I would never load another roll of strip-chart paper! My disgust and frustration gave way to resolve.
However, when the part arrived and I discovered that my $29.95 had purchased only another flimsy needle without installation instructions. Upon ordering a replacement part, I expected to receive a complete galvanometer needle mechanism for the quoted charge. Shortly thereafter, I accidently broke the needle on the Rustrak unit while replacing the paper. At the time of his article's publication, my SID monitoring system utilized a Rustrak recorder, and I didn't have a spare computer to dedicate to SID monitoring. Panzer discussed several desirable features of the Tandy unit such as its low noise, ease of operation and ready-to-run recording software. In a previous SID Technical Bulletin (April 1996), fellow contributor Alex Panzer described the successful interfacing of his VLF receiver to a computer via a Tandy Corporation digital multimeter.

Listen to KiwiSDR registered on the sdr.hu website.īrowser-based interface allowing four simultaneous user web connections.Įach connection tunes an independent receiver channel over the entire spectrum. Up to four people can listen simultaneously to one radio - each listener tunes independently. Both versions include software supplied on a micro-SD card.Īn HTML5-capable browser and internet connection will let you listen to a public KiwiSDR anywhere in the world. The KiwiSDR is available in two versions: the cape al one and a more complete version including BBG, enclosure and GPS antenna. You simply add an antenna, power supply and network connection. The KiwiSDR is a custom circuit board (cape) you connect to the BeagleBone G reen or BeagleBon e Black computer.
KiwiSDR is a software-defined radio (SDR) covering shortwave, the longwave & AM broadcast bands, various utility stations, and amateur radio transmissions, world-wide, in the spectrum from 10 kHz to 30 MHz.
