Re: [IRCA] TA's found inside BOG last night + Questions

["HASCALL, DAVID CIV DFAS" <DAVID.HASCALL@xxxxxxxx>]

Gil,

I'm no antenna expert but - could you put a small pre-amp on the EWE to
boost the signals?  I had a Sanserino box loop about 25 years ago that
came with a small (2 transistor, IIRC) pre-amp.  The box loop itself
pulled in signals at an "okay" level on its own but once I flipped the
switch on the amp, it came to life.  The little hobby box that contained
the amp and 9v battery holder, also contained a dual gang (?) variable
capacitor to tune the loop and a switch for the 2 MW ranges.  I guess an
amp for a Ewe, Flag or whatever wouldn't need the tuning pieces / parts
just the amp.

Question for the entire list:  Where can one pick up a small pre-amp
like that?  If not commercially avaialble how much $ would it take to
have one built?  I'm a techno-klutz.....

I still have the loop, it is burried somewhere in mom's basement.  Maybe
I'll grab the amp, next time that I'm over there to see what is under
the hood.

73,
Dave in Indy

Kaz,
Thanks for the suggestion and heads up on the Africans.
Through serendipity I learned that aiming directly at DX with a receive
antenna is not always the best choice and that lack of noise can be more
important than actual gain.

My EWE's beam is directed 130 degrees. My home is 13 miles from the
coast
and the ewe fires perpendicular to the coast.  This is the only
direction I
am capable of at my qth because of lot size and suitable trees.  It  is
deadly for the Caribbean.  It is super quiet.  While I have not picked
up
any European or African MW stations with it, in the late fall and
winter, it
murders the LW broadcast band despite it firing 90 degrees perpendicular
to
the average bearing to Europe.  My lobes lie parallel to the Eastern
Seaboard with excellent rejection towards the back which is most of the
US
mainland.  A portion of one of the lobes cover's Europe and Africa,
although shrunken from ideal.  It's the quiet nature of it that makes
the
difference.  Perhaps I should try for Benin, Sao Tome and Mauritiana at
your
suggested times.
73 Gil
