W4RT One Big Punch help

[K3BAK]

I had W4RT install the one big punch in my ft-857d microphone. I normally set my mic gain at 70 and my audio reports are good. I turned the gain down to 13 and turned the processor off to use it with the OBP in order to not overdrive. It worked fine for a few months and now my audio is unintelligible. Anyone have this same issue or any ideas?

Anyone!!!

Maybe I'm missing something here, but it seems to me the thing to do is call W4RT and ask him about it.

Mine works wonderfully. I would suggest a call or email to them.

How the W4RT One Big Punch (OBP) works.

One BIG Punch (OBP) is a custom add-on accessory for the Yaesu MH-31 microphone that is used with the FT-817(ND), FT-847, FT-857(D), and FT-897(D). The OBP is an AF-based speech compressor specifically configured to provide remarkable increase in talk power while maintaining good audio quality (articulation) for communication purposes.

Thanks for the reply. I emailed them, still waiting a reply. Just was curious if anyone had any issues with the OBP.

They were probably pretty busy the last few days as they had a booth at the Huntsville Hamfest.

You can't call them...no phone...good luck getting a reply via email...busy or not, they never seem to have time to return emails...however, they will be more than happy to take your money.  :-)

Hi,

Assuming that the problem is actually due to the modified microphone (can you check with another mic ?). And that it's not due to RF in the shack (can you check with a dummy load ?)

It's a relatively simple circuit to fault-find.

The device data sheet and sample circuits can be found here.

Personally, I'd open up the microphone housing and see if any wires have come adrift.
