Question

[Gerald C. Lemay]

As a fellow owner of a Knight T-150A, may I take this opportunity to wish
good luck on getting that rig on the air. Be sure to rehearse your technique
of holding the VFO in one hand to adjust frequency as you transmit. Makes
the Eico 753 look good. Mine is still on the bench as I ponder how best to
resolve drift before I use it. You might be lucky and hacve one that's
fairly stable. As for the tuner, you won't need it. That PI network is
pretty forgiving and will match almost anything.

Hello All,

I have an older transmitter (Knight T-150A) that I hope to put on the air
soon.  With these older rigs is it necessary to use an antenna tuner?
According to the Knight manual the rig will match impedances ranging from
40-600 ohms. It would seem to me that one could use just about any kind of
antenna and the rig would match it with no problem without the antenna
tuner. If this is the case and I wanted to use a random wire antenna how
would I feed it? The T-150 has a regular coax connector on the back of the
rig. Should I just feed it with coax or should I still rout it through the
antenna tuner? How should I tune it for minimum SWR? Any help would be
appreciated.
