[Elecraft] K2 SPLIT/RIT/XIT LED
The Operations section of the K2 owner's manual, under Split and Reverse Operation, states that an LED can be added to the Front panel that will turn on whenever Split, RIT or XIT is in effect, and to see the Adding a SPLIT/RIT/XIT LED to the K2 application note. However, the app note doesn't seem to be on Elecraft's web page under either Technical Notes or the Application Notes link under Tech notes. Where can I find the app note? I'm just curious to see what adding the LED entails, not sure if I'd actually do it. Thanks 72 de N8PVZ ---bernie __ Do You Yahoo!? Tired of spam? Yahoo!

RE: [Elecraft] K2 SPLIT/RIT/XIT LED
Bernie, It is at http://www.qslnet.de/member/la3za/K2/modAny.html - furthermore if you want to put the LED in a keycap, you can see how that is done by following the links on Sverre's K2 page at http://www.qslnet.de/member/la3za/K2.html . 73, Don W3FPR -Original Message- The Operations section of the K2 owner's manual, under Split and Reverse Operation, states that an LED can be added to the Front panel that will turn on whenever Split, RIT or XIT is in effect, and to see the Adding a SPLIT/RIT/XIT LED to the K2 application note.

RE: [Elecraft] Funny power measurements
Fran, It appears that you have a problem with the power control mechanism there. Are you using the TUNE button to initiate transmit or are you using a key closure? If you are using the TUNE button, what power does the K2 display indicate? Delay doing your testing across each band and resolve the power control problem first. The power control circuits are not band dependent (even though your data may indicate that it is) - you may have some sort of spurious response in the transmit stages too. Check the frequency with the time base on your 'scope to see if it is anywhere near correct. 73, Don W3FPR -Original Message- Okay so now I have made Peak-to-Peak measurements with my O'Scope. KAT2 removed. 50 Ohm dummy load with 10x Probe attached. Measurements are in the table at the bottom of this email. It should be easier to read in Notepad. Although there is likely a bit more inaccuracy in my readings, consistency should be reasonably maintained. The readings are still mostly all over the place with 20 30 meters looking pretty good. 80 meters is still way off base. Something seems wrong here to me but I have no clue where to start chasing things.

Re: [Elecraft] OT: Difference between PN2222 and PN2222A?
Thank you all for the replies on and off the reflector. The side by side data sheet was good, although much of it is greek to me. Seems like the PNA is more common in the kits I've seen, and slightly more robust judging from the comments and the data sheets, but then the PN is the only one I can get locally. Go figure. Thanks for the help. -Ben K1NT ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

I don't think you need worry at 12 volts supply, either will work. The A suffix is just graded out to stand higher voltages than the .

[Elecraft] KSB2
Hi all, Although I operate almost no SSB, I built the KSB2 for my K2 (#4398) late last year so I could use the K2 for RTTY contests. It seems to do everything a well conditioned KSB2 should do except it exhibits about 30 dB loss through the on-board filter. Thus, the SSB output from the K2 is in the milliwatt range and the RX level drops very noticably with the OP1 filter selected. I haven't had the time to figure it all out, and it's a bit tough since my test equipment is limited to a DMM, old Tek scope, and a very old service monitor. Given the likely cost of commercial repair through Elecraft, I decided I'd just build another KSB2, and it came today. This will leave me with the slightly-under-the-weather unit for which I have no use. If someone would like to mess around with it, I'll send it to you. All I ask is a charitable donation. I'll suggest a favorite charity, but it and the amount would really be up to you. I'd be able to mail it as soon as I get the new one built and working (without it, my beloved K2 is dead, of course and I can't take that). I may have it built and done by the weekend. I'll pick the first email that arrives. 73, Fred K6DGW Auburn CA CM98lw ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] KSB2
I think you should keep the KSB2 until the new one is finished also, BUT... The statement without it, my beloved K2 is dead is not true. Just stick a couple jumpers in the short jacks (1 to 3), and a [I Forgot] pF cap in the big one, between 5 and 7 if memory serves.

[Elecraft] Re KSB2
Wow, THAT was quick. It will be on it's way to Don Wilhelm as soon as I get the new one built. Thanks for all the replies.

RE: [Elecraft] KSB2
Fred, take care not to put too much solder on the pins of the crystals when you install them in your new KSB2. One of the most common reasons for low gain is a bit of solder that puddled around the pin under the crystal can where you can't see it and shorting the signal path to the can. Remember, those are plated through holes, so when solder melts and flows on the bottom side, it's melted and flowing on the top side under the crystal too!
