+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.
