Software Defined Ham Radio: Contesting Revisited ARRL DX CW
http://w9oy-sdr.blogspot.com/2015/02/contesting-revisited-arrl-dx-cw.html
Software Defined Ham Radio. Saturday, February 21, 2015. Contesting Revisited ARRL DX CW. The ARRL CW International DX contest is on the air! I'm not a big contester but Flex is slowly honing its contest chops. I mostly play around in this kind of contest to look for new DXCC contacts. Recently on EHAM there was a discussion regarding light weight rigs to take on DX pedition. I made a little argument for the Flex 6300. It weighs 10 lbs and is 11.75" x 13" x 3.875". What the hell does that mean? It means ...

Software Defined Ham Radio: 4K8M UN3F
http://w9oy-sdr.blogspot.com/2011/03/4k8m-un3f.html
Software Defined Ham Radio. Sunday, March 27, 2011. I was doing a little correspondence when UN3F in Kazakhstan. Just as I tuned him in he was working a WB8 and I was getting set to work him and he seemed to disappear, probably going QRT. He was past his sunrise so he was probably heading out to work. At the same time I saw 4K8M in Azerbaijan spotted so I loaded up the memories and had at it, clicking back and forth. Unfortunately UF3F was truly gone but I had 4k8M in the log first call. Hear Ye Hear Ye.

Software Defined Ham Radio. Tuesday, March 29, 2011. Origins and Refinement of the Contest Knob - II. Stu continues with part 2 of his recap of the development of this fine contraption. Just for the record I am never satisfied but I am willing to be bounded :). Sunday, March 27, 2011. I was doing a little correspondence when UN3F in Kazakhstan. Unfortunately UF3F was truly gone but I had 4k8M in the log first call. This antenna was not a very good match for UN3F but a better match for 4K8M. Unfortunately...

Software Defined Ham Radio: October 2010
http://w9oy-sdr.blogspot.com/2010_10_01_archive.html
Software Defined Ham Radio. Friday, October 15, 2010. How my station works. My station consists of a F5K, a F3K, a ALS-1300 solid state amp and several verticals that are fed from an Ameritron RCS-4 antenna switch. Which I have modified for automatic antenna selection, a horizontal flat top openwire fed on 80-6M, and two other verticals that are on independent coaxs, one that auto switches between 80 and 40. And one that is a base tuned 45ft wire vertical. The F5K has many antenna ports. With these progr...

Software Defined Ham Radio: January 2010
http://w9oy-sdr.blogspot.com/2010_01_01_archive.html
Software Defined Ham Radio. Saturday, January 30, 2010. CW WW 160M CW SO2R. I spent some time with the new SO2R setup on 160m this weekend. You may ask how can you runs SO2R on the same band? The answer is two receivers. With DDUTIL set up like this:. Note the 160M entries. Presently the N1MM band map data is being fed from data decoded by Skimmer over the local host telnet connection 127.0.0.1:7300. Once you grab the contact you simply click the call sign:. Only one transmitted signal is. Band skimmers ...

Software Defined Ham Radio: The Amazing World of Ham Radio
http://w9oy-sdr.blogspot.com/2011/04/amazing-world-of-ham-radio.html
Software Defined Ham Radio. Sunday, April 10, 2011. The Amazing World of Ham Radio. So no sooner did I write about the "Knob Project" than did I start to receive email from others who have been involved in developing similar ideas. James KS4JU editor of HamRadioScience. Wrote about development of computer cases with built in screens. His comment is that some of these cases also contain remote controllers. I can see the brain flashes going off all over radio land! And the support of K5FR and DDUTIL. And n...

Software Defined Ham Radio: December 2010
http://w9oy-sdr.blogspot.com/2010_12_01_archive.html
Software Defined Ham Radio. Friday, December 17, 2010. Winter My Favorite Time. This is the time of year I like best for hamming. It reminds me of days gone by when its cold outside. The sky is very dark and the heavens are full of stars bright. I would come flip on the radio and hear what I could hear slowly tuning from bottom and up. The bands are quiet but unfortunately not too many stations are out there it seems. Subscribe to: Posts (Atom). Hear Ye Hear Ye. Software Defined Ham Radio.

Software Defined Ham Radio: FJ/OH2YL
http://w9oy-sdr.blogspot.com/2011/04/fjoh2yl.html
Software Defined Ham Radio. Monday, April 25, 2011. I've been off the radio for a few weeks and flipped on 80M and there was FJ/OH2YL Anne is on DX pedition. On St Barts operating 160-10 CW. She was an easy chip shot from FL. When I first heard her she was working the gray line across EU and Russia. According to the web site she is running a pair of phased HF-2V butternut verticals. She was probably beaming EU as her strength was such that I probably worked her off the side of her array. Hear Ye Hear Ye.
