George is correct.

 

I worked TX5S on 80m CW roughly this time yesterday..maybe + 1.5 - 2
hours..and well before SS on Clipperton.

EY8MM was the (uFB) op.  

 

He sure wasn't vy loud, but was working them at 36-37wpm and 2-3-4 per
minute all along the East Coast of the USA and CDN Maritimes.  I don't think
I saw any RBN spots early on and pretty sure he CQ'd enough to hit some
skimmers up in New England.  My 4-sq tends to hear pretty well.  

 

As an aside, I am pleased & happy it was Nodir at the key.  I got to pay him
back for a new one I gave him (Sable @ CY0AA) in 1996.

 

Good Karma is wonderful!  I only feel sorry for all the DQRM they are
enduring.  The World has slipped in good operating practices, that's for
sure.

On RBN Sensitivity/Antennas:

Whenever I CQ-d from any of our Pacific operations -- FO/M, FO, VP6A, E51D,
KH8, KH8S -- I always had the RBN screen on. Most of the time I would be
working stations in the mid-west, or even the East Coast, before the first
RBN report would pop up, if at all. As Steve points out, they do not have
high performance RX antennas for 160 m and you can not rely on them to
indicate weak openings. Of course, if you see your call on the RBN, the band
is solidly open.

Regarding RBN . . . are there many decent 160m receiving sites in Florida .. .

There are over two dozen RBN setups west of our Mississississippi River, 
including VE; I don't rember seeing many in FL but then, I don't look for those 
when I'm watching the RBN. ZF9CW is a good, sensitive setup down in the Carib 
that I do look for, however. One of the more-sensitive out west may be W6YX, 
another VE6WX, both with at least two reporting receivers. There are several 
others at large contest stations such as ND7K who seem to report much less 
frequently. There are even several KH6 stations on the RBN. BUT...


It's just that nearly all the North American 160m RBN sites that show 
usEuropeans are mainly all in the North-east . . . yet often you will 
haveactual QSOs with stations further west.

You have to rember that MOST "serious" 160 ops are using low-noise antlers such 
as Bevs or Flags, when they give out those 559 or 579 reports to you Euros. The RBN 
stations are invariably NOT using such sensitive (and directive) antlers; so of course, 
they're only going to hear what their low elevation, RBN-receiver antlers are hearing, 
amongst their local noise. Thus, it's rare that I see a west coast station report even a 
JA, let alone 9M2AX or similar, never mind in-the-noise European. Rember: the signal must 
be a dB or more out of the noise, long enough to copy a complete callsign at least 
several times, before it will even consider reporting you.
