Re: [Elecraft] What does the frequency readout mean?
Pete, N4ZR There have been some good answers for you. (I saved some to help others.) My answer(s) is to the way I read your question(s). The 'pitch' is the tone you will hear in your earphones, or speaker, on both receive and transmit (cw sidetone). It is nicely done in the K3. BTW, the 'monitor' knob adjusts the cw sidetone level as I recall. I haven't changed it in a couple years. Assuming you are in CW mode: --First, you have selected the 'pitch' that you like to hear. --You have 'CWT' on. --You tune a CW signal near enough to see a bar appear on the 'CWT' scale. --Press 'spot' and the radio automatically tunes the station in to your selected tone. --The signal will also be centered in the filter, and centered on the indicator. Once you get used to the tone you have selected, you will be able to tune well to that tone without using 'spot', or without looking at the display if you are rushed. However, the CWT indicator is your guide. And finally, you said, "I turn the RIT so that the received signal is lower frequency - say 200 Hz. I transmit. What does the station on the other end hear, assuming he is also using USB-CW? Does my "beat note" go up in his receiver, or down?" As others have said, the RIT does nothing to your transmit. But it does change your receive frequency, so that it changes the tone you hear. Not to be confused with the 'pitch' control. The 'pitch' control only selects the pitch you like to hear when the signal is centered in your filter. From then on, you want to tune the receiver to a tone of that pitch, or let the radio do it automatically for you. As for what the station on the other end hears, that is up to that operator, who will tune to one side of your carrier until he/she hears a tone that is suitable. If you are working a station with a radio that drifts in frequency, you will often need to make a correction to the tone you hear by using your RIT. That is it's function. It was a good question. I think you will enjoy it as you understand the workings.

Re: [Elecraft] What does the frequency readout mean?
Hi Pete, In CW mode, the K3 reads the actual transmitted frequency. Since normal CW uses lower sideband on the K3, this means that on 3507.2 in normal CW mode, with the pitch set at 500 Hz the suppressed carrier frequency is 3507.7 kHz (500 Hz above the signal frequency). If you change the pitch setting to 300 Hz, the K3 adjusts its suppressed carrier frequency to 3507.5 kHz so that the transmitted frequency stays on 3507.2 kHz. If you were using CW-R on upper sideband, the suppressed carrier would be at 3506.7 kHz with 500 Hz pitch, and on 3506.9 kHz with 300 Hz pitch. RIT has no effect on what the other station hears. However, if you use both RIT and XIT together, it will have an effect - exactly the same effect as if you rotated the tuning knob to produce the same tone in the receiver and the same frequency display in the VFO A display. If you are using the K3's normal CW mode, you tune "zero beat" to a station (i.e. so that what you hear is the same as your sidetone), and then you tune your VFO lower in frequency, the receiver's carrier frequency moves lower and gets closer to the signal you are receiving, so the pitch you hear goes down. If you now transmit with that lower VFO frequency, your signal will be lower in frequency than it would have been on zero beat, and therefore lower in frequency than the other station's signal. If the other station is also a K3 using lower sideband for CW, he will hear your pitch go up, because your signal is farther away from his suppressed carrier frequency. On the other hand, if the other station is using upper sideband for CW he will hear your pitch go lower. In general, if you are both using the same sideband, then when you move your main VFO (or RIT-XIT together) to change the pitch you hear, that will make the pitch the other station hears change in the opposite sense. If you are using opposite sidebands, what you both hear will change together. Since it is in general impossible to predict which sideband the other station is using for CW, it is likewise impossible to predict with certainty what he would hear if you were to adjust your transmit frequency slightly. 73, Rich VE3KI __ 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
Re: [Elecraft] KX3 ATU goes off/on during send?
Gernot, I take some of that back. If the macro output does not change, there still might be a problem with your KXAT3. I think my test is still worth doing, because if the output does change, then there would seem to be a documented problem to go to Elecraft Support with. Feel free to ask me for clarification, if I've confused more than helped. 73, Bob NZ9E -- View this message in context: http://elecraft.365791.n2.nabble.com/KX3-Upgrades-tp7570117p7570149.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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
Re: [Elecraft] KX3 ATU goes off/on during send?
Gernot,
Your KX3 might be behaving correctly.
E.g., when tuning across a band edge, the KXAT3 is designed to automatically
change to the last tuning of the new band. This is a feature, to save the
battery (don't need to retune just to change bands, if you've already auto
tuned on the new band), and to not clutter the spectrum with auto tuner QRM.
If you know that's not the explanation, say because you get the intermittent
clicks while staying within some band and don't tune outside that band, you
could try a diagnostic, by running the following macro in the "Elecraft KX3
Utility" app on your computer:
BN;FA;AK;
Run the macro once and note the output in the "Command Tester/KX3 Macros"
output pane. Here's some example output:
BN;FA;AK;BN01;FA3581500;AK002601;
This example output reports the VFO A freq (~3.58 MHz) and KXAT3 L, C, &
config settings. I.e., "AK002601" says there are currently no L's in the
L-net ("00"); C13, C9, & C8 are in-circuit for a total of approx. 454 pF
("26"); and some standard L-net configuration ("01") that I don't know
because the KX3 schematics aren't yet published.
OK, now use your KX3 until you hear the next intermittent click. Then run
the above macro again, and compare the new macro output with the old. If
the "AK" command output doesn't change (and you stayed in the same band),
then I don't know what is causing your clicking, but I'm thinking it's not a
problem with the KXAT3. If the macro output does change, I would contact
Elecraft Support for help. There are other diagnostics that can be run.
73,
Bob NZ9E

Re: [Elecraft] KX3 in the ARRL International DX contest
Add me to the list of KX3 ops in the ARRL CW DX Contest. I spent about 11 hours as HI/K8MR, operating with very simple wires from the Hard Rock Hotel & Casino resort in Punta Cana. Totaled 615 QSOs with 172 Multipliers. There were some very slow times for us, especially on the low bands, when European signals were booming in, much louder than stateside. But we couldn't work them in this contest :-( Best rate was an hour+ of 140/hr on 15 (and some 10) operating under a beach hut with a 10 foot piece of wire strung around the underside of the hut's framework. Precautions were used to protect the radio: I taped over all unused connecters and screw holes, and kept the radio in a ZipLoc bag, open only enough to get out the coax and keyer and headphone lines. Sent by hand and logged on paper from the beach! Night time operation (and late afternoon after the internal batteries ran out) was from the room with wires run from our fourth floor balcony. Jim, W8WTS, was also with me and shared time at the radio, using HI/W8WTS. I don't have his final results but I believe they were similar to mine. I was able to pack all the radio stuff in the equivalent space of slightly less than a carry on suitcase. (A few tools did have to go in checked luggage). Definitely a new horizon in contest expeditioning! 73 - Jim K8MR __ 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

Re: [Elecraft] KX3 in the ARRL International DX contest
Mike KC2EGL and I (John K3WWP) gave my KX3 (S/N 2325) a workout in the ARRL DX Contest also. I'd work a station, then Mike would work the same station in kind of a "two op two call one rig" operation or as we call it, "tag team operation". Between the two of us we made 599 contacts in 67 DXCC entities. Power was 5 watts for all contacts using my attic random wire, 20m attic dipole, 15m vertical dipole on the side of my house, or 10m dipole on my porch roof. We only worked a couple Asian stations (RC9O, C4N), but that was good enough for a weekend QRP WAC for which Mike got his NAQCC QRP Simple Wire Antennas WAC award. As a veteran of over 1,000 contests, I can say the KX3 tops any other rig I've ever used in contesting. Only a couple times in the whole contest (about 20 hours in our case) did we hear more than one signal in the passband (other than big pileups, I mean). There was virtually never any splatter into the passband from super strong signals even those only a few hundred Hertz away. I think the couple times we did hear any was because the other station's transmitter was at fault, not the KX3 receiver. * John K3WWP - 100% CW / QRP - Proudly promoting Morse Code: * * On the air with my KX3 #2325, K2 #6418, KX-1 #02101 * * As NAQCC VP - # 0002 FC # 1 - http://naqcc.info/ * * As FISTS Keynote QRP Columnist - # 2002 - http://www.fists.org/ * * With my CW-QRP site - http://home.windstream.net/johnshan/ __ 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

Re: [Elecraft] What does the frequency readout mean?
Pete. All Elecraft radios that I know about display the transmitted carrier frequency in CW and the suppressed carrier frequency in SSB mode. Your sidetone pitch setting is related to properly tuning a CW signal and knowing its frequency. If you tune the received signal to a pitch the same as your Sidetone pitch (that is zero-beat with the station), you will transmit on the same frequency as the station you are receiving (with RIT and XIT turned off). Turning RIT on will not move your transmit frequency, but will change your receive frequency. Turning XIT on will not alter the receive frequency, but will change the transmit frequency. I think of RIT or XIT as a 'mini split'. To add a bit more to the mental girations, the receive frequency displayed IS changed with RIT, so in order to determine your transmit frequency, you have to add or subtract the RIT offset (or just turn RIT off and you will see the transmit frequency in the display). With RIT on, what the display is telling you (assuming you used RIT to tune the station to zero beat) is the carrier frequency of the received signal. Simply changing the sidetone pitch setting without tuning the received signal to that pitch will accomplish nothing useful IMHO. 73, Don W3FPR On 2/19/2013 4:35 PM, Pete Smith N4ZR wrote: I'm having a hard time getting my head around this.

Re: [Elecraft] [K3] Sudden Hi-SWR on low end of 40M
There are two errors in my previous posting regarding the RCS-4 remote antenna switch. 1) The default (off, no power) antenna position is ANT4. The ANT1 position is the one that is activated by the AC control voltage. 2) I mistyped the RFC/choke value. The value of the RFC in the remote switch box measured with an AADE L/C Meter IIB is 70uH in circuit. It is probably the same as the RFC in the control box that measures ~100uH. Also note that the current version being sold by MFJ/Ameritron uses the three-relay circuit with a modified layout of the connectors, which I assume is to minimize any impedance bumps. The two-relay version I mentioned in the previous post has provision for jumpers that ground the unselected ANTx connector center conductors. Neither of the three-relay version support this feature.

Re: [Elecraft] How to program the K3 PF buttons to control a KRC2?
Craig: If you are unable to get the functionality you need using the PF1 and PF2 keys, another approach is to use a Microbit Webswitch model 1216H installed at the remote/radio site. The 1216H webswitch has five SPST relays with 230V, 16A contacts that can be controlled over the internet. The 1216H can also be setup with the 1216L rotor control unit (for Ham IV or T2X, etc.) using the same ethernet line. For details have a look at http://www.remoterig.com/wp/?page_id=166 Hope this helps. 73, Doug VE3MV - Original Message - From: "Craig - AE6RR" To: "'Jack Brindle'" ; Cc: "'Elecraft Reflector'" Sent: Tuesday, February 19, 2013 11:53 AM Subject: Re: [Elecraft] How to program the K3 PF buttons to control a KRC2?

Re: [Elecraft] [K3] Sudden Hi-SWR on low end of 40M
On 2/18/2013 9:54 AM, Terry Schieler wrote: Yesterday, during the CW contest, I noticed that my K3-100 (#474) suddenly began to "stutter" during CW transmissions on the low end of 40 meters. I hadn't noticed this before, including Saturday, the first day of the contest. My CW transmission had a "chattering" sound something like the brap of a machine gun (and no, my fist isn't *that* good). My first thought was RF getting into the radio, but, I've never had RF issues before and, again, nothing in the system had changed: K3 > LP-100A SWR/Power meter > 4 position Ameritron RCS-4 antenna switch > dipole. I've seen two versions of the RCS-4. An early version had three DPDT relays and a later version had only two 4PDT relays. My comments here apply to the two-relay version. Which ANT position on the RCS-4 connects to the 40m dipole? If position 4, your remote switch may be failing. In that position the control voltage imposed onto the coax center conductor along with the RF is alternating current, which activates both relays in the remote switch. If the coax connections are not solid for any reason, or if either of the filter capacitors across the relay coils is bad, one or both relays may be chattering. You can check this by selecting antenna 4 and listening to the remote switch box. If a relay is chattering you'll hear it. There's no need to apply any RF for this initial test, but if there's no audible response apply a steady carrier in the troublesome frequency range and listen again. There could be an unwanted resonance due to changes in the RFC (~7-100uH) or the capacitors that triggers the event.

Re: [Elecraft] K3 P3 Spurious signals
Tried another BNC cable I had here and it knocked the problem down appreciably. Without an antenna connected (well, a 6' piece of RG8) I can barely see them on 40m - they are non existent now on 10m. With my antenna connected, I can't see them at all anymore - well below the noise level I have here. The cable I tried has connectors that fit much tighter (no wiggling at all) than the Elecraft supplied cable. So I'm not sure if it is the connectors or a bad crimp as others have suggested. I may tear my P3 down at some point to look at the case grounding and clean them up. This may help even further if there is a grounding problem. 73, Dave W8FGU On 02/18/2013 06:23 PM, Dave Van Wallaghen wrote: Fred and I discussed this problem off line a couple of weeks ago as I have the same thing here.

Re: [Elecraft] Adapter to use KXUSB with the KPA500
Heck no! I want connectors that have solid positive contact and are captive. The 3.5mm connectors and 2.5 mm connectors may be fine for portable rigs. For fixed station use the bigger the better for connectors. 73 de Brian/K3KO On 2/18/2013 10:44 PM, peterc281 wrote: I have just completed the firmware upgrade on the KAT500 and found it a breeze with the supplied KXUSB cable.
