May, 2006
Another winter respite to the Bahamas from the long Iowa winters is now behind us. As before, this trip was planned to coincide with the ARRL DX CW contest in which I would be a casual QRP-class entry. We stayed at the Van Gogh Bungalow from Feb 15-22, 2006, at Casuarina Point on Great Abaco Island, about 18 miles southwest of Marsh Harbor, the third largest city in the Bahamas.
TRAVEL
The Van Gogh Bungalow is a very nice fully-outfitted 2 bedroom cottage facing south and right on the beach. We spent a lot of time on the back deck and the beach enjoying the sunshine and warm temperatures (highs in the 75-85F range). Sunrises and sunsets were often spectacular. The water was about 80ft from our back door, and with our bedroom on the back of the cottage we would leave the windows open at night and hear the water lapping at the shore all night long. We bought our groceries at the three grocery stores in Marsh Harbor, and did almost all our own cooking, usually on the barbecue grill in the evenings. Our transportation was a small rental car from Sea Star Car Rentals at a very reasonable rate. Gasoline was $4.38/gallon, but we didn't use much since we only left the cottage when we needed groceries (1 trip).
Cherokee Sound at Casuarina Pt is very shallow. There are many sand bars that appear at low tide. However, it hosts an excellent saltwater flats fishery including bonefish, snapper, barracuda, and a myriad of other flats species. Offshore and reef fishing in the area is also exceptional if you hire a guide with a boat; JR provides excellent service as such. There's a lot of pressure on the bonefish fishery so they are quite hard to catch without a guide, but the numbers are significant. I spent some time nearly every day wading out and doing some fishing. I am told that the snorkeling out on the reef is very good if you're willing to make the walk out there, but I didn't do that on this trip. ![]() ![]() My current primary ham radio interest is in setting up and operating away from home in portable settings, usually during some sort of contest or operating activity. This usually involves simple antennas and QRP (5 watts or less). I believe that the Bahamas is an excellent location to operate QRP in the ARRL DX contests. It's about as close to the US that one can get and still be DX, and I generally have good results running QRP in domestic contests. Last year I took 4th place QRP in the world with only 8 hours of operation and about 430 QSO's. I believed I could do at least 2nd place this year with somewhere around 600 QSO's, so that was my target. ![]() Then I needed to determine the optimum antenna take-off angle for those areas. Some research led me to conclude that I wanted to have relatively low take-off angle antennas, though this may be somewhat contrary to general established thought. I targeted single-hop take-off angles in the 10-20 degree range for the approximately 1000 mile path to the aforementioned areas. This established an initial criteria for my antennas. Other criteria included: low-cost; easy to transport in my fishing rod case and other luggage(i.e. lightweight and small); and quick and simple installation and takedown. I had a 32ft Telepole for support. These criteria led me to select vertical antennas: vertical end-fed half-wave antennas (EFHWAs) for 40-10m; an inverted L for 80m (and 160m if I felt adventurous); and a homebrew 17ft vertical for 20-10m with a loading coil for 30/40m as backup. CONTEST OPERATION ![]() However, after the contest, on Monday and Tuesday evenings, I easily sustained pileups at 10 watts output (only 3dB or 1/2 S-unit more than my 5W during the contest) on 40m with plenty of US, VE and eastern and western European stations. So my station was working as I had expected during those times. I was also able to generate pileups on 17m during the day. I remain unable to explain what happened during the contest. Maybe propagation was just "long"? Maybe I had an inherently bad location? (I don't think this was the case.) Possibly the US/VE stations were primarily using directional antennas, pointed at Europe, which put me off the side of their pattern and therefore 15-25dB weaker? It's particularly perplexing since I not only had trouble contacting US/VE stations (which I could have explained by being QRP), but also heard far fewer stations than usual, and they were weaker. Changing take-off angle had little effect either. I really think having to compete with EU stations had something to do with it. Outside the contest my results were better, though my limited operating time only produced an additional 152 QSO's. My IC-703 transceiver performed very well, even in the contest environment. I experienced a little bit of filter blowby, but it was not a problem. The operating ergonomics of that that radio are quite good given its size. The built-in antenna tuner allows some leeway in how well the antennas are tuned, and is a real plus. Possibly the only better choice I could think of might be an Elecraft K2. I don't have one of these (yet!) to know for sure. Logging was all done with the free N1MM Contest Logging software. This works very well, but it does take some getting used to after being familiar with CT and Writelog. Radio interfacing is very simple, and I especially liked the ESM (Enter Sends Message) mode. I did have some problems occasionally while using it though, so if you heard some strange CW messages, this is why. NEXT TIME? What would I do different next time? I'm not sure what I could change to improve results at the QRP level and given the antenna transport and support constraints that I have. Maybe I'd have a 44ft doublet (5-6dB gain on 20-10m, but higher take-off angle) in an inverted vee configuration as a second antenna to the verticals. Or I would forego the 32ft Telepole entirely and just take the 17ft vertical, which telescopes down small enough to fit in my regular suitcase, thus negating the need for the fishing rod case and eliminating that extra piece of luggage. I'd probably change to RG-174 coax for this particular location, as feedline runs were short and the smaller, lighter-weight coax would be a plus for travel weight and size. It would be nice to have 20 watts or so of power that still allowed for a small power supply and battery backup if needed. I never had need to use my battery backup this time, though. I might pare down some of my backup items to reduce transportation weight and volume. CLOSING COMMENTS We really enjoy the Bahamas out islands and hope to return on at least an annual basis. They are very laid-back, and for the most part non-commercialized. The people are very friendly and welcoming, and are what I describe as "genuine"; no airs about them. English is the official language. Transportation there and back is relatively easy and inexpensive. Cost-wise for us, it's comparable to what it would cost to spend a week at a US beachfront location. It's easy to get a ham radio license. It's close to the US and has a good propagation path to Europe as well, so QRP operation with simple antennas is very feasible. The islands are fairly low-lying, so there are no mountains to deal with propagation-wise. The beaches and water are beautiful, and the fishing and snorkeling are great. Weather is usually very comfortable, although the December-February timeframe can be quite iffy since they are subject to cold fronts; weather-wise, we've been lucky in February twice and unlucky once. On the other hand, if you're the type of person that expects lots of action, nightlife, fancy restaurants, far-upscale accomodations, and many tourist activities, the out islands may not be for you; you might consider Nassau or Freeport instead. ![]() EQUIPMENT
