On your horizontal loop, you don't want it very high for receive only. Mine 
 is up at 15' and is incredibly quiet but no way close to my beverages. It 
is  also omni-directional and only responds to the high angle signals. It is 
no  where close when compared to a "real" beverage ! Good luck. Willy K3VW

I'd be interested to hear  the views of anyone who has experimented with a
full size (or reduced size)  horizontal loop as a 160m RX Ant. I don't have
room for long Beverages, but  have a number of "Flags" in varying formats 
and
configurations. (end-fire  etc).

I have a plot left 40m x 40m where I could add a full size  horizontal loop
as an extra RX antenna option. Of course this would work  great if I could
get it a wavelength up, but realistically I'm limited to  10m support poles
i.e. 1/16 wave length up. Although the PC advises such an  arrangement is
high angle only, I was wondering what real world experience  you guys have
using anything similar as a RX option?
It would take quite  a bit of effort to erect, (inc digging in 150m coax 
run)
so debating if it  would be worth the effort.

I am mindful the only time I could hear  YC0LOW was on a dipole at 30ft, the
1st year I came to 160m. There was no  signal on my so called "superior" low
angle RX Antenna's at the time. I had  to remove it due to RF issues as it
went too close to the TX Antenna.   How often is the high angle horizontal
RX  antenna the "winner" ...  often enough to bother..or not?

Any comment appreciated.

A day before the operation from YI9PSE ended,  I did not have any
contacts showing in the online log. During the final  upload,
four contacts for me appeared at once. One of them (80 CW) I  know
is good, and the 2nd for 80 CW might be for a busted call I  worked
earlier. There are two that I know I did NOT work, one of them
is  for 160 meters (thus, my post HERE, else I would not mention it
on this  list.)

In addition I thought I had a valid contact on 40 CW and this  did
NOT appear in the log. That was several days ago.

I think it odd  that this should happen all at once. As much as I
wish I had a good 160 Q,  the fact is, I did not. While I am near 90
worked on Topband (all with 100  watts) I am not in the range of
working something like that. Even my 80  contact did not come easily,
I caught him on a return from a quick QSY to a  dead 160.

I suppose I could send in my money via Paypal (I already did  in fact)
and wait for my unearned card to appear, but there is no way I  would
ever claim it for credit.

My question - (1) has this happened  to anyone else here, and (2) is there
someone with a call similar to mine  that is missing his 160 contact?

This is not a drill. I am  serious.

ON4UN talks about sunrise  enhancement at the location of the listener when
the listener experiences  sunrise, although I have never seen this (I am a
night owl, so I am usually  not up for sunrise).

What I have seen before and saw again tonight was  signal enhancement of the
DX station at HIS sunrise.

Happened to me  with a UA9 (could hardly believe I was hearing him), 
happened
with 4X when  I worked him in January, and it happened tonight with G3JMJ at
his  sunrise.  Lots of storm static, not much on the band, but Don was S9+  
on
my inverted L.  Tuned up the band and heard G3PQA also S9+  I  have never
heard EU stations that strong before on 160 (this is my first  season on top
band).   His signal peaked at 0550 UTC, and  gradually weakened over the 
next
30 min.  Maybe I need to re-read  ON4UN (for like the 5th time).
