I recently purchased an unbuilt OHR-100A, a popular monoband QRP kit first offered by Oak Hills Research in the 1999. This one is for 20 meters and looks to be a real gem.
Included in the kit is the optional 10-turn VFO pot to increase tuning resolution. This renders the front panel VFO dial markings as invalid so I ordered a Freq-Mite from the 4SQRP club which also arrived in today's mail.
There is plenty of room inside a finished OHR-100A to install other options necessary to putting a radio on the air and I'm already considering battery and keyer possibilities.
OHR produced several excellent QRP transceiver kits but one of their most useful kits was the WM-2 wattmeter. I've had one for decades and it still looks and works like new. For those wanting an equivalent (almost identical) analog QRP wattmeter kit, click here and scroll about halfway down the page.
OHR was founded by well-known QRPer Doug DeMaw W1FB. Following his death in 1997, Marshall Emm N1FN took over and continued until 2020 when he became an SK.
I'll begin the build this coming week.

The OHR 40m Sprint was my first rig back in 1970-something. I regret letting it pass on to someone else late in the last century. Can you search your endless stash of kits and let me know if you have one? :) Best fun with your new OHR!
ReplyDeleteHello Bob - no, I've never had a Sprint but I know they were popular back in the day. The one OHR kit I regret never building is the OHR-500. Of course now we have the QMX+ covering 9 bands and all modes at 1/8th the size and 1/3rd the price. Still...if I ever see an unbuilt '500 I'll snap it up.
ReplyDeleteAnd I'll keep my eye out for a Sprint for you.

A bit confusing: OHR made both a Spirit and a Sprint. And a Sprint II.
