[Elecraft] SSB IMD

Which reminds me...I set my power supply to deliver 14.5V at the input to my
K3 terminals under load.  Although the power supply specification says...

"Supply Voltage/current: 13.8 V nominal during TX. (11 V min, 15 V max).
17-22 Amps typical in TX (100W). 0.9A minimum RX."

Not to hijack the review thread, but if I set my MFJ-4245MV power supply
output to no lower than 14.5V on the K3's internal meter when receiving (and
same at the output posts), under full transmit load the indicated voltage
drops on the K3's meter to 13.8V, and to 14.35 at the power supply output on
my uncalibrated DVOM. If set to 13.8V output, under full load it indicates
12.9V on the rig, and 13.65V at the power supply. Not sure where the K3
meter gets it's data.

It might be worth exploring in another thread what effect on transmitter
electrical performance there is, if any, when the power supply output is
nominally set at only 13.8V, and then drops under load almost a volt.

BTW, reviewers in the E-HAM ads are entitled to their opinions, but proper
ID adds reader confidence. The review to me reads grossly negative without
substantiation. For example, in my opinion his comments about the dual NB
efficacy are little more than a broadside rant, and display a lack of
understanding about the NB utility, if my positive experience with their use
is any indication. The rest of the review may reflect similar
unsubstantiated opinions. The K3 is not perfect, but compared with the
others that have passed through my shack, including most of the new JA DSP
radios, it's a keeper with a built-in potential for evolution.
