PSK63F PSK63F was designed to provide better performance than PSK31 in two areas - first, the higher baud rate (62.5 baud) significantly reduces the effect of polar Doppler instability, and secondly, errors are reduced through the use of full-time FEC. Unlike QPSK31, Doppler sensitivity is not increased when FEC is used. Through more efficient coding, it is also slightly faster than PSK31, although the signal bandwidth is doubled. Use PSK63F for short-haul HF DX, say up to 10,000 km, for local QSOs and for VHF. The mode is very tolerant of drift and inaccurate tuning. It is a good mode for digi-beginners, and an excellent mode for QRP operation. Good for DX on 6m, or 15m - 10m when the band is open. PSK63F is useful for (small) text file transfers under reasonable conditions. It is not as sensitive as PSK31 or as QRM tolerant as MFSK16.
