<DIV><FONT color=#000000 size=2>In the 1978 issue of the ARRL Hints and Kinks on
page 37 there is a simple fix, I did it years ago to cure the same
problem. The article is called "Improved Recovery for Heathkit
Transceivers and Modification for the SB200 Linear Amp" I do not know
anything about the 2nd part of the article on Modifications for the SB200 Linear
Amp, but it is unrelated to the first part of the article. If you or
anyone else needs a copy send me a EMail and I will scan it in and send it to
you. </FONT></DIV>

<DIV><FONT color=#000000 size=2>Anyone have any ideas on this
problem??</FONT></DIV>
<DIV><FONT color=#000000 size=2>After holding the mic button for about 30
seconds (or transmitting), the receiver comes back with the S meter at about
+40db...as if the RF gain control were turned up. </FONT></DIV>
<DIV><FONT color=#000000 size=2>It slowly drops back to normal in about 10
to 20 seconds or so.</FONT></DIV>
<DIV><FONT color=#000000 size=2>Shorter transmissions do not exhibit this
problem.</FONT></DIV>
<DIV><FONT color=#000000 size=2>I tried replacing several tubes with no
results.(IFs, AVC, RF etc)</FONT></DIV>
<DIV><FONT color=#000000 size=2>Any ideas???</FONT></DIV>
