A similar symptom may be encountered<br /> with type II or hybird systems. The problem is due to an<br /> unavoidable delay when changing frequencies when keying up. &lt;/p&gt;<br /> <br /> &lt;p&gt;WORK AROUND : SAME AS SOLUTION, MAKE TX IDLE = TX ACTIVE<br /> FREQUENCY &lt;/p&gt;<br /> <br /> &lt;p&gt;Do not programm the Tx idle frequency to a value different<br /> than the active Tx frequency in trunked systems. &lt;/p&gt;<br /> <br /> &lt;p&gt;SOLUTION : THE R9.0 RSS WILL CONTAIN THE FOLLOWING HELP TEXT &lt;/p&gt;<br /> <br /> &lt;p&gt;NOTE: The actual channel keyup time (i.e., time for the<br /> station to switch from the Idle frequency to the channel transmit frequency),<br /> will be directly proportional to the frequency difference between<br /> the Tx Frequency and the Tx Idle Frequency. Certain applications<br /> (Trunking) require minimal delay between switching between these<br /> states. In Trunking configurations, make the Tx Idle frequency<br /> the same as the Tx Frequency . &lt;/p&gt;<br /> <br /> &lt;p&gt;This is an Informational Bulletin Only.
