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.

CX - Uruguay on 60m by Ton, CX7OV



As I confirmed with Luis CX7AF, Jose CX2SA and others the 60 meters band in Uruguay "CX, CV, CW" (as opposed to our preview posts) is NOT AUTHORIZED according to official email received on 9th May of 2014 for URSEC (Uruguayan Administration).

URSEC reports that amateur radio regulation remains unalterably for today.

This segment is assigned to other services different from amateur radio.

For this reason all communications made on 60 meters band with uruguayan stations are not valid. 

Many thanks to our friends in CX for their help and co-operation and I am still keep fingers crossed into the future.

Hello, good news is coming from Ton, CX7OV. Ton informed me that 60m is new allowed band in Uruguay.

The few people are already testing the 60m band using "VICON" as CX7SI on frequency 5357.5kHz. Used power is currently 30W output on CW and its operating 24hrs daily.

I tried to copy their sigs on the band after 03:00Z  (close to SR in CX) and I detected some beeps over there but finally I am not sure if the sigs came from CX1SI. So I will try to investigate more.

Prime user activity alert in UK by RSGB

Important update: 5 MHz Band in UK by RSGB

| April 8, 2014
Users of the 5 MHz frequencies will know that this portion of spectrum is allocated (by NoV only) for amateur use on a secondary basis, available on the basis of non-interference to other services inside the UK. Ofcom have indicated that, during the coming days, there may be temporary increased usage of the band by the primary user and thus particular care should be exercised to ensure that frequencies are not in use before calling CQ.

The 320 CW Net date/time 60m schedule by Petr, OK1RP

Hi all,

I have with John, G4SRE in UK land been tweaking the freqs/times which hope it is ok for everyone for 320 CW Net activities.

The frequencies and date/time schedule proposal:

Tuesdays: 80m / 3545kHz / 19:30z
Thursdays: 60m / 5333 kHz TX and 5332kHz RX for OK land,
5333 kHz for TX/RX when only UK stations / 19:30z
Sundays: 40m / 7020kHz / 17:00z (alternatively 19:30z)

OK land does not have the same freqs which has the UKs...

Do not know what is the "320 CW Net"...?
The Clansman PRC-320 is a lightweight HF/SSB radio station designed as part of the British Army's Clansman range of radio equipments for combat use throughout the world. It was used by long-range patrols and Special Forces because of it's sky-wave range performance and hand generator system. SAS patrols in Falklands, Gulf etc. used this famous green radio and it is still working well after years.


If You are PRC-320 set owner and You would like to be in regular contact with other 320's users /CW preffered/ this 320 CW Net is determined.

Cu on the air.

GB3WES 60m beacon - off air


short info came from John, G3WGV about the off air status of GB3WES beacon on 60m band:

"The NoV for GB3WES is cancelled by Ofcom as of midnight on 31-Mar-2014 and as yet the requested renewal has not been forthcoming. I have therefore had no option but to turn the beacon off. Hopefully this is only a temporary close down." 73, John, G3WGV

I hope it will be solved quickly as it was very helpful tool for propagation check.

US Ham Ops and Government Test HF Radio Communications by Joe, W8GEX

For immediate release: 27 March 2014

US Ham Operators and Government Test HF Radio Communications
Disaster Communications Compatibility Exercise Uses Automatic Link Establishment
Washington, DC, and San Francisco, CA – 27 March 2014 - US Amateur Radio operators (ham operators) and Federal Government radio stations are engaged in a nationwide test of their capability to communicate with each other by shortwave radio, in case of an emergency or disaster. They are participating in a 12-day joint readiness exercise running from 27 March through 7 April, covering all areas of USA, using a digital High Frequency (HF) radio system known as Automatic Link Establishment (ALE). This High Frequency Interoperability Exercise 2014 (HFIE-2014) runs concurrent with the federal National Exercise Program (NEP) 2014.
ALE is a standardized digital signaling protocol used by each radio service, ham and government, to establish HF communications between their own stations. For the first time, the government regulatory agencies (FCC and NTIA) have authorized these stations to communicate with each other using ALE. HF radio enables long distance communication independent of terrestrial communications infrastructure, internet, or satellites.
To facilitate the communication testing, the Federal Emergency Management Agency (FEMA) secured temporary authority from the National Telecommunications and Information Administration (NTIA) and the Federal Communications Commission (FCC). Federal Government radio stations and hams are allowed to communicate with each other using ALE during the exercise. Under existing rules, hams have secondary access to 5 HF radio channels on which Government stations are the primary users.
HF radios used by Federal Government stations have the ALE capability built into the hardware. Amateur Radio operators have implemented the same ALE protocols using their personal computers with ham radio equipment and software. The Special Temporary Authority allows for on-the-air testing of interoperability between the hardware and software-generated ALE implementations.
Participation in the interoperability exercise is open to all ALE-capable Federal Government radio stations and to all ALE-capable US Amateur Radio stations. While five channels are available if needed, the test plan calls for using only two of the channels in order to minimize impact on other stations not participating in the exercise. 

Specifics of the STA are as follows:

(1) Temporary modification of the authority granted at NTIA Manual section 7.3.8(4), which authorizes Federal Government stations to communicate with stations in the Radio Amateur Civil Emergency Service, to allow communications with any Amateur Radio station utilizing Automatic Link Establishment, limited to the five channels in the 5 MHz band which are available to the Amateur Radio Service on a secondary basis, for the period March 27th through April 7th 2014.
(2) Concurrent waiver by the FCC of that part of FCC rule 97.111(a)(4) which limits communications with US Government stations to transmissions necessary to providing communications in RACES, limited to the five channels in the 5 MHz band which are available to the Amateur Radio Service on a secondary basis, for the period March 27th through April 7th 2014.
The HFIE-2014 is a semi-annual ham radio readiness exercise coordinated by the HFLINK organization http://hflink.com and the Global ALE High Frequency Network http://hflink.net
It is open to all ALE-capable ham radio stations. Technical and operational guidelines for ham and federal government stations are available at: http://hflink.net/hfie2014
National Exercise Program (NEP) 2014 is a complex emergency preparedness exercise with activities sponsored by government departments and agencies, designed to educate and prepare the whole community for complex, large-scale disasters and emergencies. As part of the National Preparedness Goal (NPG), it enables a collaborative, whole community approach to national preparedness that engages individuals, families, communities, the private and nonprofit sectors, faith-based organizations and all levels of government.

ICASA - extends the SARL 5 MHZ license

Update March 2014:
SARL 5 MHz Licence renewed...

ICASA has renewed the SARL 5 MHz Licence for another month pending a decision by the ICASA Council to grant a long term licence which will only expire with the start of the WRC15 in November next year.


ICASA has extended the SARL 5 MHz license till the end of February 2014.This follows SARL application for ICASA to review the license and grant facilities up to at least the start of the WRC 2015. Currently the SARL holds a pilot license for 5 250 and 5 260 kHz. While the SARL applied for extension of the license for a further period it also appealed to the Chairperson of ICASA, Dr Stephen Mnube, to consider issuing the SARL with a long term authority to use these two frequencies to continue propagation research till at least the WRX15 conference.
