I use it sometimes for measuring the relative levels of signals. Alberto, Wolf and others have done a great job in providing us with FFT S/W and I would just like to make a comment. One of the main virtues of Argo (as well as its effectiveness) is its simplicity. This is of utmost importance in an operational situation. Ensuring that the receiver is set up correctly, that the transmitter operating correctly, while at the same time (under certain conditions) operating an HF link can take a lot of effort. To have software that is so easy to use is a big help in these situations. However, there is always improvements that can be made. Might I suggest that Alberto does development work, such as amplitude measurement, on Spectran, which already has this uncalibrated facility. Having said that I find that the improvements so far made to Argo have not compromised simplicity. Regards, Peter, G3LDO e-mail Web
