Hello Graham,
I use this rtlsdr with a lf converter with SBL1 to monitor the range from
4-140 khz,works very fine for such a cheap system!

Tnx Eberhard,
I think with post dsp processing the dynamic range is increased in
narrow window ? but in 3 MHz will be 42 ~ ?
There is a version of the software that enables use to be made of
the AD directly , needs the Rf feed to be attached to one of the
pins , not the main input , with then no need for the converter (not
tried yet as my original installation failed will need to remove and
start again)
but for £13 , not a bad system !
