Now that I've had my IC-7000 for about six weeks; and repaired a fault in the pre-driver stage; and had several fine QSOs with this wonderful box of magic, I thought it was time to plug in the microphone and try it out.

It was immediately apparent that the PTT switch (with the red button) was operating intermittently.? This was confirmed by direct testing of the switch using a multi-meter.



At the time, I hadn't seen this Topic.? So I was very pleased, and a bit surprised, to find replacement switches on eBay.? Indeed, I found several suppliers of suitable switches.? ?This is not a recommendation, but I bought ten of the 6 x 6 x 5 mm right angle PCB switches advertised at:

I have no idea whether these switches are 'sealed' types.? ?But, for under ?5 for ten switches, this seemed like a very good deal, providing loads of spares for the future!? The first switch I tested worked fine, with a nice positive action.? So I soldered it in place.



Job done!
