http://wsprdaemon.org/fst4w.html WebThe 5-minute frequency drift was ~1.5Hz (~0.148ppm), which explains why the transmitted signal of FST4W-300 by this transmitter on the 30m band was not able to decode. First 2-minute frequency drift was ~1.2Hz (in the 2nd transmission case), which explains why WSPR on the 30m band works OK on this transmitter. outbound bellen tipsWebfrequency the bandwidth-time product (BT) is 1, that is, a 2 s long pulse will have a bandwidth of 0.5 Hz.

WebJanuary 22, 2024 Leave a comment. As has been mentioned before, the transmit frequency stability of the QRP Labs QDX transceiver isn’t quite good enough for some of the narrow-band modes. It works fine for WSPR and FT8, but slower modes such as FST4W-300, -900, and -1800 require stability that the QDX’s internal TCXO just can’t provide. http://wsprdaemon.org/
