I love ‘Deadbug’ and ‘Manhattan’ construction. Look ’em up, neat way to build a radio.
Lots of people think Deadbug is for ‘quick down and dirty’ construction, and for many it is. But it also produces circuits with an excellent ground and many times better performance because of it. And frankly, Deadbug and Manhattan projects just Look Cool.
So my friend Corey is getting on Six Meters and broke out his old transverter that converts an all mode two meter rig to an all mode six meter rig. Neat. Way back then I had started a similar project that I never completed; a six meter to two meter transverter. Just the opposite of his because at the time I had a six meter rig but not a two meter rig and he had a two meter rig but not a six meter rig …
I decided to go ahead and complete some of the wiring I had left out and realized this booger got dirty over the years. I cleaned it with flux cleaner (alcohol) and it took most of the dust and surface junk and a bit of the old flux, but the copper is still ‘ugly.’
So now I’m in a quest for a chemical, I guess. I tried a fine ‘brush’ on the flux cleaner but I just can’t get between the parts. It would look awful if I did anyway. What I really want is something I can run over the board to clean it a little better than it is but something that won’t hurt those caps …
Here’s some pictures I took from the bench cam at work. You can click on them for a little closer look. They really don’t do the little booger justice, it just looks cool.

Hello again. I would like to share another resource that will inspire, inform, and astound. Hans Summers, G0UPL, is an Electronic Wizard of the Twelfth Degree (see the International Brotherhood of Electronic Wizards Handbook for further information). He has built a website that abounds with inspiration. His projects are visual and functional. He likes to use tubes and will spurn convention to create a visually appealing project. This is art. The amount of information is sure to keep you busy and should be bookmarked for reference. I am interested in his extensive information on Huff and Puff Oscillator stabilizers and identifying crystal parameters. He builds his own test equipment and documents so that we can follow in his path. Several QRSS projects are detailed. I have added QRSS to my list of future projects. Thank you Hans, for sharing a lifetime of experience at HansSummers.com. 73

Resources abound on the Internet. The G-QRP Club located in England is one that I enjoy. If you “click” on their logo above it will take you to the site. They have data sheets with excellent information for the beginner to the advanced builder. The Club magazine, SPRAT, is published quarterly and is full of inspiration. I just received the fall edition and found an article on Weak Signal Propagation Reporting, WSPR for short. There are plans for The SixBox, a very simple 6m AM transceiver. The G-QRP Club is devoted to low power communication. Membership is $15 a year and you will receive four issues of SPRAT. 73
