MixW Telnet DX Cluster Setup
MixW is an old, and unsupported program, save for the Yahoo MixW group. MixW is also the best program I have ever used for RTTY contesting, bar none, and around 4000 other users agree if the membership of the Yahoo MixW support group is any indicator. I moderate that group, and of late (2014), DX Summit changed it’s format and has broken some functionality of MixW for using DX clusters. I thought it might be good to put together a guide for how to set up MixW to use Telnet, as opposed to web based DX cluster population of the cluster selection window thus freeing the MixW user from external web page changes breaking the MixW software in the future.

Review of the 30 Meter MonoGAP
The first thing I did was to start WSPR off using the new antenna… All the usual suspects came in all a bit better than before! Next I decided to see what one watt could do using JT65 and PSK Reporter… The photo at the left shows what happened, I am transmitting from Oregon… Continue reading
I have RFI, now what– Part II, House Cleaning
I then brought up each circuit one at a time… Remember I had all the major appliances unplugged, so this test is looking for the various vampire devices that suck electricity all the time, pretty much anything with a wall wart on it. First I brought up the kitchen. That caused no issues, so I started turning on lights, and plugging things back in. The first source of RFI I found was a set of LED lights I got from Walmart. They are the ones that look like a 100W light, and put out about as much light as a 100 watt light. I heard nothing from them on 80, 40, 30, or 20. However on all bands above 20, they put out a horrific spray of RFI. Had I not checked all bands between testing I would have missed this. OK I noted this in my log book, and put a note there to change them out later. I turned them back off, and plugged in the refrigerator, I got a bit of RFI, so I added a few 31 mix ferrites to the power cord, and that RFI did not return. Next the Microwave got plugged back in, again, a small amount of RFI, and again a ferrite or two took care of this. There were no wall warts in the kitchen, so that pretty well took care of things for the kitchen. Continue reading
I have RFI, now what– Part III, Quantification
Over the past few years my RFI problem has been getting worse and worse. 40 Meters was unusable due to QRM last year, I am only now beginning to be able to use 40 meters again. Other hams in the area, (1/2 mile away), closer to the source of the RFI have lost the entire HF spectrum. See the movie above. Hit play, and all looks well until about 22:30 GMT, which is about 3:30 PM in my local time zone. As you can see, the RFI goes off scale at that time. The S Meter reading for that signal is around 10 db over S9. It is also affecting three other hams in the area. One poor fellow is so close to it that all ham bands are wiped out, 160 Meters through 10 meters are unusable during this time frame. There is another ham located about 1/4 mile from the source, he has just moved in, and was unaware why his use of 40 meters was precluded due to RFI. So there are folks who have it worse than me in this! Note this is an older recording, currently the start time for the RFI has changed to 01:36, or 7:36 PM local time. All in all there are 4 and possible 5 hams affected by what is a single source, over one or two square miles, all from a single source. We have the general area pinned down, and this summer, (2014), we are going to locate the house, and either contact the owner, or request FCC assistance. Continue reading
Review of West Mountain Radio’s RIGrunner
What this means is that the device has the Powerpole connectors pointing horizontally out of the side, as opposed to pointing up out of the device. I was going to mount my RIGrunner 4008H on the side of a vertical desk support, and I wanted the power cables pointing downwards, and not out towards the wall behind the desk, so the H model was the model of choice for me. As can be seen from the photo at the left, the H version did exactly what I needed. I wanted to move the desk as close to eh wall as possible. I also wanted a pigtail so I could add ferrite snap on cores for RFI suppression to each 12 VDC lead.. All of this just screamed downward pointing cables. Hence the choice of the H version, so I ordered it and it arrived a few days later. Continue reading
Rebuilding the Shack– from scratch
In 2014 I decided to upgrade the station, I became retired in 2013, and my use of the station was no longer weekends, and holidays. I could use it anytime I wanted, day or night. I decided I needed a better radio, and a bit more desk space. After a lot of looking, the Elecraft K3 popped up on my radar. The K3 provided me with a better radio, and a bit more desk space, exactly what I wanted. At the time of purchase for the K3, I decided it was about time to do a station rebuild, starting with the station grounding , and working my way to the Coax, and finally the control lines.

ARRL to FCC: “Grow Light” Ballast Causes HF Interference.
On March 14th, the ARRL published an article stating: “ARRL formally complained to the FCC, contending that a “grow light” ballast being widely marketed and sold is responsible for severe interference to the MF and HF bands”. Continue reading
Review of Ameritron’s AL-82 Amplifier
After several years of use, this review of Ameritron’s AL-82 amplifier seems in order! I have owned the AL-82 for three years now, and it has given me incredible performance on all bands. This review will not be a technical review, it will be a general observation, and usage review… Does the amp hold up, does the amp work, does it run hot, etc., that sort of review… Continue reading
Review of ‘The Daily DX’
DX News is just what it says, news about current DX activities. Bernie McClenny, (owner of The Daily DX, and W3UR), combs the internet looking for DX news. He then aggregates that news into this section. I suspect he has contacts into the DX world mortal men do not, as I sometimes see info there I see no where else… Bernie does edit the ARRL’s How’s DX column for QST, so he is in the know about DX. Here is a short cut from the News Section of The Daily DX: Continue reading
Review of N3FJP’s AC Log 4.x
One of the best logging program available just got better! Scott Davis, (N3FJP), has announced his completion of the rewrite of the popular logging program called “Amateur Contact Log”, version 4.0 from Visual Basic to the C# language, moving the version number from ACL3.4x to ACL4.x. See my review of ACL3.4 here. Continue reading
