[Elecraft] Soldering stations
Support Don's advice - I have also been pleased with the "Solomon" soldering station. Built my K2 3314 with the UK badged digital version, the SL-30 from Vann Draper, which reads in Celsius over here. Understand it is just the same inside as the led version. Has a neat set/read switch and is properly earthed; has a good range of bits, too. 73 Rob M0RAC Robert A Cochrane 7 Lawn Terrace Blackheath London SE3 9LJ UK Tel (44) 020 8297 1978 Mob (44) 07764 197 701 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] OT: Demagnetize Soldering Tip?
Hello elecrafters, recently I worked on my hifi-speakers, I had to replace the bass-speaker. I somehow must have magnetized the soldering tip, it will not stop heating. In fact, it becomes glowing red! What can I do to demagnetize it? Do I have to replace the tip? It is a Weller WTCP-S, it has a magnetic tip to control heat. -- Best regards, Martin K2 #2706 mailto:[EMAIL PROTECTED] ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] OT: Demagnetize Soldering Tip?
Hi Martin, The Weller TCP soldering iron uses a magnetically operated switch in the centre of the soldering iron. The soldering iron tip has a cap on the inner edge of specific magnetic attraction properties that is neutralised by what I believe is called the "Curie point effect" when this cap reaches a critical temperature. This releases the switch actuator and cutting off the 24V feed to the soldering iron heater. You may have to replace the TCP switch assembly, though it would seem that a permanently magnetised tip may be the cause. Try another soldering iron tip first as the actuator switch assembly is rather more difficult to replace. If the tip is the cause it may be possible to demagnetise it with a TV picture tube degaussing wand. A message to all to keep the TCP iron away from speaker magnets, particularly the Hi-Fi kind.

[Elecraft] Soldering stations.
Ron, I think you responded to the wrong message (about the KX1). :^) Weller also has soldering stations with an adjustable temperature control. I have used the WTCP type with fixed-temperature tips but prefer the adjustable model WES50 which I used to build my K2. This model has been replaced by the WES51, which is probably a bit more expensive than the Hakko 936, also a very fine product. Xytronics has a similar station, which is probably a bit less expensive. Bob, N7XY On Mon, Nov 15, 2004 at 07:17:47PM -0800, Ron D'Eau Claire wrote: > I have a Hakko 936 that I really like.

RE: [Elecraft] Temp controlled solder station
Bob - Under $ 100 is very easy to achieve with either new, refurbished or used soldering stations. It is a good time of year to shop for a station, since many mfg. and dealers offer year-end / holiday specials. For new stations, the Weller WES51 or WTCPT and Hakko 936-12 (ESD version) models have been quite popular with Elecraft builders. These models sell for under $ 100 at Fry's Electronics, Wassco, Contact East and a number of other dealers or distributors. IF you find a used Weller TCP series soldering station (WTCP, WTCPL, WTCPN, WTCPS, WTCPT, etc), I do repair and/or refurbish these at parts costs for Elecraft kit builders. Used units of the TCP series are available for $ 50 or less every week on eBay.

[Elecraft] soldering iron story
Plane is to pilot as soldering iron is to electronics hobbyist. You can get a nice controlled-temperature soldering station at Sears, these days. Weller WLC-100 I think. Handy. I've had my Weller WTCPL since 1979 and would buy a new one, if I had to. But I don't have to, ha! This one still works perfectly! I have co-workers who aren't as old as my soldering iron. And to have the thermal mass on demand that only a Curie-effect thermostat can provide, is worth it to me. If I bought something else, I'd be wary that tips and other parts might eventually become inaccessible. The value is remembered long after the price is forgotten. __ Do you Yahoo!?

[Elecraft] KIO2 outside of K2
Hi all, I noticed that the KIO2 option uses a standard conversion chip like the Maxim 232, but does not use optoisolators. I guess the optoislators would not help when the KIO2 is inside the radio close to the other circuits. I also noted that the KIO2 can generate noise. Has anyone ever considered using the KIO2 with optoisolators added outside of the K2 chassis? My limited experience with my homebrew interface for a Kenwood CAT says that it would be much easier to eliminate the interference, and since the cable to the computer is outside the radio, the RS232 interface being outside the radio would not be much of an inconvienience.

Re: [Elecraft] KIO2 outside of K2
Steve, If the cable to the computer is built as specified in the KIO2 (or KPA100) instruction manual, noise pickup is minimized - the frame ground (pin 1) is connected only at the K2 end, and any noise on the computer frame ground is not conducted onto the cable. I would expect any improvement gained by using optoisolators to be minimal - perhaps someone should try it and see. Optoisolators are useful as a solution for ground loops in situations where they are likely to occur - such as instances when the connecting cable parameters are not known or specified. One advantage to optoisolators is that separation of the signal ground in addition to frame ground is possible, but proper care must be exercised in the design to assure that this isolation is still present after the circuit is packaged (frame ground can be inadvertently made continuous even with the use of optoisolators by conduction through a metallic enclosure). There is little advantage to be gained by separating the signal ground for RS-232 level signals unless the cable run is very long (more than 50 feet or so) and ground reference level shift creates a problem with the switching levels at the receiver. For my $0.02 worth, I would not predict any improvement. 73, Don W3FPR - Original Message - Hi all, I noticed that the KIO2 option uses a standard conversion chip like the Maxim 232, but does not use optoisolators.

Re: [Elecraft] Alignment and Test, Part II
Peter, A probable cause is a soldering problem on the thermistor board. Examine it VERY closely, and if nesessary, remove it and re-do all the soldering. Remember that this little board does not have thru plated holes, so soldering on this board is more critical that for the rest of the K2. Also check all other components in the PLL reference oscillator area for proper values and proper soldering. Look at the schematic to identify the components (RF Board sheet 1 of 4, upper left corner). 73, Don W3FPR - Original Message - just completed my K2 to the Alinment and Test Part II.

RE: [Elecraft] Soldering stations.
Yep, just saw that myself, Bob! That's my motto: "Ready, FIRE!, Aim..." I consider a quick and easy method of changing temperatures essential in a soldering station. I used to have trouble with the "blob" method of removing enamel and a few other simple chores such as using desoldering braid that I could do easily in the field with an uncontrolled temperature iron. The problem is that a 700F iron is too cool for many things like that. With the Hakko, I crank up the temp to 800F and within a couple of seconds those chores become simple. While I normally use a solder puller, sometimes braid is easier. The iron needs to heat up the braid enough for good flow, and do it quickly before the board or connector gets overheated, all the while heat is being lost up the braid. Braid is copper - a GREAT heat sink! Using a hotter iron prevents that problem by putting the right amount of heat on the joint through the braid. And blob-stripping enamel from wire is equally simple and fast with enough heat. Ron AC7AC -Original Message- Ron, I think you responded to the wrong message (about the KX1). :^) Weller also has soldering stations with an adjustable temperature control.

Re: [Elecraft] soldering iron story
The Weller TCP soldering iron must be the best thing since sliced bread. Got mine in 1971 or 1972. Has a black hard bakelite cased PU1D 24V PSU with a Bulgin miniature 3 pin power connector on the side for the TCP-1 soldering iron which also uses bakelite for the handle. This version may be UK specific, not sure. Still works fine after all these years, though could do with the 3 core silicon rubber soldering iron cord being replaced. Not seen these listed by UK Weller spares sources of late. Have also inherited a later TCP soldering iron with the thermoplastic cased PS2D PSU from my late father in law, G3UUA. The new thermoplastic though it may look smart does not hold up to abuse like the old hard bakelite did unless dropped. Not sure if the term bakelite is used in the USA, but a similar material was used for panel meters, tube bases and a multitude of other uses throughout the world. Picked up the matching desoldering attachment that replaces the TCP element tube at a junk sale. The rubber bulb has now finally perished with age. Anybody know of a source of replacements for these rubber bulbs? Checks with dealers at later junk sales have drawn a blank apart from thoughts they may have been used by the military in the UK.

Re: [Elecraft] Low voltage on AGC threshold
Mike: How accurate is your DMM? The 8v and 5v regulators should still produce 8 and 5 volts even with a slightly low supply voltage. Also, if the K2's internal voltmeter reads the same as your DMM, that tells me your DMM is reading low because there is a diode in the K2 power line which will make the K2 internal voltmeter read LESS than an accurate external DMM. Only if the external DMM reads low would the two voltmeters agree. Try to check your voltages with a different DMM. My guess is your problem is NOT low voltage all around. Good luck. 73's John AA0VE Mike, W8ENG wrote: This is an update to my earlier post. I touched up a solder joint and reassembled the radio.
