[Elecraft] K3 options compatible with K4D

[Wayne Burdick]

The K4 will work with all K3 accessories:

   - MH4 microphone
   - SP3 (but we'll also be offering an SP4)
   - KPA500
   - KAT500
   - KPA1500
   - Kpod (connects to a USB port on the K4)

The K4HD uses the same style of crystal filters used in the K3, so it may be possible to reuse some of them. 

Transmit waveform monitoring is built-in for the K4 itself, and for any external amplifier that has a TX monitor output (like the KPA1500). 

Amps that don't have a TX monitor output will require an external signal tap. We may offer one, but I can't put a date on that yet.

73,
Wayne
