[hpsdr] Hermes and protocol 2

[Kjell Karlsen]

Hi Bob.

Thanks for the information.

I have been in contact with Phil, VK6PH and he inform that there may be  
samples of Hermes having  a FPGA that is not able to handle the 1GB speed  
of Protocol 2. So it seems as I have 2 of them, HI. As both of the boards  
are from the prototypes that were made by myself and TAPR, the FPGA can be  
 from the same batch in production. Some of my friends also have similar  
boards so I must have them to test if they works on Protocol 2.

It is a bit strange that the boards works perfect in RX mode on all  
sampling frequencies but they are completely dead in TX mode.

73, Kjell
