[Elecraft] Audio Output
I have a question related to the audio signal of the K2. I have completed the base K2 and during stage 2 I was already concerned about the low audio output. I first thought that my headphone was to blame, a 16 ohm unit that is not able to transfer all the audio power from the amplifier but now after completing stage 3 with the speaker installed I have a very meagre audio output. I'm not talking about loudness, I 'm talking about a low level audio signal of only a few millvolts at the standard 4 ohm speaker. This with AF and RFC fully clockwise. Further I disabled AGC and then it gets a little bit louder but if I use the speaker I can hardly hear, I have to use the headphone to hear . Is there any easy way to check the audio amplifier, I'm thinking to put a 1khz tone at the input of the LM386. Thanks for suggestions. K73 Arie KI6EWA __ Do You Yahoo!? Tired of spam? Yahoo!

Re: [Elecraft] Intermittent RXsensitivity...
Don W3FPR wrote Gerald, That certainly sounds like it might be hard to isolate. I may be wrong, but from the behavior it sounds like you have a relay with points that are not making good contact - when you put a bit of RF through it, it becomes OK for a while. Please be aware that this is just speculation on my part. You may have to work with it a lot to determine if it is really fixed. Intermittents are very difficult to troubleshoot. snip If you can induce the failure and then have it continue while you remove the heat sink, you could also check the relay points with a continuity test between the pins. Check the schematic key for the realy chart and the schematic itself for the appropriate relay points and pins. - Gerald, I agree with Don about a possible problem with relay contacts, I had a relay problem with my K2 some time ago which caused the receiver's sensitivity on 40m to decrease but which could be restored by either changing the band from 40m and back again, or transmitting a couple of dits. The cause of my problem was K1's contacts which switch in the 40m bandpass filter, specifically those of K1A. With all due respect to Don, making a continuity test might fool you unless the relay contacts have failed and are not just 'dirty', because the current from a DMM etc when reading low ohms might be enough to 'clean' a dirty contact just as a little bit of RF would, but certainly worth trying and would expose a more severe problem. If the problem is a 'dirty' contact sometimes the slightest vibration or movement of the rig / relay can 'cure' the problem - for a very short time. Since I am obliged to QRT for a several hours, please let me know if you would like to hear more. 73, Geoff GM4ESD ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] ROHS COMPLIANT?
If you know Wayne, you know he is a very environmentally responsible guy (Eric may be as well... we haven't talked about it). I can't imagine he would make that recommendation if it weren't absolutely necessary. With kits as complex as some of the Elecrafts are, there will inevitably be some rework to remove misplaced parts, not to mention the possibility of blown finals down the road, etc. Plus, there's the rework required to add options (you could buy the unpcbs that KI4GGX offers to minimize that problem... very inexpensive and convenient, http://www.unpcbs.com/). I plan to make the same stipulation to new builders of my kits, which are now shipping in RoHS compliant form, when I next update the manuals. 73, Larry N8LP www.telepostinc.com Dave Sergeant wrote: On 4 Sep 2006 at 4:02, Nick Waterman wrote: After trying lead-based and lead-free solder on some of the mini-kits, I went leaded for my K2 in the end.

Re: [Elecraft] K-2 and digital question
To the original poster who could not even receive. The RigBlaster is not used during receive. The audio goes straight from the K2 (I use the ext speaker jack) to the Line IN jack on your sound card. Until you can properly receive PSK, SSTV, RTTY, etc, there is no point in connecting up the RigBlaster. Once you have receive working, the instructions supplied for the K2 should work for transmitting but that will depend upon how you wired the microphone connector on your K2. Make sure you have the RigBlaster jumpered so that the signals appear on the same pins as they do on your microphone. The only problem I encountered was not being able to use the microphone through the RigBlaster due to hum on my audio. I suspect this is a grounding issue caused in part by not having the microphione jack in the K2 grounded in my version, S/N 2221. Next time I open it up for mods, it is my To Do list. 73, Mike WA3KYY At 07:55 PM 9/1/2006, Phil Kane wrote: On Wed, 30 Aug 2006 11:02:12 -0400, H.Cary III wrote: Has anyone connected a RigBlaster with their K2 for SSTV or PSK-31?

R: [Elecraft] ROHS COMPLIANT?
Well, I was considering the matter and I would like to add my two cents. Europe is becoming VERY conscious of the environmental problem, mostly because the environment-related arguments, especially if presented in a certain, emotional way are taking quick roots among the citizens, and that pays good dividends at the election day. As a matter of fact, I can point you the example of the total ban about hunting bucks, deer and wild boars in effect on the hills around my hometown. As a result, in a few years we got several people hospitalized because of wild boars, car crashes due to bucks, and a total devastation of the forest, since the bucks and wild boars have eaten all the gems and offshoots for five solid years in a row. Now, to the desperation of the greens, the local government has decided to start an emergency hunting effort, reducing the population by about 5000 wild boars and 1200 bucks in our county alone. What does it matters to the ROHS? Well, consider that in your car there are probably 30 grams of lead due to the Pcboards in your car stereo, and maybe 20 kilos of lead due to the battery. And if you buy an hybrid car, then you will have maybe 200 kilos of lead, cadmium, and what else you name in heavy metals; but thanks to the ROHS you will have been spared the 30 grams in your stereo Does that make sense?

The difference is that the lead in the batteries is very likely to be recycled, while the lead in the solder is not. There's so much lead in a battery, and it's so concentrated, that it's easy and economical to recover. The opposite is true for the solder. The whole lead-solder-in-electronics thing is due, ironically, to the relatively short life cycle of many electronic devices these days. I don't know about Europe, but here in the USA many people consider a 5 year old computer to be all but useless. I have found many completely working computers on the trash, discarded simply because they were old. Latest find was a 400 MHz PII Dell desktop, with 17 Dell monitor, 13 gb HD, 256 mb memory, Win2000, NIC, etc. Its next stop was the dumpster. How much lead is in that thing, I do not know. The ironic thing is that amateur radio equipment tends to have much longer useful life spans. Many 20-30+ year old ham rigs are perfectly usable today, particularly for non-critical applications. Even junked ham rigs are valuable for their parts, to restore others. btw, we have a similar problem with white-tail deer here. Back on New Years Day 2001 I bagged a doe on PA Route 202.

RE: [Elecraft] K2/100 10m SSB Distortion
Hello, What is the problem? My ssb-transmit has distortion on 10m. The other bands are ok. I have no mods on ksb2. k2/4781 73 de juha oh6os -- If it's on one band, it's usually RF getting into the audio circuits on that band, most commonly through the microphone connector. One other thing that could be a factor with the K2 is that on 10 meters the output is usually the lowest, so it's just possible that you're over-driving the rig with audio on that band to make full output. Are you using an external mic preamplifier? That's a common source of both RF feedback into the audio and for enough audio to over-drive the rig. Even if you have no audio preamplifier, the possibility of RF getting into the mic is the first thing to check. The easiest way to do that is to switch from your antenna to a good dummy load and compare your audio on a monitor receiver.

[Elecraft] ROHS COMPLIANT? Do you really care?
Hi all I think the RoHS issue has been flogged as much as it can be. I also think Elecrafts position is being confused a bit (as I understand it anyway). As far as I can see there is no claim that the kits are RoHS compliant. This blossomed from the price increase thread where I believe Elecraft mentioned they were buying RoHS compliant parts which are costing more but they had to do it as they were mainstream available and leaded parts were becoming harder to find. There is no coc, no documentation and no audit trail claiming RoHS compliance, so regardless of the dialogue here, due diligence has not been observed at any level therfor the importer will be liable for non conformance (the EU importer, NOT Elecraft) if applicable. Not sure what Elecraft will do for PCB finish but I would guess rather than switch to ENIG or similar the plating will still be Sn/Pb HASL as the preferred solder alloy is still going to contain lead. So forget the parts. The SSB adapter board I have here with DC 23/06 says RoHS on it but the plating looks like HASL SnPb to me (not compliant) and if it is just a pure tin finish (Pb Free) then it makes no sense for Elecraft to say Pb Free solders void warranty as SAC305 alloys in Kester or Multicore will flow just as easy when fluxed. For rework some drill hole apertures will need to be enlarged and if the PCB material is sub standard you risk lifting some lands due to the slightly higher temperatures involved when applying the iron or desoldering tool. As long as a single component inside the box is not compliant (remember that also includes any plastics and plated metals) then forget about it. Assemble with SnPb solder, forget about it. All roads to non compliance. The only issue not fully investigated is if the kits actually have to conform, as a finished product placed on the EU market commercially, yes they do, regardless of country of origin. EU manufacturers are responsible for the audit trail and compliance measures (usually wrapped up inside a formal QC system) but anyone importing parts or products into the EU (parts) to be placed on the market not only take responsibility for their own actions, but those of the external EU manufacturer also. Regulations vary country to country, they are not uniform across the EU as their enforcement methods are different, but the term due diligence is used quite a bit and to demonstrate its execution is not so easy, is the part compliant?, yes, how do you know?, the suppliers says so, can the supplier be trusted? Does the supplier have lot traceability back to the factory? How was the materials tested? Which method was used...are there certified lab results.. You would hate to see the flowchart / decision tree out of our QC system at work We also had to drop any suppliers unable to meet the audit trail requirements as well as scrap / remove from site all non compliant inventory as contamination of complaint stock was also a risk. That's risk assessment at its best. It is really a big can of worms to open. It kind of takes the fun out of the whole building deal I can tell you! A few hours of working the front panel of the K2 and using the mic helps put the fun back in it for a while :-) John ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] K-2 and digital question
Phil and all, The Rigblaster is capable of controlling PTT from its serial port connection. I don't have a RigBlaster, but I just looked at the schematic and see that you must have P5 pin 1 jumpered to pin 10 (PSK31 programs control PTT with the RTS signal), and you must jumper P1:B pin 18 to whichever pin you use on your K2 mic jack for PTT (if your K2 is wired for the Elecraft configuration with mic pin 2 as PTT, you would wire P1:B pin 18 to P1:B pin 25). That should allow the RS-232 interface, the Foot switch as well as the front panel mic input to control the PTT line. Of course, the AUTO/VOX switch should be in the AUTO position. I don't know how that squares with the Rigblaster instructions, but it is what their website schematic indicates must be done. After looking at the Rigblaster schematic, I am amazed that they did not include a transformer in the headphone jack to soundcard connection. What that means is that despite all the optoisolators used in this unit, the headphone jack connection negates any other attempts to isolate the computer ground from the transceiver ground. Now I realize there is yet another reason for all the hum and noise complaints about the audio when the Rigblaster is used. I would strongly suggest modifying the RigBlaster by adding a transformer to break this sneak ground path - if that is possible in this unit (it may not be due to the physical ground arrangement). 73, Don W3FPR -Original Message- On Mon, 04 Sep 2006 10:12:47 -0400, Michael E. Dobson wrote: Once you have receive working, the instructions supplied for the K2 should work for transmitting but that will depend upon how you wired the microphone connector on your K2. Make sure you have the RigBlaster jumpered so that the signals appear on the same pins as they do on your microphone. I have the RigBlaster connected to one computer serial port and the K2 connected to another for remote control via Ham Radio Deluxe. The main question I have is if there is a better way to get the computer to trigger the transmiter than to use the VOX. The only problem I encountered was not being able to use the microphone through the RigBlaster due to hum on my audio. I suspect this is a grounding issue caused in part by not having the microphione jack in the K2 grounded in my version, S/N 2221. Next time I open it up for mods, it is my To Do list. I have a much later K2 and have had no reports about hum. -- 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Low Audio Output of K2
I have a question related to the audio signal of the K2. I have completed the base K2 and during stage 2 I was already concerned about the low audio output. I first thought that my headphone was to blame, a 16 ohm unit that is not able to transfer all the audio power from the amplifier but now after completing stage 3 with the speaker installed I have a very meagre audio output. I'm not talking about loudness, I 'm talking about a low level audio signal of only a few millvolts at the standard 4 ohm speaker. This with AF and RFC fully clockwise. Further I disabled AGC and then it gets a little bit louder but if I use the speaker I can hardly hear, I have to use the headphone to hear . Is there any easy way to check the audio amplifier, I'm thinking to put a 1khz tone at the input of the LM386. Thanks for suggestions. K73 Arie KI6EWA __ Do You Yahoo!? Tired of spam? Yahoo!
