K4 LF & MF, K4 EXREF?

[Elecraft mailing list]

Will the K4 transmit at 136 or 472 kHz, and if so at what power level and through which antenna port?  If so, at first ship or in the future?
The K4 brochure shows an empty hole for XREF, will this be available at first ship or in the future, and will it require an option board?  
My apologies if these questions have already been answered and I missed them.

Yes, I think all of these have been asked and answered … of course :-)

I don’t recall the specific answers to the LF transmit question.  I asked about the XREF some time ago and the answer was that it would be standard on the K4 and not an option as it was on the K3.

Yes.

Tentatively, up to ~5 dBm, using XVTR OUT only.

Probably first ship.

That makes me happy!    
I'll just quietly sit back and continue to use my KX3 until the K4 arrives.

One really cool optional setting would be a double-frequency output on LF/MF at ~ 0 dBm level.  That would allow the K4 to drive directly some of the common push-pull class D power amp designs which require, for example, 950 kHz drive for a 475 kHz output.

73, Peter.
