The vactrol control voltage on the Wellbrook K9AY was fed via the coax. 
feeder. Two separate wires were used to switch the loops and beam reversal 
relays.


The rare Wellbrook K9AY Phased array used a fixed 360 Ohm termination 
resistor. The pattern tweaking was done by varying the Phase/Amplitude.

Colin & Craig -
Principles don't need to be similar - a Vactrol can terminate  a Beverage, 
DKAZ flag, loop, delta, etc.

Are you really using a flag or is it a corner fed loop?
And yes, the K9AY system uses a termination box with a Vactrol. The 
Wellbrook version had several flavors, but the one I remember also used a 
Vactrol but unlike most other schemes, DC was fed to the Vactrol via 
separate wires rather than using the coax to carry DC. Can you be specific 
about the version you have?

Entirely possible - but I am not an authority on the K9AY --
Principles are similar I think -

I am going to post an article on the subject and open up a discussion area
on the DXer.ca website.

Also looking for a sense if there would be a demand for separate hand-made
VACTROL units
that can be used be the deliciously simple FLAG antenna system/concept.

Sorry, I forgot to mention that the antennas are in the planning stages. I was 
planning on putting one up either this weekend, or next. I haven't fully 
decided between a corner fed loop vs a flag. I'm also wondering if a 
bidirectional loop, or flag would work with two wires fed at opposite ends.

Thanks for considering my questions.

I use a 47' wide, 25' high Flag with a Wellbrook FLG100 North American Flag
head amp
and a modified version of Mark Connelly's variable resistance/termination
controller featured on

http://www.qsl.net/wa1ion/flag/flag_antenna.htm

In shack control BOX and At Antenna Termination box -

The difference is - I use a separate pair of wires to feed the variable DC
to the antenna termination box.

2015-09-15 Thread R. Colin Newell 
As Nick and Gary pointed out today's lack of excitement was
the result of a sunrise crap shoot with no shots fired.

Started with promise at 1314 UTC with 529 SQM at good levels from Alaska

It quickly degenerated into an all top tier Japanese sideshow with the
usual suspects...

1315 - 594 khz - Japan YL / OM back and forth in JJ

1318 - 774 khz - Japan - YL in more English sounding than usual

1319 - 828 khz - Japan - OM in JJ

1328 - 1566 khz - Korea at good levels at times with pipe organ music

1330 - 891 khz - EE talk with lively music over top of 890

1336 - 675 khz - Assume New Zealand with Kiwi style cadence of EE

1343 - 612 khz - Assume 4QR with EE Sports talk

Hints of audio and occasional appearances of clear audio on
567 (JJ), 585, 756, 972, 1053, 1116...

Good carriers and undelivered promises of audio, 531, 558, 621, 747, 792,
855, etc , 1575

A pot of Ethiopian coffee brewed at 1400 UTC made up for the embarrassing
debacle
that was this mornings session.

1st day using a VACTROL on the N/NW Flag from schematics provided
by Mark Connelly in Maine and strict supervision from Nick Hall - Patch
and mich encouragement from Walter Salmaniw.

I plan on making plenty of VACTROL sets for Flag antennas if anyone is
interested in one. It allows for the remote control of the termination on
the
flag using an opt-isolator.

Good DX everyone!
