Re: Elecraft Digest, Vol 176, Issue 32

Eric,

It would be much more clear what you are interested in if you would trim
to the item of interest rather than copying the entire digest.
I am not the moderator, but I could not make heads nor tails out of your
posting.

Apologies for the mis-sent email!

I *meant* to send it to the original sender.

...and to think, I'm the administrator of a large list -- I should have
been more careful.
