T1 Tuner Kit Control Board final check issues

It's really hard to beat a Simpson 260 or Triplett 630.

Subject: [Elecraft] New KX2 VFO knob wobble.
Message-ID:<[hidden email]>
Content-Type: text/plain; charset=utf-8

Hi, new KX2 owner here. My new KX2 was delivered on May 10, and had a significant wobble in the VFO knob.? After carefully removing the knob, I discovered that the majority of the wobble was due to the loose fit between the outer structure of the control and the panel opening.? I have temporarily carefully shimmed the gap with some 24 gauge wire, but I believe that a more permanent solution would be a locknut on the control housing which I do not have.? ?With this temporary fix in place, the tuning knob works well.? I contacted Elecraft Support on May 11 or 12 regarding this situation, but have not received a reply.? Does anyone have any suggestions for a more permanent fix?? Thank you in advance.?

Hi Don,

Yeah, I don?t often perform measurements on components already installed in a circuit, so the behaviour was confusing.  I thought I bought a nice DMM but I guess it was just a fluke?

Anyway, I got it finished and everything is operational, now just have to wait for the IC-705 interface cable!

   Thanks and 73,

Erik,

Yes, using auto ranging on the DMM can cause false readings.  Try to set the fixed range a bit above the highest expected resistance for the best results.  It all depends on the voltage the DMM applies to the circuit.  Too high a voltage can make ICs and transistors conduct causing a low reading.

73,
