I would second Andy's comments. ALE400 in ARQ mode is something that has to be experienced; quasi full duplex is really nice. A few weeks ago, I had a QSO with Txema who is located in Spain. Even though the conditions were very poor and we were both running about 25 watts or so, we were able to have a very nice QSO on 20 meters. When deep QSB occured, the ARQ kicked in and automatically did the retries. I would nominate this mode ( and Patrick's implementation!) as one of the major milestones for digital radio for 2007. 73, Bernie > > I think many people have had time to experiment with ALE 400 in ARQ > mode and the feedback about the throughput has been very good.
