P3TXMON Advice

[Steve Witt]

I'm contemplating adding a P3 to my K3s and the P3TXMON option seems a
worthwhile addition. I am trying to figure out which directional
coupler to select but can't find much if any information between the
DCHF-200 and DCHF-2000. So I don't have any data upon which to base
the decision. At the current time I have a K3s/10 and a KXPA100 amp
and so the 200W coupler would be fine but maybe there's a higher power
amp in my future, don't know. Seems like there must be some
performance aspect that the DCHF-200 has that's superior to the
DCHF-2000 or else there would be no reason for the '200s existence.

If anyone can give a little more information I would very much
appreciate it.

73,
Steve  K6ZX

I have the 2000 Watt version and it is entirely satisfactory for me even
when operating at 100 Watts or slightly less.

Steve,

The 200 watt coupler will give more resolution at lower powers.
In other words, the 2000 watt coupler covers the scale from 0 to 2000
watts, and 100 watts is only 1/20th of the way up the scale.  With the
200 watt coupler, 100 watts is the halfway point.

I too have the 2000 watt version and I get very usable results even at QRP power levels out of the K3S.
