SWR 1.1:1, power 5 watts and memory CQ message

With getting most if not all of my "to do list" done it was time once again to swing the Alexloop into action and have a nice late afternoon of ham radio and relaxation. Setting up the loop has become faster for me I'm getting the hang of the in's and outs of the loop. I also am able to tune the loop in less than 20 seconds and be up and running on different band segments. The SWR is anywhere from flat to 1.7:1 and the band width is very good and retuning is not needed unless 20 khz changes are needed. This weekend the Worked all Germany CW contest was going on so I wanted to be a point giver for the contest. With 5 watts, my KX3 and the Alexloop in the living room I was able to contact the following  all on 20m:

DK1NO
DK9PY
DR4A
LX/DF1LON

  I did try dropping the power lower than 5 watts but is was just not doing the trick. I then was on 30m and WA3SCM Dave was calling CQ. I came back to him using 5

Time to recharge the battery

watts. I was at times in and out with Dave but he was in P.A and that's off the backside of my loop antenna. Dave was running a long wire with 100 watts and all was going well until my KX3's batteries decided to die! The KX3 just shut down and my lesson was learned in that I should be monitoring the voltage on the KX3 (via it's display) and I would had known it was due time to change over to my external battery supply. I did go upstairs and get the extra battery but it was too late as Dave was gone. I did email him and explained what happened and on Sunday he emailed me back. He was wondering where I had gotten to and did tell me that he was very interested in the Alexloop as he has worked with lots of different types of loop antennas.
I was able to spend some time on the radio today (Sunday) and I again tried 10m to see what was happening.....it turned out that 10m was good to me today. I was only able to make 2 contacts but they were sweet ones!

IS0GQX from Sardinia
MD0CCE from Isle of Man

I was shocked at both these contacts two very nice and sometimes rare areas and I did both in one day! If I get the time this evening I will try some more radio time but if I don't get around to it I am very happy with the two contacts I did make today.

It was another great day on 10 meters. I was spotted on 5 continents with 5 watts WSPR. No time for doing other things on the radio such as making real qso's. But this was fun too.

Hanz, W1JSB and I hiked near Profile Falls in Bristol today. We worked Germany, Canary Islands, the Netherlands, Ontario and North Carolina.

Here’s a photo of Hanz setting up his gear on the bridge abutment.

We set up our gear on the old rail right of way on the edge of Profile Brook. The rails are gone and the bridge is unused, but the stone abutment remains. It’s a pretty spot. We operated here in the early spring.

I heaved a line into a tall maple tree near the old bridge site. We pulled up a 33 foot wire and I connected a 9:1 unun and started operating the KX3 on 15 meters. The Worked All Germany contest was in full swing, so we worked quite a few German stations. Here’s my log:

19 Oct-13 1900 21.008 CK3AT CW 599 599 Ontario
19 Oct-13 1901 21.009 DK9OY CW 599 599 Germany
19 Oct-13 1903 21.016 DL0LK CW 599 599 Germany
19 Oct-13 1920 21.020 DK0SU CW 599 599 Germany
19 Oct-13 1924 18.085 KS4S CW 599 599 NC
19 Oct-13 1928 18.092 EA8BBJ CW 559 599 Canary Isl

After operating on 15 meters for a while, Hanz took over. He operated his souped up 20 meter SWL rig in the yellow Pelican box. He worked several Germans.

After a while we switched to 17 meters with my KX3. Hanz worked KS4S in North Carolina and PA3DZM in the Netherlands, and I worked EA8BBJ in the Canary Islands.

The afternoon sky had clouded over and most of the leaves were off the trees. But the air still had a rich fragrance of fall and the lingering warmth of Indian summer. We hadn’t operated together for nearly a month, and it was
great to get out with our QRP gear again.

The old timers reading this are going to be laughing I think!

Ten metres was in good shape today and I’d just finished some programming work on the Anytone rig in the car. I tuned up around 29MHz to see if there was any AM coming through. Sure enough there was.

Barry N1EU was coming through nicely, running an Apache labs SDR which was sounding great. Barry was kind enough to pull my 10W/whip signal out and give me an S5.

Really thrilled to have made my second AM QSO! Hopefully there are more to come.

Things around the house are slowly getting packed away but the ham radio bug still bites. It's true what they say....."you don't know how much you miss something until it's gone.....or semi packed away" Ham radio is not gone from VE3WDM, the antenna may be sold and gone, coax all rolled up and boxed. The Elecraft K3 sits idle at the desk but all is not lost as the KX3 and Alexloop are calling my name!! On Saturday once our Thanksgiving preparations  were going smooth...the turkey was in the oven and the side dishes were slowly cooking it was time to feast on some missed ham radio time. The night before, I charged the batteries in the KX3 having them ready to go if the opportunity came about. It did on Saturday afternoon so I setup the Alexloop in the living room and fired up the KX3. It sure was nice to hear some atmospheric noise and even the woodpecker QRN from some offending appliance was ok as well. (the KX3's NB and NR took care of any offending interference)
I had been reading about some hot openings on 10m's from some of my blog buddies but I found 10m to be dead. I ended up hanging around 20m at the QRP watering hole. My power was reduced from it's normal 5 watts to 3 watts. Julie was on her Mac beside me and since our living room TV had been sold it was a Sony boom box radio entertaining her with tunes. The Sony radio along with it's antenna was only 10 feet from the Alexloop anymore power than 3 watts could be heard over the radio. The way Julie see's it CW is NOT music to the ears and it's much better to be on the radio and have Julie happy thus down went the power.
As for contacts I only made 2 short contacts as I did not have much time and was up and down checking on dinner. I was able to make it into Utah to WA7LNW and N3PDT in Missouri, not much but from the ground floor, indoor antenna and 3 watts I was happy with the contacts. I kept tabs on my signal using the Reverse Beacon Network and it showed only U.S stations were copying my signal. I was on again Monday evening and could hear PV8ADI from Brazil at S8 but I was not able to make contact with him.
The KX3 now is resting on the radio desk and the Alexloop is away in it's carry case until next time. I was please to get this short radio time in and the results were pretty good as well.

This evening I managed to successfully send some APRS messages to the International Space Station that were successfully digirepeated. It might not be a major technical achievement but after monitoring and decoding many passes in the past to now actually send something myself 300 miles up to something traveling at 5 miles/second left me feeling a little chuffed!

I screen capped the evidence from the website http://ariss.net which documents Amateur Radio data digipeated by the ISS. In order to appear on the page, a position report in a valid APRS format must be received and then digipeated through the ISS system, then be heard by an internet gateway station, which then forwards it on to the APRS Internet System.

Okay it sounds a bit more impressive when put like that ;-)

The map showing received stations, M6GTG is me!

The detail of my report

List of stations with time stamps, showing me!

List of digirepeated messages

The equipment I used was very similar to that I used for the APRS IGate setup last month.

It consists of a small embedded PC running embedded XP, the sound card output was connected to the microphone input of my Baofeng UV-5R+ operating in VOX mode set to 145.825MHz. The radio was connected through my power/SWR meter in to the X-50 antenna. I used the UV-5R+ instead of the UV-3R since it has a little more power and better audio. I had a SWR of around 1:1.2 and outputting 4W.

The software I used was UISS from ON6MNU and the AGWPE packet engine. It has taken a little time to work out how to setup UISS into auto-beacon mode and putting in the time of the next decent pass (approx 45 degrees elevation) I set it to broadcast position and text data messages every 30 seconds.

The embedded PC running UISS

UV5R+ in VOX mode on 145.825MHz

The power meter showed 4W output, SWR about 1:1.2

I stood out in the dark, hoping to see the ISS pass over but the cloud cover was too thick and monitored using a handheld scanner. I heard my transmissions obviously and the ISS broadcasts as it repeated received messages, but I didn't know if any were mine till I got back to the PC.
