For some years there hasn't been an Ultralight review with the
newest receivers. Some contributions to the list let me doubt if the
original definitions are still strictly adhered.
I like the Sony SRF-18 very much for its barefoot sensitivity, that is among the best. Measuring the radio is not quite easy due to its
curved outlines. I guess it is slightly above 20 cubic inches. Can
it still be considered as an Ultralight?
