Well... You could do what Radio Jay Allan has done, and I have as well, it to swap the original little-ass bar antenna for a larger one. I've done that to two radios. The 1st being that Yorek YK-901 DSP $20.00 portable. With that one, I took a 3" bar antenna, from a burned-out 1960's clock radio and mounted that to a 5" EXT plastic stub, to keep the antenna away from the DSP chips. The results??? At least twice as good. Then, took the old 1.5" bar antenna from the Yorek, and mounted that in a DSP RCA branded clock radio, since that had a 1" bar antenna. Better AM performance on it by the work bench. So, you might do the same to a work-type Boombox from DeWalt, or Black & Decker. Now, to improve FM on those? Loose the 'lil stubby duck antennas for a 30" 1/4-wave telescopic whip. The work-type Boombox may not be a DX champ, but I'll bet there's big room for improvements there.
