HF (HIGH FREQUENCY)

Brief over view of actives on the medium and short wave bands.


HOME  > OPERATIONAL >ACTIVITIES >

 

Contacts on all the H.F. (High Frequency) and M.F. (Medium Frequency) bands from 160M to 10M have been established using a simple multi-band dipole antenna that is capable of operating on all HF bands including the relatively new so-called WARC bands and to a more limited extent the 160 metre band. The antenna and radio are well capable of reception across the entire spectrum from around the 1. 8 MHz up to 30 MHz with a couple of relative dead spots due the difficulty of matching some of the extreme impedances presented at the ATU, but not near amateur bands.

The solar cycle is at low point as at January 2008, however there is still good activity on the lower HF bands of 80M and 40M. The use of PSK31 has allowed me to work the world with a modest antenna system running around thirty watts on both 20M and 40M.

Sir Ernest Thomas Fisk born 8 August 1886

Establishment of a Beam Wireless Service, providing the longest and fastest telegraphic communications in the world. The first such communication between Australia and England was in January 1927.

   Notice Board

VK6YSF JS8Call and Olivia 8/250 operations.

Current activity is generally focused - though not restricted to - JS8Call operations on the 30m, and 40m bands.

Olivia 8/250 is used occasionally on the 20m band.

Proposed band and mode activity is often communicated on HamSpots: https://hamspots.net/js8/ or my profile on
