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.

Nobody is perfect...


unfortunately this morning (14/3/2017) on 60m band can be called simply "foiled"...
I planned to work or at least try to work several stations this nite. Some of them were reported with good signal and some of them I heard last nites so I thought I will try to increase mu DXCC on 60m band CW only after long time a bit.

I fell asleep in the beginning of the night for catching PJ7AA from St. Maarten as same as PJ4LS from Bonaire so I missed both of them.

After I had sked with friend from KL7 on 60m but agreed frequency has been occupied with another stations (we did not set the backup frequency > my mistake) so we hade no chance for our sked this nite.

Finally I found guys from Niger, 5U5R on 5360kHz QSX 5405kHz on CW at around 05:00UTC. I though that I will try at least catching my #69 on 60m band CW only. The pile-up was not so huge and the signal from 5U5R peaked 579 so I started to call them.

Unfortunately some DF2... station has been against and call them on their 5360kHz TX frequency QZF which made a lot of QRM. Several cops tried to turn him out so QRM was even worse...

After some time 5360kHz was again clean so I tried to call them again. After about 10mins it looked promising as Dave, K3LP on key at 5U5R site got my last two letters and asked "RP?". I tried to repeat my call sign but for the first time Dave got EA9RP...asked "? AGN". So I carefully repeated my call and hoped Dave will complete my call sign finally...

At this moment some LZ2A.. operator has been against and started to call on 5405kHz into myself. His calling definitely ruined my ongoing QSO with 5U5R and we did not finished it.

I was so disappointed that I listened to 5U5R next 15mins then they appeared in noise and after they moved the band to 20m on CW I guess.

Well, what I can say... Thank you very much for QRM. I know "nobody is perfect".
Hope to work them next time.

Hong Kong is an autonomous territory, and former British colony, in southeastern China. Its vibrant, densely populated urban center is a major port and global financial hub with a skyscraper-studded skyline.

Central (the business district) features architectural landmarks like I.M. Pei’s Bank of China Tower. Hong Kong is also a major shopping destination, famed for bespoke tailors and Temple Street Night Market.

Hong Kong is located on China's south coast, 60 km (37 mi) east of Macau on the opposite side of the Pearl River Delta. It is surrounded by the South China Sea on the east, south, and west, and borders the Guangdong city of Shenzhen to the north over the Sham Chun River. The territory's 2,755 km2 (1,064 sq mi) area consists of Hong Kong Island, the Kowloon Peninsula, the New Territories, and over 200 offshore islands, of which the largest is Lantau Island. Of the total area, 1,106 km2 (427 sq mi) is land and 1,649 km2 (637 sq mi) is water. Hong Kong claims territorial waters to a distance of 3 nautical miles (5.6 km). Its land area makes Hong Kong the 167th largest inhabited territory in the world. Less than 25% of Hong Kong's land area is built-up, while the majority is grassland, woodland, shrubland, and agricultural land.

In 2014, Hong Kong was the eleventh most popular destination for international tourists among countries and territories worldwide, with a total of 27.8 million visitors contributing a total of US$38,376 million in international tourism receipts. Hong Kong is also the most popular city for tourists, nearly two times of its nearest competitor Macau.

Uruguay is a South American country known for its verdant interior and beach-lined coast.

The capital, Montevideo, revolves around Plaza Independencia, once home to a Spanish citadel. It leads to Ciudad Vieja (Old City), with art deco buildings, colonial homes and Mercado del Puerto, an old port market with many steakhouses. La Rambla, a waterfront promenade, passes fish stalls, piers and parks.

Population: 3.407 million (2013) World Bank

Currency: Uruguayan peso

The tourism industry in Uruguay is a stable component of their economy. Whether tourism contributes to the overall productivity of the economy, or provides stability by way of jobs, it is a force they have chosen to emphasize. As of 2008, 10% of the nation's jobs were based in the tourism industry. In 2007, Uruguay brought in nearly 1.8 million tourists. The bulk of the tourists in Uruguay settle themselves around the rich culture of the country as well as the scenic natural attractions. Cultural experiences in Uruguay range from interacting with the indigenous people to colonial history, as found in Colonia del Sacrementa. Montevideo, the country's capital, houses the most diverse selection of cultural activities. Historical monuments such as Tores Garcia Museum as well as Estadio sentenario, which housed the first world cup in history, are only a couple samples of the culture depth that tourists commonly seek. However simply walking the streets allows one to experience the colorful blend of culture the city has to offer.

One of the main natural attractions in Uruguay is Punta del Este. Punta del Este is a prominent tourist destination on a small peninsula off the southeast shore of Uruguay. Its beaches are divided into Mansa, or meek, (river side) and Brava, or brave, (ocean side). These beaches offer versatility to the tourist experience, the Mansa being more ideal for sunbathing, snorkeling, & other low-key recreational opportunities, and the Brava being more ideal for adventurous water sport enthusiasts. Punta del Este is virtually connected to the city of Maldonado and eastward spread widely, encompassing La Barra and José Ignacio. It has 122 hotels, 80 restaurants, an international airport and a yacht port that can accommodate 500 boats.

HAARP UAF 2.72MHz carrier, second Harmonic at 5.44MHz - Auroral doppler /fade by Laurence, KL7L


Published on Feb 26, 2017 by Laurence, KL7L

"Looking at HAARPs 23rd Feb 2017 second harmonic signal and visualizing the fade pattern and doppler/scintillation pattern. Was the Auroral style doppler naturally/solar interaction,, created by HAARPs 2.72MHz carrier or a mix? Audio on right hand channel of 2.72MHz is suppressed for easier listening."


Is there anybody else who noticed the same on the 60m band during the HAARP tests?
