David, I can confirm that on the K3, the VOX Delay DOES work, regardless of whether the TX Gate is engaged or not. 73, Dale, WA8SRA > Anybody? > > 73 > > David Anderson GM4JJJ > > >> On 9 Jul 2016, at 19:07, David Anderson via Elecraft >> wrote: >> >> I have a KX3

[Elecraft] OT: Online book - Crystal Sets to Sideband

This very nicely done book by Frank W. Harris K0IYE, "Crystal Sets to Sideband", is likely old news to many, however I just learned of it and thought those who enjoy home brewing and/or amateur radio nostalgia might find it enjoyable. You can read the book online via the url below, or download

Re: [Elecraft] [PX3] Does not respond to the knob being rotated

Steve, Just another data point ... My PX3 exhibits the same behavior in a system that includes the KXPA100. I see it happen when I twist the KX3's OFS knob to quickly QSY. However, if I turn OFF the the KXPA100 via the KX3 "PA MODE" menu option, the PX3 responds immediately to a twist of the KX3

Re: [Elecraft] PX3 Problem?

Dave, make sure that the preamp is engaged on your KX3. If the preamp is off and you are receiving on a quiet band, you'll see "stuff" that would normally be covered by the band noise. Turn on the preamp, and the artifacts that you're seeing should be pushed below the noise floor of just about any

Re: [Elecraft] external waterfall

If you want to turn off just the waterfall on the external display, you'd use the P3 "SVGA menu" > "SVGA WfEn" menu option. With that "SVGA WfEn" option showing, tap the "SELECT" knob, and then ROTATE the SELECT knob until you see "Waterfall off". Then tap the SELECT knob to save your change. 73,

Re: [Elecraft] 1 Khz filter

Hello John, It's used for CW. I have a pair of them (main and sub rx) and find that CW sounds more pleasing through this filter. I operate about 90% CW and I use this filter most of the time, engaging narrower filters only when it becomes really necessary. 73, Dale -- WA8SRA On Tue, Jul 25,

Re: [Elecraft] Beam antenna question

I agree 100% about the hex beam; I had the original Traffie 20m monobander and now have the K4KIO broadband 5-band hex beam. Both work extremely well on their designed bands. However -- it has been my experience that a 5-band hex beam works great as a very low-noise receiving antenna on 40m and

Re: [Elecraft] Diversity and RF/Vol Controls

Hello Rich, I have been using diversity reception on the K3 on 40m for years, and can control both RF gains separately, and the AF Gain controls are set so that the larger one acts as a balance control, and the smaller one acts as a master volume control for both simultaneously (however that can

Re: [Elecraft] K3(S) QSK Operation

Scott, The new KSYN3A most definitely DOES resolve the old jitter issue. I updated my both of my synths as soon as the new ones were available, and even without QRQ engaged, the cw timing is jitter free. If the new KSYN3A did nothing else, I'd have still bought them just for the great cw

Re: [Elecraft] DXE NCC-2 & K3/K3s

Hello Gary, I don't have an NCC-2, however I've been using it's predecessor, the DXE NCC-1 (very effective product) with my K3 for about 6 years. I'd be glad to share my experience with the NCC-1 / K3 combination. 73, Dale - WA8SRA On Fri, Nov 24, 2017 at 6:46 PM, Gary Smith

Re: [Elecraft] K3 / RF gain - S meter issue

Hello Bruce, Just to rule out any electrical or mechanical discontinuities in the RF gain control itself, you can use the CONFIG > SW TEST > SCN ADC option to examine the ADC reading as a function of rotation position for both RF gain pots and both AF gain pots. In order to be able to see the "SW
