Ron, Vintage radios were made with regular leaded solder so they don't have that problem (unless you repair them with lead free solder.) It's the new rigs that I'm concerned about. Tin whisker growth under surface mount components would be very difficult to detect and remove. So keep your vintage Drake radios operational and you won't be without a rig if the new one fails.

For those unfamiliar, the new lead free solder often has a higher tin content and can causes tin whisker growth issues. Who knows when it might strike your beloved solid state or hybrid vintage radio. Maybe we should all return to hollow state :-) http://www.vintage-radio.info/whiskers/ Totally amazing IMO. 73, Ron WD8SBB _______________________________________________ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist _______________________________________________ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
