Summer Gathering happens at Valley Camp ( N47.4680 W-121.6808 ):
http://valleycamp.org/ located near North Bend, Washington 10 minutes
off of I-90 at exit 34. At the bottom of the Exit 34 ramp, turn left
(north) and continue 1/2 mile past the convenience stores and truck
stops and watch for the right turn onto SE Middle Fork Road (County
Road sign says Valley Camp 2.2 miles). Continue to the "Y" and take the
left on SE Middle Fork Road (lower road). Follow until you come to the
stop sign. The entrance to the camp is straight ahead across the small
intersection. The camp call is WA7VC. Check out WA7VC on aprs.fi
Valley Camp is an incredibly beautiful place. Nature trails and
birding opportunities for the family abound along the Middle Fork of
the Snoqualmie River. I promise you will see Elk and deer. Bring your
thirst for knowledge, some warm clothing for the evenings, a chair and
something soft to enhance your enjoyment of the picnic-table seats.
Saturday, breakfast, lunch and dinner are being provided by Steve and
Tina Stroh to maximize your opportunities for social and technical
interaction. To "rightsize" the food purchased, number of meals
provided, please register your interest in attending SG by filling out
the form at https://goo.gl/YLfEUm. Coffee is provided each day...
Breakfast is 0700 to 0830 – Not to be missed.
The event runs on donations and we encourage you to donate $25 for the
day plus the cost of the overnight housing. There is a donation box
for the event. If you donated what you would pay for the tasty meals,
we would probably be in great shape. Please help us keep this event
going for another 19 years! This venue is made available to us at no
charge but it cannot continue to happen without your participation and
We are still working on it, but here is an idea of what the content
should be this year – if you don’t see your favorite topic –
propose a presentation on it – we are trying for a larger number of
focused mini-talks with just enough time allotted for treatment of each
topic and questions:
There will be excellent operating conditions for you to try HF - rigs,
computers with lots of digital modes, interfaces and 3-element Triband
antenna or some awesome wires in very tall trees…Lots of space to
experiment with your next antenna project and excellent analysis
tools…Bring your projects for help from knowledgeable folk and access
to great test equipment. Never done JT65 or WSPR? Want to send some
Email with the Winlink2000 system, need help configuring a soft modem
or setting up a SignaLink? – we would be honored to help get you
Proposed Topics:

Getting Started with APRS - why use digital modes, what characteristics
make them so effective. Software Replacements for Hardware TNCs Direwolf
and UZ7HO Soundmodem. Curt Black – WR5J
Near Space Balloon Launch and Balloon APRS Adventures – Yep – We
said LAUNCH. Still looking for payload components – contact us if
you have a tracker to commit to the project. Due to the Wetside launch
location, we have little confidence on getting the payload back. Paul
Verhage, AF7HL
9600 Baud Packet Demo - a pair of systems that can do 9600 baud and do
many "Internet" things - display web pages, send email, etc. There will
be Raspberry Pis on both ends Steve Stroh, N8GNJ

State of the Science in HSMM/Mesh Networks for Hams – Regaining Lost
Local Momentum

Update on HamWAN – another year of amazing progress

Round-Table Session – Compare and Contrast APRS Clients:

Update on use of FLDIGI-FLAMP – and RMSExpress transporting data from
the backcountry for 800 cyclists in RAMROD – (Ride Around Mount
Rainier in One Day) to the start/finish line. Update on the BIGFOOT200
foot race – great future opportunity for digital data transport.
RTL Dongle: Planes and boats and hams (Oh my!) Ken - N7IPB
Inexpensive USB interfaces originally designed for DVB-T TV tuners have

become the poor mans Software Defined Radio. Usable over wide
ranges they can receive nearly every modulation given the appropriate
software. This talk demonstrates the use of $20 RTL-SDR dongles to
receive ADS-B (Automatic Dependant Surveillance – Broadcast) aircraft
and AIS (Automatic Identification System) for vessels, displaying them
on Xastir.

9.6Kpalousa -- It's time to move from 1200 bauds (it's been 38 years)
John Hays and Brian Hoyer
NW Digital Radio will setup a test bench at the Summer Gathering to
help get stations operating at 9600 baud packet. This is your
opportunity to get your equipment up and running on 9.6K packet.

We will have spectrum analyzers and deviation measurement equipment
setup to make sure your configuration is optimal.
Bring your 9.6K capable hardware or software TNC, your radio,
connection cables, and documentation on adjusting the radio's deviation
and TNC levels.
If you don't have a 9.6K capability. We will be offering the UDRC for
sale on site (or pre-order). You need to provide:
1. A Raspberry Pi 2 or 3
2. A 9600 baud packet capable radio with appropriate cable
o Mini Din 6 on the UDRC to your radio's interface
o We will bring a soldering station if you need to put a connector on a
Mini Din 6 cable,
3. A micro SD Card, preloaded with Compass Linux and direwolf
o We can load your SD Card on site.
4. Power supply for radio and Raspberry Pi (3A recommended)
There will also be examples of messaging applications as well as APRS
applications available for running on the Raspberry Pi.
There will be free beer with every new digital mode you try...there are
more than 120 modes inside FLDIGI alone… Good Luck exploring those
– or watching others try!
There will be cheesy Sci-Fi Movies and popcorn late into Saturday Night
thanks to Bill, WA7NWP ...
