There is a country, which I will allow to remain nameless, that receives a lot of “off-shoring” of software engineering from US companies. I teach a fair number of engineers from that country and, for whatever reason, I have to say they seem to be grossly under qualified. By and large, in the classroom they ask few questions – that could be a cultural thing, I admit – and in the labs they have more problems than others in following the detailed instructions – again, that could be a cultural issue.

Regardless, the 40M and 20M dipoles are now installed in the attic. I left a little slippage so that, hopefully, tuning of arm lengths can be done at the feed point – I sure don’t want to crawl out to the end points again. [Phew!]

Residence Antenna Plan

My wife and I live in Phoenix Arizona. Our house is situated on a nearly square 1960-sized residential lot. I mention the year because city lots have shrunk in the past couple of years and our 100x105 foot property might seem large in some areas these days.

After many years of inactivity in ham radio, I decided to “go all the way” (while I still could) and get my Extra Class ticket. So in the middle of 2009, I bought the ARRL’s Extra Class study guide and started on page one.
