Re: [Elecraft] K4 Vs. Flex 6400
GM Bob, A good post, which hopefully no one objects to. It does not denegrate other xcvrs and it is on topic. The numbers tell the story. Ah but some bells are nice. Must admit I use the 'DX LIST' and like it.

[Elecraft] Small keypad for KX2
Hi, I am looking for a small keypad that could be connected to the KX2 and which which I could execute commands on the KX2 like with macros on the KX2 utility program. Something like the K-Borad from www.qrpworks.com, but not a full-sized keyboard, only some 5 or 10 keys. https://www.qrpworks.com/k-board.html Does anyone know if something like this exists or could point me to a DIY project?

Re: [Elecraft] XLR on K2

Note the K2 can supply +5V on the MIC connector, while the phantom
voltage is 48V.
Phantom power ranges from about 12V to 48V, depending on the mic.
Professional mics that require phantom power are NOT compatible with the
unbalanced inputs that are used on all ham gear I'm aware of. The ONLY
way they could be used is with a dedicated phantom power supply followed
by a suitable audio transformer between the PSU and the rig.
Professional DYNAMIC mics ARE compatible with virtually all ham mic
inputs, requiring nothing more than a properly wired cable adapter. Pin
2 of the XLR goes to Mic In, Pin 3 goes to Mic Return, Pin 1 goes to the
shielding enclosure (chassis). Bias should be turned off.
Pro mics are, however, serious overkill for ham radio. "A fool and his
money . . . ." But if it's free, why not? :)
I'm speaking as a retired audio professional, ham for 66 years.
A stock K2, unfortunately, is not a great SSB rig, for several reasons.
First, the audio chain lacks enough gain to activate the limiter enough
to matter, needs low end rolloff. Second, while the RX sounds very good
on SSB at full bandwidth (where it uses the TX SSB filter), when the RX
crystal filter is re-aligned for narrower bandwidth, the response is
VERY peaky, creating so much phase distortion that it makes speech more
difficult to understand.
This is not surprising -- it started out life as a QRP CW rig, so adding
SSB was a compromise.

Re: [Elecraft] XLR on K2
If you look for a "no solder" solution, you might find XLR-to-kenwood
cables. They seem to be expensive, like

[Elecraft] K4 Notch AM doesn't work?
I just got the K4D up and running. This morning I tuned to the local AM broadcast station I listen to, which often has an annoying tone right on frequency (The K3S heard it, too). With the K3, I would just manually notch it out. With the K4, I turn on manual notch, spin the notch frequency dial, but nothing happens. From memory, the interfering tone is around 2Hz, but I can't seem to make it work on AM. Is this a feature that isn't quite working on AM as expected yet?
