Top band DX-ing is real ham radio challenge. 160m is also referred as the "Gentleman's band"...
160 meters - DX-ing on the Edge...

5J0T - Bajo Nuevo and Roncador Bank

25. října 2008 v 22:47 | Petr, OK1RP |  Band reports
5J0T will be active from Bajo Nuevo and Roncador Bank
(HK0, San Andres region) between Nov 19 and Dec 02, 2008.
We will have a strong low band focus, similar to out 2007
VK9WWI operation. Operators will be HA7RY, HA8MT, HK3JJH
and AA7JV.

Plans are to operate from November 18 to 21 from Roncador Bank (IOTA NA-133), and between November 23 and December 02 from Bajo Nuevo (NA-132). Both reefs are part of San Andres region, HK0. The four person DXpedition will focus on low band operation, especially 160 meters, and will be operated by AA7JV, HA7RY, HK3JJH and HA8MT. (AA7JV and HA7RY were behind last year's VK9WWI Willis Islets operation.) The group will operate two stations from 160 to 6 m.


Bajo Nuevo is is a small reef that is part of Colombia (HK0) and is located 250 miles south of Jamaica in the central Caribbean. It is administered by the Colombian Navy. The reef contains a number of small barren sand cays, one of which carries a navigation light. The station will be setup on this cay. Antennas will be erected in the shallow water of the surrounding lagoon. (This is to save on radial wires! :-)

Roncador Bank is located 150 miles south-west of Bajo Nuevo.

The Bajo Nuevo (New Bank) is a shallow platform structure located 110 km east from Alice Shoal and 235 km southwest from Jamaica. The formation consists of two separate banks that are divided by a deep channel of 1.4 km in width. The eastern sides of both banks are marked by pronounced breaking reef crests that protect the shallow reef environments behind them. The reef was a part of the US military and was returned to Columbia in 1982.
Bajo Nuevo was re-discovered by the British Glover in 1660. Bajo Nuevo is about 26 km long and 9 km wide, covering km². The most prominent cay is Low Cay, 300 m long and 40 m wide. The reef was first shown on Dutch maps, dated to 1634, but first shown by here present name in 1654. In 1985 an American Expedition went to Bajo Nuevo in order to look for treasure ships. No more was heard about the 12 people. Till now it is unknown, if they found a treasure and went into the underground, or if they were murdered by pirates, operating in these area.
Today the cays are frequently visited by lobster fishers. A Lighttower, 69 ft high, stands on Low Cay (15N51, 78W38). Low Cay is about 5 ft high and barren. It is composited of broken coral, driftwood, and sand.

Electric power will be supplied by two generators. One will supply 120V and the other 230V for the amplifiers. 2 battery chargers and 4 batteries serve as backup.
The radios will be a Elecraft K3, an Icom IC-746PRO and a IC-706. We will have a Tokyo H.power amplifier with a homemede 2kW auto tuner and a SGC 500W amplifier with a matching auto tuner.
Antennas will be solely verticals mounted over salt water. We will bring two 18m and two 12m Spiderpoles. Six meter antenna will be DuneStar Rover 6 Quad.

5K0T QRT at 1200 Z on Dec 07.

5K0T made a total of 3000 QSO-s on TB: 2250 from Serrana

Bank and 750 form Bajo Nuevo. On Serrana Bank we had an 18

meter tall inverted L fed via an automatic antenna coupler

with 700 watts. For receiving we had a pennant, whose

direction could be switched between NE and NW (EU and

Japan). From Bajo Nuevo, we were on TB only during the

night of Dec 6 for the ARRL contest. The antenna was a 12

m (40 foot) tall inverted L. Power was 100 watts form a

K3. At both locations antennas were located over salt

water, grounded, with no radials.

From both locations we had a good mix of European, North

American, and Japanese QSO-s. There were very few SA

QSO-s.

Observations: Although on most nights we were hampered by

strong QRN from nearby thunder-storms, we could hear a lot

of DX every night between Nov 22 and Dec 06. Many European

stations were very strong and a good number had reasonable

signals. At the same time, we could hear, but not copy, an

even larger number of European stations calling who were

just at the noise level and not strong enough to make a

QSO.

On some mornings, especially the morning of Dec 1,

conditions to Japan were excellent. On Dec 1 we put a

string 100 JA QSO-s into the log in less than two hours.

Conclusions: Operating from a low noise location (other

than T-storm noise), one realizes, that when in “season”,

DX signals on TB are almost always present. It is the

level of noise that makes the difference between being

able to hear them or not.

On behalf of the 5K0T Team thanks to all for the QSO-s,

73,

George
