Continuation of previous post, accidentally hit the "post button":
some serious family health issues. Recently I have started taking lessons again and started to use my Flycom helmet with a PTT switch while practicing "balancing on the mains." Unfortunately, I find I am getting a high pitched loud tone whenever I push the PTT switch, which makes communication impossible. Another gyro pilot mentioned to me that he had issues with using a PTT with his Flycom helmet, and they were resolved after he purchased a Flycom PTT. So I ordered a Flycom PTT, and still get the same problem. I am using an Icom A6 radio. Furthermore, both PTT switches work fine with my Sigtronics headset. This seems to me to indicate that the problem is with the helmet. I have contacted Jade Hawkes at Flycom, but as of yet, have received no reply.
Anyone else had a similar problem with a Flycom helmet, or any other helmet, and if so, how did you resolve it?
BTW, if I use the PTT button in the radio, everything works just fine.
Thanks,
Russ
