> Finally got back on 160 tonight after a long absence working on my

> little else other than mostly completing that, then making copies.
>   I heard the very end of a European signal on 1831.7 tonight with a
> 579 signal around 0335z (it was probably DK5PR).  The amp was turn on
> and I ran off to finish a video dub.  Back at 0345 I didn't hear any
> DX and so decided to CQ.  DJ7MI came back--he was 359, but with my
> seldom used since shortened Beverages I had a hard time trying to copy,
> find the best antenna and tune my MFJ-1026.  IT9ZGY called just after
> and I had more time to experiment.  Two Beverages feeding the filter
> produced the best copy (not perfected until after listening to his
> CQing later).
>   ZS6UT called at 0425 and I started to get the hang of things again--
> this time the transmit antenna (3 active element parasitic vertical
> array) was best for receive.

>   I'm finally back to trying to figure out the prior mentioned
> Umbrella Antenna.  If it wasn't the April 15 issue of Radio World
> (and they had an April 1 edition already) I would wonder...  I forgot
> to mention the authors:  Clarence M. Beverage, president of Communi-
> cations Technologies Inc. and Alan M. Christman, a professor of
> Electrical Engineering at Grove City College (PA).  I couldn't
> learn much about them from a brief internet search...  I found SOME
> of my 1987 NAB Engineering Conference Proceedings book (indirectly
> mentioned).
>   If I can get myself up early enough, maybe I can start trying for
> some of that morning DX as well.  What do they say...  It's not over
> until the fat signals stop singing!
