[Elecraft] Audio dropouts while tuning in K3 SubRX

I noticed the same short audio dropout on the SubRx only (not the main) while
operating the CQ160 SB contest at home and the ARRL DX Phone contest at W3LPL. I
don't recall seeing this problem being reported until Brett mentioned it.  I
noticed the clicks occurring on 160M at the frequency transitions every 5 KHz:
1816.449 to .450
1821.449      " 
1826.449      " 
1831.449      "
When tuning some freqs above 1900 KHz the spacing changed to 6 KHz:
1937.449 to .450
1943.449       "
1949.449       "
1955.449       "
1961.449       "

It's not a severe problem but certainly was annoying hearing the clicks when
certain freqs were passed while hunting the 160 Meter band for mults.
I was using the new Beta firmware. Will check out the previous version when I
get a chance to see if it was there and not previously noticed.

What is the story behind the audio breaks when tuning in the sub rx...
 Right now I get a break anytime I tune from and to the following
frequencies:

7.060.99 <-> 7.061
7.069.99 <-> 7.070
7.078.99 <-> 7.079
7.085.99 <-> 7.086
7.086.99 <-> 7.087

There are more but thats an example of them...  Its just a short blank pause in
audio whenever I make those transitions (in either direction I hear the pause).
