Initial draft of the hardware requirements.

| 3 | There are a number of alternatives for hardware to capture a P25 baseband signal. These include: |
||
| 4 | |||
| 5 | * USRP (using TVRX daughterboard and appropriate antenna). |
||
| 6 | * Custom interface to existing scanner using soundcard for quadrature sampling. |
||
| 7 | * Custom PSK to serial interface hardware. |
||
| 8 | |||
| 9 | Initial work is proceeding using the USRP because it is capable of wideband reception and requires no special-purpose hardware. A USRP with the TVRX daughterboard and an appropriate antenna is all that is required and is capable of much more than just intercepting P25. For those without any hardware it is possible to investigate using some signal samples which are available on the DemodulatorPage. |
