Re: [IRCA] Laptop Computer Requirements for an SDR

[Guy Atkins <dx@xxxxxxxxxxxxx>]

Hi Patrick,

Barry mentioned problems recording to an external hard drive with Perseus.
You can indeed sometimes have issues with a USB 2.0 connection, depending on
the computer and certain Windows settings. The connection type  "eSATA" is
the way to go for the speediest transfer of the big chunks of data that are
saved (which represent more than the entire MW band when you record at the
largest frequency width that Perseus can handle). A few laptops have eSATA
ports (I think), but most of us use what is called an eSATA Express Card
adapter. These are inexpensive cards that plug into the Express Card slot on
modern laptops. Then an eSATA cable goes between the adapter and the
appropriate hard drive that can take eSATA cables.

I like HDs like the 1 TB model GD1000EU from Fantom, which Buy.com has right
now for $74.99 after $20 rebate, with free shipping.

You can always record to the internal hard drive of the laptop, which
normally works without a hitch. However, space on most laptop HDs is limited
and you'll want another HD if you want to archive any of the Perseus
recordings (specially formatted WAV files that the receiver generates).

There are some other tweaks you can do to Windows settings to help ensure
that the Perseus recordings proceed without audio "hiccups", and they are
documented on the Perseus SDR Yahoogroup as well as in a few places on my
blog.
