So, I was kicking about the idea of getting a signalink for PSK and stuff with the FT817. No way!
I found the "perfect" QRP PSK portable configuration:
* FT-817ND
* Yaesu CT62 CAT Cable
* Yaesu CT-39A Packet Cable
* Sabrent USB Sound Dongle
OR
* Radioshack Headphone/Mic combiner (A little dongle that splits a headphone/microphone port into headphone and mic input)
* Samsung Ativ 500t
The Ativ 500 gets about 8 hours of battery life. It's a winderz 8 tablet PC, designed for on-the-go work. It has your standard cell phone headset/mic port for audio.
Wire the packet cable with two stereo connectors (Important, especially for the microphone), and you have your soundcard interface. Add your CAT cable for rig control and PTT.
Got it all tested out at home, and next weekend I'll hit up a park or three, and try to log some contacts there :)
