[TowerTalk] Wind Guages

[WA9ALS - John]

How do the Radio Shack wireless digital thermometers work, eg what freq?
Mine sits on top of the computer monitor, next to the amplifier and never
has a problem (over a year).  Lithium battery in the outside sensor still
ticking...  I was hoping the Peet Bros systems used something similar.
