<DIV><FONT size=2 face=Arial>Back in December I posted a thread on an
alternative to adjusting the SB-101 100hz capacitor to 'zero' beat it to the
aproppiate frequency. We went through a lot of ideas. I ended up
taking a rig with a digital readout and pluging it into a dummy load and setting
it to 5 watts and trying to adjust the 100 hz capacitor from there. It
came pretty close, but not close enough to adjust the dial as I changed bands to
set the pointer to zero.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>As I was sitting one night listening to the old man
international single sideband net, I sat and tweeked the tuning dial so 90% of
the people transmitting didn't sound like lurch or micky mouse. I had been
doing this for about a week everytime I tuned into the net. </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Then it hit me. I had a an almost perfect
frequency reference. If the voices were sounding "natural" for 90% of the
people on the net I must be pretty close if not dead on. So I slid the
marker over the frequency that the net was on and didn't move it.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I set the sb-101 to cal and turned the tuneing dial
over to zero and I heard the tone. I was in lowerside band (you can be in
upper side band) and adjusted the capictor until I no longer heard the
tone. I turned it to upper side band and adjusted the capacitor out and
back in until I no longer heard the tone. I switch back and forth between
upper and lower sideband until I got the capacitor 'centered' inbetween the two
so I didn't hear the tone in either.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I turned back to the net and it was still dead on..
shut it down and let it cool for a day and turned to a net on a different band
and set my dal using the new cal settings.. the dial was dead on on 15 meters,
40 meters and 80 meters.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>If someone runs into the problem and wants to tweek
the crystal adjustment without using the steps in the manual, I hope this
helps.</FONT></DIV>
