Radio Rud - 500 kHz info

Info about our 40.673 MHz QRPPP beacon

Following contacts with our Swedish authorities about the possibility of installing a radio-beacon on a frequency segment that is exempt from the license requirement and with the positive response we received, we decided to design this 10 milliwatt small transmitter which is the maximum permitted power we can use in beacon mode.

Best 73's from the crew at SA6RR - Radio Rud.
