I. INSTRUMENTATION A. Vertical Sounding The IPS-42 Digital Ionosonde replaced the C-3 analog film-recording ionosonde. The sweep frequency is from one to 15 MHz. the ionosphere directly overhead is probed twice a day. B. Trans-Equatorial or Oblique Ionosonde Signals transmitted across the equator from MO and received in several southern stations reveal the changing characteristics [...]
