I run my TS 440 on 1750 meters and noticed it has similar sensitivity as my
HP 3586C Selective Level Meter. Good to hear another person using it even
lower and still having good sensitivity.

Subject: Re: LF: Receivers
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
