[Elecraft] [P3] P3TXMon Wattage/SWR

[Alan]

The currently-shipping sensors are the same for the W2 and P3 TXMON.  If 
you have an older W2 sensor (I'm not sure of the S/N cutoff date), it 
will work, but the bandwidth may be limited on the waveform display.  It 
can be modified by changing several capacitors.  I don't see 
modification instructions on the web site but I think Elecraft Support 
should have the details.

One sensor cannot drive both devices. You would need a 8P8C (RJ-45) 
mechanical switch for that.  You could also use such a switch to select 
one of several sensors for the P3.  This is the one I bought, but there 
are others:
