great audio programs
RecAll Pro

You
should note that neither Total Recorder nor any of the other
virtual recorders about which we know does continuous time-stamping
like several of the MD recorders do. There are running indications
(in minutes and seconds) of how far you are into the recording,
as well as its total play-back length.
If you allow Total Recorder to save the recording automatically,
the default title is the time and date of the end of the recording.
The lack of absolute date-stamping does not seem to be much of a
problem in practice.
RecAll
Pro
is doing that for you. It's a tiny little recorder that continuously
time and date stamps recordings.
Furthermore it has a Vox (voice-activation). That means that you
don't have to strangle with setting the times of the receiver and
once again that of the recorder. RecAll records only when there
is audio available at the line-in and stops when there is no audio.
You can activate settings to start a new file every time when there
is audio available again and file names can have a date prefix if
you want.
There's also the non-Pro version but I recommend the Pro. Both can
be tested during 15 real use days (not calendar days).
RxWings

Ergo is a real nice program, but I advise you also to take
a look at RxWings.
It's Freeware and works with the AR7030 from AOR, the NRD-535(D)
from JRC and the RX320 from Ten Tec!
Ergo looks nicer but RxWings doesn't need correct frequency tuning
for displaying.
What's also nice is that you can tune the receiver while the PC
tracks what station you are tuned to (The 'snapping' range can be
modified). And let's hope that there will be a new MW-ILG in the
near future as mentioned on Bernd Friedewalds's site.
There is also a possibility to do a spectrum scan. This is probably
worthless compared to the DX-Radar but the nice thing about RxWings
is that the source code is open. So if you have programming skills
it might be possible to 'convert' the spectrum scanner into a DX-Radar.
CoolEdit 2000 and SR5
John Wilke, WB9UAI

If I may suggest two other software titles worthwile to look into:
CoolEdit2000 for audio recording, and SR5 for audio DSP.
CoolEdit has a graphical image of the audio file that allows
easy editing of a whole night's recording. It also has excellent
filtering, and stretching capabilities.
SR5 is indispensible for LW beacon dxing with amazingly sharp
filter skirts and notch filters making it possible to separate two
CW signals that are only a few 10hz apart.
