4M1X Multi-Single Contest-expedition IARU Contest 1999

K2KW, N6TV, K6KM and YV5EED set up a station on a remote beach on the western coast of Venezuela. Operations were held at the posada (small hotel) called "Granja el Ojito"

This site was originally planned to host the larger 4M1X - M/M operation in the CQ WW contest, but the operation was later moved to Coche Island in Eastern Venezuela (4M7X). The posada used in the IARU Contest is in the middle of nowhere! The closest town of any size (above a few hundred people) is Coro, and is a 1.5 hour drive to the west.

But this posada/hotel is a real gem: it's newly constructed, and a wonderful place to relax with European style fixtures, lovely attention to detail, wonderful home cooking, Internet access, and even a few satellite channels! If you "happen to be in the area" I would highly recommend this hotel.

Multi-Single Station Equipment:

Yaesu FT-1000MP, Japan Radio Co. JST-245, (2) Fin Fett 1001 expedition amps, 2 laptops, CT 9.40. All antennas were provided by Force 12 Antennas:


4M1X - IARU Photos

Standing: Ramon, YV5EED.

Kneeling (left to right): Bill, K6KM, Ken, K2KW, Bob, N6TV. The team is holding the prototype V-3 Vertical from Force 12. The beach is wonderful, and the next houses are miles away. Though occasionally locals riding horses would pass by our antennas…

You can see the two 450 ohm ladder-lines the team used to feed the verticals. The shack is about 900' from the water, so 450 ohm line was used to reduce line-loss. Team Vertical tested the line before going to Venezuela, and found the 16 gauge stranded 450 ohm line has a loss of around 0.2 dB attenuation per 100' at 28 MHz. 9:1 transformers by Amidon were used to terminate each end of the ladder-line.

Foreground: Force 12 EF140VF/X - 40m 1/4 wave vertical using 2 elevated radials.

Background: Force 12 V-3 Tri-Band Vertical for 10, 15, and 20M

The water has strong currents so there is a lot of sediment in it (looks brown), but the water is actually very clean (and warm!).

Force 12 V-3 Vertical: This vertical is based on the driven element of the C3SS Yagi antenna by Force 12, and uses vertical dipoles on all bands. All vertical dipole elements are driven by a common feedline. The center element is the 20m element, and is linear loaded. The outer elements are for 10m and 15m and have a "hook" on each end (this is to reduce the impedance of the element to 50 ohms, as a vertical dipole is typically 90 ohms). The antenna to the right is a 15m (half wave) parasitic reflector added to the V-3 to increase gain on 15m to the north.

YV5EED operating 10m SSB. The shack was set up in a newly constructed conference room equipped with 240v AC, 110v AC, telephone lines, air conditioning, and even private bathrooms. It was a great place for the shack!

QSL 4M1X via W4SO

Direct QSL requests sent to W4SO will be forwarded (unopened) to YV5EED, QSL manager for 4M1X. W4SO is only serving as a mail-drop to ensure safe delivery.

While you send the QSL request to the USA, the return QSL will be sent from Venezuela! W4SO will hand-carry the QSLs to Venezuela, but YV5EED will handle the QSL chores in Caracas and will return them via the Venezuelan postal system.

For QSL requests sent via W4SO, include SAE + IRC/$ as you would normally send if the card was sent to directly to Venezuela - remember, the card is being sent back to you from Venezuela. (We highly discourage direct mailing to Venezuela, as the Venezuelan postal system knows about QSL cards. Letters containing IRC/$ will likely never make it to the recipient!)
