Was monitoring STARS 1 406.5375 freq. most of the week-end, especially with Emergency Prepardness week. Didn't hear a peep. I do know they have flown a few missions since 2010 May 1, but have not heard them. Looking at Spectrum Direct, I note that 406.5375 is no longer listed. I have heard them on 158.76 for landing at sites. I do note a few new frequencies in the 422 mHz range. Have they switched to these frequencies or have they gone to iDen? If they have gone to iDen, this will be the last year I send them a donation. Have always enjoyed listening to the medical interventions used with different medical conditons. Will be plugging in the 422 freqs. in the ole scanner to see what's up. So, can anyone confirm they have moved to 422?
