K3 main/sub band independence -- need more firmware testers

[wayne burdick]

Hi all,

The K3's main/sub band independence functionality is working quite
well. To get it finalized, I'd like to find a few more enthusiastic
testers to pound on it. The present code (rev 2.92) is at field-test
level, so this is not for the risk-averse.

Please e-mail me directly if you're interested. I already have several
names on my list and will be contacting everyone tomorrow.

73,
Wayne

Does this allow setting VFO A and VFO B to different bands for units
without the sub-receiver?

Excellent. I bet it does not work with two transverters though - how could it? What I hope it will do is work with 6m and a transverter, for 50/70MHz crossband Es.

I can test but as I do not have the ATU the results might not be very interesting because both receivers will have to share the same antenna. Which brings me on to a question if I did have the ATU.

If the two receivers are on different bands, but with only one antenna, presumably the sub still received through the ATU which may be a problem if the ATU is lossy on that band, so... can the ATU be bypassed on receive?

Can't you use the RX in path since you have the XVRTR interface?

Yes it does...

No, not if you are using one antenna. I do not yet have an ATU, this was a general question, can you configure the K3 to bypass the internal ATU on receive. I suspect yes. You might want to do this if you were on 80m and listening for openings on 40m using a dipole for example.

You can turn it on/off on a per band basis but not on a per direction
basis.  I still think that you should be able to use the RX ant path in
some manner.  Depending on what you're trying to do.  Although I'd still
need to take a closer look at the block diagrams again but I thought the
RX path was pretty much straight in.

Depending on where the RX ANT OUT port comes from you may be able to
short the out back into the IN and then use a tap from where ever the
out comes from (hopefully before the ATU).

This has been answered several times by Wayne and Lyle.  
The ATU is in-line at all times.  "Bypassed" selects
ATU settings for a resonant (50 +/-j0) antenna.
