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)

OK – Czech Republic 60m band permits rules for 2018


Hi all,

I am happy to say that after long discussion about the technical topics and additional work on the 60m band allocation versions, requests forms and administrative details corrections I finally finished with Czech Telecommunication Office staffs the final wording of 60m band permits and rules for 2018 in Czech Republic.

Thanks to effort and willingness of the CTU staffs we agreed on the solution which allows OK hams to use new WRC-15 band allocation as same as the old experimental 12 channels used in the past!

There are two different permits available for OK hams in 2018:

1. The Worldwide Frequency Allocation of 5351.5–5366.5 kHz operation permit is sent to OK hams based on the ordinary request sent by these applicants to CTU - on a secondary basis (D.1 rule) according WRC-15 and National frequency Table approval.



C.3 rule - The maximum power in that 15kHz range is 15W e.i.r.p (see 5.133B NFT)

D.2 rule - In between 5351.5 – 5354 kHz allocation are allowed only narrow modes (CW, RTTY, PSK, etc.) with BW max. 200Hz. Voice mode is prohibited)

D.3 rule – In between 5354 – 5366 kHz allocation are allowed all modes with BW max. 2700Hz. In case of SSB the USB is preferred.

D.4 rule – In between 5366 – 5366.5 kHz allocation are allowed only narrow modes (CW, RTTY, PSK, etc.) with BW max. 20Hz. Voice mode is prohibited.

The validity of that WRC-15 permit is 5 years.


2. The experimental 12-channels operation permit is still available for 2018 and it is sent also to OK hams based on the request for an Experimental 5MHz band permission sent by these applicants to CTU. It is also given on secondary basis (ITU-R RR Article 4.4).

The maximum power on these 12-channels is remaining same 100W e.i.r.p (C.3 rule) and also other details are remaining same for 2018 as for preview year regarding the bandwidth etc.

B.2 rule – USB and CW modes allowed

B.3 rule – 3kHz channels spacing

B.4 rule – USB: 3kHz; CW: 150Hz BW

D.2 rule – Annual experimental operation report has to be sent to CTU no later then 31.10.2018

The validity of this experimental permit is 1 year.



The most important is to understand that even although the National Frequency Table with the WRC-15 allocation is approved already in OK it does NOT means that WRC-15 band allocation on 60m is opened automatically for all OK hams!

Until the new “Decree (Regulation) on the technical and operating conditions of the amateur radio communication service” – replacing the old 156/2005Sb will be done (including the WRC-15 allocation), approved and published - the WRC-15 band allocation is accessible ONLY with WRC-15 permit issued individually based on the ordinary request sent to CTU!


This WRC-15 permission is no more special just regular but until the old regulation will be replaced it is issued by CTU based on individual request only.

The OK ham applicants can requesting the WRC-15 permit or an Experimental 12-channels permit or (and it is the goal) it is possible to requesting both permits together. In case of both permits issuing the applicants are allowed to use WRC-15 together with old 12-channels allocation. Just be careful that there are different power limits and related rules.

This article is compiled based on the agreement with CTU staffs and the rules has been validated by CTU director already.
