Have you seen VARA FM Wide pass data through a Digirig Mobile at wide speeds? I mean speeds greater than 14,000 bits/second, which are only supported by the wide modes of VARA FM. The VARA display might look like this. VARA FM speeds are listed here.
If you’ve seen this, please tell us about the radio, antenna, computer and software versions you used.
I’m not sure a Digirig Mobile has enough audio bandwidth to do this. Demonstration of such a high data rate would be evidence that it does. I’m not equipped to test it.
If radio can handle the wider bandwidth, Digirig will not be a bottleneck.
The standard voice band in ham is 2.4K while Digirig’s bandwidth is 24K (48K sampling rate) so there is quite a bit of margin.
