// from 100ms up to 1 sec in 100ms steps. Values are drawn from samples going from ADC
|

// so it is better to use Unsquelched output in radio to provide much more randomness
|

//After waiting time declared above ParaTNC will check DCD (Data Carrier Detect) flag, which works as some
|
||||
//kind of semaphore. If radio channel is not occupied by any other transmission TX will be keyed up immediately,
|
||||
//otherwise software will wait for clear conditions.
|
||||
|
||||
// Few IMPORTANT hints about setting transmit delay properly.
|
||||
//
|
||||
// Transmit delay is key parameter to maintain RF network free from packet losses and collisions. If your station will be
|
||||
// installed on tall object, without any other digi's close to it, you can set _DELAY_BASE to very low value and disable
|
||||
// _RANDOM_DELAY. If you wanna rather auxiliary station, witch should only fill gap in RF coverage in small area, then
|
||||
// _DELAY_BASE parameter should be not less than 12 (600msec), the smallest range the higher _DELAY_BASE should be.
|
||||
// Additionally for gapfillers (auxiliary stations) _RANDOM_DELAY schould be enabled.
|
||||
//
|
||||
// This delay will ensure that while other station will be transmitting repeated packets from mobile, Yours will keep
|
||||
// always quiet and won't jam RF network. This greatly improve DCD based access to channel. Various controllers uses
|
||||
// various lenght of preamble, some of them produce signal which might be impossible to decode by ParaTNC, so DCD
|
||||
// is only one part of effective multiaccess to medium.
|
||||

||||

||||
