I have been using an Elecraft KPA-500 linear amplifier and a KAT-500 Antenna tuner with my Icom radios (mostly the IC-7600 and briefly with the IC-7300) After much research and discussion, I figured out what I thought was the best... Continue Reading →

Can’t Use TUNE Button on IC-7300 with KAT-500 Tuner

When I initially connected my IC-7300 to my Elecraft KAT-500 Antenna Tuner, I was unable to get the Tuner to start Tuning the KAT-500 from the TUNE button on the front panel. Here is what I discovered: I was using... Continue Reading →

Using the KAT-500 and KPA-500 with Icom Radios: Part II

I have continued to investigate the various ways to connect my Icom IC-7300 or IC-7600 to the Elecraft KAT/KPA-500 Tuner and Amplifier. I have received some very helpful communication from a number of other Hams using Icom Radios with the... Continue Reading →

Using the Elecraft KPA-500 and KAT-500 with Icom Rigs: Part I

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... Continue Reading →

Using External Antenna Tuners with the IC-7300 – Update 3/2/19 (Elecraft section)

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... 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... 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... 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.... 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... Continue Reading →
