In checking on eBay, I see multiple vendors of CT-17 replacement cables with the guts built into the RS-232 connector shell. They vary in price from $19.00 + $4.00 shipping to $30.00 + $5.00. Can anyone recommend one over another or are they all essentially the same? 73, Dick -- Dick Flanagan K7VC NV SM k7vc at arrl.org
