[TenTec] 238 tuner + 600 ohm open wire

[LS Westbrook]

Anyone using the 238 tuner with 600 ohm open wire ? I
have my O1 w/tuner,  238 to 600 ohm,  readings on the
tuner are erratic to say the least.  I can get the swr
reading on the O1 to a decent level but I'm afraid
that is just the match between the rig and the tuner ?
 I do have the rig connected to ant #4 on the tuner.
Any tips would be appreciated.
