The Global Ionospheric Radio Observatory (GIRO) Digisonde® network is rapidly expanding and the technical expert support for these many stations is becoming an issue.  Lowell Digisonde International, LLC (LDI) which is the sole manufacturer of Digisondes® since 2009, is therefore pleased to offer an “Extended Warranty” for Digisondes® for which the initial warranty has expired or will expire soon.
