VHF low band 43 MHz VHF "43 MHz CB" allocation allowed in Italy only. 24 channels. Similar to CB, JAKT Radio 31MHz in Sweden and other VHF/UHF services such as FRS, GMRS, MURS, Freenet, etc.

5 watts maximum power limit, no limits on antenna height or gain. FM mode only. Each channel has a "recommended use" - 12.5 kHz steps 43.3000 MHz to 43.5875 MHz. 43.3-43.6 MHz band.

Many radios sold for this band can be easily modified for "export" use - which expands frequency coverage to 42.3000 MHz to 45.0875 MHz and increases transmit power from 5w to 20w or 25w. Apparently their use is quite popular in Ukraine and elsewhere. Examples of these radios include the Dragon MX-430, Dragon SY-5430, Intek K-43, Intek SY-343, Intek SY-90, Intek SY-5430, Intek SY-5430M, Alan HM-43, Alan HP-43, Alan HP-43 PLUS and others.

According to locals, the 43 MHz band is still used (as of late 2019) for voice communications as well as data/telemetry systems. This is analogous to the data burst, data link, paging or telemetry systems found on the license-free 26 MHz and 27 MHz RC frequencies and MURS frequencies in the United States.
