Re: [Elecraft] P3 Beta Firmware
Hi Jim, I am running the 1.35/1.22 firmware but I haven't tried the NB feature. My interest was in the SVGA hang-up going from transmit to receive. In that regard this version is 90% better than 1.29. It still experiences the hang-up occasionally. Other than that I have not experienced any bugs. With that caveat in mind if you want a copy just e-mail me directly and I'll send the zip file to you. k2mk at comcast dot net 73, Mike K2MK Jim KS7S wrote I can't seem to find the latest beta firmware for the P3 - I downloaded the 1.21/1.34 version (NB on SVGA) but didn't download the 1.22/1.35 version when it came out. I don't see it in the P3/beta firmware directory now - what happened or what am I doing wrong?

Re: [Elecraft] Question K3 ALC w/SPE Expert 1.3K-FA amp
Just wonder, what is the reason for such a requirement? The requirement goes back to the 1970's and is designed to prevent amateur amplifiers from being used for unlicensed (freeband) operation with 5 Watt CB exciters. The intent was to match the gain needed to reach the US legal output power with the drive available from the typical exciter power level. For the Expert amplifiers to show 22 dB gain, they must be shipping without the attenuator or the distributor is removing the attenuators - both of which violate the type acceptance. On a deeper level, to design an amplifier with that much gain is bad design - part of the excess gains should be used for negative feedback to reduce IMD and improve stability. 73, ...

Re: [Elecraft] K3 Enhancement
In the Flex series, a second RX is a matter of more software and the memory and processor capacity to service it. Note that it's the high end Flex only that is in the neighborhood of K3 performance, and there is a reason for that which decidedly costs money. No cheap advantage just because it is software based. In my case I don't want the dependence on an operating system that sees transceiver internal operations as a micro micro micro niche in its target user population. The K3 functioning can't be undercut by a Microsoft OS or driver upgrade. At very least any Elecraft changes to their K3 proprietary code are aimed at improving things for K3 owners. If you want the Flex side of this discussion you need to be on the Flex reflector. 73 and good luck on your choices, Guy K2AV On Friday, April 3, 2015, Bruce Chadbourne ke...@arrl.net wrote: Greetings to the group.

Answer: This is possible using SDR software with an I/Q feed from the K3 IF. Check out the LP Pan unit and NaP3 SDR software. You will also need a suitable sound card with stereo inputs and outputs. This software creates two SDR receivers within the computer, which can then be fed to the computer's sound card for playback. You plug your headphones into the computer's sound card output. The better the sound card, the better this will work. The wider the bandwidth of the sound card, the greater the width of the spectrum you can display. The software is free. LP-PAN costs $250. The recommended ASUS USB sound card costs $65. http://www.telepostinc.com/P3_comp.html 73, Jim K9YC __ 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] April 1st belated
Actually Dick has not completed his QSO with me since he has not confirmed my signal report: RST = 0.0001, 5, 9 His 1kw CW signal with 20-dB gain to my planetary antenna with 35-dB gain on 20m resulted in SNR of -205.4 dB; I'm still integrating it to bring it out of the noise.

ARRL may initiate changing that law. Proud hams could drive that change. With current LDMOS devices lots of money can be saved with one stage amps.

I'm not bound to FCC rules and I'd rather prefer to drive such an amp with 1 or 3 watts from the KX3 to get 1 kW out than to cascade the transceiver with a driver amp and then a final amp.

Mode CW, VFO-A, nothing unusual. LEDs show Shift and Width functions enabled. When I rotate Shift, the vfo-b display simply shows FC *0.48 (my pitch, the center of the passband.) It does not shift. Width control works. I've power cycled, still no joy. No software connected, either. Pressing each button does nothing. (Should go to alternate mode, ie lo/hi cut. Long pressing shift does normalize. It's only the functions associated with the shift knob. What gives? What did I do wrong?

Re: [Elecraft] Question K3 ALC w/SPE Expert 1.3K-FA amp
On a deeper level, to design an amplifier with that much gain is bad design Huh? Why is that, Joe? We now have devices capable of 22 or even 30 dB of clean amplification. Why should we not use it? Just because FCC does not allow it in the U.S.? I'm not bound to FCC rules and I'd rather prefer to drive such an amp with 1 or 3 watts from the KX3 to get 1 kW out than to cascade the transceiver with a driver amp and then a final amp. Of course I'm just bound to German law which does not contain any stupid (pardon me, but it is!) amplification limits, just the maximum allowed power. How we generate it is up to us radio amateurs overhere. That also means responsibility, of course. :-) Happy Easter!

Re: [Elecraft] K3 Enhancement
I am.doing that exactly with a $250 afrdri SDR and an audio mixer panel. I don't miss my flex at all! And let me just tell you, you will not get K3 performance unless you buy a 6700 flex at almost double the cost of a k3 with sub Rx. I have been an avid flex user for 3 years but the K3 is far superior in a lot of ways. Listening fatigue, afx, filtering that is a brick wall, and quick tunability make the K3 a much better option for me. Don't get me started on operating system lockups. I am an IT consultant by profession with thousands and thousands of support hours under by belt, and even I have occasional problems. When my PC dies, or gets a reboot, my K3 is still going strong. That has tremendous value to me. One misfire in a major contest and you'll wish for the standalone K3. I know from experience! Joe PS. I think the Flex radios are awesome. I have nothing against them or their company and they have provided a tremendous resource for ham radio. I just think the K3 is a better value for the money.

Re: [Elecraft] Question K3 ALC w/SPE Expert 1.3K-FA amp
Oliver, We now have devices capable of 22 or even 30 dB of clean amplification. Why should we not use it? Many of the solid state devices that claim 22 dB or more of gain are *not* clean at maximum output. That 22 dB specification is based on saturated power output - often in *pulse* service. If the manufacturer actually bothers to provide full gain and IMD curves for the device you will quite often see the gain drops significantly at maximum drive and or maximum output power while the sweet spot for IMD is 2 to 3 dB *BELOW* rated (maximum) output for the devices in use. Using 3 dB of negative feedback, another 3 dB of fixed input padding and another 1 + 2 dB of switchable input attenuation to provide ALC in the event of overdrive uses the total gain of the devices in a much more intelligent way. The high degree of negative feedback and fixed input padding cause the exciter to see a very constant and resistive load permitting the exciter to operate at its cleanest. The negative feedback also greatly improves IMD generation/linearity in the devices and by keeping the devices typically below the 1 dB compression point further minimizes IMD. 100 W to 1500 W (US Legal limit) is only 11.7 dB ... 100 W to 2500 W (VE legal limit) is only 14.9 dB. The US type acceptance standard provides overhead in either case (if the amplifier is capable of 2500 W). I see no reason - unless one *wants* to generate the typical dirty Italian signal that one *needs* 22 or 30 dB of gain. Most QRP rigs are so dirty (worse in many cases than an IC-706) I would not want to see them driving a 1500 W amplifier in any case. 73, ...

Quote I am the proud new owner of a new K3. I am also the proud new owner of an SPE Expert 1.3K-FA solid state amp end of Quote! Please NOTE New Owner not The Owner of a NEW The Op was very CLEAR. JUDGEMENT was passed !

If the Amp was not bought from a local (USA) Commercial vendor, no harm was done. The op indicated he purchased the amplifier from (one of) the US distributors for SPE and that others who had purchased amplifiers from SPE through their US distribution channels reported the same high gain. Those amplifiers are *not legal for sale in the USA* - they do not meet the terms of their type acceptance. The rules also state that *nobody* is permitted to modify amplifiers *commercially* (e.g., a distributor for SPE) so that they are not compliant with the type acceptance. An individual amateur may make or modify *for his own* *use*, at most, *one* of a given model amplifier in any year. When it comes to playing by the rules, there is no Joe being Joe so back off. 73, ... Joe, W4TV On 2015-04-03 7:56 PM, Milverton M.

How we generate it is up to us radio amateurs overhere. It's not stupid when you become aware of the history. At one time there were no amplification limits. The problem wasn't with the amateur community. The problem was with the renegade CB community that was using the available high-gain amplifiers improperly and in violation of US law and with the manufacturers who were catering to them. The problems that were created became an enforcement nightmare consuming too much of the available enforcement resources. There had to be some technical limits that we could use as an enforcement benchmark on the manufacturing level before the devices got into the wrong hands. I don't know if the same problems existed in the European ham communities but it was overwhelming here. Disclaimer - I spent three decades on the FCC enforcement staff directing, inter alia, local CB enforcement including locating, shutting down, seizing, and forfeiting illegal CB equipment and assessing monetary forfeiture penalties to the operators, manufacturers, and dealer. I know that field quite well. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon __ 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 tnny...@yahoo.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 Message delivered to li...@subich.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 Message delivered to tnny...@yahoo.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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] Elecraft] KAT500 Feature Request
Sometime back, a FW update has the Tuner following as you tune. You don't have to tx. Put tuner into manual after training. 73, Fred K6DGW TDY Sparks NV Tom Blahovici tom...@videotron.ca wrote: Hi I think this is more or less in place now. If you put the tuner in manual mode, it will only tune if you press tune and then hold this setting. When you tune to a different location it automatically will load the existing tune settings. What I have done is a manual tune every 20 kHz or so and kept the tuner in manual. Thus it always locks the settings.

A Tap and Hold on the Tune button would lock the tuning solution in place. Then another Tap and Hold or moving the VFO would unlock it. This would be very effective at times.
