On the morning of August 4th 2020, a Tropical Storm passed through the Northern Neck area in Virginia. The storm sent an EF-2 tornado through our area in White Stone, starting in the Windmill Point area and traveling about 15.5 miles, passing by Kilmarnock. The tornado missed our house by about 1000 feet, but put... Continue Reading →
160 Meter Inverted “L” Antenna – Updated 9/1/2020
I have a need to get on 160m occasionally for a contest, but have limited space. I tried a dipole, but it was just too much trouble. I had to bend the ends all around to fit my small lot. I keep hearing that an Inverted L is a decent antenna, but have never been... Continue Reading →
Loop-on-Ground, the simplest Receive-Antenna you will ever Build, and it Works
I have been experimenting with some Receive-antennas for the Low HF bands (80 and 160 meters is "low-band" to me). I discovered these popular antennas from other Hams at the Contesting Club (Potomac Valley Radio Club) I belong to. Nearly all the serious Contesters in PVRC, and all of their Superstations, have Receive-only Antenna options... Continue Reading →
Your Elecraft KAT-500 Tuner Protects your KPA-500 Amp – until it doesn’t – UPDATED 10/30/2019
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 way to interconnect the IC-7600 with the KAT/KPA-500 so that the Amp would be protected...

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 separate 12 volt power from my Station power supply for the Tuner. Only the Tune... Continue Reading →
LOTW now has 1 Billion QSOs!
I just saw that the ARRL Logbook of the World (LOTW) now contains records of over 1 Billion QSOs. That is impressive. When it started, I wondered if it would survive. It went through a period of slow-response, although I am not aware of any actual lost QSO records. Now it is mainstream. If you... Continue Reading →
Using the KAT-500 and KPA-500 with Icom Radios: Part II – Updated 2 AUGUST 2020
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 Elecraft KPA-500 Amplifier and KAT-500 Tuner. It appears that there are several different ways to... 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 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 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 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 →
