Dan;
As you noted on another message thread, I've been able to get full VARA FM 'WIDE' throughput using a DRA-45 board with my IC-7100.
The key radio setting for 9600 bps packet or VARA FM WIDE is having 'Connectors > 9600bps Mode' set to 'ON'
The IC-7100 Full Manual states:
9600bps Mode (Default: OFF)
Connectors > 9600bps Mode (9600bps Mode)
Select whether to allow data transmission at 9600 bps,
or not on the [DATA2] socket.
? OFF: Disables data transmission at 9600 bps on the
[DATA2] socket. This is used for regular audio or
slower data transmission only.
? ON: Enables data transmission at 9600 bps on the
[DATA2] socket.
Connectors Set mode (Continued)
Also, on my IC-7100, 'Connectors > DATA MOD' is set to 'ACC', and 'Connectors >?VSEND Select' is set to 'OFF'. My radio's 'Connectors > DATA MOD Level' setting is at the default '50%' value.
With the above settings,?
your DRA-36 must be configured with the JU4 jumper in the 'B' (9600) position, so that the?audio input on the DRA-36 C-Media sound chip is connected to?receive audio delivered through the 9600 bps pin of the radio's DATA2 connector.
When you have your radio and DRA-36 properly configured, and adjusted, for 9600bps packet / VARA FM WIDE, you'll find you can leave the system in this configuration and make reliable connections with VARA FM NARROW (1200) gateways and P2P stations. However, you'll probably have problems using SoundModem to connect to 1200bps packet gateways and P2P stations.?
Unless you can find some reasonable compromise settings when leaving the radio in the 9600bps configuration, you'll probably need to change a couple of settings on the radio, and the JU4 position in the DRA-36, to switch back and forth between 1200bps packet and VARA FM modes. I've been experimenting with options in the SoundModem config file, which may help with this problem. I'll post another reply if I come up with anything.
