I don't think we need "experimental" stations to prove in the use of
500Kc/s for radio communications.
That's not the purpose of the experimental license, Anymouse.
The purpose of the license is to prove that less-than-optimal
loaded antenna systems can provided the desired communications.
Previous users of the band were not so restricted and had antenna
farms that were hundreds of feet high and covered acres, not a few
hunded square feet. Some of the antenna combinations being tried at
600 meters might be likened to trying to use a rubber duck on 20
meters.

Most maritime mobile stations (the "previous users") aren't "hundreds of feet high and covered acres"! Except for a few passenger vessels, most "antenna farms" at sea are located on the stack or aft deckhouse and are intermingled with cargo cranes, mast stays, and other deck machinery and paraphenalia. The most common 600-meter-band antennae at sea are 28-foot base loaded whips, side mounted with huge masses of steel, aluminun, and other conductive surfaces in the near-field. Only large non-cargo vessels (ie., the Titanic and QE2) have the luxury of stringing longer wire antennae.
This WD2XSH "experimental station" boon-doggle is remindful of amateur wheel-wrights slicing cross sections from logs of petrified wood out here in the desert, boring a hole somewhere near the center, and crying "Eureka, we've communicated on 600 meters... someone quick go tell the BF Goodrich!"
