Hi all
I keep getting reports of quite severe distortion when I use my Zbitx in SSB mode, is it the fact that I'm only using the internal mic, ( reasonable signal reports for a QRP but unintelligible audio) giving it a bit more gain either goes from very little output to distortion, doesn't seem to be a right level, audio level meter is very jumpy too, do I have to adjust any other settings. FT8 seems to work fine and I'm getting output when I try 2tone tests. I'm only using 18650s so is it perhaps wanting a proper 9v supply. Any help would be appreciated. Martin? |
¿ªÔÆÌåÓýI tried the internal mic and with settings above 50 it tends to oscillate ¨C looks like RF feedback. At 60 it oscillates steady, at 40 it looks better but no idea how it sounds. If I¡¯m ever going to use it in SSB, I¡¯ll use an external mic. ? 73 Frank PA3CNO ? ? Van: [email protected] <[email protected]> Namens Martin Howard via groups.io ?
