[CQ-Contest] Update Information Sought: "Topband Bad Frequencies" OpAid

[Jeff Maass]

Topbanders:

Seeking the collective experiences from you.

Some years ago, I assembled an OpAid for myself providing guidance in
selecting operating frequencies on 160 meters. In building it, I asked (on
this Reflector and others) for input on bad frequencies in various areas of
the World, and general band usages. Eventually, it was published online.  

It's been revised a few times with input sought again on Reflectors, the
last time three years ago. It has been suggested to me that it is time to
update this "Topband Bad Frequencies" OpAid once again.

You can review the current version at:

Please look it over, and provide me with corrections/enhancements. The "Bad
Frequencies" should be those affecting others over a large area, not your
neighborhood-generated noise. Broadcasts, beacons, birdies, and other band
noises that make a frequency difficult or impossible to use should be
included in your report. 

The band allocations notes are broadly general: there are many exceptions,
and there may have been some changes. Please provide corrections to these if
something is incorrect that might affect operating decisions on the band.

And while there is no formal "DX Window" recognized any more, I leave it
noted as many still respect the 1830-1835 range as a reserve for working
stations in other continents.

You may send your corrections/comments to me directly. I may seek
confirmations here on the Reflectors once I accumulate some changes.

Thanks!
