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.

DU - DXCC #74 on 60m band CW only...


I am so happy to report over here that #74 DXCC on 60m band CW only I worked few days ago on 22/7/2017. How it was achieved? ...hard but finally done.

I tried to hear George, DU1GM for several days on 60m band and sometime I was able to copy his sigs on JT65 around 5357kHz. As I am operating CW only I asked for QSY to CW and our trials has been started.

Unfortunately propagations was against from the beginning...

When I tried to call George on desired frequency at around 19Z I was a bit surprised that he was able to hear me but it was very hard to copy my sigs and mainly I did not hear from George more that just few beeps in high noise at around S5.

Simply I had still lot of light outside so in my opinion it was too early for my QTH unfortunately.

After that I realized that I am using the short vertical towards the dipole at 20ft on the George's side. George is having also the choice of the vertical and dipole antennas but it looked like there is no gain from the vertical usage so we decided to use dipoles on both sides mainly cause of lower noise level on these antennas.

Also we had to postpone our trials a bit in order to gain more from my Sunset in QTH so we started at around 19:30Z next days.
Unfortunately the noise level on my side even using the Inverted V dipole at the center of post stamp lot garden about 10m high was still around S3... so it was nightmare to copy sigs from DU.

I decided to prepare for another day special configuration of my QTH. I switched all equipment at home OFF by main breaker and tried to listened just using the battery powered K3 and external RX loop antenna Mini-Diamond, W2PM.

Bingo, I was able to read sigs from George, DU1GM at my QTH and copy him enough for trial QSO. The problem was that propagations has changed a bit down and my sigs were copied by George really hard.

Even although George suggested to postpone all tests again for next day (he had 4:30 local time...) I tried to call him again and again.

I was really surprised when I got the call back and copied his report. I copied his 419 for me for the first time but I was not sure with that so I gave him my report and asked to repeat my RST again.

For second time I copied his 419 for me quite clear and at the peak I copied his regards as same as 73 and both call-signs at the end of our QSO. So I repeated the same from my side and his third part for me was again readable perfectly. I heard even the well known and commonly used friendly "dit dit" at the final.

My god, I worked Philippines on 60m band using my very moderate setup even although George is using just low profile dipole and WRC-15 horrible power limit...!

When we postponed the time of trials to 19:30-20:00Z we reached the SS/SR gray line phenomenon on both sides so it helped a lot I guess.

Many thanks to George, DU1GM for his effort and excellent operating skills. My DXCC #74 only CW on 60m worked...

DU - Philippines on 60m band by George, DU1GM

Hello all,

Philippines regulators have now granted access for amateurs on a secondary basis to 60m commencing July 7 2017. Band as per IARU R3 5.3515MHz to 5.3665MHz. No further information, power levels etc. Presumably as per IARU R3 15W eirp.

"I have already received some EU stations on the band in the past few months using JT65a and will be QRV on opening day here!
de George, DU1GM"

(Many thanks for good news to George, DU1GM)

Philippines nature attractions are a chief reason why tourists will fly from all over the world to this archipelagic country to see nature at its best.
In a country whose diverse beauty is a primary attraction, it becomes important to establish the type of location you would like to visit. This is because with more than seven thousand interconnected islands, it is obvious there is a wide variety of natural attractions.

Take on the volcanic mountains and go for a nature trek. Spectacular views, breath-taking scenery and simply the adventure of taking on Mother Nature. One of the most popular mountains to go trekking is Mount Pinatubo, best known for the second biggest eruption in 1991.

Another popular option for travellers wondering what to choose from in the list of Philippines nature attractions is the sheer number of gorgeous rivers. The Puerto Princesa Underground River (PPUR) in Palawan. This river is included in the list of New Seven Wonders of Nature, thanks to its intricate cave systems and length that spans 5 miles to the sea.

The number of islands is mind-boggling, but you cannot afford to tour Philippines and not experience Boracay Island. The 2.5 mile stretch of coastal strip is home to lavish establishments from where you can enjoy the natural scenery on the island.

The hilly Chocolate Ranges are also a delightful experience. The hills are one of the world’s Famous Natural Attractions, and the symmetrical cone-shaped hills that spread to the horizon make it easy to see why.
With so many islands and Philippines nature attractions, it is understandable why the country is home to numerous marine reefs. One of the most prominent reefs is Tubbataha Reef situated in the Sulu Sea. The marine sanctuary is also home to diverse bird species, so bird watchers are set to enjoy the treat of a lifetime.
