Re: [Elecraft] KAT100 woes... Time to 'fess up...
in short, I had the RF IN and ANT1 connections reversed! Ah yes, I seem to remember whining on this very reflector when my brand-new K2 didn't hear very well during initial alignment. Turns out it helps if you flip the coax switch over to the main antenna from the dummy load. -- Ward / KG6HAF ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] KPA 100 Resistance Checks
I am building the KPA 100. I have just tried the resistance measurements on page 41 of the Alignment and Installation. Sounds like you are maybe running into the photoelectric effect on the PA transistors too. Do you have a strong light on the workbench? http://www.ac6rm.net/mailarchive/html/elecraft-list/2003-11/msg00574.html -- Ward / KG6HAF ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] KPA100 Problem still exists, but some new measurements
Now: I removed Z1 and found the voltage measured at the collectors of Qs 1 and 2 to be -0.4V (J3+ is ok now). I don't know where it could come from. Hi Gerhard: Dunno if this is related, but I got a small voltage J3 by shining a bright light on the final transistors. There is some sort of photoelectric effect. Your numbers are close to what I measured then: http://www.ac6rm.net/mailarchive/html/elecraft-list/2003-11/msg00574.html -- Ward ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] wobbly knob
My K2 AF gain knob is getting really wobbly, and seems to be getting worse. Yeah, same here. And the power pot is a little wobbly too -- I guess because these two are the most used (for me). My radio is about 13 months old. Think I am too lazy to actually fix it until it breaks, but maybe worth ordering a replacement or two to have on hand when it does... -- Ward / KG6HAF ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] OPT1 low volume - solved
Many of you offered help with the low signals I was getting when I switched in OPT1 on my newly built SSB adapter. Thanks to Gary explaining how I could just whack on the signal path through the ladder filter with one of my multimeter probes (not even connected to the multimeter) and use the resulting static and noise to trace the circuit, I worked backwards from the output jack and located a capacitor (C11) whose lead was broken off and floating in a small fillet of solder on the top of the board -- so it looked fine but made a crappy connection. I've no idea how I achieved this miraculous condition, but locating it with this technique took maybe all of a minute and a half. Wow. Since this cap is a 103, Elecraft even had the prescient (but spooky) foresight to include a spare! A few moments with the soldering iron and now all is well and the rest of the SSB checkout went without a hitch. I am embarrassed to say how much time I spent chasing this. Hope someone, someday, finds this post in the archive and it saves them much headache.

[Elecraft] #26 vs #28 wire
Today I decided to rewind T2 on my SSB adapter in an effort to correct my low signal level -- even though it looked fine and beeped-out well and yadda yadda. Anyway, I have LOTS of #26 wire left over from the K2 and KPA100. Any reason I can't use that instead of #28 to do this? (Is the difference enough to drop a turn or something?) Thanks, -- Ward / KG6HAF P.S. Turns out I didn't blow my IF amp the other day. Yippie!

[Elecraft] Ooops -- think I fried the IF amp...
Well, I finished the SSB adapter for my K2/100 tonight and slapped in. All worked until I switched in the SSB filter then signals dropped to almost nothing. OK, problem in the filter, so I got out some wire and a cap and was jumping the end of the SSB filter chain with the middle (and it did seem there was a problem in the second half..) Then without thinking I jumpered the first third of the chain at CD to the xtal output jack at P3/J10 neatly bypassing the step-down of T2 and slamming some nice voltage onto the main board and, I assume, into the IF amp. Signals were very loud for a moment though! Now all the audio is gone in all modes -- CW, SSB..ack! Is it worth banging around trying to chase this, or shall I just embrace my shame and send the whole mess off to Elecraft? -- Ward a little knowledge is a dangerous thing / KG6HAF ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] KPA100 Tightening the finals...
Just finished the KNB2 for my K2 (a birthday present from the in-laws -- yea!) and while I was inside the K2 to install it I tightened up the screws on the KPA100 finals per Elecraft's recommendation, since I've been using the radio for about 6 months now and this was probably overdue. They all took a little snugging up, maybe a little less than 1/8 turn. My question is: will they stay tight now for all time? Or do I have to check them now and then? What's the theory on the thermal cycling here and how it effects these screws?
