Hi,

I looked at those Koolertrons and considered getting one before I bought my Siglent.

Sure, they cost a lot less than a Siglent (which is also made in China), but are they as good?

I honestly do not know.

I can tell you, though, that this will require inline attenuators, as did my Siglent, to provide usable signals to a vintage radio.

I will let the folks on here who know more about signal generators (looking at you morzh, RadioRoslyn, BrendaAnn, Dale) comment further on this subject.
