"...the most comprehensive, current, and relevant online frequency database for shortwave listeners in the Oceania and South Pacific region..."
SWLD was conceived in late 1998 with the hopes of encouraging and assisting shortwave listening enthusiasts and amateur radio operators to engage with the high frequency (HF) spectrum in pursuit of the many exciting and rewarding challenges of HF communications interception.
16 years after SWLD was quietly launched
it continues to be a top 100% free service for all.
SWLD was first officially launched in January 1999 as a no-frills site (www.swld.cjb.net) and has since logged hundreds of thousands of hits from all over the globe.
Our accurate, in-depth, frequency databases continue to be referenced and replicated on countless web sites.
Notably SWLD has even been quoted in the popular U.S. hobby radio magazine, Monitoring Times.

It costs hundreds of dollars per year to host this site, so every little bit you can spare (via our PAYPAL link) will help ensure that SWLD is still here next year.
At present domain and web hosting costs are paid by the web administrators and researchers who created this site - simply for the benefit of the public (YOU!).
We hope that you may be able to donate via PayPal to help contribute to covering some of the running costs of this web resource. See bottom of page for link to PayPal Donations.
This site is not run for profit. We do not
charge for access, and we do not aim to achieve any financial gain.
In 16 years of operation we have never achieved a profit, and have never come close to completely covering our hosting costs. We only seek your help with funding to pay our government registration and web hosting fees.
16 Years of service to the radio community! What Next?
In an era where morse code is but a distant memory, and internet, satellite, and UHF communications seem to be at the forefront of every listening enthusiasts mind - the creators of SWLD believe that the robust nature of HF still provides a necessary backbone for all government and international communications.
New technologies are bringing users back every day to the HF spectrum.
Voice, data, DRM, ALE, digital encryption, and radar for military, government, scientific, commercial and amateur radio are now breathing life back into the shortwave realm.
We live in an exciting time where computers and transceivers are now working together to create a whole new dimension of HF radio. New hi-tech filtering allows the digital domain to flourish in the previously untamed realm between 3 - 30 MHz.
Computer modelling and real-time spectrum analysis now give accurate frequency mapping for reliable long distance HF commercial and military communications, providing a much cheaper alternative to renting satellite air-time.
SWLD primarily focuses on voice networks, we anticipate
that digital capable receivers (and/or digital decoding software) becoming cheaper will open up
even more interception possibilities of HF radio.
We aim to increase our HF digital databases accordingly.
All SWLD databases are compiled using old fashioned hard work - including 100's (if not 1000's) of hours of research to ensure the information presented here is correct and up-to-date.
Unlike most frequency databases we don't simply copy and paste information from other web sites or user emails.
Our Information Policy is as follows:
To deem a page, or section of a page,
current it must
be thoroughly researched and conclusively verified, without bias,
utilizing primary sources or first hand by SWLD
administrators or trusted subsidiaries with actual intercepts.
All content listed on this site not meeting this requirement has been marked as being NOT CURRENT.
Primary sources include vetted or unclassified government/military documents, or information deemed "suitable for public viewing" provided by confirmed confidential inside sources.
So, why does
SWLD include information which is considered NOT CURRENT?
Content marked NOT CURRENT is shown to assist users in monitoring radio networks.
In some cases the data presented is still actually current - but cannot be deemed verified (as per our information policy).
Such content may contain old or archival content, or may have been sourced by from a publically unavailable (confidential/restricted/secret) source or document and therefore cannot be considered as verified.
For further legal advice on
monitoring radio traffic of
the frequencies listed on this website consult your national
help maintain this resource you are invited to
We are always seeking new networks to research, donation or referral of unclassified government / official & military documents, QSL's & callsign logs, etc.
Please note that as per our information policy we will require verifiable sources.
