Today was magic! Everything has turned green in the last couple of days. Judy and I rode our bikes in Old Hill Village this afternoon. I brought the KX3 and worked Slovenia, Lithuania, Dominican Republic, St. Kitts, Indiana and South Dakota.

We started out at Shop Road and headed south. We could tell the Pemigewasset River was high. But we were surprised when we found the road was flooded about a mile into the trip.

We turned around and rode back to the camper. Then we headed south by car several miles and came into the flood control area from the other end. It was gorgeous. After riding for ten minutes or so, we came to a beautiful little cove.

Soon the old road leveled out through a large field not far from the river. But we were on high ground and didn’t see any more water on the road.

We stopped in front of an old butternut tree a mile or so farther on. I’ve operated here before.

You can see Judy in the background. She brought her knitting and is working on some booties for a friend’s new baby. I tossed my line over the tallest branch and set up a vertical wire. I ran the KX3 at 5 watts and started out on 17 meters. Right away I worked W1AW/0 in South Dakota. I jumped between 17, 15 and 12 meters to work six stations in about 20 minutes.
Here’s my log:

18 May-14 2030 24.892 HI3LFE CW 599 599 Dominican Rep
18 May-14 2034 21.035 LY10W CW 599 599 Lithuania
18 May-14 2037 18.068 S51TA CW 559 599 Slovenia

18 May-14 2044 18.077 V44KAI CW 599 599 St. Kitts

From this spot I look east across the Pemi to Sanbornton. It’s beautiful.

I packed up the gear for the ride south to the camper. Judy took a quick snapshot of me and the bike.

This electronic keyer is the only one I had in years. The ETM-2b is ready for the ham radio museum and is 38 years old and still doing its job very well. I made a lot of qso’s over the years with this keyer. I can’t say good bye to this keyer. It will be companion until the end.

In the late afternoon I started WSPR on 6 meter. I was spotted by PA3MET 13 times. You can see the doppler effect or air plane reflection because between our QTH's is Amsterdam airport Schiphol with a lot of air traffic.

No radio today because it's my birthday and a lot of family and friends are coming to visit me.

Over the past couple of weeks, I’ve managed to steal away to the machine shop and continue to work on mounting the Schurr Einbau mechanism. I found a piece of polycarbonate in my scrap bin to make the interface between the Einbau and the base. It turned out that the mounting holes are tapped M3-0.5 so I had to make trip to Ace. While I was there, I picked up some brass screws also. Total cost of the project is 52.99 USD. I bored the holes in the base today with the milling machine and tapped them when I got home. Couldn’t resist putting it all together even though I haven’t finished polishing the base or the polycarbonate plate…

I have had a couple of comments regarding the 80m coil for the homebrew Buddistick.  I had a few minutes today to set it up and try to get it tuned into 3.897.5 which is the frequency for the Arkansas Razorback Net. I think the 80m band might be difficult for this antenna. I was able to get it tuned to the right frequency with a SWR of about 1.4. But the low SWR “width” is not very wide. It won’t cover the entire 80m band without having to adjust the radial in or out.  So I think this would be a very narrow bandwidth antenna on this low of a frequency.

This is the note I got from Budd when I asked about 80m to begin with:

The homebrew Buddistick works well on 80 Meters. Use PVC couplers to allow yourself to go to one inch OD for the coil. The coil length I used Is 11″.  Use the same wire suggested for the other coils….insulated wire. Same gauge. If you wind 110 turns on that one inch form, that coil will be about 9 inches long.  The single elevated radial will be about 66′ long and the wire should be stored on a kite line winder.  This coil, with a Long Whip (9′) on top, should resonate on the bottom end of 80 Meters.  Try that info and tell us where it resonates. Your final adjustments will be on the radial. If you want to go up to say 3900 MHZ, take some turns off the coil after you make your initial measurements.
Budd

So the narrowness of the SWR curve was expected. I did turn on my radio to see what I could hear,  but tuning through the 80m band, I couldn’t hear anything.  Not being familiar with 80m, I don’t know what kind of activity to expected at 4:3o in the afternoon.  I won’t give up. I’ll work on it again but it’ll be a few days.

I am still happy with the homemade Buddistick antenna and my homemade Buddipole. I have also made the homemade Buddipole. I will write a post about that in the near future.
