Let’s use MURS!

There is a band allocation available in the USA that doesn’t get the attention it deserves. I’m talking about the MURS band. Five narrowband spot frequencies around  151-154MHz (yes: VHF) where up to two watts of transmit power are allowed. For those of you brought up on 2.4GHz, that means “range” with a capital “R”. […]
