Re: [Elecraft] K3/0-Mini - Experiences?
YahŠ it sucks. I knew when I moved to an apartment that staying on HF was going to be a challenge, but I was not prepared for the breaker issue. I found that with my kx3 and a wonderwand wonder loop on my kitchen table, that with 10 watts I can do some jt65 and wspr on 20m without popping the breakers. But my success has been limited and not worthwhile. I¹ve been a remotehamradio user for almost a year now, but I don¹t have much interest in ssb or cw these days. Remotehamradio does have a beta test going on for ³logging² software such as ham radio deluxe. I¹ve tried jt65 over it, but haven¹t had consistent results and get disconnected or have HRD lock up. I¹ve been avoiding buying a K3/0 for some time, just because I didn¹t want to spend the money on a ³non radio² device. But if I¹m going to get back on jt65, I think its my best option.

Re: [Elecraft] K3/0-Mini - Experiences?
I recall reading something in an ARRL publication or newsletter that at least one manufacturer of AFCI breakers has addressed and corrected the problem of RF susceptibility. That company is Eaton. It is a bummer that consumers must suffer from products that do not have sufficient RF immunity. If all manufacturers would 'step up to the plate' and accept that we live in a world where RF is present, often in strong fields, we would not have a problem. Hams are not the only cause of RF problems - think of the problems encountered by those who reside near broadcast stations. RF fields are emitted by police, fire and other emergency service transmitters. IMHO, more manufacturers must be willing to design products that can withstand reasonable RF fields. Of course, most consumers do not understand that, and the ham is to blame. There was a parallel back in the 1950s and 1960s with television interference when many TVs were designed with front ends and IF chains that would pick up RF on most any frequency, much to the consumer's dismay and blame placed on the ham, even if his transmissions were clean of harmonics. It just about drove operation on 15 meters off the air because many TV sets used a 21 MHz IF that was 'wide open' for interference. 73, Don W3FPR On 5/30/2015 4:13 PM, ab2tc wrote: Hi, Sorry, I don't have a K3/0, but your problem certainly caught my interest.

Re: [Elecraft] K3 FSK power transients
Today I put the old Bird wattmeter in line and found that the average power out of the K3 does *indeed* drop down and become somewhat erratic in fsk441 mode. As noted previously the PEP output stays the same although my watt meter shows some erratic behavior. So my wattmeter is telling the truth. And my K3 has a problem. (I tried different computers and sound cards - all the same). The power fold back is in FSK441 and a similar mode called JTMS. Modes that vary the tone more slowly - JT65 and JT6M - do not cause the same large power drop (minor fluctuations in power only). To use an separate receiver I had to switch from 50 MHz to 28 MHz and there I eventually found that if I run 12 watts (final amp not switched in) then the PEP/Average is quite near 1:1 (or 10:10). Its only when I go to a power level where the final is required, that I get this strange effect. I get quite a high PEP/Average ratio on voice too, but it does not sound bad ... The final still produces plenty of power, so it is not fried. I went through and repeated the transmitter gain calibration - to no effect. So I guess I am going to contact Elecraft on Monday. 73 Ken -Original Message- From: Joe Subich, W4TV [mailto:li...@subich.com] Sent: Friday, May 29, 2015 3:12 PM To: Ken; elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 FSK power transients But I stand corrected on the average. I was computing an average of the crest, not the effective value of the wave. Since these are sine waves, the effective value is 0.707 of the crest. Of course, when the crest value is varying over the period under consideration, you might want to average the crests and then multiply by 0.707, which is kind of what I was doing. That is not the definition of peak to average in the RF domain. For a CW (sine wave modulation) signal, the peak to average ratio is 1:1 or 0 dB. Since FSK (specifically, in this case FSK-441 - which is 4FSK) is a sequence of sine waves, the theoretical peak to average ratio is 0 dB. Now, if you introduce AM into the FSK modulation, e.g., some tone or tones have different levels, the crest factor departs from 0 dB. In this case, Peak Power (or PEP) is the maximum average peak (CW) case and average power is the longer term average of the peak power. In a linear system, PEP is the CW (single tone) power while average power - per FCC definition is the value to which a capacitor would charge based on multiple peaks (or the average of the peaks of the modulation). For 4FSK where three of the 4 tones were 1.4 V Peak (1.0 V RMS) while the fourth tone was 1.12V (0.8 V RMS), the average voltage would be: (3 * 1.4 + 1.12)/4 or 1.33 V Peak. The Peak voltage is the highest of the four tones or 1.4 V. Thus the Peak to average ration for a 4FSK signal with one tone at 80% of the other three would 1.4/1.33 - or 0.45 dB. I'd strongly suggest you get an audio oscillator with a known, stable output level, pick one tone - either 1323 or 1764 Hz - and run it into you K3, set the mic gain to 4 bars of ALC and measure the CW output power at that frequency. Then, without changing the audio level or mic gain, measure the CW level of your K3 at 882, 1323, 1764 and 2205 Hz. My guess is that you will find that one tone or another produces significantly less power than the others - probably because of a filter alignment or ripple issue. 73, ...

[Elecraft] P3: VFO Cursors in WF
Would there be any support for a P3 option to display the VFO cursors in the waterfall area? The WF is mainly what I watch, I can see signals there that I'd never find in the spectrum display [and sometimes can't hear either :-)]. Admittedly mainly in contests, I will find a trace in the WF area, I'll try and put the VFO over it, I usually miss a bit if he's gone for a few moments, and with 150 or 200 Hz BW, I'm usually not close enough to hear him when he comes back. FWIW: I use the monochrome waterfall option, I don't have any idea how this might play out for folks with normal color vision ... could be way off base with this idea. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org __ 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 TX DELAY
Expecting a transceiver to somehow neutralize all amp obsolescence is putting the burden where it doesn't belong. And it really can't come close to doing the entire job. Existing mod kits from Harbach, W7RY, etc, can convert many older amps internally (all the way back to SB200 SB220) to *excellent* modern status, QSK, modern interface voltages and behavior, good for years of slick operating to come. Array Solutions has an excellent external QSK device, for those who don't want to tackle an internal mod. You didn't say which specific amp with slow frame relays. Many (most?) of these were designed back when the expectation was something like a footswitch or a toggle switch would be used to place the shack in transmit mode. I own an FT1000MP. On CW (only) it has a first in first out bucket brigade delay (menu 7-4 keyer break-in time) which allows it to apply T/R assert to the amp and allow continuously delayed CW up to 30 ms to be transmitted from the MP. With the clunkier amps actually needing the max 30 ms delay like my older AL1200, you had to listen to the input monitor on the MP if you were sending with a key. Listening to the actually sent signal would is so divergent from physical input at 30 ms that many simply can not send CW with it. But it doesn't fix the parallel problem on SSB. Even if the MP's delay was working OK for CW, there is no delay for SSB. This would require a continuous bucket brigade voice delay with sufficient fidelity. That isn't impossible, but a lot more expensive and complex than a faster relay. And it STILL does NOT fix all the issues of clunk involved. This includes the recovery time from T back to R so slow that in contests often the first baud or two of a reply would be lost while the relay is waiting for the contacts to restore the RX path through the amp, which now only has the spring to propel points to normally closed state. IMHO to put it bluntly, any amp relay with T/R duties that won't close in 8 ms is obsolete and needs to be replaced by something modern. The aftermarket mod boards will modify old tube amps for QSK, low voltage low current T/R keying (soft key), step start power-on etc. Amps modified with current QSK circuitry will switch quickly enough to support VOX on SSB. All the Ameritron amps have superior aftermarket QSK mods available, in addition to the manufacturer's own QSK option. W2CS helped me QSK my AL1200 with the same circuit he used to upgrade his SB220. This was before the current crop of excellent mods were available. No excuses. 73, Guy K2AV On Saturday, May 30, 2015, David Raymond daraym...@iowatelecom.net wrote: I'm running an older borrowed K3 to get various I/O issues worked out while awaiting arrival of my K3S.

Re: [Elecraft] K3 High Level Digital noise
Usually this kind of thing is external to the K3, very often mechanical. Often happens when something external is rearranged. Remove *everything* connected to the K3 except the power and a dummy load. Make sure the power voltage is normal. See what you get then. If you still have noise, put an AC voltmeter across the DC power leads. Come back with the results. 73, Guy K2AV - While transmitting, my K3 developed a high level noise.

Re: [Elecraft] P3: VFO Cursors in WF
Sounds like a great idea. That would be a great aid for teaching on the GOTA station. 73, Fred, AE6QL -Original Message- From: Fred Jensen k6...@foothill.net Sent: May 30, 2015 8:09 PM To: Elecraft Reflector elecraft@mailman.qth.net Subject: [Elecraft] P3: VFO Cursors in WF Would there be any support for a P3 option to display the VFO cursors in the waterfall area? The WF is mainly what I watch, I can see signals there that I'd never find in the spectrum display [and sometimes can't hear either :-)]. Admittedly mainly in contests, I will find a trace in the WF area, I'll try and put the VFO over it, I usually miss a bit if he's gone for a few moments, and with 150 or 200 Hz BW, I'm usually not close enough to hear him when he comes back. FWIW: I use the monochrome waterfall option, I don't have any idea how this might play out for folks with normal color vision ... could be way off base with this idea. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org __ 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 fptowns...@earthlink.net __ 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
[Elecraft] K3S and CW Skimmer's 24 kHz limitation
Just an FYI for anyone interested. Several years ago I opted to use Blind Skimmer's waterfall because I found it so convenient for fast SP (due to Skimmer's ability to quickly jump to *exact* zero beat...see video below). https://www.youtube.com/watch?v=uZDXuOgUQJ0 I asked Alex VE3NEA if the new K3S might change the 24 kHz limitation (Softrock on IF mode). Below is his response. 73, Bill W4ZV Hi Bill, Sorry for the late reply, I have just returned from a 2-week trip and started to answer my email. No, the presence of the USB and RS232 ports in the radio does not change the bandwidth processed by CW Skimmer in the IF mode, sorry.

[Elecraft] K3 no xmit, no receive?
Hola, I was scheduled to operate my K3 as a remote for the WPX contest. Problems with VPN at remote site delayed that setup. As contest time approached, I decided to deploy my Buddipole out the apartment window and was gonna play around with 100w and dipole config.on 15m. However, I could not hear any signals, at all. Nothing but white noise on all bands. The Buddipole ends in a BNC which I had connected to adaptor for PL259. Tried Ant 1 and Ant 2 with no luck. Thinking adaptor may be bad, I hook BNC to RX in but no sigs there. This morning, more troubleshooting, I discovered that there is no power out (although I was tricked as ATU was finding perfect SWR , HI). K3 has not been used for over a year and when I brought it to HP, it was inside my rollaboard so I had a watchful eye on it during the trip. The only thing I can think of, is perhaps one or more of the circuit boards was dislodged due to vibrations of rolling around the airport or within the airplane(s) themselves. 9 hours on B767 then 3 on a B737. Before I open up the K3 and start messing around inside. any suggestions or tips on where I should start? I am thinking of pulling circuit boards then resetting them, just in case one or more was 'jiggled' loose during transport. 73 Tom HP1/K6CT aka CX7TT -- __ 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
[Elecraft] K3 no xmit, no receive?
Tom, Since you receive white noise, before you dive into the K3, consider that there is an item that is common to all three antenna inputs. - The BNC connector and coax to the BudiPole. Try another independent antenna into the antenna input you have active. Just a few feet of wire as an antenna will give you some signal reception. Then try transmitting into a dummy load using a completely different coax and connector. Just suggestions. 73, Jim Wilson __ 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
