Hi Phil,
I must second what Jim has to say about a general coverage rig and SDR.
I too use the RSP-1, and once it is in a metal case it is a really nice
rig.
The versatility is amazing. I am now using them for RFI detection, and
SWLing.
I also characterize my entire RFI background using the RSP-1 to create a
spectrogram of entire bands at a time. it spots every single RFI source
in the area at once, and displays the relationships they have to each
other.
See:
http://nk7z.net/sdr-rfi-survey-p1/
for an example of this.
My next project is to get the RSP-1 going on a Raspberry Pi.
73s and thanks,
Dave

HI Phil,
I suggest that you take a look at various SDR RX options and the
half-dozen or so software programs written to control them. I have an
SDR-Play RSP 1, about $130 from HRO, and a FunCube Dongle ProPlus, about
$175 from the UK. These are both VERY versatile products, and have
surprisingly good performance. There's a brief outline of their
performance for chasing RFI in k9yc.com/KillingRXNoiseVisalia.pdf that
is focused on their usefulness as spectrum displays to identify types of
RFI, and to chase RFI. But they are good for FAR more than that. Here's
a better summary of what's available.

ND0B, who has a serious VHF/UHF station and is one grid away from
completing the FFMA award for working all 6M grids in the continental US
(see his qrz.com page), says that he would not have worked our
expedition to the very rare CM79 grid without an RTL dongle and Simon
Brown's SDR Console software! He says it outperforms his Flex 6700 for
sensitivity and noise. Simon, G4ELI, is a fine programmer, and was the
author of the original Ham Radio Deluxe software, and a digital mode
TX/RX program to go with it. He sold that software several years ago
because support was pulling too much time away from programming.

I've been busy with other projects, so haven't gone beyond loading
software and verifying that everything works. I'd be willing to bet that
there's free software to do damn near anything with these radios!
There's software to trace aircraft beacons, decode broadcast TV in
various formats, SWL, and ham operation. To use them as a SWL RX,
simply plug the SDR into a USB port and listen on computer speaker,
headphones, or a stereo rig connected to an audio output of the computer.
