After the building frenzy that resulted in the completion of the 40M WBR regen, I was left with another entirely functional WBR on Board #2. This one consisted of the beautiful AF Stage v2, hooked up to the funky but … Continue reading →

Late breaking update 12/14/2014: With the help of some folks on the SKCC sked page, the Mighty Mite completed not one, but two QSOs this evening! Both with stations in Tennessee, KC9W and KT4TN, both operators coincidently having the first … Continue reading →

The Michigan Mighty Mite – oscillating, not liberated.

Posted on December 4, 2014 by n2htt

I have been in the throes of some serious building recently. The DFR (see previous post), a nearly completed WBR regen receiver, and now, suddenly, without warning, in two evenings, a Michigan Mighty Mite QRP transmitter. Soldersmoke is one of … Continue reading →

Update: a feature article on the DFR was published in the November 2015 QST  – check it out! It’s been a while since I have made a blog post, but I have been busy with a number of building projects. … Continue reading →
