All of my Knightkit and Heathkit assembly manuals in the 60s instructed the same thing: make sure the wire/parts joint is solid mechanically before soldering.<div><br></div><div>73 de&nbsp;</div><div>Gene Smar AD3F&nbsp;<br><br><div id="ymail_android_signature">Sent from my Radio Shack TRS-80 model 100 laptop</div> <br> <blockquote style="margin: 0 0 20px 0;"> <div style="font-family:Roboto, sans-serif; color:#6D00F6;"> <div>On Sun, Jun 22, 2025 at 6:56 PM, Ron.K3PID</div><div>&lt;ron.k3pid@sbcglobal.net&gt; wrote:</div> </div> <div style="padding: 10px 0 0 20px; margin: 10px 0 0 0; border-left: 1px solid #6D00F6;"> <div id="yiv1411588941">

<div><font face="Arial">As I work on radios that are older than me ( 80) and I try to unsolder a wire from a post, I am reminded of what my shop teacher said in 1959 as I was building a power supply... He said if it isn't a good mechanical connection, it won't be a good solder joint.. Those folks who built radios for the war understood that for sure!</font></div>
