I totally agree with this.
I've too noticed when running the XV144 at more than 10/15 W the xverter
case get pretty hot.
The Elecraft guys btw are well known to be conservative about component
choice, keeping well within the safe limits.
On the other hand, just to keep things less hot I'vee
My W6UOV (W6PO) designed 8877 two-meter amp needed more like 100 W drive to
deliver 1500 out.
In the original article, Ham Radio Magazine, Aug 1971, pp 22-28, he listed
operating parameters. He claimed 13.8 dB gain at 1 KW out. I never saw that
at 1500 W out. A good rule of thumb is gain =
What is the better solution for adding 2 meter capability to the K3, the new
internal K144XV or the XV144 transverter. I see that the power output of the
K144XV is 10 watts and that the power output of the transverter is about 20 to
25 watts. Let's assume I would want a 100 watt PA, does it
It is really up to you but a 100W VHF amplifier should not need more than 10W
of drive, typically much less. A 300W will amplifier perhaps need more
drive. Of course the output will be cleaner if under run, so a 25W amplifier
running 10W ought to be cleaner than when running 25W.
