Re: [Elecraft] K3 CW Text Decoding
Ed, It seems to make little to no difference what operating system you use. CW Skimmer will never out perform your ears for weak signals; I don't think it was ever designed for weak signals. But, for most every other CW signal that is reasonably sent, it does seem to work well. And, to me it seems to work better when using I data vice just the audio out of the radio. This just may be the sound card I was using at the time. I just haven't done the in depth testing; I do admit it would some interesting testing. I'm presently using LP-Pan and a Steinberg UR22 running at 196KHz sampling rate with my receiver usually set to around 250-300 Hz while contesting. I do suspect that the A/D will make a difference and my external sound card should be superior to my internal one. What I do know is that Skimmer uses a statistical approach vice just sampling, and in a contest when I'm tired, it does better than I do. Do keep us up with whatever you find. 73, Barry K3NDM -- Original Message -- From: "Edward R Cole" To: "Elecraft Reflector" Sent: 10/9/2019 2:43:58 PM Subject: Re: [Elecraft] K3 CW Text Decoding Barry, I had CW skimmer installed on my old winXP computer but was not impressed with CW detection of weak CW (same for the K3).

Re: [Elecraft] Blasphemy maybe but looking for an honest assessment of the K2 vs. Icom 7300 ...
Randy, I have just added a Clifton Labs Z10 buffer amp to tap the IF on the K2. I intend to feed to an RSP1 so I can have a panandapter. This buffer amp is something that I've had for years. Jack Clifford passed away several years ago, so I believe it is now available through DX engineering. So, you could have a band scope, but you wouldn't be able to QSY by touching the signal on the screen, like the 7300 (and other new radios) can. If you could live with 50W, the Tokyo Hi-Power HL45B (or HL-50B), and the Hardrock 50 amps come up for sale used on QRZ.com quite often, sometimes in the $250-$400 range. One of those, and a used LDG antenna tuner for ~$125.00 might be a cheaper way to use the K2. However, a 7300 would certainly be an easier, turn-key solution. I love my K2/100, and it gives me a lot of pleasure operating it, and knowing that I built it. BTW, I have a spare, unused E850138 "Temp Compensated PLL Reference Upgrade" kit. If you decide to upgrade the K2, I'll send it to you for $15.00. Good luck. 73, Jim KO5V __ 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] Blasphemy maybe but looking for an honest assessment of the K2 vs. Icom 7300 ...
Randy - My situation is not dissimilar to yours, as I was licensed in the '60s, inactive for an extended period, and became fully active again just a couple years ago. At that time, the IC-7300 seemed like the ideal rig for me, and I have not been disappointed. In fact, I now own two of them. Interfacing with a PC is as seamless as you can get, and requires only a proper USB cable and installation of the correct driver for it. I operate in all digital modes as well as conventional analog modes. The 7300's menu system allows fine tuning of all the relevant options, and the settings can be saved to an SD card for immediate retrieval ... which makes mode changing very fast. I was also "HOA challenged" until I was elected to the HOA board and managed to get the rules changed. I operated for nearly two years on a modified G5RV Jr in an inverted V configuration in the attic. I used the Icom AH-4 tuner connected to the 450 ohm feedline in the attic and the results were nothing short of fantastic, considering all the handicaps. I literally had no problem matching any frequency from 160 thru 6 meters (a subsequent MARS modification to the 7300 also gave me very narrow 630m coverage). If you are planning any kind of balanced or unbalanced wire antenna, as long as it is at least 24 feet long, I would highly recommend the same. While I have no firsthand experience with LDG tuners, I have spoken with several users who have had bad experiences with the IT-100. I also used my AH-4 with a 360 foot EDZ for a period of months with even better results, but changed to the KAT500 this Summer in order to accommodate more power (KPA500). While the KAT500 is great for what it does, I really miss the performance the AH-4 offered at low power. Incidentally, the KPA/KAT500 combination also works seamlessly with the 7300. It's the best of both worlds, and kudos to the Elecraft engineers for making a fine product that "plays well" with non-Elecraft products. 73 Lyn, WØLEN -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Randy Heise Sent: Tuesday, October 08, 2019 10:59 PM To: Elecraft@mailman.qth.net Subject: [Elecraft] Blasphemy maybe but looking for an honest assessment of the K2 vs. Icom 7300 ...

Re: [Elecraft] Blasphemy maybe but looking for an honest assessment of the K2 vs. Icom 7300 ...
Randy, You pose an interesting question. The 7300 has been *extremely* popular for the amount of features it delivers for the price. If you go that route you can sell the Signalink. However I'm not sure you would see much difference in receiver performance. Another thought is a used K3 with a built-in tuner. There are a lot of them on the market now that the K4 is almost being delivered. If FT8 is your only interest I'd suggest the 7300. -de John NI0K Randy Heise wrote on 10/8/2019 10:58 PM: So, background!

[Elecraft] K3 and VHF/UHF add-ons
[Note - slight twist on the subject line] As to using the K3 for VHF/UHF work, I recently tried to configure a K3 with just the UHF band on it - all of the HF bands mapped out because the unit doesn't have a HF antenna connected and it would avoid operator mistakes. So, just one of the TRN bands configured and only having that band in the band map, all the regular HF bands disabled using CONFIG:BND MAP This, however, triggers a firmware bug on the K3 with latest firmware (5.67): the BAND switch will switch to either 80m or 10m, depending on whether I press the DOWN or UP button. And that is with the 80m and 10m band disabled. This has been called in though channels and it's not the end of the world but there doesn't seem to have been a release, not even beta, since January. I hope Elecraft will find the cycles to make what seems to be a trivial fix. BTW, I did find it beneficial to configure the K3 to display 89 MHz instead of 10489 MHz. This way, the frequency digits don't jump around when you switch from COARSE to FINE. 73, Geert Jan __ 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

I think the 590 is a better radio than the 7300, for about the same $. I love the K2, but the 590 (or 7300) is a better radio for general Digitial mode use, and either will give you a band scope. The 590/RSP1 combination will give you a band scope on the computer that you can use to click on and move the tuning, everything on one screen with a keyboard and mouse! There are many Utube videos on the 590/rsp1 bandscope combination. Gordon - N1MGO On 10/8/2019 23:19 PM, Randy Heise wrote: So, background!

I don't know, Don. If he installs the KPA100 the lack of temperature stability will be a serious issue, at least for digital modes. My experience was that before installing the temperature compensation mod, the drift was unacceptable even on CW. This was not a problem before the additional heat generated by the KPA100. I think what he should do is get a newer rig (I won't speculate as to what's best) for his home-based digital operations. Then he can either keep his QRP K2 for portable fun, use it as a backup rig as I have done, or even sell it (as I would NEVER do!) 73, Victor, 4X6GP Rehovot, Israel Formerly K2VCO CWops no. 5 http://www.qsl.net/k2vco/ On 09/10/2019 7:32, Don Wilhelm wrote: Randy, Faced with that kind of decision (mainly dollar comparison), why fully upgrade the K2 with the A/B mods -- just update the firmware to get the added functions. From your question, I surmise you are not necessarily 'in love' with your K2 as some of the original builders would be having tremendous pride in the fact that they built it themselves. I for one have my Field Test K2 SN 0020 which has been fully upgraded, but I will not part with it - that is for my heirs to decide. Yes, you will not have the temperature stability of a new K2, and you will not have some of the other K2 hardware improvements. But it will still work fine for less money than a full upgrade. I am assuming you will be using it in a temperature stable environment. Any K2 can work great - the most important for receive performance is the IF filter alignment, so do that carefully with an audio spectrum analyzer running on your computer. If you are planning digital modes, turn on the RTTY filter set and align those filters to optimize your digital filters while not disturbing your SSB settings, especially compression settings. I am certain the Icom 7300 will have more modern features, but in receive performance even the oldest K2 can stand on its own. I have not compared the K2 with a 7300, but you can check the Sherwood ratings to see the relative ranking. Oh yes, if it is a QRP K2, and you want 100 watt capability, you will need the KPA100 and KAT100 as well. There are parts in the KPA100 kit to upgrade the 10/12 meter bandpass filter and the VFO ALC. 73, Don W3FPR On 10/8/2019 11:19 PM, Randy Heise wrote: So, background!
