A Diary of Technology Persuits

Trying a “Short” Beverage Antenna on 160m

I wanted to do something to improve my Station performance on 160m, so I thought a Receive Antenna would be the way to go. Everyone tells me that you need a decent RX Antenna for 160m, because you can not... Continue Reading →

Getting into the Game on 160 meters

I have slowly been adding 160 meter Band capability to my Station, mainly in some recent contests. With sunspots so low, and the high HF Bands suffering badly as a result, this seems like a good time to do some... Continue Reading →

AntDecoder Testing and Logic Levels

I have been asked about the progress of the AntDecoder project. I have been working with a prototype PC board along with a 2X6 Antenna switch. The antenna switch is a homebrew model made by Mike, K4GMH. Mike was kind... Continue Reading →

Important N1MM+ Antenna Config Changes

I just installed the latest version on N1MM+. I have been looking at using the Antenna Data provided by N1MM+ for controlling my antenna switching. In the latest version, the Change Log shows two changes that were made to the... Continue Reading →

Updating FTDX-3000 Firmware

I finally decided it was time to update my FTDX-3000 to the latest Firmware. Yaesu has been good about making updates available for this Rig. Recent updates have greatly improved the spectral display including adding a nice waterfall below it,... Continue Reading →

Hints – Using the ICOM IC-7600 on RTTY with N1MM+ and MMTTY

I keep seeing people having trouble with this setup. Every time I go to RTTY Mode, something is not working. It seems that some of the parameters in MMTTY and in the Radio keep resetting themselves. There are some other... Continue Reading →

Using N1MM+ Serial (OTRSP) Data for Two-radio Antenna Switching

I have been investigating ways to automatically switch antennas in a 2-Radio (SO2R) station for use in Contesting. Using multiple antennas is nearly a must for HF contesting, including Yagis, Veticals, and any of a variety of wire antennas. When... Continue Reading →

First Trial of Horizontal Loop

I installed a prototype 40m Horizontal loop for testing in a recent contest. This was a test to see if a low-elevation loop would be useful for NVIS propagation, as I was trying to maximize the number of close-in stations... Continue Reading →

Trying an HF Horizontal Loop Antenna

I was looking for a new antenna to try this weekend. I will be in the NAQP CW Contest and there will be many stations active across the US, Canada, and hopefully some DX. I have been thinking about a... Continue Reading →
