Dual Receive on a K3?
Locked
 
|
Hey All,
I'm just getting to know my K3 (w/o sub rx) again after being inactive for a couple of years. Can anyone tell me if there is a way to have dual receive with my K3? That is, I would like the ability to hear both the tx and the rx frequencies at the same time. I know that I can op split and just use the rev control, but I'd like to hear both frequencies at the same time on CW. It could even be just using RIT/XIT rather than SPLIT, as long as I could be 2 or more KHz off the rx frequency and hear both equally. Would my only option be to add the sub-receiver or upgrade to the KX3? Tnx for any replies and, 73 W6FG |

Not possible without the sub-RX.
The KX3 does have 'dual watch' which will allow a small difference in frequency. The KRX3 can even be on different bands if you set VFO IND on. 73, Don W3FPR On 3/7/2016 4:19 PM, W6FG wrote: > Hey All, > > I'm just getting to know my K3 (w/o sub rx) again after being inactive for a > couple of years.

The KX3 has dual watch, which does many of the same things, but has certain limitations. For example, the KX3 can not use narrow band filters with dual watch because it needs to have a wide enough bandwidth to tune both frequencies at the same time. During the ARRL DX SSB contest, there were several stations that were listening in the US CW sub-band while transmitting in the SSB sub-band. KX3 dual watch is limited to 15KHz, which is not wide enough for this kind of operation. There were also DX stations doing the reverse. 73 Bill AE6JV, who finally gritted his teeth, got the sub-receiver, and is very happy he did. ----------------------------------------------------------------------- Bill Frantz | Security is like Government | Periwinkle (408)356-8506 | services.

I don't often use the Sub Rx & when I do, its usually for Diversity. Really slick integration. 73, Gary KA1J ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

You could get an LP Pan panadapter (http://www.telepostinc.com/LP-PAN.html) and this will allow you receive on a second frequency on your computer using the VFO B knob to tune (distance from VFO A determined by the sound card you use - panadapter bandwidth can be up to 192KHz). You can also listen to the VFO A frequency applying different filtering and noise reduction techniques to those set up on your K3. 73 Greg VK3VT |

This can be accomplished by any quality SDR with the appropriate software (there are multiple approaches). There are several newer SDR hardware devices that are less expensive than the LP-Pan and sound card combination that are not tied to somewhat unstable drivers. 73, ...

This is an open invitation to Joe, W4TV, to contact me. I have been unable
to get a response from you Joe, for the past 4 months, by sending direct E-mails. Please contact me. Thank you.

I have my 2nd receiver tapped and use a Funcube Pro dongle with NAP3
version 5. The main VFO I use Win4K3 with LP-PAN2 and a Steinburg UR22 USB 192Khz sound card. The funcube pro is a less expensive option for taking your IF out and getting your Panadapter working for either your main receiver or a second receiver, or both. Due to some limitations of the radio control software in the K3, you can not get the subreceiver frequency displayed correctly. What you can do is watch a second band or up/down the same band, then use A/B to send VFOB to VFOA for further inspection. I find it useful for FD to use the K3 on 6m and 2m in this manner. I also in a contest can be running on one band and then S&P with the VFOB. 73 Doug NA1DX Message: 1 Date: Tue, 8 Mar 2016 01:04:06 -0700 (MST) From: Greg VK3VT <[hidden email]> To: [hidden email] Subject: Re: [Elecraft] Dual Receive on a K3?
