Re: [Elecraft] K2 and SSB
Good evening to all, the problem is fixed by the memorandum of K2, I have not managed to valid the PC and spectrogram, I know it's going to laugh ... Now I get properly LSB / USB and all the filters are OK thank you to all who help me 73 , Christophe F8ACF - K2 # 7369 De : Don Wilhelm À : Ralf Wilhelm Cc : Christophe F8ACF-56 ; "elecraft@mailman.qth.net" Envoyé le : Lundi 20 mai 2013 19h59 Objet : Re: [Elecraft] K2 and SSB Ralf and Christophe, Yes, what you say is true, but the answer is still in the filter alignment. All the SSB filters should be aligned - AND - in many (most) K2s built in the last several years, the suggested settings for the SSB filters other than the OP1 BFOs do not work well. That is because the varactors have changed (the type has not changed, but the capacity range has increased - blame the manufacturer!). The result of this varactor variation is that the filter width displayed by the K2 is usually much more narrow than the actual width (not true for the OP1 filter which has no varactors). I do not know of any way to easily find the actual width of the filter other than using an audio spectrum analyzer like Spectrogram. 73, Don W3FPR On 5/20/2013 1:25 PM, Ralf Wilhelm wrote: > Hi, Christophe and Don, > > There is a point I don't understand: The K2 switches to "VFO below rx > frequency" on 15 and above (main manual page 85) thus resulting in sideband > "inversion".

Re: [Elecraft] K2 and SSB
Don, OK, didn't know that... I have to admit I didn't build my K2 myself but bought a used one. The guy who sold it to me actually has done what is described on your page, the rig was delivered with some kind of "test protocol" that includes a "filter response" measured with your approach. Germany's QST equivalent "cq DL" also described this method a few months ago, I think the author was the "official" german Elecraft importer DL2FI...

Re: [Elecraft] K2 and SSB
Hi, Christophe and Don, There is a point I don't understand: The K2 switches to "VFO below rx frequency" on 15 and above (main manual page 85) thus resulting in sideband "inversion". So, if Christophe can receive USB on 15, shouldn't that mean that the BFO is properly set for LSB reception on 17 and below? If he can also receive USB on 20, shouldn't that mean that both BFO settings are ok?

Re: [Elecraft] K2 and SSB
I'm no expert in assembling the K2, but, in RX, the SSB option only uses the additional xtal filter. If SSB sounds like SSB received on AM, my guess would be that the BFO (RF board) is not oscillating. Maybe pulling the crystal to far makes it instable. Is it on both sidebands? Since the K2 switches from a "oscillator above rx frequency scheme" to a "oscillator below rx frequency scheme" somewhere, there are possibly bands where USB doesn't work but LSB does work and reverse.

On Jun 12, 2007, at 2:49 PM, Gary D Krause wrote: The reason I am asking is because, I have the SSB board ready to install. I have been using the basic K2 the last few days in CW mode and I really like it since I work mostly CW. The installation of the KSB2 won't affect operation on CW. If anything, you'll be able to use the wide OP1 filter on CW as well. I have a Kenwood TS-530SP that works great on SSB so, I'm trying to decide if it's really worth installing the SSB option. So, I'm trying to gather as many opinions as possible so that I can sit and torture myself further. :-) Go for it. I've been using the KSB2 for five years now. It works pretty well. I've got an unusual K2 because I have changed the capacitors out for the "1.9" kHz filter design by KI6WX. Current KSB2s use a bit wider filter selection. I did own an Argonaut V for about eight months. It would put out about 20 watts which made SSB a bit more of a challenge. Since I have the Kenwood that will put out 170 watts, believe it or not, I'm thinking that I would probably not use the SSB option unless it's for QRP SSB. I think it would be pretty near impossible to get 170 watts OUT of a TS-530SP. The rig used a pair of 6146B tubes. These are good for about 90 watts INPUT EACH, for about 100 watts out, perhaps 80 watts on 10m. Your opinions are welcome. I should mention that I'm not planning to add the 100 watt amp to the K2. If I'm going to do that, I'll just buy a K3! I also work a lot of QRP CW. The 100 watt amp can be deactivated just by turning the power knob down. The K2/100 is still a great radio. The KAP100 is only what $389? A K3/100 is more than four times as much.

RE: [Elecraft] K2 and SSB
There's a small but significant advantage to staying with the "standard" Elecraft OPT1 filter bandpass, rather than using one of the wider bandpasses you can achieve with the optional capacitor kit. The narrower bandwidth helps the S/N radio. The less bandwidth the 5 watts occupies, the "louder" it'll be at the receiving end. Ron AC7AC -Original Message- Okay, I've decided to install the SSB option. After all, I paid for it so I might as well use it. I have a Kenwood MC-60A mic that I'm going to use with it.

Re: [Elecraft] K2 and SSB
> I was just wondering how many here use SSB with their 15 watt K2? Does it > meet your expectations? Hi Gary. I put my K2 on the air (SSB) and made a number of contacts on 20 and 80 meters before even opening the KPA100 parts box. If I didn't tell people I was running only 15 watts at the time, I don't think many of them would have known. :-) There are just s many variables involved in propagation that under many circumstances, a 10 dB signal deficit may not be as drastic as one might think. 73, de John, KD2BD Visit John on the Web at: http://kd2bd.ham.org/ . . . .

Re: [Elecraft] K2 and SSB
Okay, I've decided to install the SSB option. After all, I paid for it so I might as well use it. I have a Kenwood MC-60A mic that I'm going to use with it. I hope to work some of you guys on the air. Thanks for all of your input.

RE: [Elecraft] K2 and SSB

Re: [Elecraft] K2 and SSB
Gary, QRP SSB contacts can be plentiful, so just put the SSB option in - you can also run soundcard digital modes if you want. I usually stay away from the 80 meter roundtables where everyone is bragging about how much power they are running - you will just not move their S-meters up into the 40 over mark and those folks will frown on anyone who does not do that. 73, Don W3FPR Gary D Krause wrote: I was just wondering how many here use SSB with their 15 watt K2?

Re: [Elecraft] K2 and SSB
Gary the K2 works nifty on SSB, either as a 15 or 100 watt radio. even with only a vertical I would not hesitate to call someone DX on 20m. of course its easier when sunspots are higher! i have made many contest QSO's running SSB QRP. and this is a great rig for running PSK31. so if you have the board go ahead and install it! count the dB's carefully and convert them to the number of S-units. i am not saying don't QRO, as when i discovered working DX on 80m CW is interesting I added 100w to my K2. i won't debate the K2 vs. K3 trade! converted to $ per dB of performance, i am not sure where this will fall. 73, curt --- Gary D Krause <[EMAIL PROTECTED]> wrote: > I was just wondering how many here use SSB with > their 15 watt K2?

RE: [Elecraft] K2 and SSB
I found SSB at 10 watts to be a challenge. I run mostly CW and didn't want to work at the few SSB contacts I make per year. At the same time I compared the K2's receiver with my 830s and found the K2 to be much nicer so I sold the 830s and put in the 100 watt PA. Then I went back to CW. I haven't had the mic hooked up since I did my first post-build testing. - Keith N1AS - - K2 5411.ssb.100 - -Original Message- From: Gary D Krause I was just wondering how many here use SSB with their 15 watt K2?
