Groups

Hello everybody,

I hope this goes into the right group. I'm currently collecting information about the distribution of international vhf frequencies for wildlife tracking. It's a really challenging task as each country assigns different frequencies (some even have differences from region to region). Does somebody know if there's already a list or could post the frequencies used in their own country? 

I can start with Germany: 150.005 - 150.240 mHz

Thanks a lot!

Ah, it's 150.05 not 150.005.

In the U.S., 148-152MHz, 163-165MHz and 216-220MHz are the most commonly used for wildlife tracking.  I think there are some very specific/narrow disallowed segments in those ranges but I've generally relied on tag manufacturers to know to avoid those.   As Matthew mentioned, there are also limits on power output for legal use of these frequencies.
