I've just posted a couple of QST Technical Correspondence items to my
web site. Although published over 20 years ago, they're still relevant
and might be of interest to some of the readers of this group. They a

"On Solid-State PA Matching Networks" - An important characteristic of
matching networks for class C solid state amplifiers, which doesn't seem
to be well known even today.

"Choosing Wire Size for Toroidal Inductors" - Measurements showing that
it doesn't make much difference. But people are still asking.

Both are at http://eznec.com/Amateur/Articles/.

The L network inductor in "On Solid-State PA Matching Networks" Fig. 1
should be 0.5 uH, not 0.5 mH. The correction I had penciled in 20 years
ago was too light to reproduce and I hadn't noticed that it didn't show
up. I've uploaded a corrected copy.

Thanks to John, KD5YI, for spotting the error.
