Mike,
I'm using a Kenwood TS440. 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)

Citeren Mike Dennison <[email protected]>:
I am compiling a list of receivers and transceivers suitable
for 136kHz. I know most of the older radios already but
does anyone use a radio made in, say, the last five years
that they use sucessfully? If so, does it need an LF pre-
amp? Is the noise blanker any good on LF QRN and/or
Loran? Is a narrow filter fitted as standard?
Your help would be appreciated.
Thanks
Mike, G3XDV
