Introduction of 60m amateur band Chu Haoyuan 9V1HY

History The 60 meter band or 5 MHz band was first introduced in 2002 in a few contries. At WRC-12, Resolution 649 was ratified as being placed on the Agenda for the following WRC in 2015 (WRC-15). This resolution invited WRC- 15 to consider "Possible allocation to the amateur service on a secondary basis at around 5300 kHz (5275-5450 kHz)". At WRC-15, a worldwide frequency allocation of 5351.5–5366.5 kHz to the Amateur Service on a secondary basis. 5.A14 Stations in the amateur service using the frequency band 5351.5-5366.5 kHz shall not exceed a maximum radiated power of 15 W (e.i.r.p.). ......(WRC-15) The ITU allocation comes into effect from January 1, 2017

Countries with 60m allocation Offical allocation Experimental Emergency Specific operations

Countries with 60m allocation In region 3: Australia and New Zealand - Emergency only Bangladesh - Experimental Samoa - Follows US Hong Kong

Band plan US: 5 channels 5330.5 5346.5 5357.0 5371.5 5403.5 kHz UK: segments between 5258.5 - 5406.5 kHz Other countries have different band plan between 5250-5450 kHz

Band plan Worldwide: 5351.5–5366.5 kHz, 15W EIRP 5351.5-5354 5354 5357 5360 5363 5366-5366.5 CW, narrow digital modes USB, All modes Weak signal, narrow band 200Hz 2.7kHz 20Hz ↑ UK channel ↑ US channel ↑ UK channel ↑ DATA

Propagation Lying approximately halfway between 80m (3.5 MHz) and 40m (7 MHz). Often needed in emergency communication scenarios. Less affected by D-Layer absorption than 80m.

Propagation Ideal candidate for Near Vertical Incidence Skywave (NVIS). Local-to-medium distance HF communications (>200km). Information about the Critical Frequency (foF2) of the Ionosphere at any one time is highly important for setting up and maintaining reliable NVIS radio links.
