Dayton = NEW STUFF!!!!
This is a great idea from Ten-Tec which was introduced at Dayton....I give you the QRPer blog he has done a stellar preview. Check it out and get the grey matter excited!!
Alexloop vs Attic dipole
Setup for test. (Laptop running Ubuntu update) |
A-5
K3
SFI 157
SN 173
Below is the results of the test.....not so well it would seem the Alexloop netted zero and the dipole only one. So is seems for a more acurate comparison better conditions are needed.
The Alexloop vs my attic dipole
The new Alexloop antenna |
A quality case |
So lets get to the nuts and bolts.....how does it work....sure anyone can say anything about their antenna but the proof is in the radio waves!!
Antenna location..cat standing guard |
I wanted to do a comparison between my attic dipole which is the Alpha Delta DX-EE up about 30 feet in the attic and the Alexloop set up in my XYL's office just opposite my radio room. Let me state that this is not a comparison to see which antenna preforms better as that is not a fair comparison....but I wanted to see how well the loop did compared to my attic dipole. The Alexloop was mounted on a tripod....well ty-wrapped to it as the the Alexloop would not fit over the tripod center pole section. This is something I will have to work out later. Each of these antennas have their disadvantages....the dipole is in the attic, this means a wooden roof above, rafters all over and insulation below. The Alexloop is in a second floor room, it's a small loop antenna and very close to the ceiling. So really both antenna are far from ideal when it comes to location.
Temp tripod mount |
My overall impressions of the Alexloop are as follows:
1. Shipping was fantastic, this antenna got here from South America faster than products I have ordered from the U.S.
2. The support is great, I had a question about the loop when it arrived and it was answered within 30 minutes!!!!
3. This unit is quality quality quality from the carry case to antenna!!
4. The tuning was a cinch, turn for peak noise and then transmit and tune for lowest SWR....takes about 20 seconds!
14.060, 7.032 Alexloop |
6. Antenna foot print is very low profile and can be used vertical or horizontal.
7. The SWR on 20m and 40m (only bands used so far) was 1.4 at 14.060 and 1.7 at 7.032.
The bottom line is I am very very impressed with this antenna and I will be taking it to the field and updating the blog on how it does. Up to this point would I recommend this antenna.......dam right I would it's support is excellent, quality of the product is way above par and so far the results have been very impressive.
Time to do some kit building
Oliver is keeping an eye on things |
Control board completed Some tricky lead forming |
As was said I am in the process of building another Elecraft K2 and I have another blog that deals with the build. I wanted to blog the progress but also highlight other areas such as toroid winding, what was needed to be a kit builder and so on. There are specific posts about the K2 build it self making mention of tricky sections of the build and how it was handled. It's now time to see if the bands have come alive!!
MFJ 1026 noise canceling unit…for today ham!
Things don't seem to work when you really need them |
K1EL Winkeyer USB complete
K1EL Winkeyer ready for action |
The first day of assembly |
Battery holder |
building will be a smooth experience. Take your time building the unit, it's not a race as certain components such as USB connector, 1/8 jack and 4 way RCA jack should be mounted with care. This makes the final assembly of the two metal covers fit without any surprises.
Kit complete |
1. There is a 10k potentiometer and the shaft was just a bit to long and I had to trim it. This was only for looks as I did not like the knob extended away from the keyer.
2. No hookup wire was provided to go from the potentiometer to the board. This is no big deal either as I did have the wire...but.....it would had been nice to include it in the kit.

K1EL WKUSB keyer
About a month ago a new kit arrived and is still sitting waiting to be built. With some thought and over time I ended up selling my Logikit CMOS4 keyer that I built. I sold it not because it's a poor keyer but being a stand alone keyer made it for me a hassle to program. I missed just starting up the PC opening a program typing in what I wanted the keyer do and simply saving that sequence. I do a lot of CW contests and have to keep changing the exchanges. With the CMOS4 keyer I was always taking out the manual and refreshing my poor memory with the proper sequence of buttons to push on the keyer to enter and save morse code in the CMOS 4 memory.
So I sold the Logikit keyer CMOS4 and Julie had purchased me the K1EL WKUSB keyer kit. I am familiar with the WKUSB keyer as some years ago I did purchase a built unit and it worked great. At the time it did seem to have some issues with my contest program N1MM. I ended up selling the unit and as they say hind sight is 20/20 and if I knew then what I do now I would still have it. This keyer has been around for some time now and improvements have been made. To hook it up to the PC is a simple USB cable along with some software and you are off to the races. To change the CW messages you open a program on your PC enter your new message then save to the key and that's it. You are able to enter four separate messages (just great for contests or DXepedtion contacts) The keyer can be connected to two rigs, my K3 and K2 can use the same unit without cable swapping. So back to the software for just one more moment.....not only can you program messages BUT there is a slew of custom settings you can enter such as spacing, weight and tone just to mention a very few extras. I hope this weekend to heat up the soldering iron and point it in the direction of this kit!!
