I am pleased that ARQ FAE, a modest speed 8 bit ASCII data ARQ sound card mode, is available for the first time on MS OS. This is a major breakthough.
The speed is slower than P2 and we must not forget that the bandwidth is extremely wide at 4 times P2. But it is moving us in the right direction for higher speed ARQ sound card modes that work much deeper into the noise than the previous attempt with SCAMP. ARQ FAE is in the 150 + wpm speed, Pactor 2 can got up to maybe 500 wpm, maybe more with compression? SCAMP was close to 1000 wpm and had a slightly wider footprint than ARQ FAE, but that was under really good conditions. In comparison, P3 has a similar footprint but can operate with a raw speed of over 2000 wpm and with compression can get way over 3000 wpm in the best conditions. So we have a long way to go, but we are making progress. 73, Rick, KV9U John Bradley wrote: >Have a look at Patrick's 141A ARQ FAE mode on Multipsk.
