This does not surprise me. Years ago when the X Banders started signing on, a

Boston Area DXers member Steve Byan was first out of the gate with a Vactrol
scheme initially applied to Beverage termination in 1996. His controller was
successfully used on late '90s Newfoundland DXpeditions. The original Vactrol
he used had a sealed incandescent
I have had 3 or 4 requests for VACTROL sets -
Here is an approximate break down of the main parts which brings
me to the price for a set for those interested.
Aluminum Box (for indoor controller) - $9.00
Binding Posts (for antenna end box) $6.00
Plastic case for outdoor antenna termination box
Yes Redding CA shut off the original AM, KNRO 1670 is left after what I
think was 600 went dark.
WVMI 570 went dark and is now WTNI 1640, in Biloxi Mississippi

I think it was five years. As I remember, after the five year period, the
station either had to revert to its original allocation or move to the X-band
and take the original station off the air. Also, I think that the original
purpose of the X-band was to mitigate interference on the regular
Trying to change the rules you knew were part of the deal at the time.
The real problem here is that the FCC - typically - ignored that part of
the deal - the surrenders were supposed to take place
on a much shorter time limit, although I don't recall exactly what it was.

Good stuff, Mark.
Here's some more "prehistoric" reading with Vactrol details:

concept for FLAG antennas I have been hooked -
Naturally I did not stop at one unit but ended up making around 8 sets -
Each set consists of a "in shack" remote control unit which contains

THANKS so much for all of the constructive input! The idea of super-sized
loops in the desert is great...except for the probability of wind issues at
this time of year.
I s'pect we'll settle on something practical, keeping in mind Nick's
comment; will let you know. Right now the thinking is

Flags Les. Yes, you can get deeper nulls,
particularly on stations that are located off the
main axis of the antenna. I wouldn't be without mine.

I’m running a flag antenna mounted on a privacy fence in my back yard. I live
in one of those dreaded HOA neighborhoods…so I have to hide the wire. Despite
that, I get good performance using a fixed resistor. But I’m always searching
for deeper nulls.
Has anyone used a vactrol on a flag
