Rule 1 is use the minimum inductance. With an L-network there really should only be one match, or all apparent matches should be very close to the same settings. I suppose if there needs to be a rule

I can't think of a reason that they wouldn't. In fact it is even more important with a T match, since there are an infinite number of combinations that can provide a match. The point is that the wire

To my knowledge, there is no easy way to add just 60 meters to a Paragon's transmit range. It is very simple, however, to let it transmit over all of its range. There is a wire on top of the chassis

Well, I upgraded from a Corsair to a Paragon and was very happy with the A/B VFO flexibility, as well as with the great SWL and BC AM GC receive for many years (got beyond 200 DXCC) until I moved to

I use mine on 17 and 12 meters, I think 17 on the 15 meter position and 12 on the 10 meter position. I haven't tried it on 30 meters since the 3 dB advantage to 200 W doesn't seem worth the trouble,
