I went to tHel PNW to view this total solar eclipse. Found a place about 1
hour east of Portland, Ore a few miles south of the Columbia River Gorge with
low horizons with clear skies, a rare event. At sunrise birds started singing
and 10M opened to the east coast. As the eclipse started to
I found the discussion listed by N4HY to be an interesting read.
In 1979 thee was a total solar eclipse of the Western US which occurred
several hours after sunrise. The solar display was incredible and radio
propagation was very much so enhanced on 160 with openings to East Coast
of the US
Some headphone can isolate noise very well. I like the Sennheiser HD280 , it
provide 36db isolation, but the best one I have is the MC5 from Etymotic ear
plug that can reach 42 db isolation.

I have a pair of Sony noise cancelling phones.
Once you try NC phones, you will never go
back to conventional ones. Now if we could
just get someone to make a set with a microphone.
But you asked about CW, so that doesn't matter.
There is an issue with RF getting into them,
so they might not be
I like my QC-15 noise cancelling headphones! Worth
the money and they DO cancel-out fan noise from the
K3 and my KW amp. I don't have any clacking
relays when I key, so I can't comment on that. I use
an adapter for the 1/8" plug on the QC's.

Hi Chuck, I am using a pair of Koss KO.727s headphones. They work very nice
with my K3 and my Yaesu FT920 and FT1000. I have been using them for years and
like them very well. I see that the Koss KO.727b is listed on eBay. 73Price

Looking for tips for headphone types for K3, CW only, so need 1/4 inch
stereo jack.
Object is to isolate from ambient noise in the shack, such as relay clatter
from 1K-FA amp when keying.
Been using a cheap set that came with Yamaha keyboard - I like how they
attenuate hi freq band noise, but
Problem with the "folded umbrella" on 160 is that when the angle of
declivity is to acute serious cancellation takes place. Also the feed
of such an antenna is sometimes is very complex. I think this style of
antenna has faded from popularity since the Marconi "T" is so much
easier to
In searching the archives I see a little discussion of the folded umbrella
antenna. This looks interesting. Just thought I would see what the folks on
this list think about it
