[Elecraft] CW Keying characteristics-computer vs Bencher
I finally hooked up my computer keying circuit, 2N off the parallel port, to my K2 before the CQWW contest. I have noticed what appears to be a significant difference in the keying characteristic from the computer versus the keying from the Bencher key. The computer appears to have a significantly harder characteristic than the Bencher. This is observed in the sidetone as I have not checked it with a 2nd receiver. Has anyone else noticed this phenomenon? tnx 73's, Ralph W1ZK ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] SLA Battery charge Level
I said: When the battery is exactly at 13.8 volts, there would be no current. Bob, G3VVT said: In practice found over the many systems worked on professionally this is not entirely correct. However if one monitors the battery over a longer period after the float charge period has started the battery will start to take a small charge that eventually settles on the 25 to 50 mA region for small SLA's. It all depends on the float voltage and the size of the SLA, but with a float voltage of 13.8V and a 12V SLA does definitely occur. --- Yes, I was over-simplifying it. But a battery at 13.8 Volts will not take a charge with a 13.8 Volt source. What happens I assume is that the battery discharges a bit so it is lower than 13.8 Volts, and then the trickle charge commences. -- John said: 1) The total charging time using your method would probably be longer than forcing 1.6 amps until the terminal voltage reached 14.2. But it might also be healthier for the battery. -- Yes it will take a lot longer (overnight), and not overheat the battery, but this is how the original Powersonic recommendations were in the 1990s. I imagine they have changed. --- John said: 2) If the SLA voltage got below 10.5 volts, you might initially draw more than 1.6 amps, unless your 14.39 volt power supply is limited to 1.6 amps. --- Yes this is true. But the powersonic web sight had recommendations for the amount of drain a _gell_ cell would take before it was permanently damaged. It might have been 10 or 10.5 volts. I think I chose 10.5 volts in my design, so the batteries would not suffer from over-discharging. I also monitored the voltage discharge during use so I would not damage the batteries. --- John said: I'm in the process of building a computer-controlled (PIC-controlled) SLA charger to enter into my local QRP club's annual builders' contest next Spring --- This is very exciting. Please let us know about the results. If you could leave the divice in the circuit during use you could design it to warn the user when the voltage of the battery was getting near the danger point. --- -- I have had some requests for my circuit. Actually the ideas might help John in his design too. I will post the info on my website soon and let the list know. Regards, Steve, W2MY/5 --- Outgoing mail is certified Virus Free.

Re: [Elecraft] BUG night - new year's Eve
Here in the Pacifc Northwest, we've also added a twist: we've been running VHF SKN on the 50mhz and above bands, +10 up from the calling freqs (50.135, 144.210, 220.110, 432.110, etc.). It essentially runs from start of SKN (4p here) to midnight (0800z) with most of the activity in the 5p-7p range. We have a solid VHF contesting fraternity here, so it's a real hoot! We're a real friendly bunch, and having so many folks clustered around the same freqs really turns it into a party. So, if you're in the area, know some fellow VHFers, or there's a hint of aurora in the air, spread the word, tune up those rarely used bands, and join us! ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Gangue, Thanks for all the feedback on this. As I currently have no plans to use computer control with my K2 (with or without the KPA100) I think Sverre's method below looks like my solution.

Can I do the remote installation using the K102 on the pa board ? The notes I downloaded seemed to suggest that the k102 needs to be in the K2 . I looked at this also, as I am in the process of building a KPA100 which I intend to remote. I don't have the KIO2 in my K2. When the KPA100 is in a separate enclosure, the RS232 interface in the KPA100 will not work as it doesn't get the data in/out from the K2's processor. Instead the KIO2 does the translation to RS232. Therefore, without the KIO2, you can get the KPA100 to work remotely, but you will not get an RS232 interface. If all you want is to get the KPA100 to work, you will have to do the following: - Install an RS232 connector in the K2/QRP lid - Connect GND to pin 5 - Connect AUXBUS to pin 6 (KIO2 has 15 uH in series and 0.001 uF to GND) - Connect VRFDET to pin 7 - Connect 12V to pin 8 - Connect 8R to pin 9 (KIO2 has 3.9k in series) These connections shall be taken from connector P4 (Aux I/O) on the K2's control board. Alternatively, if the KAT2 is installed, all but 8R can be taken from it. I haven't tried this myself, but there shouldn't be too many uncertainties in this. However, the cost/effort of getting an KIO2, is not that much greater than doing the above, so I am still debating with myself whether it is worth trying. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

You've already said I am referring exactly to weight. Hard/soft by convention refer to the sound of the RF waveshape, heavy/light refers to the on/off ratio (weight). You're mixing terminology and confusing the issue. Keying weight is a function of they keyer. As has already been explained, when you use a paddle, you're using the K2's internal keyer, and consequently get the weight for which that is set; the K2 is making the dots and dashes. The Bencher generates _two_ opens/grounds, and is telling the K2 to make a dot or a dash. As far as the K2 is concerned, the computer is just a straight key, so any weight (and speed) is a function of the computer program you're using. The K2 has nothing to do with the dots and the dashes, it's just making RF when it sees key down. A difference is to be expected, both in weight and speed - you're comparing two different keyers (the K2's vs. the Writelog's). ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] CW Keying characteristics-computer vs Bencher
Ralph, Another, or an again way of saying what has been said is: You are assuming that the K2 sees the Bencher and computer keying as the same. If that were the case, they would bethe same. The K2 does NOT see the Bencher and the computer as the same. It sees the Bencher as triggering the K2's internal keyer and applies what ever weighting that implies. It sees the computer as a straight key so the dit/dah ratio is what ever you apply sending by hand. Except it is not your hand that is sending. It's the computer software program. So the weighting of of the computer program controls its keying ratio when sending by keyboard and the weighting of the K2's internal keyer controls the Bencher ratio when sending by paddle. 73, Paul ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] No tx below 1/2 watt
Gang, The Knightlites Milliwatt 'test is coming up. Sounds like fun. Was checking out my K2 at low outputs to see if there are any problems. Got a problem. When I set the tx below about 1/2 watt I get no output. Appears to work reliably at 0.5w but not below that. Works most all the time at 0.4w. If I set it to 0.1w, which is what I'd like to use, it may work for a while. Pressing 'Tune' when set to 0.1w kills it consistantly. I can set pwr to 0.1w and press the paddles and it will (usually) continue to work for a while, then die. I haven't dug into it yet to check the ALC circuitry but am wondering if anyone else is having this problem. Did a Google which turned up nothing, so must not be too common. Even when there is no output the K2 power indicator shows 0.1 or 0.2 or 0.3 (it alternates between these) but an external meter correctly shows no output.

Re: [Elecraft] Problems with display on initial alignment
Pete, Display problems like that are often caused by partially soldered connections to the LCD. The pins barely protrude through the circuit board holes and it is easy to get the solder to fill the hole without heating the LCD pin adequately for solder to properly adhere to the pin. I would suggest you re-solder the LCD pins from the top side of the board, making certain that the solder flows on the pin as well as the PC board. To repeat -- first check soldering, then re-check soldering, and when you have finished, check the soldering!!! (that fixes most problems). 73, Don W3FPR - Original Message - I wonder if anyone has come up with a similar happening on the first alignment (Panel, control board and partial main board) I had intermitant problems when I first put it together, so I dismantled it and checked for bad joints, component values, etc. I found I had not soldered a switch.

I did some more checking and discovered that bringing the K2 weight down to it's lowest value of 0.90, it was at 1.10, makes it closer.

If it is a keyer, it will generate its own weighting which may be different than the weighting generated by Writelog OTOH, if your Bencher is a paddle (as I suspect), it activates uses the dot and dash lines as input to the internal K2 keyer - that internal keyer is what determines the weighting from the paddle. Writelog forms the dots and dashes and sends its own version of 'proper' weighting to the K2. The K2 recognizes the input from the computer as a hand key type input (through the two diodes), and will not alter the length of the dots or dashes nor the spacing. Bottom line, if you can't change the weighting in Writelog, you will either have to settle for what you get, or set the K2 keyer weighting to match whatever Writelog is using. 73, Don W3FPR - Original Message - From: Ralph McClintock [EMAIL PROTECTED] To: W3FPR - Don Wilhelm [EMAIL PROTECTED] Cc: elecraft@mailman.qth.net Sent: Sunday, December 12, 2004 3:19 PM Subject: Re: [Elecraft] CW Keying characteristics-computer vs Bencher Don, The computer generates an on-off. Writelog does not allow any adjustment of keying characteristics. The Bencher generates an open or ground. Why does the K2 recognize the Bencher, a mechanical switch, as soft and why does it recognize the computer as hard? Ralph W1ZK - Original Message - From: W3FPR - Don Wilhelm [EMAIL PROTECTED] To: Ralph McClintock [EMAIL PROTECTED] Sent: Sunday, December 12, 2004 7:10 PM Subject: Re: [Elecraft] CW Keying characteristics-computer vs Bencher Ralph, There is little to nothing that one can do to alter the keying waveshape from the outside of the K2, so you are likely hearing something different than the keying waveshape. How does the computer program handle the keying 'weight' - I would expect that to be the difference you hear. Change the weighting characteristic in the program to something different (if the program allows you to change it) just to see - and then set whatever you desire. 73, Don W3FPR - Original Message - I finally hooked up my computer keying circuit, 2N off the parallel port, to my K2 before the CQWW contest. I have noticed what appears to be a significant difference in the keying characteristic from the computer versus the keying from the Bencher key. The computer appears to have a significantly harder characteristic than the Bencher. This is observed in the sidetone as I have not checked it with a 2nd receiver. Has anyone else noticed this phenomenon? tnx 73's, Ralph W1ZK ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] #4595 Progress
Good evening everyone. Finished the control board for K2 #4595 and all looks good.I think. I have Pin 13 on U6 and Pin 15 and 16 on U8 showing 0.F on the DMM with the Megohm scale. From the archives this appears to be common with some DMM's when the resistance is infinite. The meter is on auto-range and with these three pins the decimal doesn't even budge, just no change at all just like the meter was just turned on and the test leads not in use. So with this being said I presume all is well. I have checked the soldering, rechecked the soldering and checked it again. Any thoughts? Ed, N0EHQ PS, finished the front panel and all the checks were in the green. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] remote KPA100 summary
--- David Toepfer [EMAIL PROTECTED] I was wondering how I could build a K2 and keep it light and QRP portable without having to actually remove the amp every time I wanted to move it. Puting a KPA100 and a KAT100-2 in EC2 case, is that possible? --- Bill Flynn AIØC [EMAIL PROTECTED] Lyle Johnson, KK7P (ex-WA7GXD), has done this. He's written it all up on an excellent Web page that you can view at http://www.fidalgo.net/~wa7gxd/k2kpa100.html. --- Paul Clay [EMAIL PROTECTED] Has anyone implemented Lyle Johnson's (KK7P's) suggested method (see http://www.fidalgo.net/~wa7gxd/k2kpa100.html#NOKIO2) of running a K2 and KAT-100 combo without an installed KIO2 (or KPA-100)? --- Sverre Holm [EMAIL PROTECTED] The question of the KPA-100 external to the K2 surfaces from time to time, and there are two descriptions of how it can be done. To find them you may check the Unofficial K2 Modifications page at www.qsl.net/la3za/K2/mod.html, go to General mods and then KPA100. --- Tom Hammond [EMAIL PROTECTED] Please visit: http://www.fidalgo.net/~wa7gxd/k2kpa100.html For (I think) all the info you should require on this subject --- Don Wilhelm [EMAIL PROTECTED] Yes, it IS do-able and has been done. In fact, I just received my EC2 enclosure and am about to do it myself. Check out http://www.fidalgo.net/~wa7gxd/k2kpa100.html to see how. In addition to the external enclosure, you will need the KIO2 option in your base K2 so it can communicate with the external KPA100. --- Bob Nielsen [EMAIL PROTECTED] Is it recommended to integrate the KPA100 with the K2 and get it all working together before remoting it in the EC2? --- Lyle Johnson [EMAIL PROTECTED] In the initial KPA-100 checkout, I had mine laying upside-down on a thick book (must have been a Windows tome...) with the cables plugged into the open-top K2. Once the KPA100 is checked out in this fashion, cal done, etc., I don't think it matters which box you put it in. --- Eric Manning [EMAIL PROTECTED] YES! That way, if any little glitches pop up when you remote the KPA-100, you can eliminate a lot of possibilities up front. For instance, if there are communication problems when it's remoted but it's OK when in the single box, you can focus on the RS-232 path between the two microprocessors . It's just the same principle of building a piece of the kit, then testing it before building any more, which Elecraft always follows. --- [EMAIL PROTECTED] My question for those who have gone through this is if there is a recommended order of construction that makes integration and/or check-out of the various components easieror more logical. --- Lyle Johnson [EMAIL PROTECTED] Yes, 1) Build the KPA-100 into the K2 and see that it works. 2) Build the KAT-100 in the EC2 case, connect it to the K2/100, and see that it works. 3) Build the KIO2, remove the KPA-100, and verify the K2/KAT-100 combination works. 4) Put the KPA-100 into the EC2 with the KAT-100 and verify it all works. --- Don Wilhelm [EMAIL PROTECTED] Yes, do the KIO2 first, but check out the instructions for mounting the KPA100 in the EC2 while you are building it - the inductors on the KIO2 connector/header board must be changed to toroids or other chokes that will carry the additional current. Other than that, I can think of no other particular order, but you may want to build the KPA100 before the KAT100 so you can check out the tuner at full power. --- Bill Acito W1PA [EMAIL PROTECTED] fyi, consensus (6 or 7 emails) seemed to be if you want to swap back and forth from a QRP to the 100W version of the K2, then mounting the KPA100 (and KAT100) in a seperate EC2 is the way to go. Most (not all) who responded found swapping the lids tedious, and dangerous (possibly dropping a heavy lid into the K2) --- Bill Acito W1PA [EMAIL PROTECTED] Yes, and was still described as faster and safer. http://www.qsl.net/la3za/K2/modAny.html#KPA100 --- JEAN-FRANCOIS MENARD [EMAIL PROTECTED] Now I have updated my website about building a KPA100 and KAT100 in the same enclosure, as advertised by Elecraft with the KAT100-2. See my link: http://homepage.mac.com/jfmenard/PhotoAlbum29.html Comments or questions are welcome !!! [...] --- Bob Nielsen [EMAIL PROTECTED] You will need a KIO in addition to the EC2, KPA100 and KAT100-2. You can find full information on KK7P's website at http://www.fidalgo.net/~wa7gxd/k2kpa100.html. --- JEAN-FRANCOIS MENARD [EMAIL PROTECTED] Add to Address BookAdd to Address Book If you need more photos of that setup, look at my website... I did thing setup 2 weeks ago. Very easy with the latest version of the KAT-100-2. http://homepage.mac.com/jfmenard ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
