Listening below 136.5 and 'odd' hours gave unexpected results! Stations heard 25/4 (morning only): Slow CW: G3YXM (O) Normal CW: PA0LQ (579); G3YXM (579); DF2PY (549); ON7YD (539); G3KEV (549); G4GVC (569); DJ6FU (539) I posted this report because i heard some stations this weekend (caling CQ only a few times) who where not mentioned in the other reports. By the way long CQ's may be anoying to some, it gave me a fine opportunity to improve my e-field probe changing the set up it at least three times (including measurements). This proved to me once again that observing 'weak' but more or less stable live radio signals is a superior way of experimenting and testing receiver / antenna performance compared to tests with signal generators. I have decided to keep the modification with the best signal - noise ratio. Tests i did before with the signal generator and observing strong commercial LF stations indicated however that a version with more gain followed by a low-pass filter and attenuator should have worked better, but it did not! Is there some room on the narrow 136kHz band for a limited (low-ERP) beacon experiment and are there amateurs interested in operating/monitoring such transmitters ?
