Re: K3 question re dual receive

[Fred (FL)]

Could someone explain, what "Dual Receive" is
supposed to offer the K3?

Can I transmit on 1 band, and simultaneously
RECEIVE on a different frequency?  Can I
listen to 20m SSB and low 20m CW at the
same time?  With 1 antenna?

What does the K3 say, that we can do with
this DUAL RECEIVE capability?

Fred, N3CSY

Monitor two bands simultaneously with some top-notch digital mode software.
Great for watching 10m and 6m when otherwise a tad dead.

See the K3 FAQ on the Elecraft web site.

No.  This is duplex operation, not dual receive.  The K3 is not designed for
duplex, which would require incredible RX shielding.

Yes.

Yes, and also with two antennas, one for each receiver, your choice.

Receive on two different frequencies at once, with one in each ear of the
headphones, or mixed.  The two frequencies can be on different bands and
different modes.

This may be possible at low power, with certain band combinations, but
we haven't tested it yet. Certainly not at 100 W. As Ed implied, it
would require complete physical separation of the two receivers,
greatly increasing cost, weight, and size of the rig.
