8.8.3 IARU Region 1 Technical Recommendation D.1.2 NOORDWIJKERHOUT 1987 1. Modulation methods IARU Region 1 page 120/148 Version 5.40 VHF managers handbook STANDARDS FOR DIGITAL COMMUNICATIONS - FM/AFSK (where allowed in the bandplans) - FSK : at speeds below 300 bit/s FSK is preferred - PSK : at speeds above 300 bit/s PSK is preferred General Applications : Shifts for FSK and FM/AFSK : at 1200 bits per second -1 kHz below 1200 bits per second -850 Hz, 170 Hz (preferred) Mark is always the higher frequency. Note. For FM/AFSK the audio frequencies are : - space 1275 Hz - mark 1445 Hz or 2125 Hz, depending on shift Packet-Radio Applications: 1 ) 2. Coding/bit- rates 2 ) 3. Protocols for 300 bit/s transmissions using FSK a shift of 200 Hz should be used; for 1200 bit/s transmissions using FM/AFSK audio frequencies of 1200 and 2200 Hz should be used (as in the Bell 202 standard). On the bands below 30 MHz the signalling speed shall not be more than 300 bit/s. - Baudot : 45.45, 50, 100 bits per second (50 bit/s preferred) - ASCII : 1 start bit, 7 data bits, 1 parity bit, 1 stop bit. Parity: if generated - even parity if not generated - parity bit set to space 110 bits per second preferred. - Packet Radio : AX-25 as published by ARRL - AMTOR : CCIR 476-1, modes A and/or B. 2 Packet-Radio : It is recognised that in the future higher data rates will be achievable through the use of different modulation methods. It is recommended, however, that in all cases for the frequencies used for communication between the user and a network access point the bandwidth should not exceed 12 kHz. For links between packet-radio nodes higher data rates and larger bandwidths may be used. For such high speed links ( greater than 1200 bit/s ) FM/AFSK is not preferred
8.8.4 IARU Region 1 Technical Recommendation D.2 (deleted DAVOS 2005) CEFALU 1984 8.8.5 IARU Region 1 Technical Recommendation FM.1 BRUSSELS 1969, SCHEVENINGEN 1972 A. TECHNICAL STANDARD FOR NARROW BAND FM For FM within Region 1 a Maximum Modulation Index of 1 and an audio band restricted to 3 kHz shall be used B. TECHNICAL STANDARDS FOR FIXED CHANNEL FM STATIONS 1. Traffic mode Simplex on one channel. 2. Maximum Deviation ∀ 3 kHz, 12K0F3E. 3. AF response 300 - 3000 Hz, outside this band down with 12 dB/octave. 4. Pre-emphasis +6 dB/octave in the transmitter. 5. De-emphasis -6 dB/octave in the receiver.
