Hi Iban, They do work, but you must realise they are not intended as =
radio receivers, and in many aspects their performance as radios is =
compromised by their design as line measuring instruments. Problems =
include IMD and lack of front end filtering, some lack audio output. Yes =
you can get round this or you can be lucky that you location and antenna =
help mitigate the problems. =20

You might be better to consider an SDR these days but make sure it =
really cover the frequencies of interest. Graham G0NBD has information =
on direct sampling mods to the DVT-B dongles. In Europe there are a lot =
more LF signals from very strong stations than in the US so be careful =
of US opinions that rate these as receivers. I have a couple of W&G =
units which while useful as test equipment are less than brilliant and =
barely worth their cost as receivers.

  Hi,


  I'm looking to purchase a 3586C. Somebody is using it?=20


  Can give-me feedback about to use in 136 and 477 kHz?


  Thanks for advance
