Calling frequencies across Europe
The FM calling channels are 145.500 MHz on 2m, 433.500 MHz on 70cm and 51.510 MHz on 6m. For SSB and CW, the centres of activity are 144.300 and 432.200 MHz, with CW around 144.050 and 432.050 MHz, and 50.150 MHz on 6m. APRS is on 144.800 MHz throughout Europe. Make your call, then move off the calling channel once you've made contact.
Differences between countries
The 2m plan is almost identical across Europe. 70cm differs more, because countries use different repeater shifts and have different national segments between 430 and 432 MHz and between 438 and 440 MHz. 6m allocations vary most of all. Check your national society's version before using repeaters abroad.
How the VHF and UHF bands are organised
The VHF and UHF bands follow the same pattern almost everywhere: CW and weak-signal SSB at the bottom, with calling frequencies for long-distance contacts, then beacons, then FM simplex, repeaters, digital voice and data, with satellites in their own protected segments. Keep weak-signal segments clear of FM, and keep FM off the beacon and satellite segments.
For working out repeater channels and offsets, see the CTCSS tone list, and for FT8 and other data frequencies the digital mode frequencies page. The satellite pass predictor shows when to listen on the satellite segments.
