RF Transmitter Radio Shack

Started by Scott Lingerfelt July 19, 2005
Does anyone know what frequency or protocol "payload" used by Radio
Shack wireless products? I have tried to build the product for less but
cannot come close. I know its all volume! If I can use Radio Shack
sensors I will not need to go through FCC testing. If I know the
frequency and if I know the payload I can possibly create a repeater to
extend the distance of their sensors for my application.

Any help would be greatly appreciated!

Thanks,
Scott

Depends on the product. 418 MHz is common.
915Mhz is also used. ISM band (Industrial, Scientific,
Medical). Modulation is usually FSK, but ASK is also seen.

The emission frequency band MUST be on the transmitter
along with an FCC ID number.

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
