POTA activation

Tom Sevart
 

Hi all,

If anyone's interested in Parks on the Air, I will be activating Crawford State Park (Farlington lake) K-2333 while I and my family camp there Sunday through Friday. I'll be operating QRP on 40, 30, 20, 17, and 15 meters at various times throughout the week, depending on family activity and weather. I'll also take along a 2m/440 handheld but will mostly focus on HF.

Re: 4SQRP Kits recently built

About the Transformer Experimentation Board:  I got a quick reply from the designer, Bryan K0EMT who requested a photo. I sent it and he saw the problem right away: wrong number of turns plus my cross over didn't run under the toroid and start turns the other way. I rewound the toroid correctly this time and used #22 wire making it easier to wind and solder into the board. The results were amazing! After adjusting my antenna length a bit, it's 53 ohms and no reactance at 7.030 and 14.030 measured with my MFJ antenna analyzer. Fairly broad too and covers nearly the whole band.  It will work on 15 and 10 but not as well. I could do more antenna wire length adjustments but I'm not too concerned with the other bands.  My goal was to learn how to make my own EFHW and use it on 40m with the Bayou Jumper. Mission accomplished thanks to help from K0EMT. 
I experimented with counterpoise lengths from 2 ft (recommended in experimentation board doc), 7 ft (recommended by Bryan) and 30 ft (used with a tuneable EFHW I used in the past).  Neither of them made any difference. As pointed out by Jerry above, my 6 ft of coax from rig to the board probably served as counterpoise.  And Don, thanks for your offer of help. 
My next project will be an 80M EFHW that handles 500W. Of course, I'll have to use big toroids and wire but I can get away with 2 turns of twisted and a total of 14 turns.   I live on a heavily wooded property and there are a few really tall Doug Firs to support that longer antenna wire.

Re: Crystals, crystals, everywhere crystals!

Donald Sanders
 

 For crystal storage I have a piece of white packing foam at the bottom or a small box. The crystals plug into the foam and sit upright. On the top of each crystal I placed a small white label with the frequency  and the rig used in, if special. This makes it easy to choose the crystal and protects them from my occasional fumbling. The labels were printed on address labels in small print. My handwriting is not so clear. A quick spray of clear krylon keeps them clean.

Re: 4SQRP Kits recently built

J.K. Wright
 

I have several efhw - 66ft, 126ft...all have a 49:1 with 15ft counterpoise wires. Also your coax shield will act as a counterpoise. I use a common mode balun (can be an ugly balun) at the 49:1 box. A 66ft efhw should have nil swr on 40m and 20m and be tunable on 10-40m.  You can also ck out a homebrew 49:1 balun by placing a 2.5k resistor across the out put and measure swr at input with antenna analyzer. You should see R of about 50 ohms.

Being a late comer to 4SQRP (started with the Bayou Jumper) I have found the various kits really well designed and a bargin when compared to other gear on the market. My past QRP was my pair of FT-817s I carried all over the world before I retired from Hewlett-Packard. They were sold a few years ago with a goodbye to QRP. The BJ was too tempting so I'm back. BTW, I added the Souperuper and EZKeyer IIi/SMT to the BJ.  I even bought an IC-705 to replace my FT817s. 
I recently built 3 kits that I want to mention:  4S Tuner, QRPoMeter and the Transformer Experimentation Board

4S Tuner: I finished this tuner last night and tested it this afternoon. It went together quite well although it took a search for more photos of the coil winding and understanding the options. Basically, everything needed to build and use the tuner was in the manual. Using PCB material for the case is a fantastic idea.  I like the design of the 4S Tuner because of the IN/OUT switch where you can set the tuner without melting your final transistor. The bridge design with a dummy load makes a lot of sense and I see it used with the QRPoMeter.  For the test, I used an existing 66 ft long wire for EFHW pulled out to 73 ft. I also used the existing 30 ft counterpoise lying on the ground. No problems - it tuned right up on 20M with the inductor set at E or F (goes from A to L in steps). On 40, it tuned right up on L for the inductor (max inductance). I called a station in Bend, OR (I'm near Seattle) and got a 44 report. Then I switched from IN to OUT (duh!) and he copied me Q5! OUT connects the rig to the antenna rather than to a dummy load and bridge SWR detector. This tuner is a worth while project and will go with my Bayou Jumper to simulate the actual Paraset use of a longwire antenna. 

QRPoMeter: I didn't get this through 4SQRP but directly from NM0S. I learned about it from this group, however. This kit went together quite well with excellent build instructions. Like the 4S Tuner, I really like the design and the use of a bridge circuit to measure SWR and a nice load on the rig during the process. Also it provides a dummy load. Back in my FT-817 days, I had an Oak Hills QRP Wattmeter which got sold with the rigs. The QRPoMeter is a good fit and is quite accurate. Its powered by an internal 9v battery and has a very sharp LCD display. Its clearly a superior instrument. 

Transformer Experimentation Board:  This kit has a very handy set of components with the PC board. After learning why certain size of toroids require a certain number of turns, I decided to build the EFHW 49:1 transformer and use this with my Bayou Jumper rather than a long wire as used back in WWII.  I did the winding carefully and gave it a try with a 66 ft longwire and a 30 ft counterpoise. Didn't work. Then I checked the photo and see the jumper is needed to connect the CP to the circuit. Still no joy. My antenna analyzers indicate that its not an antenna for ANY ham band. I checked everything closely and made sure I burned off the thermaleze and tinned the wires, etc. The included caps are unmarked but I measured them and chose the largest one. With or without cap, its the same. I'm at a loss on this one.

All in all, lots of fun building inexpensive projects that make ham radio fun and interesting. My hat's off to all those who design and produce these kits.

Re: 4SQRP Kits recently built

Don, W9EBK
 

Larry, 
My first guess is the counterpoise wire is too long. Based on your description it sounds like you built an Off-center Fed Dipole for 4.875 MHz. 
Try shortening your counterpoise to 3 feet and check it again. 

If you need more details, please contact me. I'll be happy to help when I'm not at work .

Re: If you are going to FDIM/Xenia ...

Jim Sheldon
 

Johnny, Jim (N5IB) and anyone headed to Xenia that does go to the Airforce museum, I can’t remember which hangar it’s in, but there is a small twin engined blue & white Aero Commander 560 in a back corner that was actually used as Air Force One several times for Eisenhower.  For a while, during my Army career, while I was stationed at Fort Devens, MA, I belonged to the Fort Devens flying club and they actually had it in their stable of aircraft.  We had a picture of Eisenhower getting into it framed by the rear door and that photo is still on the aircraft.  The wife of one of our club members made a set of checkered seat covers for it and as far as I know, they are still on the seats.  I took some multi engine flight training in that plane and have actually flown it.  When aviation gas prices got so high we turned the plane back over to the Air Force and they put it in the museum shortly after that.  The one time I went to FDIM, I saw it there and several other hams from here (Wichita, KS) have told me it’s still on display there.

  I had one once upon a time, got the kit from a “new ham” who discovered it was beyond his abilities. Worked swell when I got it assembled and alligned. Can you send the schematics to me if you have them in a digital format?

QRP. Here tinkering with a nn1g 2 board transceiver. 1993 predecessor to 40-40 and sw series. Similar receiver except fixed gain mc1350 between the ne602 and it uses a real variable capacitor. Original builder had not aligned TX and rx, well nearly 0 Hertz difference. Now it's able to make qsos.

If you are going to Hamvention you should go early if you can to catch FDIM. The vendors night is open to all; you have to register for the talks and banquet. QRPARCI is also offering streaming memberships this year, so you can catch the talks at home if you are not making the trip.
