Those Banana Mics sound like poo!

You want it? It is in pretty good shape and I unsoldered the wires from
their connection points, nothing was cut. I removed it today when I
installed a mic Jack in the side of the Chassis, where the factory left
a hole for one. ;)

Got anything to trade?

Bow that Banana mike was a great Mike but a D-104 amplified would serve
you better...If you don't want the banana and if it is chrome in good
shape I would love to buy it from you...I collect great mikes...

Thanks  Bob W1PE Dallas

Hey all,

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.

But I know this thing has to have some audio bandwidth bottlenecks.

Has anyone ever used one on the air?

The schematic is here:

For Starters, I think C24 needs to be increased to .22uf, to let some
low end through.

Any other suggestions?
