There has been a discussion regarding the Excalibur's ability to accurately measure a station's excact frequency, down to the hertz. Well it can, provided it is correctly calibrated, but not on every DDC spectrum! In fact, for nine of the 21 available DDC spectra the minimum resolution bandwidth of the Demodulation panel is 2 Hz, not 1 Hz. The best demodulation resolution is available for these DDC spectra: 20, 24, 32, 64, 125, 160, 320, 640, 800, 1250 and 1500 kHz.
When you record a DDC spectrum, it doesn't matter which RBW the Demodulation panel is set at. If it is set at, say 160 Hz during recording, you will still be able to see 1 Hz during playback.
A totally different subject: On July 23 we are experiencing a weather with a ferocity that is rare even during the stormy autumn months: Severe gale winds, heavy rainfalls and temperatures around 3 Celsius. A few days ago we enjoyed 23 Celsius...
Yes. And the first snow for this "winter" was observed near the ENOX pedition QTH this morning (Enontekiö). Sounds like we are approaching the next mw season! In southern Finland +25 still...
