Hello Art,
No matter what we do, there will always be people that just don't
understand us. People who think that "that ham over there" is the cause of
all their problems, real or imagined.
If we worry about what our neighbors might think, it'll simply detract from
the perfectly legal right --and
Thanks for all the input on this. I am pretty well set up to do non-sync'd
diversity. I need to improve antenna switching though.
My 2.5 acre suburban lot seems to be getting smaller and smaller, while the
neighbors are increasingly convinced that I am nuts.

Early in 1925 Radio Corporation of America station 1XAO had one near
10 mile long wave antenna. In 1926 they had three spaced 6 miles each.
Harold H. Beverage discovered diversity reception when switching
between antennas. When the signal was fading on one, it could be
peaking on another.
I can't imagine doing a 160M contest WITHOUT dual receive. With 580ft
two-wire Beverages at right angles, and a foot switch to reverse both of
them, I can easily hear in a 360 degree arc: listen 1-2 sec NW and SW, step
on switch, 1-2 sec NE and SE, call CQ, repeat. When it's pre-dawn, I

I operated the entire Stew with a 160m 4-square antenna, with no
listening antennas. One hand on the keyboard,
one hand on the 4-square directional switch. After every CQ, if a
signal was not heard using the xmit
direction, the switch was rotated through the other positions to make
sure

The best station I have ever worked was K9DX when he had up his arrays

Pay attention to everything Eric says, and take a look at his web page
showing his RX antenna farm. Eric consistently has the best ears on the
band! In the 4-5 years I've been working QRP on 160M, only once has Eric

Add me to the list of diversity operators. I typically have one beverage
in one ear and some other directional antenna in the other. For the Stew -
this was a 1200 foot beverage towards the East coast and a Hi-Z array (4

At home I use a foot switches to cycle between three receive antennas after
each 160M CQ: NE and SW on a K9AY loop, and WNW on a west-facing pennant.
Each antenna is fairly broad in the forward direction although they have
deep deep nulls in the backwards direction. Oftentimes 8's will come in
best
What I have found to work well is taking advantage of a radio with dual
receivers, not necessarily "locked", ie. diversity as in the K3, but at
least on the same frequency. The main RX is fixed on the "hot"
direction at the moment, whether that be "NE" during EU peak hours or
"W" after EU sunr
Hi Art,
I have 2 classes of rx antennas for 160/80, an active rx 4-square with
short 108" verticals (a copy of the first-generation DXE array) and 3
pretty long bi-directional beverages. In general, the 4-sq is not as "razor
sharp" as the beverages, so I generally put the 4-sq on the main rx of th
Do any of you wish to share your methodology on using directional receive
antennas during a run?
The inverted-L was way too noisy with the lightning static, to hear weak
and distant stations.
On the other hand, I am sure I missed some stations, by being on the
wrong-direction receiving antenna at
15 matches
