[ARC5] Regeneration

[Leslie Smith]

Hello Ken,

Below you wrote that the German and US TRF receivers didn't suffer from "touchy" operation/regeneration.  Do you mean that these sets were "nice" to use, despite requiring double-handed operation?  Or (in contrast) do you mean that the design was sufficiently good that these sets didn't require adjustment across the band?  (I suspect the former, but will look at the design very closely if the latter!)

Les
