Salmoncon 2012

Salmoncon 2012 has come and gone. The weather was overcast and a little light rain, but no one seemed to notice.

There were three days of great presentations, demonstrations and wonderful Ham Radio conversations.
One of many Technical Conversations
On Friday the SOTA group activated Little Mt Si.

The main events were on Saturday and Sunday, but many of the die-hard's were on site Thursday through Monday. I think the sign-in-sheet only listed about 60 attendees, but I think there were more.

The long distant traveler was John - N0AR and his family from Minnesota.

The following are only excerpts from Salmoncon, there are just too much to report and I may have some events out of order as reported here.

Jeff and I were up early on Saturday to set out the Fox for the Fox Hunt (see below).
Early Saturday,

We had planned to set them out late Firday night, but too many late activities prevented the effort.

Saturday Morning was started with Curt - WR5J cooking a wonderful breakfast (with a little help from John's Boys). I remembered Curt's breakfast from last year, so I made sure I was up on time.

The Crew is Ready to Eat
After Breakfast and Introductions, the first event was the Fox Hunt - thanks to Jeff - KO7M. The instruction for the Fox Hunt were deliberately vague as scoring was based on the Factoids Collected during the hunt. The hunters ware also instructed to "Expect the Un-expected" for the hunt.

The only detail that was provided; was the approximate frequency used by the Fox - about 10.1395MHz. It as also shown that the Fox can be heard on simple one wire loop antenna and portable radio (the KX3 and FT-817 receivers were a very good choices).

Trying to get the First Fix on the FOX?
After about a half hour, many hunters realized there were more than one Fox, in fact there were three, each sending it's own CW ID in coordinated time sequence with the other Foxes. Jeff and I created the Foxes using the Propeller Microprocessor, therefore anything and everything devious was done in software. Other details of the hunt will be left out of this blog, to encourage others to attend next year.
Wayne and Sandy Getting Their First FIX
A Fox Hunting with one Radio is like Canoeing.
Later that day, awards were given to the Hunters with the most facts about the Hunt.

After the Fox Hunt, Jeff - K07M, gave a presentation on the Propeller Microprocessor showing its architecture and how it could be used in Amateur Radio - the Fox Hunt was a good example.

Lyle - KK7P and Rich - AC7MA presented an update on the KX3, Note with at least three, the KX3 was well represented in the Fox Hunt.

Bob - AD7PB, gave a presentation on his Homebrew Mag Loops and had several examples for demonstrations. He demonstrated how tuning was as simple twist of the knob near the center hand-hold of the loop. He went through the design process for the loop, picking the dimensions for a particular group of bands. I enjoyed the insight, and now plan to create a Mag Loop for my use.

Charlie - N7KN and Roger - K7RXV, gave a presentation on building Tennis Ball Launcher and a demonstration/shootoff followed.

Jeremy - NH6Z gave a interesting presentation and update on the Open SDR project.

There were other presentations, many more short demonstrations and technical discussions that continued through out the weekend.

With John - N0AR's three boys attending Salmoncon, Tess was in "Boy Heaven". She had lots of Ball and Play Time.

Now, . . . only 364 more days until next Salmoncon!

Salmoncon 2012 - Fox Hunt

This is the Salmoncon 2012 Fox Hunt Invitation/E-mail sent to the Puget Sound QRP (pQRP) Group.

UPDATE: I added some selected follow-up.


Hello All,

This is a survey of people who are planning to attend Salmoncon 2012, and interested in a HF Fox Hunt.

If interested, please respond with the type of portable HF Receiver(s) that you will use for the Hunt?

Our Current Plans:

The current plan is to hold the Main Fox Hunt Events on Saturday July 14th.

We may also hold several warm-up events.

For the Hunt, you may find; a loop antenna, camera, headphones, portable GPS, and/or compass, very useful for some of the events.

Rules, Frequency and other details will be provided the day of the events.

Prizes will be awarded !

Several event reminders will follow on this list.


BTW: Hardware or Item Donations for the Event Prizes are encouraged.

Eldon,

I would really enjoy a fox hunt, but have neither an antenna or (I don't think) an appropriate receiver.

Sounds like we might solve the antenna problem as a group. A great project!

Maybe you could give us an idea as to what band(s) your looking at to do this on???? I'm thinking right now that my IC-706 would work but be rather heavy and awkward. Maybe a homebrew rx is in the cards.................

Alan, and ALL

For the HF Fox Hunt, we will be in Near Field area of the FOX, and therefore shielding is almost more important than a good Antenna. Although with a well shielded Rig and a Loop Antenna, and using triangulation obtained from the Null (through the center of the Loop) should help provide good directional information, and using field strength as a indicator of proximity. Another suggestion would be use something like a KX3 or FT-817 with a dummy Load at the antenna, using your body for shielding to get direction and proximity.

Personally, I would use a cheap (or small) radio within an Aluminum Foil wrap, with a very short exposed antenna, which could be shielded with my body. Others may have better suggestions.

Some of the most successful Near Field Hunters, use the least sophisticated gear, others that are real "DF Hounds", use very extensive gear on Long Distant Driving Hunts. This is a short, near field hunt.

We will have several FOX Hunt events, so different techniques can be tried.

This is a "HF" FOX Hunt, but I would plan for maybe something around 20, 30, 40 meters. Most P&C and Salmoncon attendees have seen how small and low power my transmitters can be, and therefore should maybe expect some very weak signals.

To be fair, I can not provide any more details until the event.

Happy Hunting !

BTW, with all of my talk and preparations, Tess has become very interested in this event. She can not wait to see the FOX, maybe it will be as exciting as her Ball. Unfortunately, I think she will be disappointed :-)

Eldon Brown
