Dear LF group,
I don't think it is possible for any one piece of software to be all
things to all people - for the person who is trying to copy a QRSS
signal, Argo is very well "tuned", but the trade-off for this
specialisation and being simple to use is that it is less versatile. If
you want to examine the spectrum of a different type of signal, it is
better to use a program like Spectrum Lab or Spectran, where you
have greater control over the parameters of the FFT and display.
Having said that, I still think a signal level/SNR measurement
function would be a valuable addition to Argo, even if you are only
using it for QRSS. It is important to be able to get a meaningful
measurement of signal strength - eg. 3dB down on yesterday,
10dB above the noise level, rather than just calling it T,M or O.
Cheers, Jim Moritz
