For-profit stations depend on advertising revenue to finance their operation, other than in-house promotions such as sponsored concerts or special live remote broadcasts. I’ve completed this project on a protoboard and it doesn’t seem to work. "padding-right": "20px", For both transistors, the 2N3707 was used which is equivalent to the BF494. Built this and does not work, the LM368 amp works fine, but the tuning coil with capacitor do not pick up RF. The Japanese VHF FM band is only 14 MHz wide and this limits the number of stations that can be accommodated, and as a result, many stations use AM. } "font-weight": "bold" } Stations like Kiss FM often promote big advertising agencies from which they pull in large amounts of cash. Frequency modulation is widely used for FM radio broadcasting. There is only a humming sound whats the problem??
