I have been looking at a way to get a Yagi on my roof. No room for a big tower at my QTH, but something on the roof is within reason. I have been looking at the Glen Martin Roof Towers, particularly the smaller Glen Martin RT-424 Roof Tower. It is a 4.5 foot tall,... Continue Reading →
DXDUSB – DX Doubler USB Interface Update
DXDUSB Development Status I have had some requests to provide DXDUSB prototypes to couple people. The latest prototype (Protot3) is still very rough. I have a couple in ongoing testing and they seem to be working well. However, these are very rough - assembly is hand soldered wires attached to the Arduino board. While I... Continue Reading →
A USB Interface for the DX Doubler – The Last DXDUSB Prototypes
I have been working on a USB-only interface for the Top Ten Devices DX Doubler for some time. I recently completed the 3rd generation prototype. This is still a prototype - it uses a very small Arduino board with attached wires, but it is shoved into a nice small Ethernet drop-box enclosue. This version has... Continue Reading →
VA QSO Party 2016 – Two for the Road
I went mobile again for the 2016 Virginia QSO Party, using the callsign KT4KA. I use that callsign so as not to confuse everyone when calling CQ (with my normal "3"call). The goal this year was to beat last year, and hopefully win the Mobile all-Band category. No matter what happens, this is always enjoyable.... Continue Reading →
It Really is all About Antennas
As I try to continually improve my Station, I keep coming back to the antennas. I have a couple very nice Radios, but I am still not very competitive in Contests, especially DX contests. I have always used mainly wire antennas and generally if I can hear them, I can work them. Now I know... Continue Reading →
VA QSO Party 2016
I plan to go mobile again this year for the VA QSO Party in March. This is an enjoyable contest with lots of activity. You will probably see every County and City in the State activated at some point over the weekend. I will be using the callsign KT4KA/M so as not to confuse people... Continue Reading →
Arduino Pro Mini – A Great Tiny Micro Controller
If you have been working with Arduino boards, you may already know about this great little board. The Arduino Pro Mini is about 1.7" X 0.7" in size. It has the normal 14 Digital I/O lines and several analog inputs as well. The one thing you need to know is that you must have a... Continue Reading →
ARRL Triple Play Award – One Worth Having
I just saw on the ARRL LOTW Web Page that they have processed my application for the ARRL Triple Play Award. I do enjoy Contesting but otherwise I do not spend much time chasing awards. The Triple Play Award, if you don't know, is for confirmed contacts with all 50 States on CW, Phone, and... Continue Reading →
DXDUSB DX Doubler USB Interface – 2nd Prototype
The 2nd prototype of the DXDUSB Interface has been completed. I ran it hard through the recent NAQP CW contest, and it did very well. Now it is just a matter of finalizing the software (of course software is never really "final"). Here is a look at the 2nd prototype Next i will be designing... Continue Reading →
RTTY with FTDX-3000 and MMTTY
I have finally gotten this setup working fine and decided to save all the details. You can find a description, along with all of the screen TABS from MMTTY set to get this working on the Digital Modes Page on this Site. Good Luck! Here is how it looks once I got it all together.
