That would be news to me. I'm using an old Realistic Highball dynamic mic with my K3. Works just fine for me.
Wouldn't know. I have plenty of other rigs that have general coverage, I never bothered with that module.
Don't have the auto tuner. I have enough antennas that typical internal auto tuners can't handle. I also use an AL-80B on occasion, so the auto tuner would be a waste. I'm using an external manual tuner; a Palstar AT-1500DT.
Put off the sub RX unless you plan on doing a fair amount of DXpedition hunting.
The "problem" with the K3 is that you can make it what
YOU want it to be. I don't know that any two K3s are configured exactly the same from operator to operator.
If you're going to do any phone contesting, get an additional roofing filter. I would suggest the 1.8 KHz filter. If you plan on doing any digital contesting (rtty, cw, psk, etc), I would pick up a 500 Hz roofing filter eventually. I keep meaning to get another filter for digital, but even the DSP filtering seems to handle things pretty well. The DVR is also useful for contesting. I couldn't have gotten through the DE QSO Party in 2010 without one.
You're on your own on this one. I avoid AM like the plague.
