The shaft of the variable cap is an odd size (3/16"?) and so it helps to have access to a lathe to make a custom adapter. But it can be done a number of ways. Next you make a front panel and mount the Command set chassis behind it with spacers - about 3/4 inch. New dial is a disk of metal. plastic or even cardboard. A window with a bit of Plexiglas lets you see the dial, and a few dial lamps to light it up are a nice touch. A Spot switch and other controls can be put on the panel as well. 73 de Jim, N2EY ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Thanks Dudley - My mate carried out a series of test (when he heard I had gone deaf) and he reckons (surprisingly) that the thumb is the most sensitive spot.

Re: [Elecraft] SKN rigs - OT Old Stuff Comment
>Well, there you are! "Restorable" ARC-5s are expensive but junkers aren't. Most have been ham-hacked into oblivion. Today, it would be a shame to deface or modify in *any* way WWII-era military radios that have managed to avoid 60 years of ham defacement. Please, use a "pre-hacked" unit if you intend to actually put one on the air. The famous WWII "command set" (ATA/ARA, SCR-274-N, AN/ARC-5) transmitters actually perform rather well when left all original and operated in the manner which the original engineers intended. Leave it to a ham armed with not much more real radio engineering knowledge than how to use Ohm's law to completely "re-design" (i.e., destroy) a set. Most of the post-WWII ham mag articles detailing the faults of the original designs are based upon pure myth and lack of knowledge by the author. I have all-original AN/ARC-5 and SCR-274-N systems (radios, controls, racks, mountings, tuning shafts, cables, connectors, etc.) that took me many years to complete. The receivers and transmitters are by far the easiest components to obtain. eBay is a great resource for hacked or original condition units. Those who are interested in this great old technology, both historical, operational, and technical, may want to join two other qth.net lists: [EMAIL PROTECTED][General military radios of all eras, but WWII predominates] [EMAIL PROTECTED][WWII aircraft radios, especially "command" sets] Traffic can sometimes be light on these lists. But beware...on either of the above lists, inquiries about modifications to all-original gear or major "re-design" of lightly-hacked gear, may get a somewhat cool reception. 73, Mike / KK5F ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] Low BFO Output
Tedd, Yes, a low BFO voltage would cause poor receive sensitivity. I doubt that pulling the crystals caused the problem, but the new crystals may fix it. While you are removing things, you may want to arbitrarily replace the NE612 at U6 just in case. I recently repaired a K2 with a similar problem with one of the K2s I built last May - I can't say just what the problem was (most likely the crystals), but this one had failed before and replacing the NE612 appeared to correct it the first time, but after having a similar failure a second time, I replaced the crystals, varactors, inductor and the NE612 - I do hope and trust that it will stay fixed now (no, this was not a solder connection problem). 73, Don W3FPR > -Original Message- > > First some history.

RE: [Elecraft] Connecting Kent Straight Key and Paddle
Jeff, I have mine already configured and ready to go. I used a Radio Shack Stereo Y cable RS 42-2463. Connected the paddle to one side of the Y cable with a RS 274-284. From the straight key I used a RS 274-274 in line stereo jack that I modified in accordance with the K2 manual page 95 figure 8-1 and a short pice of 1/8 stereo cable (about 6") RS42-2387. I plugged the straight key into the modified stereo jack and the 6" extension with the stereo plug into the other Y cable connection.

RE: [Elecraft] Connecting Kent Straight Key and Paddle
You probably are! You have the right connectors. For the paddle, determine which paddle is going to be for dots. For most right-handers, the thumb is the dot, but there's no standard. Use a three conductor cable (2 conductors and a shield, e.g.) and connect the three wires to the paddle, one for dot, dash and ground. I don't know how the Kents are set up. Obviously if they come with a cable, you use that one. If not solder the wires to the wire lugs provided or whatever attachment scheme Kent uses. The stereo plug is made with three sections each insulated from the other. The tip is appropriatedly called the TIP, the RING is the next section down, and the large metal barrel is called the SLEEVE. Slide the plastic housing for the plug onto the cable first. Solder the dot wire from the paddle to the TIP connection inside the plug. Look at the terminals inside carefully and you will see that it is clearly the center one. Measure from the tip to the terminals with an ohmmeter if there is any doubt which is the proper one. Solder the dash wire from the paddle to the Ring. You will see that that one is stacked below the tip connection. Again, to be sure you can measure continuity from the ring to the terminals to see which one is right. Solder the ground wire from the paddle to the sleeve. That is the large tab that sticks out with some pieces on it to crimp the wire for strain relief. There usually isn't any doubt about this one. You will usually see a little hole about a 1/4" or so up that tab to solder to. Screw the plug housing on and it is done. Plug it into the K2, make sure you have selected INP/PDLn from the Menu and give it a try. If it works and you get dots on the proper paddle, you're done. If it's backwards, just change to PDLr. Do the straight key the same way except you are going to be connecting only to the TIP and the SLEEVE of the stereo connector. The Ring is not used. On the K2 Menu select INP/HAND or you will get a string of dots every time you close the straight key. Hope this is what you were looking for. If not post again. I'll be in and out all evening as we don't do anything on Christmas Eve. Merry Christmas, Jeff.

RE: [Elecraft] Connecting Kent Straight Key and Paddle
Jeff, Connect your paddle as a couple other folks have suggested - wire the dot side to the tip of the stereo plug and the dash side to the ring. Then add 2 diodes - one each to the Dot and Dash lines (it doesn't matter if the diodes are at the key or at the K2 end of the cable, take your pick) - the anodes connect to the paddle lines and the cathodes are connected together and connected to the straight key (of course, the 2 keys must have their ground side connected to the sleeve of the plug too). Be certain your K2 is set for INP PDLn or INP PDLR in the menu, and also be certain the Auto-detect feature is set on - from the menu INP, press EDIT then tap DISPLAY - if you see ADET OFF, tap display again to turn it on. 73, Merry Christmas and Happy New Year, Don W3FPR > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Behalf Of jrb > Sent: Saturday, December 24, 2005 4:43 PM > To: elecraft@mailman.qth.net > Subject: [Elecraft] Connecting Kent Straight Key and Paddle > > > Merry Xmas! > > I wonder if I'm the only one in the country thinking about this stuff > on Xmas Eve. > > Anyway, I'd like very specific instructions about connecting it to my > K2. > > For instance what kind of plug (for each wire) and how soldered to > the plug. > > Just to take my best guess I've already bought RS Part 274-284 <1/8" > stereo phone plug>, and wonder > if these will work.

RE: [Elecraft] Replacement for K2 Frequency Probe Assy
Jeff, You WILL need that frequency probe working to properly finish your K2. You can request a replacement 10 pf cap from Elecraft (or buy the complete probe kit), but in the meantime, most any 10 to 15 pf capacitor will function electrically, so find a source for one and use it until your replacement arrives. If you don't have one in your junkbox, Radio Shack MAY have something to offer, I just don't know for certain. If you can find a scrap VCR, TV, FM Radio, etc. somewhere, you should be able to salvage a small value cap from the RF section (use 2-20 pf caps in series, or 3-33 pf caps in series if you have to). It may not be as mechanically stable as the proper probe, but it WILL work. 73, Don W3FPR > -Original Message- > > Hi again. > > Unfortunately I broke my Frequency Probe Assy while making it > (couldn't get the glass capacitor to solder to > the probe tip).

RE: [Elecraft] K2 BFO drift
Aki, The BFO drift is not specified separately, so I cannot say if it is within spec or not. The entire frequency stability of the K2 is specified at less than 200 Hz after a 5 minute warmup, so you can check the overall drift and if it is excessive, perhaps a further look at the BFO may be in order. 73, Don W3FPR > -Original Message- > > I found that BFO frequency is 50-100Hz higher at power on. > It takes about 1-1.5 hours to be fixed at correct frequency. > > My K2 is #4504 so I believe it has been modified as Elecradt > made K2 BFO drift mod in 2002. > > My question is that 50-100Hz drift is within specification ? > > 73 de aki, ja1nlx > [EMAIL PROTECTED] > http://www.asahi-net.or.jp/~yy7a-ysd/ > http://blogs.yahoo.co.jp/charlie_whisky2000 > > ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

I'm considering a K2. The power out spec says <.5W... how much less? I'm not much of a QRP op, my amplifier only needs 100 to 150mW.

Well, Bill, if your output needs are that low, I suggest you add the K60XV module and use the transverter outputs to drive your amplifier. The K2 will go below .5 watts, but the power output at that level isn't super accurate. THIS Bill Coleman has owned a K2/100 for over 3 years now. It's a fabulous radio.

Re: [Elecraft] Emergency in 3 Land
".I don't need any transverters and the K1 just seems like a let down after the K2 and KX1." As an owner of a K1, K2 and KX1 I'd have to disagree. The K1 is a great rig (not just a "little" rig) and it's fun to work on and work with. If you need an extra challenge you could always build it for 160m!

RE: [Elecraft] K2 Alignment and Test, Part III: High current
Kathy, I suggest that you tackle the voltage drop problem before investigating the current draw. What size wire are you using for the power wiring? - it should be 16 guage or larger. Next check all the connections from the power supply to the K2 - they should be tight or well soldered. If no problem is discovered in the power supply wiring itself, measure the voltage at the power supply output terminals under the load in transmit - compare to the K2 display. The K2 display should show about 0.3 volts less than the power supply output due to the protective series diode. Lastly, check the soldering in the K2 12 volt path to be certain there are no high resistance solder joints. Once you get the voltage drop under control, the current should fall in line with what is expected. You receive current draw is about normal. 73, Don W3FPR > -Original Message- > > Power supply: SEC 1223 (23A) > Unit type: K2, no options installed > Passed Alignment and test, Part II > Passed all resistant checks > > Baseline voltage and current (backlight on) > 13.5v, 0.24A > > Transmit voltage and current into Elecraft 20W Dummy load (Using TUNE > function) > At 5W: 12.7v, 1.84A > At 10W: 12.1v, 2.98A > > The current draw seems far too excessive given the suggested range in the > manual.
