VFO indepence

Hi, I'm not able to force CONFIG:VFO IND to yes. When I try, the LCD shows: NO SUB, the KRX3 is working fine.... It's supposed to be possible to set the sub receiver to a different band from the main this way, but I can't get it to work. Any ideas? vy 73 Eric PA3CEV K2 960 K3 122 _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

This feature is not yet implemented, please check the release notes and errata. 73, Lyle KK7P _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

This is the most frustrating issue I have experienced with the K3. I
really enjoy the rig, and this is the only nit I have experienced. I would like to be able to (during contests) pop over to other bands, listen for a moment and pop back. But this is not available at this time. The release notes mention the following: TUNING EITHER VFO ACROSS MULTIPLE BANDS now brings the other VFO along with it, so that both VFOs will always be on the same band. This eliminates the problem of bands getting out of sequence due to wide tuning excursions. (Later, we’ll allow the subreceiver to be on a different band from main if CONFIG:VFO IND is enabled.) Tech support has indicated that this _may_ be something that is addressed in a future firmware release. Time will tell. For now, I am going to try and get a second antenna setup, and get the K2 back online. Then I can use it as a second receiver. My frustration was really notched up when I was able to split the VFO's on a 706MIIG in the vehicle, but cannot do it on the K3. For now, I continue to enjoy the awesome radio, and wait to see what happens. David Wilburn K4DGW Eric wrote: > > > Hi, > > > I'm not able to force CONFIG:VFO IND to yes.

K3's 2nd receiver on different band?

In reply to this post by KK7P
I may have stumbled onto an uh-oh ... for me anyway.
I was about to order a 2nd receiver for the sole purpose of monitoring a -different- band (6M) while using the K3 on a different band/mode. Can I do this? I was under the impression that one can do this, but recent postings about VFO's make me think I was incorrect .... Perhaps I'm reading something incorrectly. 73!

Hi Ken,
We fully intend to do this. Its a small matter of programming (SMOP). :-) In this case its a fair amount of work to enable this, but it is high up on our priority list. 73, Eric _..._ -----Original Message----- From: "Ken Kopp" <[hidden email]> Date: Saturday, Aug 9, 2008 10:07 pm Subject: [Elecraft] K3's 2nd receiver on different band?

Ken I think you will find the 2nd receiver picks up it's signal via the
ATU and TX low pass filter, not having one I could only try working it out via the schematics... I have an external antenna splitter that could be used with a 6m pre-amp to feed a 2nd receiver, although again the ATU/LPF may be an issue depending on band combination. If you have the KXV3 you might want to try it and see if it works for what you need - it's a bit cheaper than a KRX3. I have a couple of "needs" with my K3, (1) to improve the RX on 6m and (2) to run dual receive. The receiver performance is worse on 6m than my TS-480 by about 8 dBm and I sometimes struggle hearing weak signals on that. I bought an Advanced Receiver Research pre-amp type P50VDG (http://www.advancedreceiver.com/) and connect it between RX OUT and RX IN on the KXV3. It has quite a lot of gain but I didn't find it needed a 10 dB fixed attenuator on the output, the K3 ATT works well enough. Being very low noise there isn't a high level of hash from it and it can be switched out of circuit easily by pressing the RX ANT button on the K3. The MDS in a 400 Hz bandwidth increased from -136 dBm to -146 dBm with the external pre-amp. Regarding splitting the receiver signal to feed another receiver, in my case my K2 via it's RX only antenna input (part of the K160M add-on for the K2), an external ferrite splitter works well. It has 3 dB loss and around 20 - 30 dB isolation between output ports. Wire the splitter input from the KXV3 RF OUT, one output from the splitter goes to KXV3 RF IN, the other to the K2 RX antenna socket. The K2 can be muted by putting it to "TEST", turning the power to minimum, sidetone to zero and t-r time of around 100 mS. Wire the KEY OUT from the K3 to the KEY IN of the K2 and now you have a 2nd receiver. The external receiver can be quietened by pressing the RX ANT button on the K3, in case of needing additional sensitivity on the K3 the RX ANT button can be used to bypass the splitter and remove the 3dB loss. Winding details of the ferrite splitter are on my K3 page at: http://www.astromag.co.uk/k3/ My K3/K2 combination is mostly used on 80m with the K2 monitoring the CW QRP frequency of 3560 and the K3 elsewhere on the same band. 73 Dave, G4AON K3/100 #80, K2 #1892 -------------------------------- I may have stumbled onto an uh-oh ... for me anyway.

Using the AUX input for the sub receiver would work around all that.
