I glad you found the info interesting. I saw you post on the flex
relector and Tim's response. I think he missed that I am using the
EMU1212M on the RXTX version of the softrock. The EMU1212M is using
the very high quality AK5394A A/D that I'm sure he is familiar
with :)) I don't think this could be called a "cheap card" by any
means.. Price is around $150 to get one of the best A/D converters
on the market.
He mentioned that it is only 2 channels. That is correct and I am
using it for the I/Q TX and RX processing. For the base band audio
(i.e. the other 2 channels) you can use any junk audio card you
have. I am using the built in Realtek HD audio of my motherboard.
I am using the supplied ASIO driver from EMU that works great on all
the data rates.
I have done some additional receiver performance testing and will
try and post the results tonight. Quick summary:
Excellent performance of 82db 3rd order dynamic range with close
spacing (2Khz). Not many receivers can beat this (including the
Icom 7800)!! Wide spaced DR is 91dB @20khz spacing.
This softrock RXTX is one excellent product when hooked up to a
