[1000mp] 1000MP Audio in Speaker on TX

Hi Graham - tnx for reply.
MP is the DC version and yes is has got worse over time.
It also makes no difference if you use the internal and external speaker.(For info, my external unit is fully filtered).

The rig is at Castle Electronic and they say that Yaesu are aware of the problem but no fix is available.Geoff at Castle has been very helpful and has offered to try and fix it, but says it could take quite a few hours as this would be their first attempt at this problem and could not guarantee a remedy, so at £50 an hour or so i could end up paying £200+ for nothing and even Geoff at Castle suggested this was not the best route.He has offered to supply me a circuit diagram that will mute the speaker, so at least this can be done at my own leisure without huge expense.

I think i'll try this with view to upgrading to a MK5 which i now understand doesn't suffer from this.
Thanks for the info

PS - Am still baffled that no one has come across this before, even now you are the only one to reply. Geoff has said that he's had quite a few enquiries with the same problem.
