Hi Steve,
I would go with the AM-3924 also know as the Harris RF-110A. It will do
legal limit RTTY all day and all night for years. Has automatic band
switching and tuning capability too. You can pick them up surplus and it
doesn't take much to mod them. Replacement tubes if you ever need them
aren't too expensive, the "service manual" is so complete that anyone who can
read can likely service it.
