Field Day 2010 - Day 2 - Moscow, ID

My day started at 0400 PST on Sunday. I promised to work 0400 through station close and site break-down and clean-up with the Palouse Hills Amateur Radio Club.

We were very fortunate to get the use of the county sheriff's emergency services trailer, which had some amateur radio gear already installed in it.

As it turns out, this particular emergency trailer (see photo below) had never been used until this Field day!

In a way it was fortunate as we uncovered several wiring and grounding issues that we addressed.

This worked out to be a great operating station and was able to accommodate several two-man operating positions throughout Field Day.

In addition, the trailer came with a nice crank-up tower which we put to good use to support some of our antennas. Nice.

One thing is for sure, we are now ready for true emergency operations since we now have first-hand experience with this unit. Next time (or I guess I should say the FIRST time) there is an emergency we'll be prepared should our assistance be needed to support emergency operations.

This next photo is a look at the tents that were set up for those
hardy souls who stayed overnight at our site. As it turned out, 80 meters really heated up and, at one point the guys cranked out over 100 QSOs in a hour! FB!

The only downside was sleeping on the ground, ah well, all for a good cause, right?

Next day W7NGI made cooked up some amazing pancakes and bacon to get things off to a solid start. Thanks, Ken! And he did it all on a classic Coleman propane camp cookstove.

Someone also brought in some ripe cherries (no doubt from Washington) which made a nice finish to breakfast.

...still not sure what that huge jar of pickles was all about, however...


Here's a shot of the combination breakfast and break tent set-up that was set up.

That's KI6DER, PHARC President, taking a break between sessions. BTW, if you ever need coax, he's your man.



Next, we've got a look inside the "shack:






That's KK7VO notching another contact in the early morning hours. I believe her dog Daisy (just out of view in this shot) was logging for her.  : - )

In the next shot, we've got Joe and Ken burning up the band on 40 meter phone. Ken's got logging duty while Joe's in the hot seat.

We worked many states from Alaska and Hawaii to Texas, Ohio, Vermont and Massachusetts and more.

We were able to work phone, PSK-31 and, after a fashion and thanks to KE6DWM, we were able to notch a few CW contacts as well, though not how I had anticipated. He was able to get us set up to run CW through his PSK interface to a Yaesu rig. Worked great. Couldn't use my key since the Yaesu has a mini jack and I had a 1/4 inch jack on my key.


The next photo shows one of the other operating positions we had set up

We also had a GOTA position set up, which was great since we had folks from as far away as Alaska (well kind of) stop by to visit.

In addition KE6DWM's XYL took and passed her Technician license during Field Day. Congratulations!!

Do we get extra points for that?  : -)


On top of that, she stuck around and made a bunch of contacts at the GOTA position.

Can her General class be far behind?

In this next photo we've got a shot of one of the "towers" we erected for our antennas. KK7VO had a 80-10m antenna attached with a nice loading coil near the center.

Although this shot only appears to show a single guy wire, there were two others that kept this pole in place.

It did a good job for us supporting, I believe, 3-4 antennas.

We wrapped things up at noon PST having racked up more overall points than our 2009 Field Day performance, not to mention all visitors we had.

All in all it was, for me, a great Field Day experience.

I'm really hoping that for Field Day 2011, I'm ready with a full, self-contained QRP CW operating position, complete with antenna.

I was the only one in PHARC able to copy code at this year's field day, so my QSOs got us a few extra points.

That's all for now.


I'll say 73 and look to see you all at Field Day 2011!

Field Day 2010 - Day 1 - Viola, ID

We had a fabulous weekend for Field Day 2010. Temperatures in North Idaho were in 70-80F with bright blue, clear skies and nary a raindrop in sight.  Woohoo!

Since I belong to 2 clubs in the Moscow-Pullman area I decided to participate with both clubs this Field Day. So on Saturday I joined my fellow hams in the Schweitzer Engineering Laboratories radio club (K7SEL).

We set up shop at N7CE in Viola, ID. Great location with lots of room to spread out, set up an antenna farm, rigs and other assorted Field Day gear. I arrived at about 0830 PST to get things started.

Here are Joseph and Ron getting a station and logging terminal set up set up in N7CE's "shack":

Feed lines run in through the wood insert in the window on the left. Battery power was on the floor, right below the laptop.

We operated phone, CW, and PSK-31 on Saturday and did a credible job, once some minor battery charging issues were resolved.

Got the chance to help set up antennas, rigs, feedlines and more. Really enjoyed it.

Here are a few more photos of set up and operating at N7CE:







Here is one operating position just about ready to go. Just had to run feed lines in from outside.

As for antennas, we had quite a range.

Below you'll see a nifty telescoping fibreglass pole we made into a 40 meter vertical. Light winds made it a cinch to set up and guy and it did a credible job for us, though not quite as good as the ladder line-fed dipole that was rigged up.

Here's the fibreglass vertical, ready to go, complete with pink safety strips to avoid "clotheslining" problems. Note the amazing view out beyond.

We had a small crew throughout the day on Saturday. We typically had a two-man team running on 40 and 20m. One operator and one logger. 

We would alternate between phone and CW when we rotated operators and loggers. 

We had one visitor to the station, see below, so we had an opportunity to show a non-ham what ham radio is all about and how the Field Day worked.

In the next photo, N7CE takes time to explain what all the fun is about to our visitor, Prasad. 

N7CE also had an opportunity to QSO with his brother who I believe was in New Mexico. 

At about 1700 PST I had to head home at attend to things on the homefront.

Just before I left we took some time to get the 6 meter antenna up for the night crew. 

The next photo shows the 6-meter antenna before we got her raised up. 

 Here's the 6 meter antenna after we got it mounted and ready for action.

Had some great chow, thanks to N7CE and his friend.

This was my first real Field Day experience since I began in ham radio back in the 1960s. I had been to a couple of Field Days but had never actually participated like I did here.  What a blast!

Then I headed home to Moscow to get ready for my 0400 PST wake-up call and rendezvous with fellow Palouse Hills Amateur Radio Club members at the Latah County Fair Grounds just east of beautiful Moscow, ID.

Luckily for me, the fair grounds are in walking distance from my QTH.

For details of my Sunday Field Day adventures read the next post. 

73!

N7RCS over and out.

My first ham radio gear

Got to thinking about how I got started in ham radio and remembered the gear my Dad, somehow, obtained for me. Thinking back on it now, the gear he got me was really amazing! I'm pretty sure he got the transmitter, a crystal-controlled Heathkit DX-40 CW rig, at the local Lafayette radio store. The thing could put out 60w or so.

I think I had two JAN crystals, one for 40m and one for 15m! The rig had a hole on the right side where the crystals were inserted. I remember how great it was when I got two more crystals. Now I could actually switch frequencies on one band!

Those were the days... Anyway, I went over to RigPix and they had a photo of the Healthkit DX-40 in all its gray glory! Although I don't recall that my rig had an indicator light like this one does, this rig was built like a tank.

My antenna was a long wire that ran out the window frame and across the back yard to this old, unused phone pole that was probably on our neighbor's property. Any, as I recall it did a pretty credible job for me and was practically invisible to our neighbors because it was so small.

On the receiver side, my Dad, somehow, got hold of a Hallicrafters SX-130 shortwave receiver, a triple conversion superhet with some pretty slick filtering capabilities (at least for a 13 year old kid new to ham radio)! I actually still have it, although the plastic slide switch for selecting AM/SSB has cracked and no longer works. Tuning was a bit of a chore since you had to set one dial to calibrate the tuner for a specific band. The other dial handled fine tuning. Very simple set up.

Plus, this baby has a full complement of tubes and everything. Weighs a ton too. Nice. Here's an excellent picture from RigPix, 

                                   

I wish I knew how my Dad got this radio. Probably one of his IBM ham buddies. 

Thanks Dad for the unforgettable memories and getting me started in this great hobby!

Stealth antenna and feedline

Where's the antenna? That's the point. You can't see it!
The design is a modified version of KR1ST's stealth HF coat
hangar antenna. Running QRP with an ICOM IC-706MKII
I've worked stations in Hawaii, New York, Texas and Chicago
from my humble QTH in Moscow, ID in the shadow of mighty
mile-high Moscow Mountain.

Even standing in front of the house on the sidewalk it's
virtually invisible. The 100 foot dipole is there, however, running
just beneath the second floor gutter.

As for the feedline, if you look very carefully you can see
the spacers on the open wire feedline. They appear as short
horizontal lines against the side of the dark green trim to the
left of the long window on the house.

The 100-foot dipole antenna and feedline

are actually two continuous lengths of #14

wire. The antenna is wrapped around most

of the house about 20 feet up.

The feedine itself is about 20 feet long, beginning

just below the gutter near the roof and continuing

down the side of the house to the garage.

This view shows the feedline (note horizontal 

open wire spacers) as it runs downs the front 

of the house and jogs in to where the it enters 

the garage where my shack is located.

Look very carefully again to see how the

feedline turns to run into the external wall

of the garage.

Here is a view of the open wire feedline

coming into the garage and my shack.

Note how it attaches to a balun fed by 

RG-8X coax to the transceiver.

This view shows my TenTec 1340 QRP 

kit rig (black box in lower left of the photo).

Homebrew station ground ready for action.

Devised a ground system for my shack based on a design from the 2009

ARRL Handbook. Total cost: under $20.

A 2-foot, half-inch copper pipe and stainless steel hose clamps allow
connections to multiple pieces of station gear.

External view shows where tinned ground braid exits

the garage wall and connects to a 6-foot ground rod.

Inside view shows ground braid running inside the station several 

inches from the garage floor and up to the 2-foot, half-inch copper pipe.

Braid is connected to the pipe using a stainless steel hose clamp.

View also shows ground braids running down from gear above and
attaching to copper pipe.

Detail showing connecting of external ground
braid connecting to copper pipe and connection
for equipment ground.

Applying fixes to my Ten-Tec 1340

I added a 1N4001 diode to the power supply circuit to prevent (future) problems in case a power supply is hooked up with reverse polarity. I wish I would have taken the advice of K7QO when I was building the kit! Doing so would have prevented all the problems I'm trying to resolve right now. Live and learn. 


I also replaced a blown Op-Amp (thanks, Mouser). Still may need to fix a few other components as the keying stage is still not functioning properly. May have to replace the other two transistors there, I have them, but am touching base with Ten-Tec to confirm whether I should. 


Can't wait to return to the air!

A long-overdue update

Completed construction of the Ten-Tec 40m XCVR. Ran into a few minor issues so the rig is still not on the air. Need to replace an op-amp, do some final testing and tuning then it's time for some serious QRP fun! Major shout out to Garry at Ten-Tec who was invaluable helping me troubleshoot several technical issues.

Also - finally got an outdoor (stealth) antenna in place. Built a variation of KR1ST's stealthy HF coat hangar antenna. My version does not include the coat hangar, but it is identical to KR1ST's otherwise. Works great and can barely been seen, even from the sidewalk in front of the house.

Far superior to anything I had indoors, even up in the attic. Excellent east-west propagation.  It literally wraps tightly around the second storey of my home. Ideally I should add stand-off's to keep the antenna off the house, which is covered with "concrete" siding. Feedline comes into the garage then into a balun with a coax feed to the rig.

Still plan to build either the KX1 or NorCal 40 for my next project.
