Welcome to Tropical band

To most people the phrase "tropical bands" bring a pretty clear picture to mind - a bunch of shirtless guys playing calypso music. But to experienced shortwave DXers those two little words express the most challenging and enjoyable part of the radio hobby. The phrase kindles memories of a DXer's best catches and favorite QSLs, of exotic stations, music and of early morning listening sessions. (Don Moore)
I like the "Tropical band" name for new 60m allocation. (OK1RP)

Effective from 1st Jan 2017 please paper QSL via OM-bureau only.

The Icom IC-735 on 60m band article revisited...

Hi all,

I decided to revisiting the old article about the 60m band modification of the Icom IC-735. Thanks to Rudi, DK7PE for letting me know about the non-functional link in that article. Also I found major mistake by copycats or even original author of the mod article on internet so I decided to completely reworking it...

9A - Croatia on 60 meters by Zeljko, 9A2EY


On the Friday, 24 th November 2017 the Croatian Regulatory Authority for Network Industries (HAKOM) published  in a Official gazette (Narodne Novine) No 116/2017  changes to the rules on amateur radio communications in the Republic of Croatia.

According to this changes  Croatian radio amateurs now have access to the  WRC-15 60m amateur secondary allocation of 5351.5 – 5366.5 kHz under ITU Footnote 5.133B - i.e. with 15W EIRP.

According to the Official gazette notice, these changes come into force 8 days following its publication, so we should expect more Croatian stations after 02.12.2017.

The changes in the rules for amateur radio in the Republic of Croatia can be found on the following web address:

I would like to express my great gratitude to HAKOM, because in the last few years they has issued a temporary one-year licenses for 60 meters to Croatian radio amateurs.

(Many thanks to Zeljko, 9A2EY for info!)

As one of Europe’s most popular beach destinations and blessed with year-round sun, Croatia’s historic towns and idyllic islands have a wealth of natural attractions to offer. From rolling vineyards to sweeping coastal cliffs, here are 10 of the most beautiful places in Croatia to add to your itinerary.

1. Dubrovnik

With its imposing sea walls overlooked by the imposing Lovrijenac fortress, mass of terracotta-colored rooftops and dramatic cliff top location, the self-proclaimed ‘Pearl of the Adriatic’ is one of Croatia’s most visited destinations. For the best views, catch the cable car to the peak of nearby Mount Srd or take a scenic walk along the City Walls, then take in the highlights of
Dubrovnik’s UNESCO-listed Old Town, known for its shimmering marble streets, grand baroque churches and magnificent 16th century Sponza Palace.

2. Plitvice Lakes National Park

A natural wilderness of azure lakes, tumbling waterfalls and forested mountains, the Plitvice Lakes National Park is one of Croatia’s most celebrated National Parks and UNESCO Natural Heritage sites. Take a hike around the 16 interconnected lakes, learn about the naturally formed travertine dams and keep your eyes peeled for brown bear and lynx prowling through the woodlands.

3. Zagorje Region

Stretching north of Zagreb to the Slovenian border, the picturesque Zagorje region is dotted with medieval castles, hilltop vineyards and thermal springs. Explore the historic town of Krapina, tour the traditional wine taverns, visit the fairy-tale Trakošćan Castle or take a hike through the scenic highlands.


Half way between Dubrovnik and Split, Makarska makes a popular stop on cruises around Croatia, with its lively beaches and colorful harbor set against the craggy peak of Mount Biokovo. It might be a quieter choice than its neighbors, but there’s still plenty to do in Makarska — make the most of the family-friendly beaches, celebrate Croatia’s swashbuckling past at the Pirate Festival in nearby Omis or hop on the ferry to Brač Island.

5. Mljet National Park

One of Croatia’s southernmost islands, Mljet Island and its eponymous National Park are well worth the journey. An expanse of greenery, punctuated by glittering saltwater lakes, dense pine forests and shaded lagoons, Mljet is a paradise for lovers of the outdoors. Once you’ve tackled the many hiking and biking trails, enjoy kayaking on the lake, discover the eerie Odysseus’s cave or go wreck diving off the coast.

6. Split

Another top attraction of the Dalmatian Coast, Croatia’s second-largest city is a major port and an important starting point for island-hopping cruises and day trips. The magnificent UNESCO-listed Diocletian’s Palace is the city’s top attraction, but there are also plenty of opportunities to enjoy
outdoor activities in Split with white water rafting, rock climbing and sailing tours all available.

7. Peljesac Peninsula

A slim headland stretching from the mainland to Korcula Island, the Pelješac peninsula is renowned as one of
Croatia’s top wine tasting regions, producing acclaimed varieties like Dingac and Postup. Once you’ve explored the region’s traditional wineries, tuck into local oysters and mussels in Mali Ston, catch some waves in the windsurfing hotspot of Viganj or scale the summit of the looming Sveti Ilija Mountain.

8. Rovinj

The star attraction of the northern Istrian peninsula,
the traditional fishing village of Rovinj entices a steady stream of travelers up the coast. Laid-back and effortlessly charming, Rovinj is a world away from the bustling resorts of the south, but that doesn’t mean you’ll get bored - discover the verdant islands of the Rovinj archipelago, hike through the woodlands of the Golden Cape or seek out a little known sunbathing spot along the coast.

9. Zagreb

The elegant Croatian capital often loses out to the coastal resorts, but the medieval alleyways and sprawling parklands of Zagreb are worth a detour inland. Check out the city’s top museums, take a stroll around the scenic Lenuci’s Horseshoe, ride the funicular up to the Old Town of Gornji Grad, or escape the capital for the lush highlands of the Zagorje region.

10. Kornati islands

The Adriatic coast is littered with islands, but for the
best scuba diving in Croatia head to the Kornati Islands National Park, a rocky archipelago of over 140 islands, where you’ll find acres of uninhabited land, colorful reefs and a kaleidoscope of tropical fish.

Miss Croatia, Barbara Filipovic

Dubrovnik’s most popular beach—which draws in so many tourists due to its proximity to the Old Town—made it onto our list thanks to its scenic views of the city’s walls, variety of water sports and beach activities, as well as the abundance of dining and drinking options. At some point, most visitors are likely to wind up at Banje Beach Restaurant, Lounge, and Club—which can get quite touristy (it even turns into a night club after dark)—but remains a consistent option for good food, tasty cocktails, and a killer view. If you’re looking for something a little more formal—or a little less crowded. head to nearby Restaurant Horizont, which turns out fresh, first-rate Croatian fare in a quaint, medieval setting.

Radio Club Argentino

Argentina is a vast country located in the southern part of South America. The eighth largest country in the world, it is the second largest country in South America after Brazil, and it's about one-third the size of the United States. Argentina is bordered by the Andes Mountains and Chile to the west.

To the east of the Andes, the interior of the country is flat, fertile grassland called the Pampas. The eastern border of the country is the Atlantic Ocean. Bolivia is to the northwest and Paraguay is to the north. The high mountain spine of the Andes, called the Andes Cordillera, creates a natural 3,195-mile (5,141.9-kilometer) border with Chile.
The country is divided into four regions: The Andes, the North, the Pampas, and Patagonia. The Pampas is the agricultural heartland.

Argentina is rich in animal species. The coast of Patagonia is home to elephant seals, fur seals, penguins, and sea lions. The waters off the Atlantic are home to sharks, orcas, dolphins, and salmon.

In the north, there are many large cat species such as the cougar, jaguar, and the ocelot. There are also crocodiles and caiman. Flamingos, toucans, turtles, and tortoises also live in the subtropical north.

Patagonia is a sparsely populated area rich in natural resources and wildlife, including herons, condors, pumas, tortoises, and guanacos.

The highest mountain in the Andes range is the Cerro Aconcagua, which peaks at 22,384 feet (6,960 meters). Northeast Argentina features rain forests and Iguazù Falls. These spectacular falls, on Argentina's border with Brazil, descend along a 1.6-mile (2.7-kilometer) front in a horseshoe shape.

Unlike Mexico and South American countries such as Peru and Ecuador, Argentina has fewer native people and a large population, which came from Europe. The population is comprised as much as 95% of people of European descent, mostly from Italy, Spain, and Germany. Much of the native population died from diseases brought in by Europeans.

Nearly half of the population lives in the area around Buenos Aires. Buenos Aires has been called the "Paris of South America," because of the European influences.

ARLB019 Communication Interoperability Training w/Amateur Radio Communicty Set

Reported by Murray K3BEQ:

ARLB019 Communications Interoperability Training with Amateur Radio Community Set

QST de W1AW 
ARRL Bulletin 19 ARLB019
From ARRL Headquarters 
Newington CT October 24, 2017
To all radio amateurs

ARLB019 Communications Interoperability Training with Amateur Radio Community Set

Elements of the US Department of Defense (DOD) will conduct a "communications interoperability" training exercise November 4-6, once again simulating a "very bad day" scenario. Amateur Radio and MARS organizations will take part.

"This exercise will begin with a national massive coronal mass ejection event which will impact the national power grid as well as all forms of traditional communication, including landline telephone, cellphone, satellite, and Internet connectivity," Army MARS Program Manager Paul English, WD8DBY, explained in an announcement.

During the exercise, a designated DOD Headquarters entity will request county-by-county status reports for the 3,143 US counties and county equivalents, in order to gain situational awareness and to determine the extent of impact of the scenario. Army and Air Force MARS organizations will work in conjunction with the Amateur Radio community, primarily on the 60-meter interoperability channels as well as on HF NVIS frequencies and local VHF and UHF, non-Internet linked Amateur Radio repeaters.

Again this year, a military station on the east coast and the Fort Huachuca, Arizona, HF station will conduct a high-power broadcast on 60-meter channel 1 (5330.5 kHz) on Saturday from 0300 to 0315 UTC.

New this year will be an informational broadcast on Sunday, on 13483.5 kHz USB from 1600 to 1615 UTC. Amateur Radio operators should monitor these broadcasts for more information about the exercise and how they can participate in this communications exercise, English said.

"We want to continue building on the outstanding cooperative working relationship with the ARRL and the Amateur Radio community," English said. "We want to expand the use of the 60-meter interop channels between the military and amateur community for emergency communications, and we hope the Amateur Radio community will give us some good feedback on the use of both the 5-MHz interop and the new 13-MHz broadcast channels as a means of information dissemination during a very bad day scenario."
