KXPA100 Mobile Operations -- Power Output

[g8kbvdave]

Take care with inverters etc, QRM wise..

Even the "Pure Sinewave" types, employ a HF inverter internaly, and then form
the sinewave by PWM methods, much like a class D power amp.   Hence the
higher cost, as they have two types of high power switching systems in one
box.

If not well filtered, you'll still experience a lot of unwanted hash on receive.

Take care too, safety wise.  OK, you lot stateside generaly only have the QRP
110V AC types (<G>) but in the wrong place, that can still hurt, or worse.

I had very good luck with MFJ-4403 line conditioner connected to a cigarette lighter socket. 4403 has supercapacitors inside and utilizes a fact that an average current drawn by a 100W radio in transmit is usually less than 8 amp.  The conditioner is light, cheap and nondistorting. Remember to use QSK when in CW for lower average current. The average current in SSB with KXPA100 is likely to be small as the average power in KX3 is small even with the processor.
