TO5RZ - St Barts. Short Expedition Report
Posted in DX by MM0NDX on April 13th, 2008
Thanks to Bob N2DVQ for leaving a comment on the original TO5RZ post. Below is his short report.

Here is a short narrative of the DXpedition. While Bob-WB2NVR and I were ready to do WPX from 6Y1V, Mike WA2VQW was sure we could pull off the effort to put FJ5 on at least 8 bands and if the sun cooperated, 9. So Mike and I designed and Mike built the 7 antennas that would need to fit in a suitcase. All the antennas were home brewed. We did not want to complicate operations by using amps, so everything was barefoot from an IC7000, IC706 and my FT-10000MP. We got everything to fit in 8 50 LB checked and 4 carry on bags. With no room to spare

We had a spare 7000 but I much prefer my MP over those little training radios.

The 160 and 80 m antennas were based on Spider beam 60′ push up masts.

For 160 we used base, linear and center loading to resonate at 1.830. Mike and I wanted to make a big effort on 160 as we both enjoy the band at home. We spent a lot of the prep time designing building and testing the 160 antenna. The antenna worked well for about 400 qso’s. I made about half of them. QRN was very bad, and QSB was like I have never heard. 599 then gone…but mostly what I heard I could work. Typically the qso’s on 160 were either 599 or 229. I know many others were calling but between QRN and QSB it was very difficult to pull anything out of the noise. Bob Wa2NVR and myself traded off on 160 as the noise was really hard on the ears. I think we made about 12 SSB qso in WPX. Mike had problems using his 706 as it would put out spurs everywhere whenever he tried 160 . The MP was Flawless.

Just a simple 1/4 wave vert on 80 with 3 radials and a little base loading with some adjustable “C”. The 60′ mast was guyed in three places (1 set across a road) to keep it up during some very fierce winds. We were about 450′ ASL so the winds were whistling through the 80 and 160 antennas for much of our stay.

On 40 Meters and 30 1/4 wave vert with 4 bent radials based on 33 foot push up masts.

0n 20 meters was a 4 el wire LPA based on the the handbook design. It was up only about 20′, supported on one end by the 80m push-up. It was pointed to EU

0n 17 we used the 80m vert and also the 30m vert with a tuner

on 15 we had a loop built on the 40m vert push up.

on 12/10 we had a vert dipole supported by the 160m mast

We were blocked to W6 for angles below about 15 degrees. The island is hilly to the extreme and we were lucky we had as much unobstructed horizin as we did. We had a clear shot over salt water to EU and pretty good path to NAE but W6 was poor. I remember the QSO with WA6MHZ on 40m. I was the last station still operting and was getting some flak to QRT but there were still QSO’s to be made, but we needed to pack tonight as we leave in the mid AM. I worked till the last possible second, got requests for more 40m for EU but sadly had to pull the plug…

It was a once in a lifetime opportunity to see what it was like to work a real pile from the DX end. My ears are still ringing…WOW

Just a note on what made it easy for me to copy a call in the pile. DON’T BUNCH UP. When someone worked me i would almost always need to move because the din that followed made on freq made it impossible for my ears to copy. Having a storng sig helps but I worked more stations that were off freq than were on. For me, a 800 hz or 200Hz note was easy to copy over the strongest sigs at 400Hz, because there were just so many. Its like trying to get the grapes back out of jelly….We all agreed that those off freq are the people easiest to copy.
