 +These devices work fine using 3V3 or 5V for VCC and the digital input named
 +DATA, ADAT or ATAD works equally well at 3V3 for 3V3 VCC
 +or 5V VCC.
 +
 +To complement the FS1000A, the RF-5V (or equivalent) exists. This receiver
 +module works okay at 3V3 for short distances but is rated for 5V operation
 +which is needed for longer distances. It would appear
 +that 5V is required to operate the AGC circuit on the board. The AGC can
 +produce high levels of noise on the output when no signal is broadcast from
 +the FS1000A.
 +
 +The second photo here shows the receiver. In this setup the output is
 +fed into a cheap USB sound card whilst the FS1000A sends an AFSK signal.
 +On the receiver host minimodem is used to decode the message reliably.
