[Elecraft] KX1 RF Power Question
I just finished adding the 30/80m module to my KX1 which has the KXAT1 ATU. While adding the 30/80 module I also installed the output power fix involving the two resistors in the driver/final. The unit seems to work FB but the output power is a bit lower than I expect. I measured the output power with an N8LP LP200 power meter on all four bands with a dc supply voltage, measured during transmit by the KX1 bat function of 11.9 - 12.0V. I made the measurements without the atu installed and also with it installed and in tune position. All bands showed SWR=1.0. My question is are these readings reasonable for these conditions? Freq.No ATUw/ATU 3.55 1.57W 1.02W 7.02 2.84W 2.72W 10.11 3.57W 3.36W 14.05 2.83W 2.74W Any ideas/suggestions would be greatly appreciated. 73, Craig K3OOL ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] Source of poor solder joints?
I agree with Don. Just the smallest, un-noticable motion of the joint while the solder is solidifying can produce a cold solder joint. That's why I always re-flow the connections that were done first to hold a component in place, like the corner pins on an ic. In fact, I often will go back and re-flow all the connections on a device after things have cooled off completely. It means taking twice as long to do the soldering but that's no problem because with an Elecraft kit the building process is at least half the fun.

[Elecraft] Noise Blanker 60m option for K2
I just finished building and installing the KNB2 andK60XV option boards. As usual with Elecraft it all went together FB and runs as advertised with no problems. I do have two complaints, however. 1. The K60XV has no toroids! What kind of Elecraft kit is it with no toroids to wind? Where's the fun in that? 2. For 120 bucks or so you only get two to three evenings of building fun. And that's stretching it, going as slowly as I could. Now what do I build? The only option left is the 160m board and that doesn't look like it would take very long to build. Help.

[Elecraft] XV60 'Partial Install'
I'm about to build the XV60 60m / transverter adaptor for my K2. At the moment, and for the forseeable future, I have no use for the transverter capability; I just want to try operating the 60m band. Is it possible to populate just the part of the board that pertains to the 60m capability and then make only the modifications to the K2 boards that have to do with 60m and leave out the transverter capability? Looking briefly at the XV60 manual it looks like most of the complexity in installing the board into the K2 involves the transverter portion. Any comments would be appreciated. 73, Craig K3OOL K2/100 #4790 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] Build Order: KPA100 KAT100-1 ?
I presently have a K2 with KAT2 internal tuner. I do not have a KIO2 installed. I've just purchased the 100 watt amp and external tuner. My question is which order I should build and test these two units: KAT100 first but no way to communicate with it to test it, or KPA100 first with no way to use it except for a dummy load? If I build the tuner first is there a way to tap in to the K2 enough to get the required communication signals to check the tuner out? Any suggestions from the group?

[Elecraft] FS: KAF2
I have a built KAF2 audio filter module for a K2 for sale. It works perfectly but is excess to my needs now that I have a dsp module.

[Elecraft] K2 Power Supply Voltage Range
Is there any advantage (or disadvantage) to running the power supply to a K2 at the upper end of the specified voltage range rather than in the middle or the low end. I'm thinking of more output power, or same power at lower current, etc. I'm not trying to 'hot rod' the PA of the K2, just wondering if there's any reason to run at one end of the spec limit rather than the other. I use a Samlex 1223 switching supply set at 13.6 - 13.8 VDC and it seems to be very well regulated under load (of course the K2 barefoot doesn't stress the supply at all). On SSB I get intermittent High Current messages on voice peaks with the power control set to 15.0 watts. I tried searching the archives about this question but the previous discussions seemed to be mostly about how high above the spec limit one can go without smoke. 73 and thanks, Craig K300L K2 4790 KSB2 KAT2 KAF2 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K2 Test/Oper Quirk
K2 4790 with SSB and KAF2 is up and working very well. I have noticed something with the Test/Operate function which I'm not sure is a defect, a quirk, or a feature of the firmware. On CW if I select test mode by pressing VOX the c indicator flashes slowly to indicate that the unit is in test mode, per the manual. Pressing the Tune button apparently starts the tune mode but the power indication is just 0.1to 0.2, indicating no rf output. That's all fine. However, if I change modes to sideband, or switch bands to a band that I left in sideband the unit stays in tune mode but there is no indication on the display. Several times I've been fooled trying to tune up on SSB but getting no output, the power display showing 0.1 or 0.2. Then I remember that I was in test mode on CW. If I change modes to CW the c indicator is flashing. I can then turn it off with the VOX button and then switch back to SSB and all is well. Is this normal? I believe I have the latest firmware that came with #4790. Thanks for any suggestions.

[Elecraft] K2 #4790 is on the air.
Just finished K2 4790 tonight. No problems in construction or alignment. It all seems to work per spec with the alignment by the book just using antenna noise and zerobeating WWV and/or CHU to check the accuracy of the VFO. One quick qso in the log with many more to go. My thanks to everyone on the email list for comments and suggestions and especially to the support people at Elecraft for quick answers to a couple of part identification questions. An excellent product made by excellent people. Now to try to make ECN this coming week. 73, Craig K3OOL K2 SN 4790 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] K2/SSB Construction
I just ordered a K2 and SSB adaptor so while I'm anxiously waiting delivery I'm trying to get the shack and bench ready for construction. I've downloaded and briefly read the manuals and I've come up with two questions (the first of many I'm sure). 1. Are there any mods (part additions or deletions) that need to be done to the base K2 if the SSB adaptor is going to be added? Is there anything I should watch out for to prepare the K2 for the SSB board? 2. Are there any recommendations for a vise to hold the PC boards during construction. I've got access to a Panavise with about 6 capacity jaws; is this big enough? Any thoughts will be appreciated. Thanks for the help.
