To: ham-homebrew@ucsd.edu
Could someone please email the current capacity of 24 AWG copper wire
(stranded). It will be used at 13.8V.
I've looked all over and can't find it. Is there a data book that has
information for "small" circuit components?
Thank you, Ken

This is a common way to get power across a short distance.
Applications include recharging pacemakers, recharging electric buses,
and recharging electric cars. The basic idea is to build a split
transformer.
What distance did you have in mind?

Hi,
I have been interested in the concept of ham radio for a while now
but have not done anything about it except buy a book(and tape) that helps me
learn the morse code. But I am interested in the following things:
1) Getting a ham radio license.
2) Making (from a kit, perhaps) a radio transmitter capable of
transmitting relatively long distance (a few thousand miles).
I have never even soldered a wire to a board. So, I have the
following questions:
Is it feasible for me to attempt #2 above?
How much is it likely to cost?
What should I expect to pay for similar equipment if I BUY it outright?
Are there any pitfalls I am overlooking in attempting to build an amateur
station rather than buying it? In other words what are the pros and cons
for a beginner?
I don't know if this is the appropriate news group for this
particular question, but what is the procedure that I need to follow
for getting the novice (?) license? I do have this book but it is kind
of old.
Well, thanks in advance for all your advice and help.
I would appreciate email responses to : gulu@engpub1.bu.edu
Gulu.

A friend of mine had a similar experience with a HW-101 which was sitting
in a garage in Florida for many years. It was full of dirt and cobwebs. He
took all the tubes out and put it in a dishwasher and washed it then
rinsed several times. After drying, he replaced all the tubes, cleaned the
volume control, etc and the unit fired right up. Don't know if this will
work for you, but it did for WB4ZZB.
