A radio transmitter was found less than a mile away from the current polar base on Jan Mayen by soldiers, who were unloading food supplies for an upcoming 2018 scientific expedition. As far as we know, the equipment was damaged before it was buried in the snow and was not damaged by the vehicles used during unloading.
The technology used in the equipment suggest it is a 1970s radio transmitting device, not produced in Norway or similar to any used by NATO forces of that era. After 1975 murder case, there were much stricter procedures of checking what equipment is being brought by the expeditions to Jan Mayen, the 1985 eruption destroyed most of the equipment on the site, after 1985 such radio transmitter would be considered outdated due to use of vacuum tubes and not microchips.
According to documentation we were given, the 1985 eruption of Beerenberg volcano most likely moved the transmitter away from the original place of burial, which might have been close to the spot where 1973-1985 polar base was located.
In 1975, the Loran-C network of radio navigation system, part of which was installed on Jan Mayen, had intercepted a message that was sent from polar base at 2:05 AM. It was not a typical transmission for the polar base, sent on 5.9 MHz frequency, outside the usual range for communication.
Norwegian army did not reveal that fact until year 2000, when the secrecy clause was lifted for this incident. After re-opening the case we were provided access to the recording of that transmission, unfortunately it looks like it was encoded, so we have no idea what the message was.
