136 kHz Projects - Pre-Amplifiers

136kHz L.F. Pre-amplifier by GØMRF
This circuit is based on a design by Dave Pick G3YXM and was jointly redesigned in 2003 after the original coils and polystyrene capacitors were made obsolete.

137 kHz antenna preamplifier by EA4EOZ
One of the principal problems an amateur operator finds when tries to receive in the 137 kHz band is the really poor performance on typical amateur transceivers.
