The "Connected to Internet" check box is an artifact from an earlier
version and no longer has any function.

[CTRL+B] will send a complete text file over a RF link. Two limiting
factors are the transmit timer in the radio and the "QST size
limit" (See Preferences>Chat>QST size limit).

D-RATS can send e-mail to any internet e-mail address. To route it
through Winlink, use the WL2K prefix (e.g.
WL2K:rumplestiltskin at gmail.com).

Messages, Chat and files can be transfered over a D-STAR radio link.

There is not an iPad version of D-RATS, however some have used their
iPad to remote access their Desktop machines running D-RATS.

D-STAR voice       = 3600bps
sync bits                = 300bps
low speed data    = 900bps
total                      = 4800bps
The transmit message on the D-STAR radios uses the low speed data
portion of the data stream, so turn it off to increase D-RATS
throughput. Both voice and data run concurrently.

The windows version of D-RATS is known to consume a great number of CPU
cycles. This issue is currently under study.

Frequencies: 145.67 is used as a National D-STAR simplex frequency in
many parts of the U.S. This band segment is also heavily populated by
packet operations and Winlink nodes. My group has chosen 144.91 and
144.93 as they are in the segment designated as weak signal and
experimental. Use your local band plan as a guide.
