\"\"<\/a>Hi Bill,<\/span><\/p>\n

Attached is a picture of the remains of my transmitter, “The Super Duper X Spy <\/span>Transmitter<\/span>“. My little rig didn’t sit around; it made QSOs the day it was finished, 41 years ago. Since then it has bounced around in various junk boxes and had some parts robbed for other projects but thankfully it’s still mostly intact. <\/span><\/p>\n

I constructed it based upon the original article in Ed Noll’s book, “Solid State QRP Projects”, pg. 51, Project 17, “10 160 All-Band Two Watter”. That transmitter was later to become known as the <\/span>Michigan Mighty Mite<\/span>.<\/span><\/p>\n

My MMM (or SDXST if you will), features a built-in relative power detector, a microswitch key (upper right-hand corner), room for an internal 9 Volt battery and a jack for external power. The jacks are each different; a BNC for the antenna, a 3.5 mm closed-circuit jack for the key, a 2.5 mm for the relative output meter and a phono jack for the external power. My notes say that I added a .1 uF Emitter bypass and that it increased the power output by 50%. I also used a toroid for the output tank instead of the 1-3\/4″ coil form called for in the article. Use of the “Sucrets” box was not my idea; I got it from one of the ham mag’s. of the day, probably 73.<\/span><\/p>\n

Your coverage of those little rigs has motivated me to restore mine and make some QSOs for old times sake. With, of course, the proper output filter :-). I’ll send a picture of the ‘guts’ when it’s finished.<\/span><\/p>\n

Thanks Steve. Great stuff. But… WHERE’S THE OUTPUT FILTER?
