What is this? Another virtual radio using Voice IP?

Far from it!

Kelly Lindman, the founder of DxTuners has created an
artificial radio world based on the same natural laws
of shortwave radio propagation.

Skip, fading, QRM, QRN, multipath phase effects etc
are all factors and rules in this simulation. The system
follows the ionospheric laws of radio wave deflection,
but the rules can be bent - just a little.

Any operator can use this system, licensed or not.
(There is no RF emitted on a real shortwave band)

This is the perfect companion for the starving HAM
when the signals fade out on the real bands.
