Hello!

I am new to this forum and to radios. I am helping an organisation apply for a radio license in a central asian country and I am having problems knowing how to fill in the license. We have a Motorola Radius GM300 base station at our office and I need to provide the following information, which I have had no luck in discovering as I have searched the internet.

TRANSMITTER EQUIPMENT:
Class of Emission:
Transmiter output power (W):
Type of Power Delivered to Antenna: ___ X ___ Y ___ Z
Power Delivered to Antenna (W):
Max. Radiated Power (W):
Type of Radiated Power: ___ EIRP ___ ERP ___ EMRP
Duplex type: ___ S1 ___ S2 ___ D

Maybe this is the wrong place to ask these questions but if someone could direct me where I could get this information, I would be most appreciative. If there is more information I need to provide to get help, please let me know. Thank you for any help you can give.

Sincerely,

Dave Keller

Dave,

Most of the information that you're requesting depends at least in part on the definitions contained in the radio laws of the central asian country in which you're applying for a license. For example, in the US, the FCC is the licensing authority, and their rules and regulations define emission types(which may not be the same as those defined in the Asian country). Such things as ERP, EIRP are universal engineering definitions that mean the same thing the world over - transmitter power minus feedline loss plus antenna gain over a dipole is ERP, and EIRP is transmitter power minus feedline loss plus antenna gain ref isotropic, etc.
In short, you would be well advised to consult the radio rules in the appropriate Asian country for full definitions of the parameters they're asking for. With these definitions and the published specs for the GM300 in hand, then you can properly complete the application.

Thank you,Al. I will investigate further on this side.
