RSGB Band Plan January 2020

2M RSGB Band Plan (effective from 1st January 2019) The following band plan is largely based on that agreed at IARU Region 1 General Conferences with some local differences on on frequencies above 430 MHz. 144MHz (2m) Necessary UK Usage Bandwidth 144.000-144.025MHz 2700Hz All modes - including Satellite downlinks 144.025-144.100 MHz 500Hz Telegraphy (including EME CW) 144.050 MHz Telegraphy Centre of Activity 144.100 MHz Random MS telegraphy calling (Note 1) 144.100-144.150 500Hz Telegraphy and MGM EME MGM activity (Note 7) 144.150-144.400 2700Hz Telegraphy, MGM and SSB 144.200 MHz Random MS SSB 144.250 MHz GB2RS news broadcast and slow Morse 144.260 MHz See Note 10 144.300 MHz SSB Centre of Activity 144.370 MHz MGM MS calling 144.400-144.490 Propagation Beacons only 144.490-144.500 Beacon guard band 144.491-144.493 MHz Personal Weak Signal MGM Beacons (BW: 500 Hz max) 144.500-144.794 20 kHz All Modes (Note-8) 144.500 MHz Image Modes (SSTV, Fax etc) 144.600 MHz Data Centre of Activity (MGM, RTTY etc) 144.6125 MHz UK Digital Voice (DV) calling (Note 9) 144.625-144.675 MHz See Note 10 144.750 MHz ATV Talk-back 144.775-144.794 MHz See Note 10 144.794-144.990 12 kHz MGM / Digital Communications 144.800-144.9875 MHz Digital modes (including unattended) 144.8000 MHz Unconnected nets - APRS, UiView etc (Note 14) 144.8125 MHz DV Internet voice gateway (IARU common channel) 144.8250 MHz DV Internet voice gateway (IARU common channel) 144.8375 MHz DV Internet voice gateway (IARU common channel) 144.8500 MHz DV Internet voice gateway (IARU common channel) 144.8625 MHz DV Internet voice gateway (IARU common channel) 144.9250 MHz Digital usage 144.9375 MHz Digital usage 144.9500 MHz Digital usage 144.9625 MHz FM Internet voice gateway 144.9750, 144.9875 MHz tbd (Note 11) 144.990-145.1935 12 kHz FM/DV RV48 - RV63 Repeater input exclusive (Note 2) (Note 5) 145.200 12 kHz FM/DV Space communications (e.g. I.S.S.) - Earth-to-Space 145.2000 MHz (Note 4) & (Note 10) 145.200-145.5935 12 kHz FM/DV V16-V47 FM/DV simplex (Note 3) (Note 5) (Note-6) 145.2250 MHz See Note 10 145.2375 MHz FM Internet voice gateway (IARU common channel) 145.2500 MHz Used for slow Morse transmissions 145.2875 MHz FM Internet voice gateway (IARU common channel) 145.3375 MHz FM Internet voice gateway (IARU common channel) 145.5000 MHz FM calling (Note 12) 145.5250 MHz Used for GB2RS news broadcast. 145.5500 MHz Used for rally/exhibition talk-in 145.5750, 145.5875 MHz (Note 11) 145.5935-145.7935 12 kHz FM/DV RV48 - RV63 Repeater output (Note 2) 145.800 12 kHz FM/DV Space communications (e.g. I.S.S.) - Space-Earth 145.806-146.000 12 kHz All Modes - Satellite exclusive Note 1: Meteor scatter operation can take place up to 26kHz higher than the reference frequency. Note 2: 12.5kHz channels numbered RV48-RV63. RV48 input = 145.000 MHz, output=145.600 MHz. Note 3: 12.5kHz simplex channels numbered V16-V47. V16=145.200 MHz. Note 4: Emergency Communications Groups utilising this frequency should take steps to avoid interference to ISS operations in non-emergency situations. Note 5: Embedded data traffic is allowed with digital voice (DV) Note 6: Simplex use only - no DV gateways Note 7: EME activity using MGM is commonly practised between 144.110-144.160 MHz Note 8: Amplitude Modulation (AM) is acceptable within the All Modes segment. AM usage is typically found on 144.550MHz. Users should consider adjacent channel activity when selecting operating frequencies Note 9: In other countries IARU Region-1 recommend 145.375 MHz Note 10: May be used for Emergency Communications and Community Events Note 11: May be used for repeaters in other IARU Region-1 countries Note 12: DV users are asked not to use this channel, and use 144.6125 MHz for calling. Note 13: not used Note 14: 144.800 use should be NBFM to avoid interference to 144.8125 DV Gateways LICENCE NOTES : Amateur Service and Amateur Satellite Service - Primary User. Beacons may be established for DF competitions except within 50 km of TA 012869 (Scarborough) Page 20
