Topband: B7P

Great to hear ur recording of B7P on 160m popping thru the noise, even
if I am 2500 miles further east Hi Hi.
This thread implies that Life in China comes with huge QRM-powerline
noise, which makes a lot of sense. So the Chinese ops flock to 10m.
Most of the ones I worked with my home brew Moxon at 22 ft were
peaking 59 and in some cases even stronger during a 15-30 minute
window post- Ohio sunset.

Just dabbled in the WPX contest looking for Asian stations on 10m,
and
worked a phenominal ( for me) 13 of them!
The big question is: Are there any being heard on Top Band these
days?

The last, in fact the ONLY, BY station I have ever heard (and worked)
on 160

In the past year Ive seen my 10-15-20m Chinese qso totals skyrocket
from essentially zero to 13 in last weekends WPX.
Was hoping some of those guys might discover 160, and that the good
success on 10m isnt all propagation and/or license-class related.....

Brutal QRN! Been lucky here in the country, have only had rare
occasions of heavy QRN. When I call the utility they come out within
a
few weeks and I help them track it down. Usually an arcing lightning
arrestor on top of a pole. Thats a lot of their AC going to ground so
it behooves them to clear it up.
Im a cw/ssb guy ( no digital) and it seems like most hams are now on
digital modes most if not all of the time. Considering the noise we
face on 160, I can see the attraction.

And beginning 6-8 years ago, they figured out that they had to set up
stations where the noise was low enough that they could hear stations
calling them. When they first appeared, the noise made them deaf. No
different from here in NA.

For the most part, the BYs STILL have not yet gotten to the point
where
they hear most stations calling, including JAs. Most, especially some
of
the louder big guns, are deafer than a doorknob, and it's far easier
and
more productive to call and work just about any other Asian, like a
JT,
XU, XV, 9M, etc.. I've found some of the easier-to-work BYs are the
weakest ones, perhaps because they locate away from noisy areas and
actually spend the time to LISTEN in between their CQs. A lot of the
big
guns hardly even pause between CQs, and only answer loud UA0s, who
mostly live next door.

When we tried operating in 160 meter contests from W6UE in Pasadena,
it
was amusing to see the packet spots complaining about how deaf we
were.
We were running a full size flat-top dipole at 90 feet. It apparently
worked pretty well as a transmit antenna. Using the 80 meter
inverted-vee for receive that was off the same 90 foot apex at more
or
less a right angle to the dipole actually improved things
significantly
(e.g. from really deaf to pretty deaf).
Here is an iPhone video of a Q5 "speaker copy" B7P calling CQ on 160
meters during the 2022 CQ WW SSB contest. I tried calling them (off
the
video) with no luck whatsoever. I don't think they worked any North
Americans. By contrast, during the 2024 ARRL SSB contest, JA3YBK who
was
also Q5 speaker copy came right back to me on the first call (I don't
think I have a recording of that QSO):

I just occurred to me that my description of the receive situation at
W6UE is backwards. The 160 meter flat top dipole improved the 80
meter
receive noise floor from really deaf to pretty deaf. On 160 meters we
were just really deaf whether we listened on the 160 meter dipole or
the
80 meter inverted-vee :-)

At N6RO's superstation (among other things, it was the antenna labo
of
ARRL Antenna Book Editor N6BV, who lives 100 miles away in the city
of
San Francisco), Ken patches lots of antennas to his operating
position
for 160M contests for use as RX antennas. The reason is simple -- the
elevation, and even the horizontal direction at which signals arrive
can
vary widely with time, based on propagation. Ken is a very smart
engineer, and a bunch of very smart engineers and operators are on
his team.

In the case of that 160 meter dipole it was almost always better as a
receive antenna for 80 meters. It was better at rejecting ferocious
local QRN than the 80 meter inverted-V. Absolute signal level always
dropped owing to the mismatch, but the noise level dropped even more
improving SNR (from really deaf to pretty deaf). I am sure there were
cases where the 80 meter inverted-V was better, but that was the
exception not the rule.
I agree that Ken has the nice problem of having lots of antennas to
chose from for RX :-)
