[TenTec] 2.031 QSK bug - this is not a bug

[Ten-Tec Inc. Amateur Radio Sales]

Ron - if the QSK loop is open, the rig does not transmit.  That's what 
the loop is used for - to inhibit the radio from transmitting to either 
allow proper sequencing of a QSK linear amplifier using a loop or to 
accept a closure from another external source to TX EN to enable 
transmit on the transceiver.  If you break the QSK loop (by pulling out 
a cable or otherwise) while the loop is enabled in the menus, the radio 
stops transmitting, yes.  This described in section (67) TX OUT / TX EN 
in the Orion II manual.  Using the same jacks as a transmit inhibitor is 
also described therein.
