Perhaps with a little FEC and the slower speed and a shorter frame, Packet might have worked better on HF. I remember reading that packet requires a rather high S/N ratio to work. The only redeeming value is that it is an ARQ mode and it can run on a sound card such as with Patrick's Multipsk p

188-141 does not merit adaptive equalization in my opinion. At 125 tones per second, one of 8 tones is turned on. Each tone sends 3 bits as a result. The data is encoded with a Golay code. This is about twice as fast as is optimal for most HF channels given this kind of transmission (IM

> This is needed, >absolutely mandatory, to mitigate the fading multipath HF channel. Bob, Thanks. I have not had a opportunity to send images with 188-110, but after reading the specification, I thought adaptive equalization would be necessary. I look forward to sending images. I have be
