I don't know these cables but I would like to add a caution.   Some Elecraft "RS-232" interfaces are true RS-232 (voltage swings greater than +/- 8 volts) and others are TTL (voltage swings between 0 V and 5 V).   Be sure you know what you are connecting to what.   Some of the receivers are designed to accept either TTL or true RS-232 but perhaps not all of them are.  Driving true RS-232 into a TTL receiver may let the smoke out.

I'd suggest reviewing the schematics before cutting and splicing.
