Old Technology
A few weeks ago I put a bid on an eBay item and picked up a nice hardcover 1989 ARRL Handbook at a good price.
Yes very old technology on two fronts, the circuits are easy to follow but outdated by today's standard and the way things are going with E readers who knows about the future of a book as we know it.
I also enjoy holding a good book or newspaper in my hand instead reading off the screen. Getting back to my purchase the 1989 handbook is ten times easier to follow than my 2005 edition. Most of the circuits and descriptions seem simple. Hardest part might be crossing some of the older parts but with sites like NTE Electronics that should not be a problem. Sometimes the challenge of the drop in cross and getting to it work is the most fun part of the build.
Check out NTE for older and obsolete part crosses and replacements.

Have to admit not much building or radio fun with the holiday season and work stuff but will have some down time next week to play.
Today's the first day of winter, enjoy the season.

Mighty Mite
In the process of getting the parts for my next project, the Mighty Mite build.
This circuit is from the pages of W1FB's QRP Notebook, page 111. The Mighty Mite consists of one transistor and a handful of parts, output power is a whopping 30mW, QRPp. Taking a look over the parts list, most are common items I should have except for the miniature RF Choke, Mouser/Xicon# 43LR225 which is obsolete. There should be a drop in replacement available from Xicon.
The plan is to try and keep all parts as close to original parts list, just for history of Doug DeMaw's Mighty Mite. I did an online search and found a few different varieties of this circuit. Also need to pick up a few crystals if anyone has a favorite source please let me know.
Updates on this build will be posted in a week or so depending on time with the busy holiday season fast approaching.

New You Tube Video
Put up my first video today on YouTube for one of the kits I built earlier this year.
This was a very rough first try but I feel it was not to bad, next one should run smoother. The kit was the Velleman Super Stereo Ear which is a pretty cool kit.
Now if I can just stop saying "And UH" I should be OK.
