[aprssig] Wireless device frequencies

[Robert Radmore]

Recently this list has had questions regarding the transmit frequency 
of some devices. If the device has an FCC ID number information is 
usually available. Go to www.fcc.gov/oet/fccid  click on "equipment 
authorization search". Under Grantee Code enter the first 3 
characters if the FCC ID. Under product code enter the remaining 
characters. You will be amazed at the information available. Usually 
the frequency is stated, internal pictures in some cases, and 
complete schematics for many. This works for many devices we don't 
think of as transmitters.

Try it and you will be surprised.
