The FM broadcast band, used for FMbroadcast radio by radio stations, differs between different parts of the world. In Europe, Australia and Africa (ITU region 1), it spans from 87.5 to 108.0 megahertz (MHz) - also known as VHF Band II - while in the Americas (ITU region 2) it ranges from 87.9 to 107.9MHz, though only two low power stations are licensed for 87.9MHz; normal full power stations start at 88.1. The FM broadcast band in Japan uses 76.0 to 90MHz. The OIRT band in Eastern Europe is from 65.8 to 74.0MHz, although these countries now primarily use the 87.5 to 108MHz band, as in the case of Russia. Some other countries have already discontinued the OIRT band and have changed to the 87.5 to 108MHz band.
Frequency-modulated radio waves can be generated at any frequency. All the bands mentioned in this article are in the very high frequency (VHF) range, which extends from 30 to 300MHz.
Tuning in stations on the FM broadcast band. Software is SDRuno, receiver is RSDP2 by SDRPlay. Location is near Baltimore. Antenna is J pole up 30 ft, tuned for 2m. Video was captured and uploaded using X-Split Broadcaster.

Ceecom Antennas FM broadcast band dipole (88 - 108MHz)
A look at Ceecom Antenna's dipole for the FM broadcast band (VHF Band II) including reception of a couple of semi-local but low power stations from Brighton.
First impressions are very good. The antenna is rugged, tuneable and can handle 1kW continuously if you are licensed for such things!
Please note that I have no connection with Ceecom Antennas other than as a satisfied customer.

Arizona Signal Watcher Ep014 - 5-element Yagi for the FM broadcast band
The build and demonstration of a compact 5-element Yagi for the FM broadcast band designed by K6STI. This antenna works at least as well as the classic Antennacraft FM6 antenna, and can be built in an evening. This antenna is particularly useful for sporadic-E openings near the summer solstice, but also for tropospheric enhancements, and even general FM radio listening.
