Palstar BT1500A Schematic and My Switching Arrangement

I’m not exactly sure I understand how to read this schematic, but for all bands, the relay switching that I have going on is >50 ohms, LP or the UP position(Hi-Z) -which by default has the 65 pf engaged at the output – and then the Low C, where the larger 960 pf capacitor is taken out of the circuit. The resulting circuit looks…

Remote Controlled BT1500A Part 3: All Wired Up

The tuner is mounted in its waterproof gasketed box and has been tested to make sure the SPE 1.3K can work with it. The answer is Yes. I said “servo” in the video but meant stepper motor. Anyway, that’s the next big half of the project – getting the stepper motors working and installed. In the mean time – its easy enough to go…

Field Day

Wow – I’m having a big ham radio and maker weekend. This is exactly what I have needed to re jump start my hobby. I almost stopped blogging because after I “made the grade” with Honor Roll and DX-pedition of the Year goals in the bag, I really thought that I was done. A few years ago I tried to get into Arduino, but…

When Art Meets Science

Some fun with Arduino and a small servo motor – the “prelude” to the Stepper antenna tuner . . . I’m obviously having too much fun!

Summer Solstice 2017

An art piece I made years ago – but that still depicts how I feel about the (northern hemisphere) summer solstice. This week – until this coming Sunday is the “week of the longest days of the year”, and starting Sunday, we start losing daylight minutes. This is of course what low banders like – each day another day towards more darkness and longer…

KY6R Summer Project: Arduino Stepper Motor Driven Palstar BT-1500A!

K8AC’s wonderful balanced antenna tuner with stepper motors and controller K8AC Control unit http://www.k8ac.net/BalancedTuner.html One of the coolest projects you can do in ham radio is automate an “analog” or manual antenna tuner. I just bought the Palstar BT-1500A, which is a balanced tuner, and I fully expect that it will be great on 160 – 30M with the “Mod Bob” antenna that I…

Guest Blogger – Mike Coffey, KJ4Z

The absolute BEST thing about working on VK0EK was making new friends and sharing in the success of the project. Mike is a forward thinker and the master mind behind the VK0LD Remote operation, and he also worked very hard behind the scenes – on the OQRS system, networking and the satellite gear, and many other critically important behind the scenes tasks and programs…

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…

Be the Change You Want to See in The World

On Friday, I sold my car and now we are a one car family. I’ve wanted to do this for many years, and the whole hub bub regarding the Paris Accord made me finally do it with conviction. I also had an epiphany after toiling over the nasty political climate in the US. I kept reminding myself what I was taught in the Episcopal…

The Top Band Chordal Hopper

I had a blog that ran for years called “The Armchair DX-er“, and it basically ran its course. The idea behind that blog was mostly my ham radio road to DXCC Honor Roll and also my personal involvement with the 2016 VK0EK Heard Island DX-pedition, but that chapter of my life is done, and that blog had years worth of “cruft” that I did…
