i have an ats505. its a digital radio while the s350 is analog with a
digital read-out. i would expect the digital to win for over all
performance but analog has its useful qualities. this is like asking
whats better, apples or oranges. it depends on you and what you are
listening to. the digital ats505 will give precise frequency accuracy,
direct entry access to widely separated frequencies and quartz locked
stability. sw is one band from top to bottom without switching
sub-bands.it has single side band. its a good radio. its NOT a dx
machine. the s350 has analog tuning which CAN be an advantage
(sometimes) with weak distant signals. the digital display will generate
noise (like the one in the 505 does) and that will probably negate any
advantage that analog gets anyway. the s350 will drift off frequency
slightly over several minutes to an hour. frequencies must first be band
switched to the proper sub-band, ran up or down band to the frequency
and then fine tuned for best signal. all this sounds terrible but to us
old guys its like a breath of fresh air. analog has a personality that
needs to be learned. its performance is not bad, its different. the
grundig also has wide and narrow filters and D-cell batteries that
should last 6 months. it seems like a good (analog) radio too. it wont
be a dx machine either
