High Performance VLF / Longwave Up-Converter

High performance Longwave up-converter, hears VLF right down to 1KHz! Ultra sensitive and low noise; on a simple antenna you can receive JJY on both 40 & 60KHz along with other distant VLF signals right here in Australia !

Excellent for listening to VLF phenomenon such as whistlers, sprites and for SID monitoring.

The Up Conversion places the Longwave Band 1 to 500KHz within the 10.0 to 10.5MHz Band)

Designed to completely block AM/MW Band Interference and reject inband reception of Shortwave signals on the converter output.

12 Volt operation with Relay Bypass on the input and output on power off.

(Order Code: C-CONV-LF10 for 10MHz O/P )
