JR DSX9 - Hissing sound from the back module

[acurusaragon]

HI guys,

I just bought the 2.4Gh JR DSX9 ..

The concern is that when I turn on the TX ... after the led on the module at the back turn to green ... there is some hissing sound that came from it (the module) .....

Is this normal for all 2.4Ghz radio ? i meant the hissing sound.....

All advise are much appreciated .

THanks

Most people say it is more of a buzz. But on 2.4 GHz the duty cycle for the actual transmit is only 10%. So you are hearing the RF deck powering up and down.

So I guess the buzzing sound is normal then ... thanks man ... I will now on to my new toy :)

Cheers.
