    Ebay and amazon are full of these function generators

    http://www.ebay.co.uk/itm/0-01-5MHz..._Measurement_Equipment_ET&hash=item3a78bb6f8a

    Are they any good?

    I'd like to be able to generate rf frequencies mainly for recreating some of the stuff I've been learning about in theory and also to help me play with making simple radios.

    I've been looking at the Rigol DG1022 which looks like a good piece of kit- but it's 10 times as expensive as these pcb versions, and do I really need it?

    What do you all think?

    Nice to play with at LF for the money but RF no way.

    Look at the specs it says to 5Mhz but then

    Why are all the other specs quoted in the audio range?

    You would also need a buffer (vidoe) amp for this unit.

    Look into obtaining a copy of ARRL's Radio Amateurs Handbook.

    Note also the source / location of the item in your link... :eek: "Caveat Emptor" !!


    studiot raised some valid points to consider...

    Hello,

    As PackratKing said, you won't be dissapointed by obtaining a copy of the ARRL or RSGB handbooks.
    (I have both here on my desk).
    You could also have a look at my RF related links thread.
    There you will also find sites with "building blocks".
