Frank D: One example was Crosley's transmitter in Bethany, Ohio. The only Ohio station listed in my booklet is W8XAL in Cincinatti, on daily from 5-6 am PST on 6.06 MHz, and from 6-9 pm, same freq. Interestingly, during the 7-9 pm slot, W3XAU in Philly was also on the same freq. Note that these are *amateur* callsigns, not standard (commercial) four letter signs. These stations were likely legally considered on the same level as hams with fleawatt tx's because there was no provisions in federal law to license commercial stations on SW-the "domestic broadcasting" ban that's been talked about so much in this group. W6XKG was on 24/7 on 25.95 MHz. From what I can tell, no station in the world shifted frequencies. I guess they were one transmitter, one antenna (and one crystal G) stations back then. Over the years I've seen articles on old SW transmitters, as well as looked at some tube era ham level SW tx's. It seems that ALL SW tx's were crystal controlled until the 1960s, when transistorization made tunable transmitters possible. A lot of these Third World stations that stay on the same freq for decades, and whose transmitters can be tracked from owner to owner by freq usage, are one crystal setups. I suspect that the crystals in these tx's were (and are) sort of hardwired in like the early tube computers had one "program" that could only be changed by rewiring. |
