HF Packet is also sensitive about the baud rate, 300 baud Packet won't decode if you are set up for 1200 or 9600 baud. Note that no difficulty was experienced in decoding from the recording at the proper aud rate, despite some obvious signal fading.

That typifies HF Packet in the past, where tuning was a matter of luck as much as anything else. These days we use a waterfal display to get on the same frequency, and the difference is like night and day. - Am working on 'snap tuning' to make this process automatic. Most of the disparaging talk about HF Packet is motivated by politics, and does not come from actual knowledge. If you talk to the PC types who disparage Packet, it turns out that very few of them have any recent experience with the mode, they're still stuck in the 1980's.
