Re: Wall warts can be fatal to QMX :-(
¿ªÔÆÌåÓýI have followed email responses like this for years and have learned by observation. ?I do not use wall warts in ham radio, at least any wall warts made after about 1990 as most are junk. There is a reason linear wall warts like those that Yaesu and Icom sell are heavy. ?They have a transformer and other controlling circuits in them. ?Batteries are low cost in comparison to repairing a blown radio and the Drok battery controllers are cheap and work well. ? I have built many of Hans radios over the years ever since he started selling his kits and have never blown a single one. Be careful, use your voltmeter, and avoid any wall warts. ?Also beware of the voltage plugs. They may look good and feel good when you plug them in to your favorite radio but poor contacts have blown many a radio. ?Read and learn. Also remember my story about the battery purchased at a swap¡. with the RED price tag still fastened to the NEGATIVE battery post¡. late at night, tired, and testing a radio just once more before going to bed. ?Mislabelled battery smoke smells just as bad as any other electronic smoke. ?The only good smoke is made by heating rosin while kit building. Be the REASON someone smiles today. Dave K8WPE On Nov 16, 2024, at 9:57?AM, spaine via groups.io <spaine@...> wrote:
