Welcome to these pages
where you will find information about my first
steps into 4 metre operation. At the
moment it mainly comprises of the antenna!
4 metres (70MHz) appears to exhibit many of the same characteristics of the
2M (144MHz) and 6m (50MHz) bands. In the short time of looking at
this band I have discovered that the band is affected by tropospheric lifts and temperature inversions but
seemingly at a lesser extent than 2m. I have experienced Sporadic E
enhancements and now that many other countries have access to the band it
is fun on a band that it much less crowded than 6m. Sporadic events can be
prolonged and very strong. Under normal conditions I have found the band to
be slightly awkward to use with deep fading at times, distances at this
station appear to range from a nominal 100 miles to 300 under normal
conditions.
All modes are used on the band and although there currently is no space
communications there is a very good opportunity to work meteor scatter.
At the present moment the band in the UK band allows a maximum power level
of 22DBw (approx 160w) and the band edges are 70.000MHz to 70.500MHz.
More information is given in the band plan which may be clicked on from the
