[Elecraft] K2 curious problems
I'm looking for some help with my K2 (SN 5165) that has developed the following problems: 1. Even after pushing the A=B vfo control, B does not track with the A vfo but remains where it was when the A=B was pushed. 2. When I turn on the K2 the audio initially sounds fine but after a variable interval it becomes distorted and muffled. The strange thing is that if I cycle the power off and on the audio returns to normal. This doesn't affect the transmitter. The voltages on the 5v and 8v lines measure ok. I'm not sure if this is a problem with the MCU or with a relay that needs to reset. Is this a problem that others have noticed? I'm at a loss as to how to track this down.

[Elecraft] Elecraft Wish List
How about making the K3 an honest to goodness kit like the K2? Elecraft started out as a kit company but lately seems to be drifting away from the concept. Assembling modules is just not the same for me. The building of the kit was the reason I chose the K2 and there are over 7000 other hams out there who felt the same.

[Elecraft] Upgrading K2
The KPA100 and KAT100/1 will play together with not other upgrades. However, if you install the amplifier and tuner in a separate enclosure (KAT100/2), you need to add the KIO2 to your basic K2 to provide control signals.

[Elecraft] qrp balun
Ed, I built http://file:///Users/william/Downloads/Balun%20Manual%20-%20final-2.pdf and it works just fine. It comes from the NJQRP webpage. I've used it at 5 watts but the author says that he ran it up to 100 watts without heating.

[Elecraft] Kaf2 anti ringing mod
I have seen mention of an anti ringing modification for the kaf2 that was published several years ago by ki6wx. Has anyone done this mod or know where I can find the details? The link often mentioned no longer works.

[Elecraft] K2 alignment and test, part III problem
I just finished up the RF board and am proceeding to the testing. Much to my dismay, however, I got no power output when I tried to adjust the 40 m BPF. I'm getting 13.5 v to all of the collectors and I pull 220 ma on receive and 420 ma on tune. The RF detector resistors and diode are correct and the transformers look good. With an RF probe I get zero volts on the xmit mixer output (U10 pin 4). So I went back further and did some basic voltage checks and found some interesting results. The key down voltage on the anode of D7 is 0 v when it should be 8 v. The anode voltage on D6 is 0.645 v on key down instead of 0 v. On receive it is 8v. I'm having some trouble getting my head around how this relates to my lack of output power. Another symptom I'm having is that the menu and display controls cease to function when I plug in a straight key. But they work ok with a paddle attached. I feel a headache starting. Any suggestions on how to proceed?
