[Elecraft] K2 - REMOTE KPA100/KAT100
K2 6442 is working fine and I was able to make a number of contact on Field Day using an antenna hung from a crane at 103 feet. However, success at home has been frustrating as I am in a hole, in a valley, at the low end of the sun cycle, in a community that does not allow antennas. Currently, I am using a High Sierra screwdriver with tuned radials that I have to set up and break down every time I use it. 15 Watts max has not resulted in very many stations hearing me. To make up for all of the above shortcomings, I am looking into ordering the KPA100 and KAT100 and mounting them together in the Elecraft enclosure. However, I am a little leery. This is an after market modification and will not include the awesome assembly manual that allowed a neophyte like me to successfully build a K2. I would like to hear from anyone who has built a Remote KPA/KAT100. Any comments are welcome. However, I am most interested in the following: 1. Who has the best, most complete instructions on how to successfully build this mod? So far I have only found one source on the net. 2. What are the pitfalls that an inexperienced builder should be watchful for? 3. Any other comments welcome. Thanks.

[Elecraft] K2 6442 ON THE AIR
Thanks to the patient assistance from Don, W3FPR K2 6442 was on the air last night (for the first time) with N7CMJ, Less of Evergreen, MT. We initiated our contact on 2m to coordinate and then made contact on 10m and 15m. According to N7CMJ my signal was 5/5 with 5 watts. His frequency readout was 28.499.09 to my 28.500. I guess that is good enough for now. All I have left to do is install the 60m accessory and the KIO2 (looks intimidating). All was not perfect however. Just a couple of problems cropped up. 1. I am getting a flash of HiCur occasionally when I transmit. The Current setting is at the recommended 2.0 and I was only running 5 Watts. 2. According to N7CMJ the Elecraft mic sounded great. Not so with my Heil Traveler Headset. For reasons unknown, it caused a thumping or pulsing sound in the receiving station. I do not know what this could be and neither did Less. Per Heil instructions, I am using the same adapter as that used by Kenwoods. Suggestions more than welcome on the above issues. Again, thanks to Don, Less and also Gary (W7GFB) for all the help getting on the air. Chris K7CJA K2#6442 P.S. I am hoping to get on the MT net this AM. -- View this message in context: http://www.nabble.com/K2-6442-ON-THE-AIR-tp17302568p17302568.html Sent from the K2 mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] KSB2 INSTALL - RX LOST
Just throwing this out there while I start backtracking to figure it out. I have installed the K160RX, KAT2, KBT2 and now the KSB2. Prior to install I was able to hear activity on the bands. After install I could hear very few stations. On the ones that I could hear, it was barely so even with full AF gain and the SWR meter would barely deflect. This AM a friend tried to TX on 40m at 5, 10 and 50 Watts. So it seems I have induced a deafness problem. I have also installed the Elecraft mic with the Rbias resister and jumpers. I was missing one jumper but used one from my computer junk box. It was slightly different as it does not have a top like the ones Elecraft provided. I include this on the off chance this might mean something to those of you far more experienced and knowledgeable than I. I have attempted to TX into a dummy load and I get dot deflections on the SWR meter in the 5-7 range but a separate watt meter indicates well below the set power. Anyway, if anyone has any thoughts on tracking down this gremlin they are certainly welcome. Thanks 73's, Chris K7CJA K2#4662 -- View this message in context: http://www.nabble.com/KSB2-INSTALL---RX-LOST-tp17258436p17258436.html Sent from the Elecraft mailing list archive at Nabble.com. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] KAT2 INSTALL - VOLTAGE AT U4, PIN1
After listening for a while and reviewing basic and advanced operation I am now beginning the install of the K2 accessories. For the KAT2 I am getting .001 V at U4/PIN 1. Is this close enough to zero? If not, please advise the best way to trace back the origin of this voltage. BTW, in TUNE I am at 3.8. Thanks.

Re: [Elecraft] KAT2 INSTALL - VOLTAGE AT U4, PIN1
Don: Thanks again. Good news. And thanks for the hint I do have the k60xv to install so this is a big help. I am kind of going by guess and by golly on what order I install things. I have started with the KAT2 and had planned to move to the SSB2, but I may do the 160m accessory first. Suggestions always appreciated. 73's Chris Don Wilhelm wrote: Chris, Unless you are really careful with your DMM leads and have zeroed your DMM, *any* reading of .001 volts (or even up to .003) can be considered zero under normal conditions because it is likely noise being coupled onto the DMM leads from sources unknown. So, yes, that is close enough to zero. Additional hint: if you are ever going to install the K60XV, use a 470 ohm resistor at the R6 location rather than the 47 ohm value. If you have the K60XV in hand, you will find an extra 470 ohm resistor just for that purpose packaged with the kit. 73, Don W3FPR MTcja wrote: After listening for a while and reviewing basic and advanced operation I am now beginning the install of the K2 accessories.

[Elecraft] KAT2 CALIBRATION - R 1 2
I am in the process of calibrating the tuner. I think that I have R1 set using an external meter. However, with full deflections of R2, the LCD indication does not move from 0.0r. Using my DMM to measure resistance of R1 at the center terminal I got 36.0k. The closest I could get with R2 was 36.08k (not in TUNE mode). Please let me know what to do to resolve this issue. Thanks again for all the help as I approach completion.

[Elecraft] K2 6442 - Chasing zero on alignment.
I have been working through the alignment prior to final assembly on my K2. Up through the receiver pre-alignment things seem ok. However, I seem to have some problems on the TX alignment on page 80. To do this process I am using the integrated meter and the Elecraft Dummy Load. In addition, I do not have sufficient understanding to reason out things that do not seem to work as expected. I have done the procedure several times and it seems that I have to make bigger than expected changes each time. Here is what has happened: 1. Larger than expected changes; 2. BAND +/- skips band and have to manually tune to frequency or remains on same freq; 3. When aligning 17m adjusting c32/4 does not change power indication. Indication will flicker up or down by .1 watt. If anyone has any suggestions I would really appreciate it. Is there a way to get everything back to a default starting place and start over with the whole part III process? I am really hoping to get this resolved so I can do the final assembly and install all the accessories. I do not want to do that until I am relatively confident that the alignment is ok. Thanks in advance for the assistance.

[Elecraft] K2 6442 About to be Born......
Alignment pains 6 min apart Up to now all TA results have been within specs. All the way to tx alignment on page 80 where confusion entered and ignorance poked his head in the delivery room. The second column on page 80 starts stepping through the bands after aligning L3 4 on 80m. However, there is no mention of using TUNE in conjunction with the procedure like the tx adjustment for 40m done previously. Should that be assumed even though the instructions do not indicate? Any assistance on this in order to get this baby delivered and accessories installed will be greatly appreciated.
