Soldering Surface Mount Components
The "Tech Talk" of the San Bernardino Microwave Society
Meeting this Thursday was a demo using "solder paste".
Jeff and Larry did the demo using a "hot plate" and also a
"toaster oven". Using a product made by "Zephyrtronics" we
were shown how they applied a small amount of the solder paste
to a surface mount component on the board and basically pasted
it on the PC board. Then they pre-heated the board (with the
component on it) on a hot plate surface to about 300 deg. They
then used a heat gun on low to add a little more heat and the
gray color paste turned silver and it was done. Very slick. And the
blowing of the heat gun didn't move the component because
it was pasted on the board.
They also did the same thing by pasting another component
on another board and then the placed it in a pre-heated "Toaster
Oven" andwaited forthe board to warm and the paste changed
from it's gray color to silver. Very interesting way to deal with the
problem of working with very small components.
If you would like to know more about the Solder Paste by
Zephyrtronics their website is www.zeph.com and I am told that there
is a video of how the process is done commercially. Zephyrtronics
tag line is, "The world's first comprehensive low-temp approach to
the electronics bench top.
More info on the SBMS Meeting:
The streaming video from the W6ATN ATV Repeater didn't work until
KE6BXT logged on about an hour and 15 min into the meeting. Don
stopped and then restarted the stream and it began working.
The SBMS noted that this had happened during their meeting for the
last several months.
500 LBS of Diodes for the SBMS
One of the members of the SBMS mentioned that he had won a bid
on eBay for 500 lbs of diodes. The club should be set with diodes
for several months. Hi Hi
I want to thank the San Bernardino Microwave Society for their monthly
meeting and how professional your club is operated. You all seem to
be a great bunch of gentlemen.
KD6ILO on BATC
Here is an email from Mario:
I now have a streaming active account withe BATC (British
Amateur Television Club)under member streams, http://batc.tv/.
I think this will help me more in getting the information out
about ATV here in WWA in the Puget Sound region and beyond,
73 Mario,
KD6ILO.
Thanks Mario for keeping us up to date.
Emergency Preparedness Expo 2009
Spencer, N6IWY and Ed K6UUZ will be manning an ATV Station
at the Expo held in Simi Valley this Saturday. MARCH 7th.....
The Expo starts at 10 AM PST and runs to 2 PM and if local ATVers
are around it would be great if you would givethe guysa call to keep
them company and have someone to demo to.
This will also be seen via the BATC.TVon the W6ATNrepeater
stream. The Expo starts one hour into the"Argentina ATV Net" that
AC6RB, George has on every Saturday morning that runs 9 to 11AM
also on the W6ATN repeaters.
I suspect that Spencer and Ed will be logging into Georges net for their
first hour and take over the batc steam when he is done.
The Expo has demonstrations on: Water Storage, 1st Aid, 72 hour Kits,
Food Storage & Cooking, and Emergency Communications..Ham Radio.
They also have 40 min classes on Survival Techniques, Family Emergency

Don't Forget
Argentina ATV Net
The Argentina ATV Net starts this Saturdayat 9:00 AM PT
(1700 UTC) and runs to 11:00 AM.
The Net was established by George, AC6RB a well know ATVer
here in Southern California so hecould communicatewith his
friends in Argentina. And he will be using the BATC.TV streaming
video and EchoLink to make the two way link.
I have watched George and his friends testing the system all
week getting everything ready and working out bugs.
George has invited everyone to tune in here on the local ATN
repeaters and anyone else that would like to participate
using BATC and EchoLink.
To tune-in go to www.batc.tv home page and look on the left
column for a button titled "ATV Repeaters", click on that button.
You will now be on a page with a drop down list where you will
want to look for "W6ATN" and click on it. Then click watch and
you will be good to go.
If you would like to join in the Net net while watching on BATC
you canuse EchoLink. You will need to subscribe to EchoLink
via the ATN website so it will operate through the ATN repeaters.
Go to www.atn-tv.org and look for a button in the top banner titled
"EchoLink" and click on it. This will lead you through the process
to set-up your connection.

DATV Question
Hi Bryon
For the ATV Newsletter under the Digital headline.
When using DATV on 70cm, 436.00 MHz we use an up
converter to convert 70cm to L Band to enable the signal
to be received on a satellite receiver.
This means building an up converter or buying one ready
made, quite costly.
There are UHF to L Band up converters available sometimes
on Eaby for $10 to $20 These have been used in the US
Cable TV networks for viewing Digital TV sent on the cable
at UHF on a regular satellite receiver.
One example of this is the Glencom VC510. This has a
LO frequency of 1,950 MHz so that 436 MHz is converted
to 1,514 MHz It requires minor modification to remove the
cable coupling components and it is then ideal for feeding
a digital satellite receiver from the up converted 70cm signal.
My question is do any of you know where to get these surplus
cable TV up converter from?
Please let Bryon know for the next issue,
73's
