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)

News from Greece on 5MHz by Manos, SV1IW

Hello Petr,

Some more news for 5MHz activity...

Following the last information on 5MHz activity from Greece we would like to spread the word. At first the beacon is ready and it has been tested forseveral days now.

Frequency is 5398.5 MHz (CW) to avoid interference with normal use of the channel mostly in the UK. It runs 30W into a non resonant antenna for the moment. You may look for it mostly between 1900-0600z. It may be off for some days due to other HF activities at the test site so try to listen regularly. The beacon is expected to run flawlessly from the beginning of 2012.

The beacon sends the following sequence at T+15 seconds (T= minute 00, 15,30, 45 every hour)

5 seconds tone on 10% of RF power ~3W
3 seconds tone on 50% of RF power ~15W
2 seconds pause
5 seconds tone on 100% of RF power ~30W
2 seconds pause
Psk31 message : "___De SZ1SV SZ1SV beacon reports sv1iw@raag.org"
Cw message : "de SZ1SV SZ1SV SK"

The beacon can be monitored with GB3RAL.zip software from Peter Martinez G3PLX. Since the software monitors 3 time slots only the first will be used(red graph)

We will accept skeds on any mode but we prefer CW. Send email for skeds and reports or more information to sv1iw@raag.org
Remember that this is the only licensed station (SZ1SV). The band is not open for other SV stations yet.
