30 TO 50 MHz today is a wasteland. When I started my LMR business in 1966, I rented 30-50 MHz radios and they worked great. A few years later, skip came and Florida & Texas stations blew off the air mobiles just 10 miles from their Los Angeles base. That was the end of my Low Band VHF rental business.
I also installed a 250 watt base station in Upland, California on 35.7 MHz. for a tow service. When the local hospital found we had a few voice pagers working on the system, they asked for a demo inside the hospital to show the doctors. Keep in mind the hospital was only 1 mile from the transmitter. In the old building it worked great, but in the new high-rise building, it did not work at all. I could see the transmit antenna from the hospital window. It turned out the new building was all concrete and no window was larger than 5 ft square. Therefore, the largest aperture or opening was smaller than 1/4 wavelength at 35.7 MHz, so the building effectively shielded the signal. The pagers would work 70 miles away, but not 1 mile away.
Low band VHF would work great to send data to billboards or schedules to bus pickup points or traffic sign updates or whatever. So many applications for old paging channels. Also the mid-band VHF between 72-76 MHz can be licensed for point to point applications in business or common carrier voice or data using 25 KHz wide-band channels. So much life still left in this spectrum for the creative small business person. Share some ideas for others to use.
