TopBand is certainly open.
From E51D I worked EA8 last night shortly after my SS. Later, from about
10:00 Z most NA signals were S6 to S7, including East Coast stations. Felt
more like 80 m, but slower. Still, worked around 80 stations in 2 hours. It

I was calling CQ from 0200 to 0230, but only had one caller.
At the same time I heard OK1CF calling CQ. There seems to be a path to EU
from VP6 around that time.
I will be on 1827.5 again at 0200 to 0230 (Jun 23) and then for NA at 1000 Z

VP6A will be on TB for the for some of the time of the SP contest. Local SS
is around 0230 Z and SR is around 1500 Z. Common darkness with EU will be
very short, just after my SS. I will be listening for EU callers from .
There will be plenty of common darkness with EU and JA.

I have built, for DXpedition use, a very selective RX front-end for 160 m
for simultaneously operating CW and FT8 on shared TX and RX antennas with
800 feet of separation. The LC filter had 8 dB loss at 1825 kHz and it was
about 10 dB down from that at 1840 kHz (-8dB at 1825 and -18dB at 1840).
Hello Topbanders,
It is surprising how many ops still don't know how to call on 160 a DX form
the tropics. Many more would make it into the log, and the DX would be
making more Q-s, if callers would adjust their calling pattern to match the
RX conditions at the DX. TB is not 20. Dropping a call
TobBanders,
I will be on 1827.5 every evening at my SS from 0400 to 0430 (mainly for EU)
and then from 1000 to 1200 and again from 1545 to 1615 (my SR), until Apr 8.
(Times are +- depending on conditions.)
I normally QSY to 80 at 0430 just after EU SR. Yesterday at my SS conditions

It was noisy here earlier but by the time the band opened to ZL it got
quieter.
TKS for the call and QSO-s.

Hi Top-Banders,
FO/AA7JV will be on 160 around 1827.5 starting Mar 30, form approximately
0800 Z (local SS) every night until Apr 4.
QTH is Tikehau Atoll, in the Tuamutu Group. (Not Marquesas anymore.) I got a
good TX antenna and power but no RX antenna.

I heard OK1CF calling CQ. Karel was a real 599. He came back and gave me
599+.
Later, OM2WX called with a very solid signal. A couple of other weak EU
stations later, but I had to go on watch and could not continue.
QTH: Abut 30 miles from Cocos Island (TI9), in EJ65.

What size a rhombic would be "large" on 160 m?
Perhaps long enough for far end to be close to the other station.

In my experience, a DXpedition does not need an RX antenna on 160 for the
first two to three days. During that time they are working the big guns with
strong signals. The RX antenna is needed to give the weaker stations a
chance once the big guns are out of the way.
In case of Bouvet, most of th
ested that adding a second one made a difference. Details here:

If the antenna stands in the salt-water or if you have a short, low
impedance connection to the water, you don't need radials.
During the VK9WWI DXpedition to Willis Islets, we installed a vertical on a
sand spit that was covered by water most of the time. We had 12 radials of
various lengths a
I was operating /MM from St. Martin (FK88) and both the NA and EU stations
were weak. OK2CF, who is normally a solid S7 in FL was barely above the
noise. Conditions were either very poor or everybody was in the QRP
category. The only strong signals were form the Virgin Islands.

They have a terrific video on QRZ.
