Multiband Antenna Switching

When I first started on this project I think my goal was to “magically” handle SWR on several bands and my area of focus was on using an UNUN or Current Choke to do so. They did do what they were supposed to – to a point, but there was no “magic” there. They did bring the match “close” to the range of the…

Mission Accomplished!

The switched transformer Inverted L matching circuit works as designed. The biggest take away is that now I can run full power on 80M, which was the biggest challenge. This morning I woke up, came out to the shack and did one last test and found that the 160M position was not isolated when I was switched in position 1 and 2 – so…

Dios de los Muertos

Yesterday we had the best Halloween party at Credit Karma. I felt like a kid again – kudos to our wonderful Events Team – they knocked the ball out of the park!. What an amazing company to work for – I’ve been at CK for 8 months and just love it. The Inverted L with home brewed remote tuner at the base has a…

The Best Two Antennas I Have Ever Had

For all low bands, 160-30M, my own designed “Modified Bobtail” is a very clear winner. I’ve blogged extensively about this antenna, and the best antenna tuner for this antenna – and my favorite antenna tuner of all time is the Palstar BT1500A. Every feature, knob and button is useful and perfect for the Mod Bob. The best yagi antenna I have ever had was…

A Funny Thing Happened on the Way to the U.RAT . . .

OK, so that’s a bit dramatic – but I’ll be busy first wrapping up the final “packaging” of the u.RAT Demonstration Board, and then writing articles and presentations. I will submit the article to QST with the main theme one that I will repeat at EBARC and Pacificon – which is that the “Maker – Ham” connection is a real force to be reckoned…

So, How Does The Remote Palstar BT1500A Perform With The KY6R Mod Bob?

I have been told by The Mission Trail Net that my 75M signal has never been better – and quite a few people said “Are you in my driveway, what did you do?” . .  I tuned the Mod Bob manually this past weekend on 75M, which is a band that my Elecraft KAT-500 could tune but where the KPA-500 only tolerated about 200…

Raspberry Pi Communicating With Arduino Uno

http://www.instructables.com/id/Connect-Your-Raspberry-Pi-and-Arduino-Uno/ Arduino boards are great to dedicate them to one function. In my immediate “use case” I want to have a control box that supplies power and has two knobs to control my remote antenna tuner. I might even add a little LCD to give feedback from the tuner – like what offset the L and C Stepper motors are at. If I were…

SPE Expert 1.3K-FA First Impressions

I wasn’t in the market for a new amplifier, but when looking at the new Elecraft KPA-1500 (and realizing the price would never get board approval), I looked at competing products and found this one. I read the reviews, looked at the price, and as soon as I sold my old car – I ordered one. First of all – its a dream footprint…

The KY6R “Favorite / Essential Gear” List

My all time favorite rig is the K3. I’ve owned my rig since 2008, so its by far the longest I’ve had one rig. Its what got me to Honor Roll and even after all these years its still seems like quite the performer. I also love my KX3 for portable work, and previously loved my Ten Tec Orion II, but I will keep…
