Hi Paolo, You wrote :- 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. You are correct. I have seen people wearing gold rings and body-piercing metal stuff while protesting about mining. The same people complain about lack of communication during emergencies, and make submissions to local and Central Government to prohibit any antennas in urban areas. Don't worry about them - they are not on this list - just remember their names when they need you and your K2 in an emergency..G 73 Ken ZL1AIH ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Re: RoHS
It's not just a matter of using different solder. The new solders have a higher melting point and hence need a hotter soldering iron; typical 50W WECP/WTCP won't do because, while they have the temperature, they lack capacity at those high temperature - they can't heat the joint quickly enough. You'll need the newer 80W soldering stations or risk cold joints. There's a reason the older 50W stations are available so cheaply these days. The new soldering iron comes with a tip that has a thicker ironized coat as the new solders corrode tips a lot faster. Forget about using a wet sponge. Because of the higher temperature, wiping on a wet sponge would cause too big a temperature jump and hence you'll need to wipe on a special tool. Note that the routine differs: wipe, wet, solder, wipe, wet, back to holder. The new tools together cost about half a K2. Note that it's important not to contaminate your RoHS-tools with your older tools: small pieces of lead will change the composition of the alloy, greatly reducing reliability. The higher melting temperature means that un-doing a component is more difficult, with a higher chance of PCB damage, certainly with less experienced builders (not everyone has a space qualification, I don't). Because the new solder's wetting characteristics are a lot worse, I'm concerned about stripping and wetting toroids with lead-free solder. Wel all know that not everybody is fully successful wetting and stripping toroids as-is. Just ask Gary, who, I'm sure, is not looking forward to higher warranty claim percentages because of doubtful toroid stripping with lead-free solders. Note that some new alloys have a tendency to form bridges (shorts) after a number of years. Not a problem for a toy that gets discarded after 2 years, but big problem for a tranceiver which typically has a lifetime of 20-30 years. We all see the cheerful messages from people who haven't soldered in over 20 years or so, and are now getting back to kitting. Lead-free soldering is a lot less forgiving to new, but unexperienced builders as it is intended to be used in tightly controlled circumstances. (we all know that with a WTCP and leaded solder it's difficult to go wrong). While I realize that it's less environmentally friendly, I think that using leaded solder, for a large percentage of the building population, will have enough advantages that we should make use of the exception to the rules that was given to us kit-ters. I agree with Elecraft that the change should not be made lightly, and not just by using different solder. They suffer the consequences of a lower yield percentage, and I don't think anyone would want that. 73, Geert Jan PE1HZG K2#1981, not RoHS-compliant, sorry! ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] DMM Recommendation
I needed (wanted) a new DMM a few months ago. Initially was leaning toward Fluke but didn't want to spend the money. I ended up buying an Extech off e-bay. It in the Mouser catalog for $200+. I got mine for about $90 or so, new in the box. I think it was a discontinued model as the seller had more than one. The meter does cap and freq measurements as well as V-O-A. It seems to work OK although it is not that fast in auto mode. I also find the backlight feature gives uneven lighting but it's better than nothing.

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), It is shipped with this jumper on only one pin in the default condition. I put it on both - didn't even have to scrounge my jubk box for the jumper! 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). This is done when one sets up the mike configuration in the RB. 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. One other item needs to be noted. In MixW (for those of us who use it), go to Config | TRCVR CAT/PTT and make sure that the serial port used for the RB is specified and enabled and CAT set to None. When all that was done, everything worked properly. I don't know how that squares with the Rigblaster instructions, but it is what their website schematic indicates must be done. It's in there on the last page but it's rather cryptic. The configuration is the one for PTT on RTS DTR and TXD on KEY 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). Hmm g I don't think that it's possible because of the way the PCB is laid out. Perhaps the designer for West Mountain Radio could take that into consideration. My RB is fed to the computer through an iMic USB adapter. I don't know if there's any isolation in that, or if an in-line isolation transformer outboard of the RB would do any good. In any event I don't use the headphone jack on the RB.

[Elecraft] Re: ROHS Compliant/Lead Solder
Seems to be time to GIVE IT A REST. No one is going to solve the ROHS world, or the MIL SPEC world, of the METRIC for U.S. world either. These things come and go. When they figure out how to remove the LEAD/ACID battery from all of our millions of automobiles - then I'll start to be concerned. How about the lead balancing weights on your tires? Lead sinkers? Lead bullets in Iraq and Tazmania? Lead battery terminals? ... Leaded windows in our churches? Linotype lead in those old european russian printing plants? Fred FL __ Do You Yahoo!? Tired of spam?

[Elecraft] K2/100 10m SSB Distortion
Tnx for reply Ron I tested with dummy load and no difference! I took away kpa100 and running qrp, it sounds very good on all band, even on 10m and more than 10 watts. But with kpa100 and full output there is disdortion on 10m. I noted I have made Grounding of mic jack and RF filter on input of compressor mods. No KI6WX mods. 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. Ron AC7AC 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 -- ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
