John - I'm sure everyone will have a different opinion.and if you include
"rigs of the past", then what was once good really may not be comparable to today's radios.but radios that I have enjoyed using in the past - that I thought were good performers at the time I owned them -- include Signal/One CX7B, Kenwood TS-930S, Kenwood TS-950SD, and Yaesu FT-1000D. I now have a K3 (actually two) and still have the FT-1000D which I still enjoy using occasionally. Most disappointing radio I have owned - a Signal/One CX-11A. It was supposed to be the "be all, end all". It wasn't. I'll be curious to see what others have to say. 73 de Greg-N4CC _____ From: John Merrill [mailto:[hidden email]] Sent: Saturday, January 30, 2010 9:40 PM To: Elecraft_K3 Subject: Re: [Elecraft_K3] Re: K3 comparison to TT Omni VII If the K3 is the best rig, what would be the second best including any of the past?

Like you just said,everyone will have a different opinion but mine is that the second best rig which is very close to our K3's in performance is the Tentec Orion II that I owned as well in the past and sold because of been too big on the desk.

[Elecraft_K3] TX CW discrepancy
|
|
It has started with complains of some of our contacts in the contest. They
told us that the weighting of out TX CW is not standard. Two channel oscilloscope was brought into shack and 3 K3 tcvrs were checked: SN 1651 SW ver 3.06 SN 2929 SW ver 3.68 SN 3553 SW ver. 3.41 On all 3 units series of dots were sent using external keyer with 50% weight. While on the monitor output the weight remained to be 50% the RF output showed shortening of dots (and therefore lengthening of spaces) by 7 or 8 msec. This effect does not depend on WPM speed and therefore less pronounced at slower speeds. Could somebody confirm this please. We do not want to trouble Elecraft without being 100% sure that the problem exists. 73, Igor UA9CDC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |
Re: [Elecraft_K3] TX CW discrepancy

What I have noticed is that K3 internal keyer weight changes between VOX and
use of footswitch. I tend to press footswitch time to time to prevent amplifier relay sound ( AL1200 relay is loud ) but noticed this bit annoying feature after trying K3 internal keyer instead of microkeyer. The weight change is roughly from 1.10 to 1.20 ( from Vox to Footswitch ) Olli OH6CT > -----Alkuperäinen viesti----- > Lähettäjä: [hidden email] > [mailto:[hidden email]] Puolesta Igor Sokolov > Lähetetty: 31. tammikuuta 2010 16:49 > Vastaanottaja: [hidden email] > Kopio: [hidden email] > Aihe: [Elecraft] [Elecraft_K3] TX CW discrepancy > > It has started with complains of some of our contacts in the > contest.

Igor, before I did anything else I would have a good friend whose judgment you trust listen to the Morse you generate with a critical ear and give you an honest opinion. Preferably someone who can hear you quite well and on a clear band. Contest comments can be accurate with the best of good will and they can be made with malice by someone who does not wish you well.

The effect of so-called "dit shortening" becomes more noticeable at higher keying speeds since the amount of rise-time truncation remains fixed for all keyed elements, regardless of keying speed. Igor, were you using PTT CW keying? PTT CW from a contest card results in perfect timing by the K3. In that mode, RF is generated only 3 ms after external key closure and RF keyed element length exactly matches the dry contact closure time. If you were using an external keyer without PTT activation, then you may want to experiment with the NEW and OLD QSK settings. The NEW QSK mode appears to truncate keyed elements to a greater degree than the OLD QSK mode. I see no timing differences between full QSK and Semi-QSK. In OLD QSK, my K3 truncates keyed elements by only 3 ms. That amount is made up by adding 3 ms of compensation with a microHam keyer. With the K3's TX DLY set for the default 8 ms and QSK set for OLD, the total CW delay time from external key closure to the start of the RF envelope is 15 ms. The NEW QSK setting adds further delay of ~ 4 ms for a total delay of 19 ms. However, the added delay is not made up at the end of the envelope and the NEW setting will start sounding choppy sooner than the OLD setting. By the way, the TX DLY setting is meant to control the timing of an external amplifier from the KEY OUT jack until first RF appears in 1 ms steps. But, others have found (myself included), that TX DLY also has an effect on the keyed element duration, particularly the first dit or dah.

I think in at least one case it is 20ms but why > should it affect anything in a series of dots sent with PTT permanently > enabled? I'm not near my radio to try it, but try setting it to NOR 08 and see if the problem goes away. I know it is intended for QSK, but it does delay the onset of RF so it may shorten the keyed elements even if you are using ptt. -- 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:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

What it is doing is waiting after key closure to start generating RF. The fact that you are not using the vox/qsk to initiate closure of the amp key circuit doesn't matter. -- 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:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |
