My mobile 7K refused to transmit a couple of days ago. It had worked fine
the night before. I swapped mic's and it worked. Reflowing the solder joints
on the PTT switch and RJ-45 connector again didn't help.
I pulled the switch out and confirmed in would only occasionally make
contact no matter how it was pushed.
Mouser normally carries an Alps switch that I have used previously, but
they were out of stock until 11/22/10. So I ordered a couple from Icom
Bellevue for $2.79 each. Mouser sells them for $0.30.
The switches are rated for 200,000 cycles by Alps. I don't think I've come
close to that in 4 years, especially since I use a headset mic or boom mic
and foot switch much of the time.
