Hello All. I have a Kenwood TS-570S/G HF Transceiver and i would like to connect it to the sound card IN/OUT jacks of my computer for use with SSTV. Can this be done direct (as with the TS-440) or will i need an interface? I know how i can connect them together direct but would it cause any harm to either machine?? Thanks for any help. -- VE1KRE...Keith.
