4.1.15 TX Data Delay
This parameter controls the delay between the time the transmitter is turned on and the start of the
transmit preamble for POCSAG pages. The delay is given in milliseconds.
4.1.16 TX Stream Delay
The TX STREAM DELAY puts small pauses between pages in order to pace the transmission of
discreet pages. This delay helps slower pagers (generally broadband types) to see all the page traffic,
analyze it and recognize those pages addressed to it.
4.1.17 Shift CPU Clock
In rare cases, the desired receive frequency may coincide with computer noise generated by the
internal CPU. This option enables the user to change the CPU's timing, which may shift the CPU's
computer noise away from the desired receive frequency.
4.1.18 CW Identification Call Sign
In many cases, the rules and regulations under which the OSMAC Base is licensed by the
government require that the station's Call Sign be transmitted at regular intervals for identification
purposes using Morse Code. The OSMAC Base sends the Call Sign (with CTCSS turned off so the
mobile radio users won't hear it) every 10 minutes if the Call Sign has been programmed. This feature
is disabled when the unit comes from the factory.
To enable this feature, press 5 from the main configuration menu. At the prompt, enter your station's
Call Sign from your license as follows:
Numbers are entered directly from the keypad.
Letters and other special symbols are entered from the keypad by pressing the arrow keys.
Alternatively, an external keyboard may be used to enter alphanumeric characters directly as
typed.
Press the F2 key to accept the displayed letter when using the unit's keypad or to enter a "space"
character which is displayed as a "_" and results in a pause in the Morse Code.
Press the DEL key to delete errors or to disable CW Identification by totally clearing the display.
Press the F1 or "-" key to accept the Call Sign and exit the menu.
Up to 19 characters may be contained in the CW Identification string.
