I need to output the 5khz, not input it. Would I be able to do that with a sound card in a small form factor? The idea is to have a small box that can convert my heart rate monitor to something that the gym equipment can understand.
- ronsor 5y agoI believe attaching an antenna to the card's output could work. For small form factor, a USB sound card and a Raspberry Pi is a possibility.
- jpindar 5y agoI've used a cell phone as an audio signal generator for testing transmitters. There are apps for sending a continuous signal, and I assume it would be easy enough to write one for sending a modulated signal. BTW, this is one reason why I won't buy a phone without an audio jack.
