Because of I set something wrong(maybe), My GP300 have a problem...

When I turn it on and key it the first time, It got a continuous beep sound but without any transmission. And I de-key it and key it again, it's transmission become fine. But when I leave it alone for a while, and key it again, it become the same as the first time.

I had change something in the "Alignment menu" and may make it wrong.
Anyone can help me??? Thanks!!!

I find that the Power output become really LOW and can receive it around 15 feet... Please help my GP300!!!

OK, item 1, sounds like you have the "Forced Monitor" enabled. The beep lets you know you didnot Monitor first, enables carrier squelch or monitor. The second PTT is normal operation .

Item 2: Bad antenna contact, incorrect antenna, or the power settings have been fubared.

It is also posible if the radio receives OK, that the control transistor blew out, happens very often due to incorrect antenna, or bad antenna contact.

what frequency do you have programmed in TX and RX and if you are using a subtone , what is it?
what is the highest and lowest frequency the radio is able to have?
has the accessroies socket been changed?
read the radio and look at the alert settings.

I will try it tonight, but did anyone have the programming manual for GP300? Or did it have any default setting for it?
My GP300 Model is: P93YPC00C2AA
Because I don't really understand the setting inside the software.

There really isn't a default setting in the programming manual for the service side of the RSS. The settings you see for power output, deviation, reference oscillator, etc, are all "soft pots" and you need a service monitor to adjust these settings.

Hope that is helpful
