[TenTec] TT Orion: Also SEMI-BK-IN possible ?

[Bob Henderson]

Paul

I believe the key factor is this:  When you send a CW exchange the 
tranceiver doesn't know when the exchange has ended.  If you are using 
the Orion with a non QSK system or you do not wish to use QSK, then you 
have to introduce a delay period within the Orion to avoid hot switching 
etc.

This is not necessary with non Ten Tec rigs, as with direct access to 
the rigs PTT line this delay can be completely avoided.  Why?  Because 
unlike the rig, the computer knows exactly when the last character 
element of the exchange has been sent and can relinquish PTT at that 
moment.  No delay.

I am currently unaware of any other manufacturer's radios which don't 
provide an external PTT line that can be used this way, which I imagine 
is why some folks thinks its abscence on the Orion is short sighted.
