Multiple sensors with P3 transmit monitor

[Jobst Vandrey-2]

FYI

When I was a volunteer at the Elecraft booth in Dayton, the question of
multiple sensors was raised a number of times.  During one such discussion,
an individual from Elecraft seemed to indicate that if a switch was to be
built, each sensor in the chain needed to have continuous power.

His take was to switch the signal lines only and leave power to all sensors
at all times.  For this reason, he did not recommend a simple off the shelf
switch that transferred all 8 lines.

I'll leave it up to the experts to see if this off the cuff discussion is
still a valid concern.

Jobst,

The person who suggested the 4 port switch was none other than Alan
Bloom N1AL - who is the principle P3 designer.
If the power is a problem, I would think he would have mentioned it.
