems at the shack.

Mount Potosi:
