What are the current frequencies for Mirs primary amateur radio equipment?
Mir has been using 145.985 Mhz. simplex for both voice and packet. This frequency has turned out to be an excellent choice which is usable by hams around the world with minimal interference to other amateur radio activities. Earlier Mir frequencies caused problems in at least some portion of the world. The previous frequency pair 145.800/145.200 Mhz. was recommened by IARU region 1 (Europe) although representatives from region 2 (Western hemisphere) expressed their reservations about the potential for interference from terrestrial sources. Those concerns were real and these frequencies were almost completely useless. Besides complaints from hams on the ground the cosmonauts aboard Mir complained about the difficulties in making good contacts. Hams in many regions had to compete with dozens of repeaters using the same output frequency as Mir’s input. Clearly the 145.800/145.200 pair was _not_ an acceptable pair of frequencies. The original 145.55 Mhz. frequency was unacceptable in Europ
