Colombo Radio in Sri Lanka (air service) has been broadcasting on 5670 kHz in USB for some time now. Unfortunately, this information is not listed in any shortwave radio directory.

I was checking the frequency using WebSDR located in India. I didn’t see any transmission. Do they broadcast 24/7 on that frequency?
Thanks for your feedback. Radio Colombo manages air traffic in the region. This is only temporary and not a 24/7 service. I’ve been able to regularly receive Radio Colombo on 5670 kHz here in Bremen (Northern Germany) for the past few weeks.

Don’t get me wrong: Of course Colombo Radio offers 24/7 service, but unlike Air Traffic Control, they aren’t only on air when there’s air traffic.
I’ve added the frequency to the website. However, it will be automatically removed when a new EiBi update comes out. Hopefully the EiBi database maintainer adds this frequency soon.
Great, thanks so much
