Re: [Elecraft] Linked VFO's -- usage?
Thanks for your support Guy. I have addressed this subject several times in the past (with no success). I often use diversity in contests (ever since I have my K3, which carries #1255). Now that the K3 runs the diversity form one VFO and the problem of the filter offsets seems to be solved, this is the last thing to improve. 73 Arie PA3A Guy Olinger K2AV schreef op 3-8-2015 om 23:29: The counter to yet another mechanical outside box is that the ability to write firmware and update it inserts another very major possibility, that it can be done in the digital stream without need of extra cords and boxes.

Re: [Elecraft] Linked VFO's -- usage?
Don, I know what diversity is Don, and I use it as you describe. It just happens that I sometimes need to concentrate on one channel only to make the QSO. That's where the A-A en b-b come into play.

Re: [Elecraft] Linked VFO's -- usage?

Since you can't do it with the current K3 software, where is the A/B testing shows the superiority of listening to separate signals in each ear. I suppose there are papers out there on this.

Re: [Elecraft] Linked VFO's -- usage?
Don, and all: I don't think diversity will work with different VFO's. Both Rx need to be in phase from one LO for diversity reception to work. I run diversity Rx on 2m with RF channels that are orthogonally different polarity and that feeds dual IQ baseband thru a four port soundcard to my computer running a special form of JT65 which can pick out the angle of polarization from the two signals and peaks reception. Every part of the RF chain needs to be in the same phase for that to work. The K3 + KRX3 was the only ham radio to offer this for my IF. I use two LP-Pan on the 1st IF of the K3 and KRX3 to get that. Details are on my website under Tech Topics/SDR/using MAP65... I have not used linked Rx but can see its value keeping one VFO a fixed offset in frequency from the other as one tunes. I have used a somewhat similar idea with a VHF/UHF satellite Rx/Tx where the Tx keeps a freq relationship with the Rx frequency. It was not a simple linking because the system had to adapt to different Doppler effects. I will attempt to link my K3 + 432 transverter in Tx with my KX3-2M for satellite operation. But tuning of both will require special sw to take care of the changing differential in offset. I do use Tx split freq when operating 1296-eme because Doppler can lead to offsets as high as 2-KHz between stations. But that is the normal Rx-VFOA, Tx-VFOB, and not using linking of the dual Rx. EME at 1296 and higher uses circular polarization that overcomes polarity mismatching so my dual-pol diversity Rx is not needed. I have not upgraded my K3 firmware to the vers that has separated linking and diversity on the SUB button. 73, Ed - KL7UW From: Don Wilhelm w3...@embarqmail.com To: Arie Kleingeld PA3A p...@xs4all.nl, elecraft@mailman.qth.net elecraft@mailman.qth.net Subject: Re: [Elecraft] Linked VFO's -- usage?

What I do is switch antenna connections. My secondary antenna is connected to both the RX ANT and the sub's BNC input. So I can listen to the main + secondary antennas in diversity mode, just the main antenna with diversity off, or just the secondary antenna (regardless of whether diversity is on or off) with the RX ANT switch on. 73, Vic, 4X6GP/K2VCO Rehovot, Israel http://www.qsl.net/k2vco/ On 2 Aug 2015 17:34, Arie Kleingeld PA3A wrote: Hi all, I might be one of few people who use the Linked VFO's in diversity, not that I want to, but because I have to.

Re: [Elecraft] Linked VFO's -- usage?
Arie, When in diversity, normally both the SubRX and the Main RX are controlled by VFO A. You must be in SPLIT to do what you are doing. Is that true? 73, Don W3FPR On 8/2/2015 10:34 AM, Arie Kleingeld PA3A wrote: Hi all, I might be one of few people who use the Linked VFO's in diversity, not that I want to, but because I have to.

Arie, Haven't drawn this out, but couldn't you accomplish your headphone audio routing requirement via a simple outboard switch or pair of switches mounted in a small box? 73, Dale WA8SRA Hi all, I might be one of few people who use the Linked VFO's in diversity, not that I want to, but because I have to.

From: Cady, Fred fc...@ece.montana.edu Date: Sat, August 01, 2015 4:05 pm To: elecraft@mailman.qth.net elecraft@mailman.qth.net Hi All, In the current K3 firmware (going back a few versions) you can link VFO A and B with the CONFIG:VFO LNK menu. You used to get them linked by holding SUB, but now that turns on diversity. A good change. Linked VFOs is not diversity, in which VFO A controls the main and sub receivers independently of VFO B. In linked mode the two receivers remain independently controlled by their own VFOs but when you tune VFO A, VFO B tracks along. Tuning VFO B doesn't change VFO A. So, I'm wondering what others are using linked VFOs for?

Re: [Elecraft] Linked VFO's -- usage?
Fred, I was mortified when first suggestions appeared saying the linked feature should disappear and I became a vocal critic of removal and hear is why. I don't have or intend to add the second receiver and I think I am not alone. I chase dx most of my operating time and Dxpeditions are high on my list. As we all know these ops often run up 2 on cw or up 5 on SSB with variations of their split. Setting the vfo's to 'linked' I run up and down the band I am on and when I find the station I am chasing I have the k3 set to split and I can quickly jump in and get the contact. This style has kept me away from the 'up up up' cops and keeps my blood pressure in normal range. Always a good thing right? Are there other uses? Maybe, maybe not, but this works nice for me and I have operated this way for thousands of QSO's since '08 with #679 Hope I explained this correctly as my k3 is at Elecraft for upgrade and repair and waiting for the billing department to issue an invoice do it can be shipped back. Don't ask me why it takes days to get an invoice, I am not impressed.

Re: [Elecraft] Linked VFO's -- usage?
Hi Dave, You don't need to use linked VFOs for this purpose. If you've set up a repeater offset on the current band, and have selected +/- rather than simplex (using the ALT switch in FM mode), then transmit will automatically be offset that amount from VFO A no matter where you tune in the band. For this reason, you don't need to use VFO B at all when using FM and repeaters with the K3, K3S, or KX3. Hence no need to use VFO linking, SPLIT mode, etc. 73, Wayne N6KR On Aug 1, 2015, at 1:58 PM, Dave New, N8SBE n8...@arrl.net wrote: Operating split on 10M on the FM repeaters.
