Depends on the intent Jim ?
A sound card would be as good as
anything for 9 KHz . as to 472/137 ,
other than CW & QRSS , there is
only one other use for a on off
keyed carrier I can think of , I would suspect one
of the DDS VFO kits would give
acceptable results , with the option to gps
condition the master oscillator , should the need
arise ?

Hi
All
As well as 2 W & G
level meters (SPM 3 and 19 & I agree with Alan ? marginal as Rxs) I
have a W & G PS60 (level generator). Has anyone any views/comments on
this item? I?m hoping to use it as a signal source for 137/472 and
possibly 9kc also. The latter to be run via ground loop electrode system
as per Roger G3XBM.
Any thoughts, comments
most welcome
Cheers

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.
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.

3586C selective level meter for LF and MF
Hi,
I'm looking to purchase a 3586C. Somebody is using
it?
Can give-me feedback about to use in 136 and 477
kHz?
