OHR 100A QRP Radio Build – Final Thoughts

I finished building the 40 meter version of the Oak Hills Research 100A QRP transceiver.  I also added the internal keyer.

In this video, I share my final thoughts about the build and the radio.

Summary:  It’s a great radio and I encourage you to build one.  The documentation could use some tweaking to make it easier to understand a few of the more confusing steps.  However, I built it without help and it worked right out of the gate.  If I can do it, you can do it!

OHR 100A QRP Radio Build- Part 2

I’ve got most of the (many!) capacitors installed, along with the crystals, etc. The kit is coming along nicely and I’m enjoying it.

My friend Doug Miller (W4DML) says. “Soldering is Therapy.”  I think there’s some truth to that.  When you’re soldering, you’re concentrating so much on what you’re doing that any other thoughts are pushed out of your head.  So, anything that’s bothering you goes away when building something.

Handling any object (like a soldering iron) that is 700 degrees Fahrenheit will cause one to concentrate – or suffer the consequences.

OHR 100A QRP Radio Build – Part 1

I bought the 40m version of the OHR 100A QRP radio last year and it’s been sitting in the box waiting for me to build it.  It’s time.

There’s something about the season changing to Fall that makes me want to build a kit.  I guess I think of Fall and Winter as being the time of year to do my hamming indoors.

I’ll build this slowly over the next week or so as time allows.  I’m not in a rush – but it’s good to have finally inventoried and sorted the parts. Now, if I can just keep the cats out of the room…
