Welcome to the PA0RCT cw station

The main trx, an OMNI VI (plus) is located in the center, keyboard and bencher paddles situated for maximum comfort. When not in a contest, the keyboard can be pushed back under the trx. The memory keyer (most important piece of equipment in the shack) is located on the left side, to enable two-handed use. On top of the OMNI sits the Timewave 59+ DSP unit. Although the DSP of the omni is quite effective for CW (it does not decrease the "crud" but enhances the signal, making it really stand out) I like using both at the same time. The T59+ bandwidth is normally set at 500 Hz, noise reduction on. The auxiliary antenna on the OMNI is an EWE, pointing NW. This antenna reduces the noise we have on the mains from the big phase-controlled fans of a chicken farm near-by. The EWE is optimized for 80 meters, but works on all bands with null directions varying per band. (On 20 the null direction is stateside....)

To the left of the main TRX is a FT757 used as a second TRX. On top of this a tuner for the 2nd antenna (a low windom for 40-10).

The computer monitor is at the far left.

The amplifier is at the right. In the Netherlands only 400 W output is allowed. The tuner is only used for the 4x20m loop skywire. The loop can be used at all bands. A 160m inverted L, the 40m vertical and the 20m dipole are properly matched. 15m is handled via the 40m vertical. The antennas are switched manually with a 4-position coax switch.

The thing to the right of the TRX is a clock synched with a caesium standard, allowing the contest to start exactly on the second!

The PSION organizer is used for logging outside the contest. (If you have one, don't forget to visit the PSION HAM SOFT PAGE.

7 MHz full size vertical hidden in the woods
On 40m I am using a full size vertical with 24 radials of 5m long. There are plans to add a few guy wire reflectors to get some directivity into the main directions(US, JA, S.E. ASIA).

The base of the vertical is fitted to a wooden pole

Feedpoint of the loop skywire

The insulators for the several wires normally serve an electric fence

The radial of the 160 meter inverted L is tied to the tree with a "bowline knot".

All other antennas are wires:
  • A 4x40 meters loop sky wire, 12 meters high. Going extremely well on 80 meters, also useable as a cloud burner on 160. On the higher bands radiation is at low angles (works as some sort of rhombic). As the feedpoint is now over 50 meters from the remote antenna switch, I use open line and a 4:1 transformer.
  • 160 meters: inverted L with 1 radial pointing West. Parallel to this there is also a wire for 80 meters, but the loop skywire is much better, also for DX.
  • For 15 meters both the loop skywire and the 40 meter vertical can be used.
  • For 10 meters the loop skywire works great. No directivity, good for the contest..
  • There are no triband beams, full size verticals for 160 and 80, etc., but the station is coming out loud enough to have fun in the contests... and that's what it's all about...
