[Elecraft] [K3] Sticky NTCH and Auto SPOT failure

Hi all, I am sending my apologize for maybe stupid questions... but I am interesting in you opinion and comments please. Is there possibility to set sticky notch filter (NTCH) in general at least or even better per band please? I am really worried to set NTCH always again after turning K3 on. I

Re: [Elecraft] Issue Resolved K3 Voltage on TX

If you operate SSB, you might want to run higher voltage at the K3 terminals (e.g. at 14.5V which is below the 15.0V spec) to minimize IMD. This was discussed extensively in 2009 but the following by W4TV is a good summary: > Is there something critical in the

[Elecraft] K3S In-Depth Review Coming Soon?

I was wondering if and when a full-on review of the K3S would be forthcoming. I'm a bit surprised that following its release there hasn't been a lot of reviews posted (certainly no comparison to the number of reviews that followed the release of the original K3). A comprehensive review of the

Just got a new PX3 kit and assembled it last night. What a great addition to the KX3 station; thanks Elecraft. I have been seeing the posts about a keyboard and downloaded and installed the Beta firmware into the PX3. I had a wired Logitech K120 keyboard and plugged it into the PX3 and now I see

Operators disagree about K3/K3S audio. To me it sounds great, others dislike it. The best way to settle the question for your own, personal ears, is to find someone nearby who will let you use his/her K3S for a few hours. 73, Vic, 4X6GP/K2VCO Rehovot, Israel http://www.qsl.net/k2vco/ On 27

[Elecraft] K2/10 PS voltage vs IMD? (was Re: Issue Resolved K3 Voltage on TX)

(My apologies if this has been covered and I missed it in the archives.) Would the 14.5V recommendation also apply to other Elecraft rigs (in my case a K2/10) for best IMD perfomance? Are there any tradeoffs in other areas at that voltage vs. 12.6 (i.e. battery) or 13.8? TNX/73, Al On Tue

Re: [Elecraft] K3S In-Depth Review Coming Soon?

The recent ARRL review of the upgraded synthesizer performance is available in the current issue of QST. That, by far, is the biggest change in the K3S vs. the K3 (not that there aren't other changes, such as cw performance, LF rx, etc.) 73, Bob/AA6VB From: Mike K2MK

We've made several changes to improve audio over years, and a K3S incorporates all of them: - K3: improved 12VDC decoupling to the AF amp - K3: added a dual low-noise LPF to eliminate residual sampling noise (mostly at 12 kHz) - K3: corrected DSP AGC algorithms, which were non-monotonic at

[Elecraft] K3 - PSK31 - AGC/No AGC

Hi guys Old topic from a Old Newbie. I have been fooling around with PSK 31 and I have it set up and working but I do have a question. Do most ops using this mode turn off the AGC and then ride the RF gain control because of the stronger signals in the band pass killing off the weaker

Re: [Elecraft] K3S In-Depth Review Coming Soon?

​ Audio quality seems to be a very individual matter of taste. The language of audiophiles looks to be rivaled only by that of wine experts in trying to describe their taste. Radio communication audio doesn't have near that complexity, but there does still seem to be a lot of personal taste

Re: [Elecraft] K3S In-Depth Review Coming Soon?

When I first got my K3, I was very disappointed by the receive audio. Hissy etc. I think everyone knows what I am talking about. It was not my friend for a very long time. It took me months of experimenting with the various menu settings and speaker selections, but I eventually turned the K3

Re: [Elecraft] K3 - PSK31 - AGC/No AGC

Lee, I do not turn off the AGC, but instead use the filters to isolate the signal of interest with the Width and Shift controls in the event that a strong signal is monopolizing the waterfall. Yes, you can do it your way, but I believe my way will allow you to copy weaker signals easily.

Re: [Elecraft] K3 - PSK31 - AGC/No AGC

I only work PSK on occasion. I do work a lot of RTTY tho...like V73D on 10M about 5 min ago. I never turn AGC off on any mode. Never understood why anyone would want to but I've only been licensed for 57 years, so maybe I missed something. On 10/27/2015 3:32 PM, Leroy Buller wrote: Hi

What Don says, plus if you're using a sound card interface (any flavor) to decode the digital, keep the LIN OUT low (mine is set to 1, zero is off) THEN keep the audio as light as possible (driver software) into the computer decoder. What you want is to NOT let the sound card AGC get

Re: [Elecraft] K3 - PSK31 - AGC/No AGC

When I was using a SignaLink, I used the RF gain control to keep strong signals from overloading the input to the computer. I would also use the Shift and Width controls to isolate a signal, and got a 250 Hz filter to help. Dropping the RF gain control until the band noise almost disappeared

Re: [Elecraft] K3 - PSK31 - AGC/No AGC

I do run a fair amount of PSK-31 and much enjoy the same. In that regard I always run AGC-F. For selectivity, in dealing with strong signals in the midst of weak signals, I shift the passband and tighten the bandwidth as needed.RF gain is always adjusted based on band noise such that

Re: [Elecraft] K3 - PSK31 - AGC/No AGC

I run the K3 with AGC-Off in all digital modes and rely on the roofing/DSP filters to edge out really strong signals. Most of the time the software will compensate in pulling the weak signals out of the mud a lot better than your rig making them louder. I would suggest playing with each setting

Re: [Elecraft] K3 - PSK31 - AGC/No AGC

Older receivers (like my HRO-5) used a beat frequency oscillator (BFO) operating on the same frequency as the I.F., offset only by the audio beat note required. That meant that a huge local signal (the BFO) was blasting into the I.F. strip. AGC was derived from the RF signal at the "second

Yes but... Those receivers didn't have product detectors and BFO leakage into the AGC detector was an issue. .On 10/27/2015 6:01 PM, Jim Brown wrote: In those older days, it was quite common for CW ops to turn down the RF gain and turn up the AF gain. In effect, this more or less
