RE: [Elecraft] Kio2 cablength
Sam, Since the computer to K2 cable carries only RS-232 signals, I should think 25 feet should pose no problem - why not just try it and report the results. It certainly will not break anything if you construct the cable as shown in the KIO2 or KPA100 manuals. However, do not use a standard computer serial cable - IT WILL CAUSE BAD THINGS TO HAPPEN TO YOUR K2 - the cable should have only TXD, RXD, and signal ground lines connected (and the shield at the K2 end), plus the handshaking jumper at the computer end. 73, Don W3FPR > -Original Message- > > Hi I was wondering if there would be a problem using a 25 foot length of > cable from my K2 to the computer. >73 and Thanx Sam KF4YOX > > -- No virus found in this outgoing message.

[Elecraft] K2 - #4970
Hi All, Glad to report that K2 #4970 is alive and well and living in Long Island NY. It took me a month to build it and the SSB, NB, and 160M options.

Re: [Elecraft] NiMH Battery Question
In a message dated 04/07/05 19:56:32 GMT Daylight Time, [EMAIL PROTECTED] writes: There are some small charge controllers out there, but a relay configured to open when the battery reaches full charge is the simplest. Reply:-- The problem with using a relay for solar charge control is the current needed to activate the coil of the relay. This could be as high as 100mA and with a charge budget available of only 250mA you would have to select the relay used with care. If a solar charge controller was seen to be necessary I would have thought a solid state version similar to the type Don Brown is making the kit for would have been a safer bet for minimising power losses in the control mechanism (pity these are only available in the USA as I could have used one). The usable solar power available for solar panels is usually calculated at 8hrs per day, though does depend on the seasons further away from the equator. With 8hrs @ 250mA that would equate to 2000mA per day which is the total rating of the NiMH cells being used. The charge needed would depend on the initial state of the batteries and what the consumption of the radio was to offset the available charge. Some device to monitor the battery voltage and an on/off switch would also work as a charge controller in this case at probably even less cost. With regard to the point when full charge is reached with NiMH cells, I was checking out a motorcycle racing ignition pack last week and using a commercial charger built for the purpose, the end voltage for a 6 NiMH pack was 8.40V, which equates to 1.40V per cell. These guys can get exceedingly upset if they are leading a race and the batteries die, so had to ensure that all was OK. The point with this type of cell and many others including gel cells is that the initial voltage at the end of charge is higher than the nominal voltage of individual cells, though the voltage soon droops with use to the nominal voltage of approx 1.20 to 1.25V per cell. This carries on pretty well constant until the battery is almost empty then there is a rapid fall as the battery dies. Under these circumstances using NiMH cells it would be better to maintain the charge to prevent the voltage falling as was recommended. Understand with the earlier NiCADS it was better to take them as far as possible before recharging otherwise cell capacity could reduce.

[Elecraft] KPA100 - left, right, counter clockwise?
Hi folks - I wonder if somebody can confirm part of the instructions on page 47 of the KPA100 manual. I have the KPA100 connected to my K2. The KPA100 is lying with the heat sink down and the fan to the rear next to my K2. In this position all component labels are upside down. The errata for page 47 says to "touch the left side of R12 (the lead closest to RFC5)". If you were looking at the board with the component levels "right side up" this would be the RIGHT side of R12. SO - this makes me wonder about R6. When the manual says "rotate counter clockwise" does this mean counterclockwise when you are looking at the components from a position where all the component labels are upside down? It seems that it must based on how the left side of R12 is described. What is correct?

RE: [Elecraft] Interesting Tuner applet
While a T-network is not necessarily lossy at moderate impedances, try using one to load up a short antenna. For example, a 25 foot end fed wire on 80 meters will show an impedance of about 3-j550 ohms. A T-network tuner will match it okay, but with a loss of 7 dB! That's a loss of about 79% of the RF passing through the tuner. That's why I might T-matching network for moderate mismatches in the vicinity of 50 ohms, but avoid them for wide-range matching of multi-band antennas, most especially any antenna that is less than 1/4 wavelength long. A T-match is good at producing a 1:1 SWR to the rig okay, but so will a dummy load. The Elecraft ATUs, by the way, use an L-network instead of a T. That's a whole different "animal" and a lot more efficient. Ron AC7AC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] Interesting Tuner applet
Daan - Here is the match I get for your problem: Input C 226.6 pF Coil 1.2 uH Output C 174.7 pF SWR 1.0 Percent loss 1.0 dB loss 0.0 (actually this means less than 0.1, teh lowest value the applet shows) It is a bit different than yours and the automatch, but it is low none the less. I get the same automatch that you do. This points out that although a T-match can achieve a non unique match, there usually is not a significant difference in loss in these matches. Here is how I tune a T-match tuner, and the applet as well. 1. Set all controls at maximum. 2. Reduce the inductance untill you see a dip. It might be a shallow dip, or it may be a deep dip, but you should see a dip. 3. Reduce the output cap until you see a dip. 4. Reduce the input cap until you see a dip. 5. Tweak the inductor if the dip is not at 1:1. 6. Go back and tweak the output cap, input cap, and inductor to get to the lowest SWR. 7. If you still have a high SWR, see which control impacts the SWR the most. Turn it one direction off the dip. Tweak the other two controls in turn to get a dip. If the SWR is lower than when you started, turn the initial control in the same direction and tweak the other two controls until you get a new dip. Repeat unitl you get the lowest SWR. If the SWR is higher than before, turn the control in the opposite direction and proceed as above. 8. You may find that only two of the three controls affect the SWR dip. If that is the case, concentrate on those two. This all becomes second nature after doing it several times. I keep a cheat sheet on top of the tuner with the correct settings for each band/antenna combination. That makes band changes quick. You can also use those "Post It" pointers that administrative assistants use to show you where to sign a document to indicate proper settings. I hope that this helps. - Dr. Megacycle KK6MC/5 -- James R.

The range of the 1788 is 15-40m. The loop is formed from heavy-walled aluminum tubing and is welded to the butterfly tuning capacitor to minimize losses. Mine has been out in the Colorado weather for about five years without any noticeable deterioration and the antenna works well. I have used it in both vertical and horizontal orientations with good success. I like the convenience of a single feed-line connection, with the tuning control signal superimposed on the coax, avoiding the need for a separate control line. The built-in cross-needle PWR/SWR meter is a nice touch, too. 73, Gus Hansen / KB0YH ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Internal battery question
Charles - A well charged Gel Cell should have a voltage in the neighborhood of 13.2 to 13.8 V. It appears that you did not fully charge the battery, or the battery is incapable of accepting a good charge. Others have pointed this out as well, you need a charger/supply that is capable of of overcoming the Schottky diode voltage drop in the K-2. You might want to try charging the battery out of the K2 to see if it will take a charge and how that will last when reinstalled in tthe K2. The battery in the K2 is a bit undersized for extended QRP use at 5 W. This is exacerbated by the common use of float charging, which does not fully charge a Gel-Cell, or takes forever to do it. The use of a smart charger is recommended. There are some issues with using a smart charger, but they are covered in the technotes area of the Elecraaft site. - Dr. Megacycle KK6MC/ -- James R.

Hi Gerhard, Not an answer I'm afraid, but I recently opened up my KPA100 to try to find the whole answer to the low power out problem. Even though my KPA100 puts out 100w on all bands, I don't like something lurking ready to bite!

No visible sign of overheating, and values OK. T1 is OK, the transistors are healthy, the fan runs all the time when power demand is over 11W, and in a pileup the heatsink does get warm but not hot.

[Elecraft] Temperature with KPA100 and XV144
Hi list, I have run into some minor problems regarding temperature rises with the mentioned devices and like your opinion/solution. 1st, the KPA100. I noticed that even when I only answer some CQs in a contest (CW) the fins get very hot - of course the little fan fights it. Not to speak of CQing myself. This is only possible with another fan on top. (I admit that I didn't dare not using this additional fan). 2nd, and here it's really bad - or let's say inconvenient at least. The XV144 shuts down after a few CQs in CW at 20W - operating in normal room temperature. Since the cooling is done on the bottom and there are no fins I expect it not to be too easy to cool it. What are your experiences/solutions? What can be done without two additional fans (and wires and weight)? Or can a small fan be added to the XV like in the KPA100? 73 Gerhard ___ Gesendet von Yahoo!
