I just noticed the prevailing observation is that more RAKs around than RALs. Which had seemed to me the opposite. Unless there's more "churn" to RAKs - fewer people hoarding them and more being exchanged on market. I don't think the Navy in WW2 made more use of LF-VLF than HF. That's the conclusion i get from the WW2 accounts i've read. -Hue Miller
