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.? Dave, K8RXB?Sent from my Galaxy

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!

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.

[Elecraft] OT Need copy of "Antenna Zoning and the Radio, Amateur " second edition

[Bob McGraw]

Be sure and check you local and state codes.  They will vary from city to city 
and state to state. In most cases a visit to your local codes office will 
inform you of the requirements.

Good luck with the tower project.

Re: [Elecraft] K2 rotary encoder

[Josh Gibbs]

Thank you Don. Confirmed I have 7.8V at anode of D6 and zero at anode of D7
in RX.

U3 is a TPIC6B595N which is in stock at the usual online electronics
retailers and very inexpensive.

Re: [Elecraft] K2 rotary encoder

[Don Wilhelm]

Josh,

Your investigation is "spot on" and I would normally recommend replacing 
Front Panel U3.  It is possible for it to have one bad input and is 
quite static sensitive.


But first, check that 8R and 8T signal lines are working properly.  An 
easy place to check is at the anodes of RF Board D6 and D7.
The anode of D6 should be near 8 volts during receive and the anode of 
D7 should be close to zero.

That situation will reverse during transmit.

If you find 8R and 8T are on at the same time, that could be reason for 
the problem.
If you have a problem with those signal lines, check back on the control 
board at Q1, Q2, Q3 and Q4 to determine where the problem might be.

Don W3FPR

All other functions appear to be working normally, but the rotary encoder
is disabled.

If I ground the V- pin (via 100 ohm resistor) the encoder comes to life and
functions normally.

I have verified good continuity between encoder V- and pin 14 of U3.

In the manual it says that the MCU can disable the encoder under certain
operating conditions. What might those conditions be? One thought I have is
that the MCU is disabling it for some reason.

My current plan is to try replacing U3. All other functions of U3 appear to
be working.

Any troubleshooting advice would be appreciated. Thanks for reading.

[Elecraft] K2 rotary encoder

[Josh Gibbs]

My K2 (SN: 4073) suffered a sudden problem yesterday. I didn't notice
anything happening - one minute it was working normally and the next the
VFO knob stopped working.

All other functions appear to be working normally, but the rotary encoder
is disabled.

If I ground the V- pin (via 100 ohm resistor) the encoder comes to life and
functions normally.

I have verified good continuity between encoder V- and pin 14 of U3.

In the manual it says that the MCU can disable the encoder under certain
operating conditions. What might those conditions be? One thought I have is
that the MCU is disabling it for some reason.

Re: [Elecraft] K3 preamp upgrade board?

[Hisashi T Fujinaka]

All the replies are coming straight to me, so I figured I'd follow up to
myself here.

Turns out the KXV3B contains the preamp I was thinking of, and I
pre-ordered one. It's $260 and when I was buying all the other updates I
figured I'd wait for the sunspot cycle to start back up before I spent
that much on a preamp (I already have the KXV3).

I pre-ordered one. Now I can pretend my K4 and the KXV3B are in a race.

finally ships. :)

[Elecraft] K4/10 & KXPA100 ?

[Phil Hystad via Elecraft]

I currently own both the KXPA100 and the KPA500 amplifiers.  If I were to buy a 
K4/10, I am assuming that it would be fully functional (all interface features) 
with either of these amplifiers.

Question: are there any functional limitations with K4/10 operation of either 
of these amplifiers?


Also, I would like to know pros/cons on the following configuration:

   K4/10  —>  KXPA100  —>  KPA500

Thanks,
