<p>[QUOTE="Night Stalker10, post: 11657288, member: 200038"]Okay, have you tried the PA to see if you get audio through the internal speaker? Be sure and turn the mic gain way down before you key the Mic. Then as you talk, slowly bring the mic gain up and hopefully you will hear yourself talk. If this works , then the mic and audio section is good. It's still possible there's a cold solder joint somewhere or the TX final is bad. Tnx for the picture, that sure helps to see what it's doing.</p><p><br /></p><p>I'm not sure the TX final is bad just yet. It sounds like from your first post that you were able to calibrate the internal swr meter, which sounds like you are getting RF power out. But how much we don't know without a power meter.[/QUOTE]</p><p><br /></p>
