Keyup Delay Timer:

The keyup delay timer is used to keep short noise bursts that open the receiver’s squelch from

keying up the repeater. It can also keep people from kerchunking the repeater. When enabled, it

makes the controller totally ignore keyups shorter than the length of this timer (the rest of this

explanation will assume ½ second). If the receiver is keyed for longer than ½ second, the first ½

second will be ignored, then it will respond normally, bringing up the transmitter, triggering the ID

system, etc. To keep every keyup from being delayed, the keyup delay is automatically disabled

while the repeater is being used. It is only re-enabled when the repeater is not used for a default of

60 seconds (see timers 194..201). If this timer is set to zero (the default), the keyup delay is

disabled. A typical setting would be 50, which is ½ second.

Wind Speed Timer:

This timer is used to help determine the wind speed indicated by an anemometer. The number of

pulses counted during the length of this timer becomes the pseudo-analog value. For more

information, see command 109.

076 Wind Speed Timer 2.26 sec (226)

Word Too Long Timer:

There is no need to change this timer! It is used to ensure that even if the voice synthesizer messes

up, that it will not cause the controller to leave a transmitter keyed. If a word takes longer than this

timer, it will be truncated and the controller will go on to the next word.
