Michael, can you help me understand what the problems are, and what,
if anything, we can do on the GNU Radio side to resolve them? It
sounds like some of these problems may have

Hi Guys
I’m new to the list and have a query regarding USB VID PID’s.
The HPSDR community are currently prototyping a single board HF
transceiver. The product is named Hermes.
A list of SDR USB PID’s seem to be maintained

This is incorrect. The block is derived

And how does the FPGA scaling with set_tx_scale_iq() work?
Don't use it. It's a bug that we expose it.
(It's a final scaling that the library may someday use.)

Hi Eric,
I have a few questions regarding MIMO + GNU RADIO.
1. How can i use MIMO with GRC?
If i use one USRP sink, it considers one whole USRP board. I cannot use two
daughter boards of the same USRP board using USRP sink.

The example below writes 32 bits in a single transfer.
You can confirm this by looking at the SEN and CLK signals.
To send 24-bits, give it 3 bytes.
