Sensitivity is very good at 136kHz. A small loop (1x1m) can be used without pre-amp, if I am using the TX antenna for receiving I need at least 30dB attenuation before the LF noisefloor is about 10dB above the RX noisefloor (so you are sure to have full sensitivity - you can hear any signal that comes out of the noise - and optimal IMD behaviour) 73, Rik ON7YD Citeren Mike Dennison : > I am compiling a list of receivers and transceivers suitable > for 136kHz.
