[Elecraft] Data mode and filters

[jim]

High end car stereo amps use DC/DC's.  Yea it's audio, but ya pay to play.
There are 300 watt DC/DC made by Vicor, Belfuse et. al.

Yea, it is more money.  But people that want to put a K3 in a mobile is out
at 4 or 5 sigma's (no data, relax, but reasonable estimate)

If ya want mobile, get the KX3.  A rig used primarily for base station
operation could be designed for better performance.  Business and marine
radios run off 12 volts and have better IMD performance, but the mfg's get
more $ for them, BUT the end sell price is not solely set by their
manufacturing and overhead costs alone.

AND having to buy equipment to support those higher voltages. Most of us
have vehicles with 13.8V systems, big deep discharge batteries are a mass
market item, and thus inexpensive.
