Hi Henry,
The circuit won't work correctly as published. The network in that unit (from
T1 through R2) claimed to rotate phase will absolutely not do so. It will
shift phase 180 degrees, and vary amplitude....but that is all. That's the
major design flaw (although it appears to have a few other design shortfalls
as well).
I'd stick with the ANC-4, or a proven design.

Early in the LEO messages I saw a list of contractor's company names.
Would source please repost that info or send it to me ?

Tree,
Let me put a small note on your comments:
If somebody undertake to do something volunteerly, it doesn't imply that
he/she may do it indolently. If the Volunteer can't do it as it should be
done, then he/she should step aside and leave it for the others.
Regarding the WPX-certificates issue: After reading the "'SOS"-sign for the
unsponsored WPX plaques in the CQ, the local contest club (HG1S aka HG73DX)
wrote a letter about sponsoring the MM-class trophy. It was sent by fax and
air-mail. We haven't received even a single word to our offer.
So, I think the complaints are right in this case.

WAIT A MINUTE!!
Many contests are being administered by volunteers. The FIRST step
you should take if you are upset about the service is to VOLUNTEER
to help out.
I have not yet sent out CW Sprint certificates yet and I think we have
gotten about 5 years beind on the plaques. It is possible that I
will not have the resources available to do them at my new job. I
hope we can find someone to help with this process (it is mostly
automated). I will ask the first person who complains if they are
willing to help.

Message-ID: <199606051226.HAA13336@kiwi.pyrotechnics.com>
Well, I have nearly completed the modifications to my TA33Jr for
DXpeditioning. No Jim, I am not throwing it out for another antenna, unless
you want to send me one, gratus. Many had commented on various antennas that
broke down to various sizes, though, I found out from the airlines, they
would make it into the Caribbean, they would cost extra if going to Bora
Bora. I will summarize the dimensions, splices, etc. as soon as I finish,
hopefully, this weekend. So far, so good. I would not do this to an antenna
that is going to be left up year round. My TA33Jr is an older one, so I have
longer tubing, in some cases. I hope my summary will give you, at the least,
an idea of how to go about modifying yours.
