Not sure what "number of hams" chart you're looking at, but the "numbers" are going up not down. March 2007 - 655,048 March 2009 - 668,307 For more statistics, go here: http://www.ah0a.org/FCC/Licenses.html Pete, wa2cwa Dayton Spaces 1960-1961 On Thu, 30 Apr 2009 20:49:21 -0500 Dave Mayfield W9W

Isn't one of the primary points of Amateur Radio to provide communication sevices when none exist? Seems like they have a need, and good reason, and are going about it the right way. Any time someone expresses an interest in Amateur Radio, we ought to always show our best side, wether we ag

I mentored a two couples back in the mid-70s who were wanting their ham tickets for retirement. Both couples had purchased sailboats and planned to spend their retirement sailing from one port to another. They explained the main reason for the ticket was for emergencies and to get weather inf

Look at it this way, these types of people getting a ham ticket are not in most all likely hood going to become serious hams, but they do count in the numbers game. So I would rather have their numbers than not, in case you have not noticed the numbers of hams is going down not up. While I agre

This may be an unwarranted alarm but if it were me, I would increase the value of the RFC in the bias line from 100uh to maybe 1mh. Your resonate frequency with the .02 bypass capacitor is quite low but I suspect a substantial amount of RF current will still be passing through a 100 uh coil and
