The app note includes parts list with sources and a drill template. The FMA5 board is no longer available for a hand mic, but line audio from a camcorder or camera can be plugged in for sound. Dont let the SMA RF out jack scare you off, there are SMA plug to N jack adaptors to connect to your low loss coax - like LMR-400 to the antenna - or use the SMA plug to pigtail 10" long cable to connect to a TR-1b T/R relay board. Estimated total cost to package the transmitter at right is about $300 using the parts list in the application note. |
