I assume you meant "quite" as opposed to "quiet" (but with radio it is best to specify).
Also assuming you are talking about a scanner. The number of TG's programmed has little to do with the scanning speed (see the one exception* mentioned below). The number of frequencies is only a factor in how fast the scanner finds the control channel on initial entry into the bank or system (DMA radios), again assuming you are scanning more than one bank or system. For example if the first frequency in the bank/system is the control channel, then the radio will lock on to it, spend the amount of time you have programmed (or the scanner is designed to do) to check for activity, then it moves on; makes no difference if it is a Motorola or EDACS. Of course if the CCh frequency is near the end of the bank/system list then it will take just a bit longer, but in today's scanners that should not be a noticeable difference.
With that explanation consider these possibilities if you notice a significant difference between systems.
- One of the CCh's is not being picked up at all.
- The scanner is not programmed correctly for either the EDACS or Motorola system. In other words the CCh frequency is programmed, but not the right type; e.g., EDACS Standard (wide) programmed where the CCh is EDACS Narrow.
- The "Hold" times are programmed differently for the each system (this would depend on brand and model of scanner).
- *One system has a lot of activity on it but for TG's that you do not have programmed and/or are ignoring, in comparison to the other which has little or no activity. An idle CCh (no channel grants) is passed through much more quickly as the scanner does not have to compare what it is hearing with your list of acceptable TG's.
When asking such questions, it is always helpful to supply the scanner model, this aids in more specific answers. :wink:
