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.
