I now have the Elecraft KAT-500 Antenna Tuner and the KPA-500 Linear Amplifier. My rigs are not Elecraft, but Icom (7600 and 7300) and Yaesu (FTDX-3000). I want to setup the Station to use the Elecraft components with my non-Elecraft transceivers. Since the KAT-500 has connections for the Icom AH-4 antenna control interface, I will...

Using External Antenna Tuners with the IC-7300 – Update 9/24/20
I have been trying a couple external Tuners with my IC-7300 transceiver, with mixed results. They actually both worked, but operation is a little confusing. The tuners I have tried so far are: Elecraft KAT-500 LDG Electronics IT-100 The Elecraft Tuner is made for the K3-line but Elecraft has also made sure that it can... Continue Reading →
IC-7300 Spectrum Display with N1MM+
I recently bought an Icom IC-7300 SDR transceiver, and finally got a chance to start looking at it. My hope is to use this as a Mobile rig, although it is a bit large. Not sure how I will mount it in my F-150 yet, but I will give it a try. Since I have... Continue Reading →
Moving the DXDUSB inside the DX Doubler
I have been using the DXDUSB as the interface for my DX Doublerfor a couple years now, and what I really wanted to do is to have a DX Doubler with the USB interface "built-in." Well, the idea of actually working the DXDUSB into the DX Doubler design died when they decided to pull the... Continue Reading →
Sure I Like SDR Technology. But I still Want a “Radio”
I have worked in an industry where we have been developing "digital radios" for many years. Many of the technologies that are finding their way into the great new fad we all call SDR (Software Defined Radios), are not new. What is new is the hardware that makes it feasible to produce small, lower-power, affordable... Continue Reading →
AntDecoder Proto Testing with 2X6 Switch
This weekend, I finally got a chance to assemble and test a prototype PC Board for the AntDecoder. The board and the software worked fine. The only issue is that I need to add output buffers to the Arduino lines that drive the two BCD ports for the Antenna Switch. The switch uses 12-volt logic... 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 enough to provide the switch at minimal cost and also has supported this effort with... 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 Antenna Configuration table: Alt-F9: Fix issue with 1.8 and 3.5 in Antenna table when country/locale...

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, and added access to the 5 MHz Band using the Band buttons on the front... 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 Loop antenna for some time. My main use for it initially will be as an... Continue Reading →
