[TenTec] How We Buy Things

WA3FIY> On the other had, it is quite simple to accomplish the "PTT"
controlled
function by connecting the computer CW PTT output to the
amplifier control input in parallel with T/R output of the radio.

One should measure amplifier PTT values and connect PC interface in parallel
only if PTT is within +14V/100 mA!
Some older amps like TL-922 operate antenna relays at -120V for faster
switching.

I like NQ5T thorough approach at buying the car and I wish people could buy
radios the same way.
Sometimes the whole series of excellent cars is called back to the
garrage/factory for some safety mods.
That costly operation would be required for Orion CW PTT mod but it only
applies to contesters.

Delayed RF at ARRL test report comes from semi-QSK mode allowing timely amp
relays switching.
Electronic circuit used for external controls in Orion is a nice example of
good engineering!
