Bow, I would change out the following capacitors to .1 uF (or .22 if you like; there won't be much diffeence): C24, C31 and C35. C24 is key, while C's 31 and 35 will also affect receive audio (more lows). While your at it, remove resistor R48, or make it much smaller. It controls power output.
Finally, you can either leave R22 as is, or change it out for a 10 megohms. 10 megohms is required when using an un-amplified D104. Otherwise, that 4.7 megohms is satisfactory for most Hi-Z mics. ---------------------------------------------------------------------- Bow wrote: Has anyone here ever played with a Johnson Messenger (or Messenger Two) CB on 10 meters? I am looking for suggestions on how to get better sounding audio out of the one I have. The Hardwired Crystal "Banana" microphone is coming off ASAP and I plan on inputting audio from my rack gear, or using a more modern dynamic microphone. ______________________________________________________________ AMRadio mailing list List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Partner Website: http://www.amfone.net Help: http://mailman.qth.net/mmfaq.html Post: mailto:[email protected] To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body.
