KX 1 VFO noise

k4elv
I sent an email to the group yesterday and received a reply stating that the mailbox was full??  So, I'll resend my request for help.  
I haven't used my KX1 since I completed assembly a few weeks ago. At that time
all seemed well. In preparation for a trip I got the unit out to test it. I
found that as the VFO was tuned a "popping or clicking" noise is heard each
time the display moves. It sounds like statis from a counter?? I seem to recall seeing this mentioned by the group
but I can't find a reference. Any ideas? External battery voltage is
approximately 12.4 volts. Internal batteries are low, but I still hear the sound.  Thanks,
Mike K4ELV

   I'm not sure this is the same noise you are hearing...

While the display on my KX1 is lit, I hear a static like noise.  
Reducing the brightness of the display to about half cuts
out all the noise.  My guess is I am hearing the digital signal that
strobes the multiplexed LED display.  By reducing the
brightness the noise is too low to be a problem.
