Re: [Elecraft] KXPD1 sensitivity
Try swapping the rubber grips. My craftsmanship left the wire on the dit side is a little bumpy, even after squishing it with needle nose pliers-it sends continuous dits with one of the rubber sleeves, but not the other. Also, make sure the spring steel levers are aligned so that they fit into the cavities molded into the rubber grips-if they are out of alignment even a little, they will be trapped against the contact wire-I had this momentary problem when I first assembled mine. (Also, at the risk of telling you something you don't need to know, check that your dit wire is not accidentally grounding to the aluminum bracket somewhere.) 73 Eric N0HHS I just got done with my KX1 construction, including the KXPD1 paddles. Another very nice setup from Elecraft! My question is how do I make the paddles less sensitive to touch. I find that the left side (dits) is very sensitive, and at one point, it started sending dits all on its own. I have squeezed the wires inside down as close to the PC board as they can be, but that didn't help. The right side of the paddle is working fine. Anyone have any other suggestions??

[Elecraft] Elecraft KXPD1 paddle -- minor upgrade
Hi Wayne, I've been kicking around several designs to mount a KXPD1 paddle to the right side panel of a K1, and later, a K2. Before I get too sporting, are you thinking of some sort of mount that would allow the paddle to be affixed to your other rigs?

[Elecraft] AGC and AF gain
Hi Elecrafters: I turned the AGC off the other day and was suprised to note a very noticible increase in audio volume. I had to back the AF gain down by a quarter to a third turn to get it at a reasonable listening level. I tried this on several signals and it was the same. It has always seemed that my K-2 has been weak in audio volume. Doesn't seem like this should be so. Any thoughts? Recheck the AGC threashold setting?

[Elecraft] XV144
I have a few queries on the XV144 transverter and would appreciate any comments from others who have built this fine addition to the Elecraft range. 1. The XV information sheet states that the maximum power of the XV50 is 20W and that of the XV144 and XV222 is 25W. The manual does not mention 25W. Has the XV144 and XV222 rating been increased since the manual was printed? 2. I notice that the top cover that came with my kit is made of steel rather than aluminum like the rest of the case. Is there any reason why aluminum is not used for the trop cover? I should have thought it to be undesirable to use dissimilar metals for the cabinet construction. 3. What is the recommended frequency coverage of the XV144 when it is used with the K2? The frequency range of the K2 on 10m is given as 28.0 to 28.8MHz in the specification. Does this mean that the XV144 should only be used on 144.0 to 144.8MHz? The XV144 manual suggests alignment be done at 145MHz, yet perhaps this is outside the recommended range when it is used with the K2. 4. What is the recommended warm-up time of the XVOVN crystal oven? I presume there will significant of the XV144 while the oven attains the 75C operating temperature? 5. With the 28MHz band pass filter aligned as in the manual, I notice that the cores of L15 and L16 are protruding out of the tops of the cans. Do others find this? Perhaps it is a tolerance thing. Many thanks; all comments will be gratefully received. 73 de David G4DMP ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Antenna questions
I am currently evaluating a trap antenna design that is described in the 19th edition of the ARRL Antenna book. There are two different dipoles represented there: one using a 60pF capacitor and twin-lead feed, the other using a 100pF capacitor and coax feed. The described advantage of both of these antennas is that they operate on 80, 40, 20, 15 and 10 meter bands to some degree. I have modeled these with little success using EZNEC. I expect that this is partly because I do not know how to add in the resistive component of the trap design. Please also note that I only have the DOS version of EZNEC. Any way my reason for all this is that I would like to build a portable vertical antenna for field use that has the touted characteristics. Obviously I would need to provide and attachment point for guy wires as well as an appropriate number of radials. My expectation is that the radials would be mounted about 2 feet above rock at the top of a mountain (East coast definition) where there is little or no support for a horizontal antenna. My question is: Does anybody know of a commercially available antenna that might serve? I have looked at a couple and find that they are very expensive ($100) and very short (30 feet tall). Alternate question is: Does anybody know why EZNEC does not seem to confirm that this design works well on all 5 bands?

You found one bad solder joint, so another one is quite likely. The last one I worked on with similar problems had a bad solder joint on the SSB board at one of the 3 pin headers - which reduced the signal getting to the IF amplifier a LOT.

Re: [Elecraft] AGC and AF gain
Greg, Yes, it certainly seems like your AGC threshold could stand to be re-adjusted. The recommended 3.8 volts will be close, but is not any magic number - the proper setting will vary from one K2 to another. I have seen good results with voltages as low as 3.6 volts, but none higher than 3.8 volts. If you have the XG1, you can also set the S-9 point on the S-meter at the 50 uV level (with the pre-amp on) by changing the AGC Threshold, S-HI and S-LO - it usually takes me about 3 times 'round the horn' to get everything lined up, so plan on some trial and error. I find that simply adjusting S-HI to set the S-9 level often limits the full range of the S-meter. Before you get started, be certain that you are evaluatiing the AGC on/AGC off difference on a band that is quiet - remember that an S-3 noise level will create some AGC action just from the noise. If you are working on a noisy band, the best 'cure' is to simply turn the RF gain down until the noise no longer activates the receiver AGC. (Reducing the RF Gain in the K2 does the same thing as reducing the AGC Threshold). The AGC will still work on signals stronger than the noise, even though the S-meter will not be as 'lively'. 73, Don W3FPR - Original Message - I turned the AGC off the other day and was suprised to note a very noticible increase in audio volume.

Now when we do the DC voltage checks we have a short to ground on the power jack. We have double checked the polarity of the caps and they are correct. Furthermore re-doing the resistance checks on p29, we now get P1 pin 16 shorted to ground and U4 pin 7 at 10 ohm. Would some Elecraft Guru out there give us some advice as where to look?

Re: [Elecraft] K1 Woes
Rich - If you have a power short, there are various ways to fix it. First, look for solder bridges around components, IC's, etc. If you don't find any solder splashes or bridges, you may have a bad part. Now, how do you find it? If the set was OK up until your last steps, then you only have to look as the steps that were mad since the last good tests. One very effective way I use is to use find shorts makes use of a digital ohmmeter, on it's lowest ohms range, set to display as many digits as possible. Hook one lead to the - (negative) power bus, and search around with your meter, touching various + points (such as IC power feeds or + leads of electrolytic caps) until you see the lowest ohms indication. There will be very small differences as you move around the circuit, and the closer you get to the short, the lower the ohms reading will be. This probably won't work with an analog ohmmeter, because you are looking for differences in the .001 Ohms area. Here is one area where a 5 or 6 digit meter really helps. I helped a friend find a DC short in his QRP kit this way. Good luck! - Jim, KL7CC Rich Lim wrote: Hey guys, I'm helping a friend Al, W9AFR with his K1 and were have run into a problem.
