You may want to use two low profile sockets if you have a couple in your junk box. Put the firmware chip in one and solder the broken lead to the socket. Then solder the second socket to the PCB and install the first. This allows you to replace the firmware chip if necessary. >73, >Don W3FPR > >> -----Original Message----- >> Question for Don, Jim or anyone with experience in this. >> >> If I completely removed the ruined 28pin socket and am able to >> solder a little wire onto the broken pin of U1, would it work to >> carefully solder U1 directly to the circuit board without using >> the low profile 28 pin socket? >> >> I suspect that all my problems stem from this error I made early >> on and was just lucky that it has worked for almost 6 mos. >> >> Thanks for all your help again, >> >> Bob >> >> >-- >No virus found in this outgoing message. >Checked by AVG Free Edition. >Version: 7.5.432 / Virus Database: 268.15.27/602 - Release Date: 12/25/2006 >10:19 AM > >_______________________________________________ >Elecraft mailing list >Post to: Elecraft@mailman.qth.net >You must be a subscriber to post to the list. >Subscriber Info (Addr.
