Hello,
was curious if anyone has a way to use the IQ data available over
USB-3 from the rear of an IC-7610 to feed into MAP65?
I have the HDSDR software working with the ICOM supplied driver but
as yet have not managed to get MAP65 to work with this source.
With the new Q65 mode being spread across many regional frequencies
on 50 MHz, it is getting harder to keep an eye on each of the
frequencies but with the Q65 mode in MAP65 it might help me and
others with this, plus be handy for 50 MHz EME when the moon has
multiple Q65 QSO's in progress.

Hi Peter,
MAP65 requires either a single or dual I/Q feed via an audio device at
96,000 frames per second, or a Linrad compatible UDP feed of one or
two I/Q data channels, also at 96,000 frames per second.
Icom provide some tools that can consume the IC-7610 single channel
wide-band I/Q feed on the [USB 2] connector as an ExtIO library (MS
Windows only) that can feed various SDR console applications. If one
of those SDR console applications can decimate and output that at
96,000 frames per second to an audio device, then that would be
compatible MAP65 in single polarization mode.

Hi Peter,
note also that MAP65 only supports the 60 second T/R period variants of
Q65 and that is unlikely to change, most terrestrial Q65 operation uses
30 second periods.
