Don't forget like I did, make sure you give WSPR2 Admin. Rights.

Or it will load up with 30M and not the band you thought it was last on.

I love Vista, it protects my computer, but you always have to set Rights for all programs

you want to run.

Sorry for all the wrong spots today. ( a handful)

as another Amateur has suggested use just one NPN transistor if you feel happy
with a connection between your rig and computer port.

Note: the higher value resistor between RTS and base of transistor.

Just depends what transistor you have from your junk box.

I and many others believe in keeping an interface as simple as possible.

Makes things easy to repair, no RigBlasters here, or Signalinks.
