Re: [Elecraft] K3 Diversity RX question
Jim, With BOTH 'Split' and 'Diversity' engaged, you will only be able to listen to VFO-A, although VBO-B WILL be your transmit frequency. In other words, you will be listening to the DX on VFO-A with full benefits of Diversity. However, you can press and hold the "REV" button on the K3 which will swap the VFO A/B frequencies, at which point you will be hearing the pileup in full diversity and your VFO-A cursor will change to your XMIT frequency. You will tune through the pileup with your main VFO (VFO-A) to figure out where you want to transmit, and when you release the "REV" button you will again be listening to the DX station on VFO-A but you'll notice that your P3 VFO-B cursor (and TX frequency) will be wherever you placed it using the VFO-A knob while depressing the "REV" button. I don't claim that this is the ONLY way to accomplish this, but it is the way I have been doing it for years. A downside is that you will not be able to simultaneously hear the DX in one ear while hearing the pileup in the other. This makes sense though since diversity allows you to listen via two different antennas, with one antenna per ear. It takes a bit of practice, but it works well. 73, Dale - WA8SRA On Mon, Aug 3, 2020 at 2:27 PM Jim Miller wrote: > When using diversity what happens to the ability to do Split on the K3? > > Can I still listen to the pileup on VFO B and transmit on the VFO B > frequency? > > Thanks > > jim ab3cv > > __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

Re: [Elecraft] K3 Diversity RX question
Yes. When you use diversity you are actually not using the VFO B synthesizer for the second rx. They are both fed from synth A. VFO B remains available for transmitting. I do this all the time. 73, Victor, 4X6GP Rehovot, Israel Formerly K2VCO CWops no. 5 http://www.qsl.net/k2vco/ .

[Elecraft] K3 Diversity RX question
When using diversity what happens to the ability to do Split on the K3? Can I still listen to the pileup on VFO B and transmit on the VFO B frequency?

Re: [Elecraft] K3 Diversity RX
Ben, Full tracking (freq, mode, filter etc) is enabled with diversity on. Frequency tracking alone and leave the rest open, that is in the menu: config: VFO LINK I use them both under different circumstances, but that is not what you are asking. 73 Arie PA3A Op 6-5-2016 om 15:50 schreef w...@windstream.net: Retired now, so more time to "play radio."

[Elecraft] K3 Diversity RX
My K3 includes the KRX3, KAT3 KXV3A. On 160m and 80m, I use a shunt fed tower for TX/RX and a separate RX loop that goes through an RF limiter and external preamp to RX ANT IN. For Diversity RX, the loop has to be connected to AUX RF but it's then not available to the Main RX. In order to have the flexibility to use the RX loop with either the Main RX or the Sub RX for diversity, I built a switch box to route the loop to either RX ANT IN or AUX RF. A HOLD of the K3's RX ANT button toggles the antenna input to the Sub RX to the correct BNC. I considered using ANT2 on the KAT3 but it wasn't obvious that I could achieve the same flexibility. Other solutions to allow the RX loop to be available for both the Main RX or the Sub RX in diversity mode? My tower and RX loop are very close. The RF limiter protects the RX front ends from QRO. Caution! Your situation may be different. While in diversity RX you can operate split and also check your TX frequency with the REV button. Then use VFO A to find your spot. A very elegant design feature! 73 - Steve WB6RSE __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
[Elecraft] K3 Diversity Rx and antennas
I'm just waiting for the lovely lady at Elecraft to send me the gram for the sub-rx. In the mean time I'm contemplating the 2nd wire antenna to hoist up for diversity Rx. My QTH is surrounded by dense trees, cedar 120+ ft tall. Think planet Endor, ewoks, and pesky storm troopers around every corner. Now for the 2nd wire antenna, I was envisioning a Beverage because I can run 1000' wire over 7acres in a loop within 30' off the ground without getting snagged by the branches. Over 30' then I run into problems with very dense branches acting as barbs in the wrong direction preventing wire from going up. My main Tx antenna is a wire dipole at 25m cut and somewhat even on each side for 80-20m work. I'm tempted to take it down and make a new one for 160m + 80m-20m work. Anyway, the question is: for Diversity Rx, would a 15-25' off the ground Beverage be suitable? Or, does diversity work best if the polarization is opposite, -- among the variables involved with wire antennas, what variable to I look for to increase the benefit of having diversity Rx? Reply directly and I'll consolidate the responses here on the list. -jeff -- Jeff Wandling DE W7BRS K3 #2105 http://w7brs.com/k3 [EMAIL PROTECTED] ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
