Propagation Logger
This site contains propagation reports for 6 Meters (Magic Band),
2 Meters, 220 mHz, 440, TV / FM, SWL and other bands as well. The
list contains current reports in a short message format and also
accepts new propagation report submissions from visitors. In
addition, there are a bunch of links to other websites as well.

FCC lookup information
(not callsigns)
Have you ever wanted to know what frequency is assigned to a
particular TV channel, FM channel or vice-versa? This site also has
many conversion programs that run "online" - Metric to English
distance, Field Strength (dBu to - from mVm), kW to-from dBk,
Relative field values for direction pattern, transmission line
efficiency, Electrical degrees to-from meters conversion program ?
This link points to the "non-callsign" FCC database which can be used
for these RF lookup lists - please

Conversion tables / unit conversion online
Looking for a conversion chart? You've found the right place.
Here you can make online conversions
(e.g.
metric conversions)
for many measurement systems either common (U.S., metric, etc.) or quite exotic like
Ancient
Greek and Roman. You can also ask your questions and discuss how
to convert units on our Units Conversion
Forum.
Convert-me.Com helps you easily convert weight, convert length, convert various measurements.

The NOAA Space Weather Scales were introduced as a way to
communicate to the general public the current and
future
space weather conditions and their possible effects on people and
systems. Many of the SEC products
describe the space environment, but few have described the effects that
can be experienced as the result of
environmental disturbances. These scales will be useful to users of our
products and those who are interested in
space
weather effects. The scales describe the environmental disturbances for
three event types: geomagnetic
storms,
solar radiation storms, and radio blackouts. The scales have numbered
levels, analogous to hurricanes,
tornadoes, and earthquakes that convey severity. They list possible
effects at each level. They also show how often
such
events happen, and give a measure of the intensity of the physical
causes. Click here.
