$2 a large can on sale. It will attack some types of plastic so
you have to be careful, but it's an excellent flux cutter
and degreaser, and leaves no residue. I use it with all
of my electronics work.
- Tonight I soldered up the second of two zero beat indicator boards I
had bought, but this time I used some of the .020 solder I bought for a
recent surface-mount project. The second board was virtually flux free
compared to the first board where I had used .032 solder. I think I
found my solution!
Looking forward to getting to work on the ATS-3B!

is much easier to control the amount applied. It makes for as much
neater finished project. This is especially true for SMT work. Since
goind to .020 several years ago, I only use my .031 for 'heavy duty
applications like cable connectors and the like. ALL pc board work
here, thru-hole or SMT is done with .020 or smaller.
Also, for those of you who frequent hamfests- If you don't already
have a lifetime supply of smaller guage solder- It would be good to
keep your eyes open in the flea market areas for good deals on rolls
of solder. As Steve's recent experience with Mouser shows, you -don't-
want to have to pay retail prices for it. At one local hamfest a
couple of years ago, I was able to buy several rolls of .020 and
smaller for cheap.

I actually finished my 3a this afternoon with the winding of the 80m
coils. Boy, are my hands sore! ;) Mine actually receives quite well
on 20m so far and the frequency announcement is spot-on. I still have
the alignment stage to go (and casing), but everything is working out
