OIRT

From HFUnderground

In Soviet Russia, radio listens to you!

OIRT FM broadcast band, 65.8 MHz to 74.0 MHz. 10 kHz offset channels. Lower frequency means longer range but much higher susceptibility to sporadic-E or other skip propagation. 50-75 kHz wide FM WFM W-FM. Operates in the 66-88 MHz VHF mid band region and can cause major interference to the 70 MHz amateur band / 4 meter band / 4m band and/or land mobile services operating in the 66-88 MHz band. This includes the license-free 69 MHz and RHA68 services in the Nordic countries.

Russia and former Soviet republics, Baltic states, Eastern Europe. Slowly being phased out in favor of the 88-108 MHz FM band. Still used in Russia and other countries for FM broadcasting (in addition to the now-standardized "Western" FM band).
