[TRLog] Interface cable for Knwd TS-570s

[ckuter@ix.netcom.com (ckuter@ix.netcom.com)]

I need to build a cable to sent CW only, without an amplifier.  I don't think I 
need the PTT out cable for this.  In the TR manual it says that some radio 
interfaces may require jumper for DB-9 serial:  Jumper 1 to 6 and / or Jumper 4 
to 7.  Does anyone know if the 570 needs either or both of the jumpers?

Thanks
