Hi Robert,
Thanks for the reply! I have been searching the web and found that the
418Mhz is used in the Radio Shack 63-1031 (temp./humidity @ $32.00),
63-1027 (temp. only @ $20.00) and 63-1037 (spa temp. @ $27.00). Many
haved used the Linx 418Mhz receivers to read and decode the payload. I
am going to purchase a couple of the products tomorrow and see who is
listed for the FCC ID number.
Thanks again,
Scott
