[Elecraft] K3 with internal 144XV 2 meter transverter
If the internal transverter is adjusted for 1.0MW output max, what power should I see out of the rig at antenna connection 3? RF power on Meter shows full scale but that is in Milliwatts not watts. Also display just says ANT, not ANT 3 or should it. Thank you.

Re: [Elecraft] [K3] Fan noise cure
Hi Bob, it sounds really interresting. I realized that my K3 after huge upgrade and now is really fully loaded is quite hot even in idle (RX mode). The PA/FP temp is stabilized to 38-40C in RX idle when the FAN1 speed is selected but when I touching the cabinet sides it is quite hot. So the more CFM powerfull and even quieter fan looks like great upgrade.

Re: [Elecraft] RTTY on the K3S
Hi rich and all. Maybe you have selected the wrong audio output device. You need to change it accordingly to the new K3S USB audio interface that appeared when the USB was inserted ... and the driver was inserted. Maybe you have the audio generator AFSK level (inside the program i.e. MMTTY) or the USB audio level for the proper interface way down. But, more ... that's the best candidate! Maybe you have something other wron as you wrote that you are getting a pure carrier. This would mean that you are still setup as FSK and are getting the mark carrier without the diddling to shift carrier ... this mean that yours radio still wait for FSK manipulation and not for the AFSK tones in input. Having the radio properly setup for AFSK audio tones input will give you nothing when in TX without tones, no carrier I mean. No audio no RF ouput. The AFSK audio tones gives you the proper RF output as on SSB. Contrarily when you have the FSK submode setup you get plenty of RF but no diddles if there is not manipulation in between tones. UR radio is FSK, UR computer is AFSK. Isn't? I would double check the Radio SubMode and after the interface, levels setups whatever they live. Have a check and let us know, pse. 73 de iw1ayd Salvo PS use again the Joe's advice and list on the radio side. SubMode seems to be the key in your case at least from here. >Message: 27 >Date: Tue, 11 Aug 2015 20:16:18 -0700 >From: KE1B >To: elecraft@mailman.qth.net >Subject: Re: [Elecraft] RTTY on the K3S >Message-ID: <4da7b493-9c16-4231-8664-0cdd25e8d...@richseifert.com> >Content-Type: text/plain; charset=us-ascii >On Aug 11, 2015, at 6:17 PM, Joe Subich, W4TV wrote: > > On 8/11/2015 8:56 PM, KE1B wrote: >> >> Is there any way for the K3S to take its audio from the USB codec >> rather than the Line-in or Mic-in? > > Exactly the same configuration as AFSK with audio via Line In but > no connection to the Line In jack. > > Mode = DATA > SubMode = AFSK A > MENU:Mic Sel = Line In > Mic gain set for four bars of ALC with fifth bar flickering > >I have that configuration, but when I transmit, I only get a pure carrier, no >data diddling. >Rich KE1B __ 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] RTTY on the K3S
Following up on Salvo's post: Rich, I believe you said you are using N1MM+. If that is the case, open the N1MM+ Configurer, select the Mode Control tab, and on the right side, look to see what is selected for "Mode sent to radio" for RTTY. If this is set to RTTY, N1MM+ will put the K3S into FSK D mode, which will result in an unmodulated carrier if there is nothing connected to the FSK pin on the AUX connector on the K3S. To use AFSK A, change the "Mode sent to radio" to AFSK. 73, Rich VE3KI IW1AYD wrote: UR radio is FSK, UR computer is AFSK. Isn't?

Re: [Elecraft] P3 TX Mon question
Assuming you have separate antennas for each K3, my guess is that the power is actually coming in from the non-transmit antenna. To the directional coupler, that would indicate as a high SWR - no power from the transmitter, but power coming from the antenna equals infinite SWR. 73, Don W3FPR On 8/12/2015 10:09 AM, W4CCS wrote: Sorry, I did not answer your question..

Re: [Elecraft] New P3 TX Monitor....unusual behavior with SWR (at times)
Mike, Thanks for the comment. I only have one K3 with one P3. My configuration is: K3/P3 —> KPA500 —> TX Mon Sensor —> LP100A Sensor —> KAT500 —> 80-meter Dipole I first noticed the spike with the RED LEDs on both the KAT500 and the KPA500. I was not looking at the SWR display on the P3 although the second time I did notice that it too spiked (max reading). Like I said, I was operating CW and when I sent just the first dit of a QNI into a CW net the spike occurred. I stopped, and then keyed again and everything was normal. The second time that I did this, I thought that maybe the spike was momentary and continued keying but the second or third key down action (actually, a paddle) resulted in fault with the KPA500. Last night, I did not have any problems at all because I disconnected the TX Mon sensor. I will continue experimenting though as I don’t have too many data points yet to draw conclusions. 73, phil, K7PEH > On Aug 12, 2015, at 7:28 AM, Mike VE3YF wrote: > > Phil: > > I have the same setup but only 1 x P3.

[Elecraft] P3 TX Mon Usefulness?
Now that I have the P3 TX Monitor I am wondering if this is anything more than a mere light-show for entertainment. I am mostly CW and I find that the actual TX display of the CW to be a bit silly looking and contrived. In fact, it looks like something fake to me and I say that not as a criticism so much as a curiosity in wondering what the display actually shows. I have adjusted some of the TX Mon parameters to adjust the “size” of the envelop display but I still am not sure I understand exactly what I am seeing and if this has value other than ham radio eye candy. Maybe I need a chapter added to the P3 writeup by Fred Cady (KE7X) describing the meaning and analysis of wave shapes. I actually like the power (peak power indicator) and SWR display but not sure I would get rid of my LP-100A as a result. No, I am not regretting the purchase, just wondering about the value of the display. From my very few experiments with SSB and the TX mon, I see a more interesting display but certainly I can’t easily tell if what I see tells me anything useful to know or useful in analyzing signals from the K3. Now, if I could hook up the P3 TX Monitor feature to my Eico 720 CW transmitter and see the wave shape of CW signals I might discover the major chirps that my 720 produces — But, a K3, it is near perfection in CW shaping (or, at least to me it is).

Re: [Elecraft] P3 TX Mon Usefulness?
You *can* hook up your Eico 720 Tx and see its CW rise and fall times and perhaps use that information to dig into the radio and improve it. In SSB mode you can see the effect of the K3 Tx EQ and speech processor as it relates to peak-to-average power. And as you say it provides PWR and SWR indications. With multiple indicators (K3, P3, LP-100A, KAT500, KPA500, ...) you can pick the one you like the best -- or worry about the slight discrepancies in their displays :-) And, who knows what future enhancements might come along... 73, Lyle KK7P (who is not aware of any enhancements at this time, but is cognizant of Elecraft's track record in this regard) Now that I have the P3 TX Monitor I am wondering if this is anything more than a mere light-show for entertainment... __ 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] P3 TX Mon Usefulness?
I am not regretting my decision to buy the TX Mon — and, I would buy it again if needed. Lyle’s comments were good to hear — maybe Lyle should write a new chapter in the P3 Owner’s Manual on the analysis of signals using the P3 TX mon. So far, the only information in the manual is how to setup parameters and a few other things — necessary and important but not yet sufficient to a full understanding. I have a W2 meter though, also a W1. I use the W2 with all my QRP or other rigs. I have one W2 sensor but I switch that between my three major other rigs. 73, phil > On Aug 12, 2015, at 10:11 AM, Doug Turnbull wrote: > > Phil, >I do not yet have the TX monitor but in time will.Whatever the > usefulness and it seems Lyle has answered this question, it is a feature > which many users clamored for.

Re: [Elecraft] P3 TX Mon question
It would appear that the display needs an option to gate the display with the equivent of local TX asserted so it only responds to its own transmitted signal. An option because others might want to know that their TX signal was coming back at them on another coax. Or perhaps set an adjustable gating power level defaulted to one watt. 73, Guy K2AV On Wednesday, August 12, 2015, Alan wrote: > The transmit sensor in the P3 TX monitor trips at only a few tenths of a > watt (a few watts with the 2 kW coupler).

Re: [Elecraft] P3TXMON Bug?
It actually does go back to split screen spectrum/waterfall in receive mode. In transmit mode the spectrum display is replaced by the modulation waveform, but the waterfall remains on the screen. There are two reasons why the "meters" remain on the screen in receive mode. One is that it would be pretty annoying when sending CW QSK for example to have the window jumping up and down every time you key. The other is that it would require re-drawing the waterfall every time you go to transmit mode, which would lose all the waterfall data. I think many people like to be able to look at the waterfall while transmitting to see where the signals were the last time they were receiving.

Re: [Elecraft] P3TXMON Bug?
Alan, Since "optional" would be the idea, and that the P3 must know (or could know) what mode the K3 is in, why not make it selectable if not in CW mode? It sure seems like us folks that want it to swap in and out, are comfortable waiting a few seconds for the waterfall to update. It seems half baked to me the way it is. You already swap the modulation waveform in and out, why not the rest? Otherwise, is there a way to fire macros from the K3 to the P3 when going from TX to RX and back? Or maybe fire them from within the P3 itself? Then I guess we could do it ourselves.

A spectrum analyzer is the best way to tell *if* something is wrong, but a time-domain display of the modulation waveform is the best way to determine *what* is wrong. You can easily see if the key clicks are due to too fast a rise time, too fast a fall time, incorrect key shaping, flat-topping in an external amplifier, insufficient bias in the amplifier, parasitic oscillations, etc. With a spectrum analyzer you can only tell that the clicks are there, not what is causing them.

Re: [Elecraft] P3 TX Mon Usefulness?
Jim and all, I agree, the *best* way to look at keying is in the frequency domain, but for those who do not have that capability, the time domain keying waveshape can be beneficial. The P3 TX MON option does not show the frequency domain, but it can display the rise time and fall time of the CW keying envelope. Those rise times and fall times (as well as the shape of the rise and fall slope) are a good key to the cleanliness of the keying - the P3 TX MON does provide that capability. Whether the viewer can interpret that information clearly and correctly to determine good/bad keying is another question. There is information available on the web showing good and bad keying waveshapes. The figures in the Elecraft K2 Keying Waveshape Mod instructions is one such document. An additional monitor receiver with an IF tap and equipped with a P3 would be necessary to view the frequency domain of the CW signal. Quite possible for those who have 2 K3s (or K3S) and at least one equipped with a P3, but that is not the "average ham". While the P3 does show the received signal in the frequency domain, that is developed from the IF frequency of the receiver. The TX monitor sits on the transmission line and must respond to the entire range of ham band frequencies. To expect the TX Mon option to convert any transmit frequency to a frequency domain display is just not reasonable given today's technology. 73, Don W3FPR On 8/12/2015 6:20 PM, Jim Brown wrote: Besides, the time domain (rise/fall times) is the wrong way to look at keying.

Re: [Elecraft] New P3 TX Monitor....unusual behavior with SWR (at times)
I find this thread quite interesting. I too have been dealing with VSWR "spurts". My TX lineup is similar to Phil's, but I don't have the TX Monitor. After a recent station rewiring job I found I was having a great deal of trouble with indicated VSWR jumping to high levels with the amplifier on. The problem was especially bad on 80 meters -- anything above about 300W would randomly give a high VSWR fault on the KAT500. Since the KPA500 was feeding the suddenly changed load it too would usually fault out. The sensor for my LP-100A is on the antenna side of the KAT500, and its VSWR indication was rock solid during these events. My station is in an extremely difficult RFI environment, with seven antennas crammed onto a 0.2 acre city lot. I immediately suspected that common mode RF was getting into the reverse power sensor circuit in the KAT500. I installed a Balun Designs choke on the antenna side of the LP-100A sensor and the KAT500 stopped giving the high VSWR indications right away. That's the good news. The bad news is that now the KPA500 is doing it, but at considerably higher power levels. I can run around 400W out before the KPA500 begins to randomly show VSWR faults. The KAT500 is completely stable at full power. For now, I'm living with this situation. So I would suggest the troubles you're seeing may be the result of common mode RF problems on the transmitter feedline. It could be that the addition of the extra electrical length of the TX Monitor sensor and its associated cabling changed things just enough to put a common mode voltage node near the KAT500 output port. You might try adding an additional piece of coax somewhere in the lineup and see if that changes the situation. RF is funny stuff. 73...

Re: [Elecraft] P3 TX Mon Usefulness?
Not if you're looking at an Eico 720. It will be difficult to identify keying sidebands amongst the drift and chirp.

Re: [Elecraft] New P3 TX Monitor....unusual behavior with SWR (at times)
Randy, If your LP100A is on the antenna side of your KAT500 then you are putting your LP100A in the region of higher SWR if your antenna is not close to resonance. I think you would want to put your LP100A in the inboard side of the KAT500 so that you are properly showing the “tuned” SWR on the LPA100A and your readings will be more accurate I believe. If you want to know the antenna side of the SWR, what the KAT500 refers to as the Bypass SWR since it is the SWR you see if you bypass the KAT500, then you can use the KAT500 utility program to display that. I am not seeing the problems you describe. For example, when I run without the TX Mon Sensor in place, there are absolutely no SWR problems at all (look again at the configuration below that I have). I should also note that today I did not see any problems with the SWR spurts I originally reported even with the TX Monitor sensor inline. 73, phil, K7PEH > On Aug 12, 2015, at 7:48 PM, Randy Farmer wrote: > > I find this thread quite interesting.
