[Elecraft] SO2R recommendations

You can also use two separate computers for sending CW & RTTY.

For headphone and mic switching Dunestar makes a SO2R device.

You can actually get along quite well without an SO2R box.
Buying a Winkey USB would be a good start.  It gets you perfect
CW keying, regardless of CPU load; PTT; and paddle keying; all
for two radios.  The PTT works on all modes.  N1MM handles the
radio switching.

For SSB, you can use a single sound card with left channel for
left radio and right channel for right radio. N1MM handles all
the switching.

For FSK keying, there are two good ways to go, with N1MM handling
the switching:
1. MMTTY with two real com ports (you can buy a PCI or PCI-E
card)
2. 2Tone with Arduino/TinyFSK on two USB ports.  It sounds like a
big deal, but it's not really.

You will need to build a little box to handle earphone audio: LL,
LR, RR.  In LR, a pot across the two can give you a variable
blend.
