{K-3} K144XV

Finished install of my K144XV this AM. All works OK but, when I try to use
it with the sub receiever it is deaf. I have the sub set to Ant=Atu. Itried
using Ant=BNC but no luck here either. Sub works fine 160-6 but not 2 meter
SSB or FM.
What do I have set wrong?

Thanks Phil K8MBY

I too would be curious to know the answer to this one.

My last attempt didn't make it through, hopefully this one will.

Hi all,
As I understand it, the only input path to the K144XV is it's
dedicated "ANT 3" BNC connector, it cannot receive signals through the
ATU. The only way the sub receiver can listen to it is if it is sharing
the main receiver's antenna connection and hearing the 28MHz IF through
the KXV3A. Otherwise 2 K144XVs would be required. The sub receiver can
be set to "MAIN" to share the main receiver's signal or "AUX" which
depending on how it was hooked up when installed will either be the
non-transmitting jack on the ATU (CONFIG:KRX3 set to ANT=ATU) or the AUX
RF BNC connector on the rear panel (CONFIG:KRX3 set to ANT=BNC), neither
of which will hear the K144XV. With the sub turned on go into BSET and
tap ANT to change it's antenna to "MAIN." Holding RX ANT will also
change the sub's antenna when not in BSET. Thus, 2M diversity reception
is not possible with the K144XV. I have the sub RX but don't have the
K144XV yet (it should arrive any day), so I could be missing something,
but I have been studying the manuals in preparation. I'm sure someone
will correct me if I'm wrong. Hope that helps.

Re: {K-3} K144XV

The datasheet is quite clear - 2m reception is possible on main and
sub-receivers.

Diversity reception is not, because there's only one 2m antenna connection.

Waiting for my k144XV too !

Re: {K-3} K144XV

In reply to this post by Matt Moller

Well I have the subRX already installed and my K144XV is "out for delivery"
as we speak. I will say that I bought FM filters for both receivers cause I
wanted to be able to do full HF use on VFO A while monitoring a repeater or
scanning several on VFO B. If that's not already possible I was really led
to believe so by the documentation and some others that I spoke with on the
phone when I placed my original order. If that's not the case its not the
end of the world but id have bought the general coverage receive rather than
the second FM filter.

In reply to this post by John Lemay

Thanks to all who replied, several said 2 meter recption is not possible on
the sub.
I thought it was, Yes on both the main and sub.
When I put a 2M freq in the sub, just Ant apperas in the display, I guess it
won't work in ths Sub

Not sure why that is. Perhaps something to do with configuration -- maybe antenna configuration on the SubRX (? -- Frankly I don't even recall the various options). The K144XV appears to work here just fine on the sub-receiver. I don't have the FM filter on the SubRX, but can sort-of slope detect FM in the AM mode on the 2.8K filter, although it sounds pretty awful :-)

Why does the data sheet for the K144XV state "2-meter receive on both
main and sub receivers" and "With the sub receiver installed, you can listen
to a repeater’s input and output frequencies simultaneously."

Re: {K-3} K144XV

In reply to this post by Phillip Buckholdt-2

It sounds like the sub can be on 2m, but only if the main is as well and they are
sharing the KXV3A input path. In that case the main and sub could be on different
2m frequencies, but must both use the antenna connected to the K144XV.
Unless something hasn't been implemented yet.

Re: {K-3} K144XV

In reply to this post by Bob Cunnings NW8L

Like has been mentioned before it looks like you can only have the sub
on 2M if both RX paths are tied to the same antenna port (meaning that
the MainRX is on 2M along with the SubRX). It also states in the
datasheet that if you have the sub receiver installed that you can
tune HF-6M with the Sub wile operating on 2M with the main RX. I
really wish there was a way for me to swap that. I'd like to be able
to use my big knob to work HF and then when I'm not using the sub on
HF I could use it to monitor some of the local repeaters. At the
moment if I was wanting to monitor some local repeaters then I'd have
to use the VFO B knob to do my HF operation. Which is a bit less than
optimal. It does look like there are some extra ports on the 2M
transverter. Maybe soon we'll figure out a way to be able to use
those. I swear I remember asking someone if I could monitor repeaters
on the SubRX while using the main for HF-6M use when I was ordering
and was told that would be totally fine...

Anyway my K144XV is sitting on the porch right now. I'm still excited
to go home and get it installed! Its like most Elecraft products I've
had. Its not exactly what I want at the moment but I'll figure out a
work around for now to get close to what I want and it will probably
be perfect if I just wait a little bit longer...

Re: {K-3} K144XV

I should also state that based on my knowledge of how the radio works
and where the 2M transverter goes into the whole works I'm an idiot
for thinking that I could do what I was hoping for... Its going to
take a mod or some sort of extra nugget in or on the sub receiver to
get what I'm looking for I think...

In reply to this post by Phillip Buckholdt-2

The K3 with K144XV supports simultaneous 2m reception on Main and Sub. I just
verified it with my radio.

Set the Main rx to 2m, and then in BSET, tap ANT so MAIN appears.

Re: {K-3} K144XV

My original question was how to monitor 2M on the sub, while using the main
for HF. I don' seem to be able to do that.

No Phil. You can't do that (at this time). This will require some additional hardware (not yet available), that will allow the sub RX to have a different RF path from the transverter. Wayne alluded to this last December. It is planned, however- just not available right now. (my understanding).

Right now, you can have the main and sub on 2M (or any other transverter band), or the main on a transverter band and the sub on HF, via it's own Aux RF input BNC.

Hope this helps answer your question.
