Note that these settings apply when everyone on the channel is running the new
protocol. This assumes that all stations on the channel have both DWait and
RESPtime set to 0.
If you are running the new protocol on a channel where some of the stations have
long RESPtime delays, those stations will not be able to successfully
communicate with you after connecting. If you wish to communicate with these
stations you will have to set your FRACK timer to a number which is longer than
the other stations RESPtime delay.
Both DWait and RESPtime are meaningless in the context of the new protocol.
However, in this release both timers are still active and should be set to 0 when
using the new protocol.
Initial Parameter Settings Summary
The settings for use at 1200 baud on a VHF FM channel are:
ACKprior ON
SLots 3
DEAdtime 33
ACKTime 13
RESPtime 0 (If you require a nonzero value for this
parameter in order to prevent ACKing individual packets in a
MAXframe greater than 1 blast, your DCD circuit is not working.
Please get it fixed.)
DWait 0 (DWait should be set to 0 even if there are
digipeaters on the channel. The new system will not degrade the
performance of digipeaters on the channel because the ACKWAIT can
be used by the DIGI.)
MAXframe 1 - 7 depending on channel quality
FRACK 3
The settings to use for 300 baud work on a linear mode HF channel are:
ACKprior ON
SLots 3
