ionosonde (Label) says:
The twelfth release of ionosonde recordings is all about dub techno on a micro scale. An analog synthesizers were used in this album which explored the the sonic wonders of the super high frequency (SHF) electromagnetic band where radars listen intently. This freqency rang goes by the name "the Ka band" or Kurz-above.
Using only analog gear to produce the best sound quality as posible, Telegraphy recreates sounds that might be heard by a person who's in control of one of these radars. Atmospheric noise mixes with the steadily cycling "on's and off's" of the radar signal, are mimic by synthesizers. Echo's from distant targets shows up on the view scope in the radar room, the same goes for Telegraphy as he echos his target chord.
With a compute only used as a MIDI source, Telegraphy produces ionosonde recording best sounding album
