<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt">I thought I would check here to see if anyone beside myself had run into this problem: I am
working on a friend's HW-101 which he recently bought at a garage sale for $50.00 with an
HP-23 and a Heathkit speaker.</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt"><br />
</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt">The HW-101 was extremely dirty, not having been used for some time, but cleaned up well,
and was apparently very well-built.</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt"><br />
</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt">The problem is that after the rig has been on for a bit, the VFO quits. Completely.</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt"><br />
</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt">I hooked my Tek 2467B scope to the output coax and although when cold, the output is
good and is a pure-looking sine wave, within about 15 minutes at the longest, the output
amplitude begin to fall, then suddenly completely disappears.</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt"><br />
</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt">I have a "spare" HW-101 VFO here which I "clip-leaded" into place, and with that one in
operation, the rig works exactly as it should. It even appears to be properly aligned.</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt"><br />
</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt">So...has anyone else here experienced such an issue with an HW-101 VFO, and if so, what
did you discover?</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt"><br />
</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt">I'm going to remove the bad VFO sometime next week.</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt"><br />
</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt">I suspect I will find a bad solder joint in it somewhere, but I am also suspicious of a bad
component. But which one?</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt"><br />
</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt">Also, are replacement Jackson ball-drives still available? These are a bit rough.</span></font></div>
<div align="left"><font face="Arial" size="2"><span style=" font-size:10pt"><br />
