Abstract
By analyzing an oblique ionogram several characteristics, such as LOF, MOF, FMUF, FHLOF, FLLOF, and 2FMOF,
can be found. These characteristics are important both for ionospheric studies and for terrestrial communication purposes,
as they give information about the sky wave communication conditions in the High Frequency (HF) radio spectrum.
A RCS-5B sweeping HF receiver for oblique sounding was installed at Chania (Crete, Greece, 35.71N, 24.01E) in April
2005 to perform a radio link with Inskip (UK, 53.51N, 2.51W). The receiver, able to record the sounding only as a binary
file, was not equipped with a tool to display and scale the recorded trace. This work describes software that is able to do
this, consequently increasing the speed of the scaling phase performed by the operator. The usefulness of this software for
validating FMUF prediction models is also shown.
