FT report on K3 subreceiver

[adamkern]

Are there any field tester reports on subreceiver function and
integration?

The KRX3 has not been released from engineering.  No one has it yet.

Nope - becauses there aren't any out there yet.  However, it is exactly the
same hardware as the main receiver and you have the same control over it as
you do the main one - so it should work exactly as well.

I apologize if this has already been discussed or already posted on
the Elecraft site, but:

If I combine a K3 with an XV144 transverter:

- would I be able to use main and sub bands to simultaneously listen
to, for example, 40 meter CW and 2 meter FM -- controlling each
signal's volume independently through the same speaker?

- what 2 meter receive frequency coverage would this allow?  I'd like
to be able to receive up to 154 MHz or so.

Please reply off list.

Thanks,
--Andrew

That raises an interesting point, not that I think I'd need to do this in
current conditions, but a K3, KXV3 and a XV144 would only allow you to Rx/TX
on one 2M freq at any one time - so it would effectively take another KXV3
and a XV144 to be able to receive 2M via 2nd Rx in K3 - something that
probably isn't going to be easy to do - probably easier to buy another K3 as
well.

Actually, I suspect it is possible to configure things so that you can
*receive* on two different 2m frequencies if using a K3 equipped with
Aux receiver.

Yes. There are two ways to do this.

1. The main and sub can share the received signal coming from the XVTR
IN jack, via the passive 3-dB splitter.

2. The sub receiver's aux RF input can be routed to the "AUX RF" BNC
jack near the main antenna jacks. This jack could be connected to RX
I.F. output of a second transverter. This would eliminate the splitter,
although in practice, the NF of the system is established at the input
to the transverter, not its I.F. But it would allow you to get the main
and sub RX inputs from separate transverters if required. You could
even use different I.F.s. The K3 allows you to set up each transverter
band independently (up to 9 bands), and put the two receivers on
different bands.

That is just Fantastic and I have all components on order - is the 3-dB
splitter included in K3/100 or KXV3?
If not, I'll have to order one, but don't remember seeing that as an option

It is an integral part of the KRX3.

The passive 3-dB splitter is only needed with the subreceiver, and is a
part of that assembly.
