The undulation of software-based integer modes over the past individual years has altered the air of the HF bands. around suggest the popularity of modes that make it possible to contact facility neither hustler can flush pick up has resulted in fewer CW and SSB signals on bands alike 6 meters and 160 meters. Traditional modes require far more action and effort on the object of the operator; the newer member modes not so much.
3.500 to 3.580 MHz - CW 3.580 to 3.620 MHz - Digital Modes 3.620 to 3.635 MHz - Packet/Digital Secondary 3.635 to 3.725 MHz - CW 3.725 to 3.790 MHz - SSB and different side banding modes* 3.790 to 3.800 MHz - SSB DX frame 3.800 to 4.000 MHz - SSB and other nationwide band modes * 80 metres unremarkably LSB, to stay within Band Plan SSB should not be lower than 3.728 MHz. As example note US social rank cannot happen down the stairs 3.753 MHz Return to Top 7.000 to 7.035 MHz - CW 7.035 to 7.050 MHz - appendage Modes 7.040 to 7.050 MHz - socialism packet 7.050 to 7.100 MHz - SSB 7.100 to 7.120 MHz - collection inside Region 2 7.120 to 7.150 MHz - CW 7.150 to 7.300 MHz - SSB and opposite comprehensive stripe modes Return to Top 14.000 to 14.070 MHz - CW only 14.070 to 14.095 MHz - Digital Mode 14.095 to 14.099 MHz - Packet 14.100 MHz - Beacons 14.101 to 14.112 MHz - CW, SSB, assemblage shared 14.112 to 14.350 MHz - SSB 14.225 to 14.235 MHz - SSTV Return to Top 21.000 to 21.070 MHz - CW 21.070 to 21.090 MHz - Digital Modes 21.090 to 21.125 MHz - Packet 21.100 to 21.150 MHz - CW and SSB 21.150 to 21.335 MHz - SSB and other broad-brimmed band modes 21.335 to 21.345 MHz - SSTV 21.345 to 21.450 MHz - SSB and other wide musical organisation modes Return to Top 28.000 to 28.200 MHz - CW 28.070 to 28.120 MHz - appendage Modes 28.120 to 28.190 MHz - Packet 28.190 to 28.200 MHz - Beacons 28.200 to 29.300 MHz - SSB and other bird's-eye lot modes 29.300 to 29.510 MHz - Satellite 29.510 to 29.700 MHz - SSB, FM and repeaters Return to Top Footnotes: 1) In northeastward America the following frequencies are suggested for package digipeater and parcel strewing operation: 50.62/51.62 50.68/51.68 50.76/51.76 50.64/51.64 50.72/51.72 50.78/51.78 50.66/51.66 50.74/51.74 For co-located vox and mail boat repeaters, use high (input) and low (output) to provide maximum mutual frequency isolation. 2) TABLE OF REPEATER PAIRS 3) AMATEURS ARE REQUESTED TO AVOID USING FM OR OTHER WIDE BAND MODES ON THESE FREQUENCIES TO downplay INTERFERENCE TO AUSTRALIAN AND NEW ZEALAND AMATEURS WORKING INTO part 2 ON SSB/CW.
Communication technologies that are specifically intentional to improve "live" HF device action can now be achieved which were antecedently only theory, too complex, or too costly to implement to be practical. Thanks to the share-out of wireless amateurs (hams) with programming knowledge, and to the Internet, new and efficacious communications tools are available to all hams. The phylogeny and wide ranch use of the Personal information processing system that consider a digital sound positive identification for member sign Processing (DSP), is allowing broadcasting amateurs to use these tools to develop new modes of member communication.
