| + | 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. | ||
