Re: [Elecraft] has the k2 a future?
There's no issue with program memory in the K2; we could upgrade to a larger part. But we spent years on K2 firmware and optimized it for the rig's intended usage, and it's a business decision to focus on other products for the time being. 73, Wayne N6KR On Oct 15, 2009, at 2:41 PM, David Woolley (E.L) wrote: Mike Harris wrote: I understand from a previous post that memory is maxed out __ 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] has the k2 a future?
Hi Geoff I would think that the phase noise limitations of the K2's design would limit its appeal. I would be more interested in a K3-Junior Maybe this K3 junior would have a single receiver Inbuilt power supply 200 watts 50 volt or higher fets Layout like Yaesu FT950 VFD display - blue external TXCO input A real analog S-meter Front firing speaker A big 10 watt audio PA Amplifier tuning pulser(audio) 2 tone generator controls on the front panel Built in directional coupler for TX monitoring Optional control port for a DSP receiver like QS1R(or even a Elecraft version of the QSR1) A high performance tuner like the SGC230 SO2R interface built in for 2 X K3 JNR's USB interface Ability to select and key 2 amplifiers with different drive power levels In built dummy load NTIA specifications for the TX PA that can work into a 3:1 VSWR load Blue tooth headset support Anyway its a nice dream, however this radio would be the best selling radio in the world I would think. It would certainly make the new Hilberling look like very poor value for money I would buy 2 or even 4!

Re: [Elecraft] has the k2 a future?
Any transceiver can be improved. But working on the K2 again... Elecraft would have to make a business case first and then decide. Anyway, my K2 is just fine as it is, and it's on duty for the next few weeks as one of the transceivers in the TY1MS dx-pedition. I already worked them with my K3 :-) 73 Arie PA3A -Oorspronkelijk bericht- Van: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] Namens Geoffrey Mackenzie-Kennedy Verzonden: woensdag 14 oktober 2009 10:57 Aan: Wayne Burdick CC: Elecraft Discussion List Onderwerp: Re: [Elecraft] has the k2 a future?

Re: [Elecraft] has the k2 a future?
I am not certain where that statement about phase noise comes from, nor if it is valid. The K2 comes in at -123 dBc (or -124 dBc) in the phase noise category. The transceiver comparison list at the Elecraft website does list phase noise as measured by ARRL and by Sherwood. I did a quick count - There are only 5 listings that have phase noise measurements better than the K2 (one was the K3), and 19 ranked worse than the K2. I don't have phase noise measurement capability here, so I must depend on the ARRL and Sherwood test data, but those measurements are well respected by most hams. The Sherwood list is more extensive, and lists LO noise. In the 27 transceivers at the top of the list, there were 16 better than the K2, 3 equal to it, and 8 listed worse - so IMHO, the K2 is a bit below average within the top 27 listings - not too shabby for a 10+ year old design. 73, Don W3FPR juergen piezo wrote: I would think that the phase noise limitations of the K2's design would limit its appeal. snip __ 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] has the k2 a future?
Wayne, any hope of firmware updates for the K2? My favorite would be keeping mode and ATU setting per VFO.

This past weekend two of us went to a undisclosed location in the Sierras to check out our FD QTH for next year. Although I wouldn't give up my K3 for anything, there is no comparison to the K2 for this application. The combination of QRP-configured K2 plus Asus netbook was tested last year in a not-so-great location, but we ran the whole period on batteries and solar panel. The K2 is by far the winner if you are looking for high performance with low power consumption. By the way, the secret location is a killer. With 15 watts to a 40 meter loop with apex at 30', our first QSO was a 5N (Nigeria). That's on 40 meters at 4 PM local time! And our antennas are going to be much, much better. -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco __ 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
