Hands-free mic for radios

You may remember that I wanted to get a hands-free microphone for my Yaesu FTM-400XDE from Martin Lynch & Sons while at the National Hamfest this year, only to discover they had none with them as last year no one bought them, so I have ordered one, at last, off their website with wiring for the Yaesu radios that have the same mic socket as mine, my plan is that as I have booked Friday afternoon off work is that I can begin fitting it to my car and perhaps tidy up the control head cable as well as the cable tie mounts that hold that on had come off during the summer months when the temperature inside the car reached high levels enough to soften the adhesive on the cable tie mounts, important considering the cable is starting to foul the passenger side airbag which could prove dangerous if I have a crash with a front seat passenger on board.

The microphone mounts to the hinge of the sun visor with a cable running to a control box that mounts to the gear stick (though this does not work in automatic cars very well), it has a toggle switch for PTT and up/down buttons (which do not work with the FTM-400), and should time out after 3 minutes TX should it be left on by mistake, this means I don't have to hold a microphone and only have to take my hand off the wheel to key up and again when I have finished speaking to go back to RX.

This would also leave me without direct DTMF entry unless that can be done from the control panel, I'd need to read the manual to find out if this is possible, alternatively I could find a way to keep both mics plugged into the radio and allow a way to switch between them.

Though I do like to operate mobile, the majority of the roads around here don't lend themselves to the mobile operator due to lots of bends and roundabouts, and I consider road safety to be priority number one when driving, if I cannot drive and operate my radio safely I won't operate the radio at all.

On a side note, I should have been attending this year's Bishop Auckland rally at Spennymoor, however it is early this year (today) and I have not been paid, so it looks like the next rally I will be at will be either Ripon or Blackpool next year, whichever comes first.

Due to past abuse and the ongoing issues that left me little choice to reduce time on twitter and IRC I have taken the decision to keep comments disabled indefinitely, apologies for this
