There are a number of documents that describe the U.S. Army in Vietnam using the hand-crank-generator-powered, all vacuum tube, Morse only, 10-watt AN/GRC-109 HF station with a buried antenna. Here's a description of a long-wire antenna in bambo tubes, 18 inches below ground:

If it worked using a low power transmitter in such a critical application, I suspect that it would be worth a try for ham hobby purposes.
