[hpsdr] Questions re: FPGA firmware

[Simon G4ELI/HB9DRV]

Alex,

Your work is outstanding. It would be nice were I able to display a very
wide display, for example 2MHz or more in one go.

Aren't users annoying ?

7-band firmware for Hermes is already available. I could not test it myself,
but I was told that it works fine with cuSDR at the PC side. As I
understand, this firmware will be optional, because its use leads to a
higher current from the power supply and more heat dissipation in Hermes,
more traffic through the network adapter, and requires more CPU power in the
PC than a 2-band version.

The capacity of the FPGA in Hermes is much higher than needed for 7
receivers, but most of it is used by non-radio code, such as network
protocols. I created the 7-band code by keeping that part intact and
squeezing the receivers in the available space. Now I am re-writing the
whole networking module, hoping to save space for a few more receivers, but
this is a huge piece of work that will keep me busy for the next few months.
