commit ea4702e33b5828edcb5c6b515cc4ef6b1e88a17e Author: dave-w1hkj 
<w1hkj at bellsouth.net> Date: Fri Apr 16 18:22:27 2021 -0500 Add OFDM 
modes for NBEMS * OFDM-500F for HF SSB - survives HF NVIS/long path - 
4-carriers of 62.5-baud 4PSK = 250 bps - 1/2 rate K=15 FEC with 4sec 
interleaver * OFDM-750F for HF SSB - survives HF NVIS/long path - 
3-carriers of 125-baud 8PSK = 562 bps - 1/2 rate K=13 FEC with 3.2sec 
interleaver * OFDM-2000F for HF-SSB/FM - 8 carriers of 125-baud 8PSK = 
2000bps - 2/3 rate K=13 FEC with 3.2sec interleaver * OFDM-2000 for 
HF-SSB/FM - 4 carriers of 250-baud 8PSK = 3000bps - NO FEC, meant for 
line-of-sight * OFDM-3500 for FM 9600-port - 7 carriers of 250-baud 8PSK 
= 5250bps - NO FEC, meant for line-of-sight - Requires Signalink 
made-after 2018 connected to the 9600-jack * OFDM-2000F CPU-load fix - 
FEC of previous mode too heavy for some CPUs . Reduced to: K=11 FEC with 
1600msec interleaver . Other mode parameters unchanged * Added 
Vestigial-carrier based AFC to OFDM modes - Increases robustness and 
tolerance to drift * OFDM 2000F hold - commented out OFDM 2000 and 2000F 
modes for bugfixes - OFDM 500F, 750F, and 3500 are complete commit
