I'm interested in the AM dial far more than anything else, so place an asterisk there on this recent purchase and evaluation of a Grundig S450.
Initially I bought it as a probable replacement for the GE SRII. The GE was a portable to bring along on roof and basement jobs by which to reach out regionally, past the locals. The thing could serve very well as a straight DX radio, as well. And that thing has fallen out of a moving car, along with toppling from every perch it ever occupied -- and still works well! Yet, I know it can't have too many of its nine lives left.
Even while driving home with the new Grundig in the car, I knew I wouldn;t like it for some reason. It was too light. It was too ... plastic. It had digital tuning.
And I was right. The S450's sonics were no match for the GE, separate treble and bass knobs notwithstanding. The GE picked up more stations louder and clearer in the day. I was going to ask for a refund, but instead asked to try out another S450.
This new one COOKS on AM! Sensitivity-wise, it might be a touch better than the GE, although I have no instruments or technical knowledge by which to gauge these things.
It does come with the 'field radio' boast, which to me is a mis-nomer. No 'field radio' should require external antennae for short-wave or FM.
And the fidelity remains nowhere near that of the GE. Perhaps with earphones it would be better. There also is a pumping effect to the AM reception on the weak frequencies. Perhaps that's the pushed-up signal design peculiar to some of those 'budget' communications receivers of the 60s and 70s, like the Lafayette HA700 and 600 had.
But the S450 does come with a gain control for AM, plus a narrow and wideband option switch.
And a clock, which is important on a roof job.
It's a keeper here. Clinching matters further: The past few days I've IDed a couple of those Mid-Winter Anomaly catches on it, barefoot.
