<DIV>KE5ZB is right, and yes the flickering last digit was annoying. Even when
not tuning, if the last digit</DIV>
<DIV>was say '4' but close to '5' it will change back and forth rapidly. </DIV>
<DIV> </DIV>
<DIV>There was a mod out there as I recall that slowed the update rate of the
digital display so that</DIV>
<DIV>the flicker was less. Modern frequency counters have logic added to
minimize this last digit jitter.</DIV>

typo - on the original SB-104 the 100 Hz button turned off the last
frequency display digit, after the decimal point. Evidently the design people
at Heathkit at first thought that some hams would be bothered by watching that
digit rapidly change while tuning. I seem to recall that the field 104A
upgrade kit, among other things, converted that button to select the optional
400 Hz CW filter, and the last display digit was left turned on all the
time.<BR><BR>73<BR>John KE5ZB<BR><BR><BR>On 5/31/2013 7:29 AM,
