KD5SBI and the Unified Microsystems SCI-6

I've been offline for a while because of ApolloCon, but I'm back at it. My XYL, KD5SBI, has expressed a desire to do PSK31 on 2-meters FM (and I've confirmed that there is such a thing) and has indicated that she understands the need for an interface box. To that end, she suggested that I purchase the UMI SCI-6 and assemble it, for it is a kit, for her birthday, which is coming up soon.

Ascension Island on the Air This Weekend

This weekend G4DBW will be on the air from Ascension Island as ZD8RH. Details here.

Update on my FT-102

Last night, Dr. Mal Eiselman and I spent an hour on the phone going over my radio and the news is pretty uniformly bad. There is no loose connection or anything that I'm confident I can fix in the radio. The problem is that the local oscillator board is not working. So, it's back to the good doctor for repair.

The one bright spot is Dr. Eiselman whose efforts to assist me are much appreciated even though they were ultimately unsuccessful. I can definitely recommend NC4L as the guy to fix FT-102's.

DXPedition to Curacao

ON6DX will be in Curacao from June 28, 2013 to July 7, 2013 as PJ2/ON6DX.

Compact antenna update

I am attempting to create whole-band antennas for 80m and 160m that will actually fit on my yard. NEC2 says that a particular design will definitely work, but having built a 10/12m scale model of the larger antenna, well, it doesn't work. I'm going to be investigating why. I hope it is because I made a construction error.

My Yaesu FT-102

About a year ago, on March 30, 2012, an acquaintance of mine, Don Culbertson K5LDD died. Although he had had cancer, my understanding is that he died of a heart attack. Since he had been sick, he had discussed with his wife who was to help her dismantle his ham shack, their home network, and various related things, and the person that he suggested help her with it was me.

XR0ZR DXPedition to Juan Fernandez Island

XR0ZR will be QRV from Juan Fernandez Island sometime in late 2013. The Web site http://www.juanfernandez2013.com/ is under development. It's got a countdown on it now that ends on July 27, but I expect that it'll be updated as soon as there's something to put on it.

Juan Fernandez Island is in the South Pacific off the coast of Chile. http://en.wikipedia.org/wiki/Juan_Fern%C3%A1ndez_Islands

Antenna stuff, but not "Dipoles part 2"

A while back, I complained that I had misplaced my second copy of the Jerry Sevick's The Short Vertical Antenna and Ground Radial What I was trying to do was simulate one of the antennas that he had put in the book to see if I was getting a handle on NEC2. As an aside, I don't use EzNEC because I usually run Linux at home, not Windows, and EzNEC is pretty seriously a windows-only thing. I suppose I could get it to run under WINE, but I'm not really very interested in paying money for a product that could be rather difficult for me to use.

The K9W DXpedition to Wake Atoll

In October, 2013 a group of operators is heading to Wake Island for a DXpedition. See the details here

The Dipole Antenna - Part 1, Introduction

An antenna is an energy conversion device. It converts electrical current to and from electromagnetic radiation. I've been thinking about how antennas work for a while now, and I've been meaning to write down some of those thoughts. This has been driven, in large part, about questions that I had about why you could use a center fed dipole on the fundamental frequency or the third harmonic, but not the second harmonic.
