Cool Radio in the Hot Tropics – St. Kitts & Nevis October 2024

Many thanks to Bob K4RLC who shares this report on mixing vacation with ham radio with us.  If you have an article in your head and want to have it posted here, let’s keep this community going while our friend Thomas continues to help his neighbours in the wake of Hurricane Helene in Western North Carolina. Draft up your story in an email with reference points to the pictures you want embedded and their captions, attach photos to the note and send it my way to vincedeon at gmail dot com and note QRPer in the subject line to get my attention.

Our interest in a trip to Saint Kitts began pre COVID, after my buddy Dale W4AUV and I saw an ad in the back of QST magazine by W5JON, John, for his rental villa with a complete ham radio station on this Caribbean island. What could be wrong with this scenario? Being on a beautiful Caribbean island with a complete ham radio station?

Fast forward almost five years later, when Dale and I, along with our spouses, leave Raleigh for St. Kitts.  The timing was really bad for me, as at the same time Western North Carolina was devastated from Hurricane Helene. In the past, I worked with the American Red Cross Disaster Services after hurricanes and tornadoes in my home state, as well as being deployed to the Gulf Coast of Mississippi and Louisiana immediately after Hurricane Katrina. We have friends and family who live in upstate South Carolina and Western North Carolina Including my best friend from high school and his family. All we could do was reach out to them with support, and donate money through reputable organizations such as Samaritan’s Purse Disaster Relief and the American Red Cross.

St. Kitts only has three POTA sites and no SOTA sites.  I had hoped to activate at least two of the POTA sites. CW is my preferred modality. These POTA sites had only been activated by phone and dubious digital.

Saint Kitts is an unquestionably beautiful tropical island, but it is still a third world nation. The driving is British style, further complicated by having only three stoplights on the island and roundabouts every few miles. We rented a Honda CRV from Bullseye Rentals, recommended by John W5JON, the owner of the villa. Given the ancient small roads where everybody drives like your drunken old aunt with dementia, this was a good vehicle choice. Since my first and primary activation was to be  Brimstone Hill Fortress National Park, a UNESCO site built starting in 1690 with guarded entryways made to fit horse drawn wagons in the 1700’s, we were relieved to have passed up the large Ford Explorer rental in favor of our little Honda SUV that barely made the entryway.

Brimstone Hill Fortress, also known as the Gibraltar of the Caribbean, is an expansive stone fort originally built by the British in 1690 with African slaves. It has been through many modifications over the years, and different owners, but is essentially British. In fact, its construction reminded me of Edinburgh Castle in Scotland.  (I was later told that Brimstone was designed and built by the Royal Engineers from the UK). Now, it is a National Park, a POTA site (KN-0003), and a UNESCO World Heritage Site.

Proper QRO: K4RLC Tours The Edward R. Murrow Transmitting Station

Many thank to Bob (K4RLC) who shares the following guest post:


Visiting VOA Site B: The Edward R. Murrow Transmitting Station

by Bob (K4RLC)

Two week sago, Dale (W4AUV) and I were treated to a “under the hood” visit to the last remaining Voice of America transmitting station in the United States. It is located in eastern North Carolina, and officially known as the “Edward R. Murrow Transmitting Station” part of the “Office of Cuba Broadcasting” in Grimesland, North Carolina. Also, known as “VOA Site B.” This type of shortwave broadcast station is only one of a few remaining worldwide.

This VOA site has been on the air continuously (24/7/365)  since the 1963 on-site dedication by President John Kennedy, broadcasting up 8 transmitters at a time on the short wave bands. There are three 250,000 watt and five 500,000 watt GE, Continental and Telefunken  transmitters feeding 38 possible antenna configurations, with an Effective Radiated Power of 2,000,000 watts. (There is also a 39th antenna, that is a Dummy Load that will handle 500,000 watts).

The antenna field covers over 6,000 acres of flat, costal plain wetlands, not far from the  Atlantic Ocean, so it has a minimal absorption factor and a salt water boost.

TCI “Curtain” antenna made of 4 dipoles wide & 6 dipoles high, pointed at Cuba. It is controllable in both vertical and horizontal azimuth, depending on the configuration has to up 23dB gain at a 4 degree take off angle

The antennas are fed by over 26 miles of 300 Ohm open line “ladder line” with a minimal SWR and minimal signal loss. The largest antennas are called “Curtain” antennas, given their configuration, of matched horizonal and vertical dipoles suspended between large towers, giving the visual impression of huge curtains.

There are also  rhombics, each 6 wave lengths long. The rhombics are not used as often, given their narrow bandwidth and narrow beamwidth. The Curtains can bathe a large geographic area (such as part of a continent) with a very strong signal. The primary broadcast areas for this station are Cuba, Central and South America, and Africa (although the antennas could reach out and touch Russia and eastern Europe, when needed).

Many of the engineers are hams, including Macon (WB4PMQ), the chief engineer. Gary (N2AD) transferred to Greenville when the VOA in Bethany, Ohio closed. (The Bethany VOA site operated during WW2 into Germany, and was referred as the “Ohio Liars” by Hilter !)

Glenn (W7GSW), a US Navy communications vet, has been at the site many years and conducted much of the tour for Dale and I. Continue reading Proper QRO: K4RLC Tours The Edward R. Murrow Transmitting Station
