[Elecraft] Possible REALLY GOOD BUY on T/C Soldering Stn AND DE-Soldering Stn
Hi folks: Thanks to Tim Raymer, KA0OUV, for first mentioning this to me... FIRST - I have NO interest whatsoever in ANY of the companies referred to in the following comments. It appears that Circuit Specialists, Scottsdale AZ, is be offering what kinda appear to be Hakko-made temperature-controlled soldering and DEsoldering stations for some really extraordinary prices right now. At present, I know on no one who had bought and tried either of these particular devices, but they (physically) closely resemble Hakko-made products. So you're on your own at this point. I'm hoping that Elecraft's Chief Tech, Gary Surrency, will have time next week to visit Circuit Specialists to check out these devices and report to the reflector on what he finds. Here's what I now know... or have found... at Circuit Specialists... T/C soldering station (analog)... http://www.circuitspecialists.com/prod.itml/icOid/7307 at $34.95, this looks virtually identical to the Hakko 936-12 T/C soldering station. The one thing I have noted is that this device draws only 40W of power, implying that it probably offers a 40W heater, rather than the 60W heater available on the Hakko 936-x http://www.kiesub.com/hakko936.htm for $82. T/C soldering station (digital)... http://www.circuitspecialists.com/prod.itml/icOid/7508 at $49.95, and also 40W power consumption, this is not a bad buy, IF it truly is Hakko-made, and not a cheaply-made clone. This appears to be physically the same as the Hakko 937 T/C station, but with a 40W heater, rather than the standard 50W Hakko heater http://www.hakko.com/itnl/product.html?catID=1prodID=4. DESOLDERING STATION http://www.circuitspecialists.com/prod.itml/icOid/8013 at $119.00, this device appears to be physically to an older model Hakko desoldering station I think I saw a while back (though I can longer find a reference to it). The handle of the desoldering tool appears to be virtually identical to that currently used by Hakko. If it is Hakko-made, then this price is excellent! This is a 2-piece unit... power supply/vacuum pump, and hand-held tool. Please don't shoot the messenger if this info is not totally accurate, I can only report what little I've been able to find on the web. But it certainly looks to be very much worth further investigation. Finally, for what little it might be worth, Circuit Specialists is also offering tips for this line of products, and their nomenclature for the tips is (with the change of only letter in the nomenclature) virtually identical to that used by Hakko for their tips... not sure if this is just a fluke or not, but the tips also look like those sold by Hakko for their 936-x series of T/C stations. If anyone has further info, especially if it's first-hand info, on this line of Circuit Specialists products, PLEASE post it here. 73, Tom N0SS ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Companion External Speaker for the K2
Hello All: As some of you may remember, there was a development effort undertaken some time ago to produce a companion external speaker for the K2. Unfortunately the prototype -- dubbed the SP2 -- will not make it into production. However, I have compiled a 12-page article that describes the more critical construction details of the project for those who might want to duplicate the effort and produce their own version. The article contains over 20 photos, several construction diagrams, performance curves, a schematic, and a parts list. In brief, the SP2 uses a readily available front-firing 4 speaker mounted in an EC-2 enclosure to achieve superior sound quality over the stock K2. A small amplifier (with low pass and mute circuits) is included to increase the available audio drive from the K2. If you drop me an e-mail (off the reflector), I'll be happy to forward a copy of the article to you (PDF file under 500Kb in size). I will also be selling the prototype pictured in the article. You can contact me directly if you are interested in it. The price would be $150.00 USD plus shipping.

That doesn't mean that your peaks are not reaching 100w. I'm using the cross-needle meter in my MFJ antenna tuner. I've tried it in both peak and average modes. I understand that it's not a true peak-reading meter, and that my peaks will be higher than what I see on the meter. I am seeing quite low output in both peak and average modes, much lower than I normally see from a 100W radio. I can put the meter in the low power range (30 W) and the needle never gets close to full deflection. Keep in mind this is speaking very loudly, really almost yelling. If I speak in a normal voice, the needle doesn't make it above 1 watt in either peak or average mode. Obviously this meter is not going to be very accurate in the 1 watt range, but what matters is that the needle is barely moving, even on the low power range. This does not seem right. -- 73, Brian VE7NGR ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] SSB low output
Brian, Before you get too disillusioned with the performance of the K2/KSB2 on SSB output with the Heil microphone, what are you using to measure the TX output on SSB? It is essential to use an RF wattmeter that is capable of measuring true PEP, not just one of the joke instruments on the market that add a large capacitor across the meter movement when switched to so called PEP. A normal RF wattmeter will read very low on unprocessed SSB audio. You can go into the K2 menu to maximise the microphone gain and if necessary add a degree of audio compression which may help. Normally for HF SSB I use a PM-2000 peak reading wattmeter to get sensible results. MFJ have a dedicated PEP meter in their arsenal of equipment and it is also possible to adapt a normal wattmeter with an add on circuit to provide PEP measurement with an active peak hold circuit. There was a simple circuit using a single LM358 IC published in the RADCOM magazine in January 1989 that I have used to convert several of my wattmeters. E-mail me if you want to check that circuit out. Bob, G3VVT K2 #4168 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: [Elecraft] SSB low output
Bob and Vic make excellent observations about needing to measure TRUE 'peak' output. One way you can do that with the K2 itself is to switch the bargraph to ALC mode (press/hold RF/ALC). Now the bargraph will show you when you've hit full power output as set by the POWER control and the ALC kicks in to turn down the level. It reads backwards in this mode, so you should see at least one bar on the extreme *right* flicker on voice peaks. On some bands (e.g. 40) you'll probably see several bars light up, indicating more ALC action. But as long as the right hand bar is flickering, your K2 is making all the requested by where you have the POWER control. If one bar doesn't flicker, you can figure out how close you are. Just try setting the POWER control below 100 watts. For example, if you don't get a flicker at 100 watts, try 90. If the first bar flickers at 90, then you're hitting at least 90 watts PEP.

[Elecraft] K1 / KFL1-4 / Question
Group, Did the normal search of the archives and elecraft website, without luck. Biulding a KFL1-4 and got to the Receiver Alignment section. My problem is with the 15 meter section. Can not hear a signal what so ever. The 40, 30 and 20 meters I can hear signals. Can anyone point me in the right direction? I seem to be missing it this weekend.

It's reassuring to hear that I'm not the only one who couldn't get it to work even with the mod. I'll build the preamp and see how it works.

Re: [Elecraft] SSB low output
Brian, Have you checked things on the KSB2 - particularly the resistors (RP5 too) and the soldering of the Speech processor/compressor chip. While the HC4/5 elements are about 10 dB less than most other mics, you ahould be able to make up for that with the SSBA = 3 and SSBC = 2-1 pr 3-1. It does sound like you have a bad connection somewhere. 73, Don W3FPR - Original Message - I guess I just need to build an external preamp, though I'm not sure why my output without it is as low as it is. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] 4MHz Oscillator Calibration
My frequency counter probe gives me erratic readings during the 4MHz oscillator calibration. However if I physically hold the 10pF capacitor during the test the readings settle down much nearer the frequency of 12090 kHz +/- 30 kHz as described in the owners manual. Can I consider the test in range? Dave N1PT ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] Another PSK31 Power Question
I know this has been batted around here recently, but I have an additional question. When setting power levels are we all talking about using a single tone, as when I activate the Tune button in Digipan, or the two tone idling signal I get when pushing the Pause/Break key? Different power levels result. Which do I use when establishing the 50% max power limit ( 5 watts for my QRP K2)?

Re: [Elecraft] How to set up SSB
The option of OP1 or 2.2, etc in the filter selection is for receive only. However you still have to make sure that the BFO is place correct for the TX filter OP1 and the easiest way to do that is to set up with OP1 in FL1 on receive as was finally selected and match the BFO to that with Spectrogram. Otherwise the BFO can end up in totally the wrong place with adverse effects on the SSB TX audio. Unless this is a very recent KSB2, a good improvement to the SSB audio could be made by applying the KI6WX 2,2 or 2.5kHz modification to the KSB2. The BFO again would need resetting to match the new filter parameters. Believe Elecraft have now adopted the KI6WX 2.2kHz mod as standard on present KSB2 kits. An added benefit is that the filter passband ripple appears to be substantially reduced. I did the 2.2kHz mod and find the final result at about 2.3kHz bandwidth with very little passband ripple. All makes for a better sounding K2 on SSB TX. Bob, G3VVT ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] Elecraft CW Net Report for November 21-22
Hello All, The twenty meter net went well this evening but some local QRN just drove me off the forty meter net. A wall of noise covered everyone up so I let the net go free. Mr. Hammond was on the air so he may have taken the NCS slot at that point. I'll see an email soon if that was the case. I had never had the noise switch on like that before; very odd.

[Elecraft] K160 effect on 80/75m power
This may be normal, but wanted to check if others see a slightly reduced power output at the high end of 75m after installing the K160 module. After peaking L3 and L4 on 160m per the instruction manual, I notice that on 80m around 3.5Mhz, when the K2 power is set to 10w, I can only get about 9w out...and then at 3.99Mhz, I only can get about 8.5w out. Not sure if this will matter since I'm now building the KPA100 and will at most times be driving an amp at 60 watts from the K2/100, but curious to see if this is normal or if there some other tweaking I can do to get at least 10w on 75/80m when running without the KPA100. At the same power setting I get at least 10w out on all the other bands, including 160.

Re: [Elecraft] K160 effect on 80/75m power
Tim, The bandpass filter alignment for 80/160 meters is a compromise. The peak at 160 meters does not allow full 80 meter power out, and vice-versa. Set the slugs for about halfway between the 160 meter peak and the 80 meter peak. If further adjustment is required, balance out the settings on 160 and 80 meters so you have about the same output power in both bands -- BTW, you should be able to easily achieve at least 10 watts output, most K2s I build or work on will produce 12 to 14 watts on both 160 and 80 meters. 73, Don W3FPR - Original Message - This may be normal, but wanted to check if others see a slightly reduced power output at the high end of 75m after installing the K160 module.

[Elecraft] Possible REALLY GOOD BUY on T/C Soldering Stn AND DE-Soldering Stn
Hi Folks: Bill Tippett, W4ZV writes regarding the Circuit Specialists soldering station I recently wrote about: Hi Tom, N0SS wrote: T/C soldering station (analog)... http://www.circuitspecialists.com/prod.itml/icOid/7307http://www.circui tspecialists.com/prod.itml/icOid/7307 at $34.95, this looks virtually identical to the Hakko 936-12 T/C soldering station. The one thing I have noted is that this device draws only 40W of power, implying that it probably offers a 40W heater, rather than the 60W heater available on the Hakko 936-x http://www.kiesub.com/hakko936.htmhttp://www.kiesub.com/hakko936.htm for $82. I bought this unit in February this year to build my K2 and a roofing filter kit (using SMD caps) for my Orion. The invoice I got from Circuit Specialists describes this unit as: CSI-STATION1$34.95 CSI936 SOLDER STATION/CERAMIC HEAT ELEMENT STAND Looks like you nailed the source of this product since 936 appears in its description. I've been very pleased with this unit in building my K2, filter kit and KD1JV's AT Sprint 2 (mostly SMD). A spare heating element was also included with it. If of any identification help, all tips' model #'s are all preceded by the word AOYUE. 73, Bill W4ZV Looks like this might just turn out to be a Hakko-made product... or at least made by the same company which manufactures FOR Hakko. Thanks Bill. For what it's worth, I've shied away from recommending the other CSI T/C station, the Auto-Temp Soldering Iron Station with Ceramic Heater (SR-976N) from Circuit Specialists because a local bought one and two of the three tips which he received were UN-TINNABLE... they were received with some sort of oxidation on them which wee were never quite able to remove without damaging the iron plating on the tips. Other than that, that particular iron worked pretty well, if I recall. With all due respect to those who have had great luck with this (SR-976N) station, I'd personally still go with this newer T/C station. 73, Tom N0SS ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
