1. What about digital modes like RTTY and PSK at least? How will they display? For these modes determination of good TX quality will be huge.
The P3 screen shows the modulation envelope, so flat-topping of a PSK31 signal, for example, should be obvious. RTTY is constant-envelope modulation so you shouldn't see any amplitude changes.
2. Distance from the sensor. In the FAQ the distance supported is 5'6" but longer is hinted as being possible. What are the considerations for a longer run (say 20 feet)? For example, bigger conductors, or shielding, or...?
I'd say go ahead and try it. I haven't tested longer cables but I can't think of any reason they wouldn't work. All the input pins on the RJ-45 have pi-type R-C filter networks.
3. Switching sensors. I see that mechanical RJ45 switches are available for low prices, what are the considerations for using a switch? Also, is it strictly necessary to switch all 8 lines?
I suppose you could just leave the +5V (pin 1) and ground (pin 3) lines connected to both sensors all the time, but a mechanical LAN switch probably switches all 8 wires anyway so it's a moot point.
4. Meter display. This might be my favorite feature to have power/SWR right there at the P3, but the meter display to my eye is at least twice as tall as it needs to be. For digital contesting especially I live and die by the waterfall and hate to give up any real estate. Will the meter display height be adjustable? (I'd be happy with just the numbers down in a corner, like:
We're still tweaking the design so a shorter meter face is a possibility. You can also gain some display space by turning off the function key labels with the LABELS key or changing to a smaller type font with the "Font" menu selection.
