[Boatanchors] Anyone using the MFJ 1708?

[Tony Martin W4FOA]

Greetings to all:
Noticed in the 2004 MFJ catalog they are offering what they call a "RF Sense
T/R Switch", Model 1708.  Looks like it might be neat for use with a
boatanchor setup and eliminate the need to "remember" to throw a switch to
change the Dow key over from RX to TX to RX, etc.

If anyone is using one of these, I would like to hear any comments you might
have, pro or con.

TIA
