	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: not used
	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: Ad-hoc Low power repeaters,  5W erp max
	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.
	Note specific conditions apply within 50 km of TA 012869 (Scarborough)
	Notes to the Band Plan
	ITU-R Recommendation SM.328 (extract)
	Necessary bandwidth: For a given class of emission, the width of the frequency band which is just sufficient to
	ensure the transmission of information at the rate and with the quality required under specified conditions.
	The use of Amplitude Modulation (AM) is acceptable in the all modes segments but users are asked to consider
	adjacent channel activity when selecting operating frequencies.
	Foundation and Intermediate Licence holders are advised to check their licences for the permitted power limits and
	conditions applicable to their class of licence.
