[TenTec] P.S. on A/B testing

 When I did the A/B test with a couple of rigs a few years back, I used a=

connector and then had both rigs on at the same time, on the same antenna=

felt like this was an easier way then manually switching back and forth. =
And
I felt like it was an accurate way of doing the A/B test. Of course, I've
been wrong before too. You definitly wouldn't want to key a transmitter w=

this configuration, but I felt like it was a decent way to compare receiv=

I didn't mean to poopoo A/B testing altogether. As I said, I've done =0D
probably hundreds of hours of it, listening for rx and audio qualities, =0D
MDS, ability to receive despite horrific conditions, etc.=0D

When you get to a problem is trying to copy the same station on more than=
 =0D
one radio. If you can't have both receivers listening to the same signal =
=0D
at the same time, you end up with possible variation in the signal being =
=0D
received that you simple can't control. Yes, after flipping back and =0D
forth a few dozen times, it will all even out statistically, but if the =0D
two receivers are really, really close, and you want a definitive answer =
=0D
as to which is better at hearing weak signals, a stable signal source is =
=0D
truly the way to go.=0D
