Radio Shack Pocket Shortwave Radio question

C

CurtisNEPA

I did a lot of research on this new pocket Shortwave radio from RadioShack. It's simply called a RadioShack AM/FM/Shortwave Pocket Radio(Model 2000669). I want to know would this unit overload with stronger signals when trying to listen to distant FM stations from 50-70 miles away. The Grundig G8 does not overload while DXing FM because it has a DSP chip embedded inside the unit. I had an older model of the RadioShack AM/FM/Shortwave radio (20-125) which has an LOCAL/DX switch, but when trying to DX a frequency during tropo openings, it gets overloaded by stronger signals. Unlike the G8, when trying to listen to a station adjacent to a local signal, it bleeds.(Both the G8 and the Insignia NS-HD01 has the ability to pick up a signal next to a local station, but the latter has FM overloading problem when living five miles from the transmitters). So before making a final decision, I need your input on this unit.

The full details of this radio is found here.

My guess is that is has a SiLabs chip in it. I have no facts to back that up, just a guess, as the analog AM-FM Pocket Radio (120-586) has a SiLabs chip in it. It's possible they're made at the same factory -- like I said, just a guess.

The AM-FM analog Pocket Radio 120-586 does not overload on AM or FM -- at least none that I've detected. And it is pretty good on FM, although it is mono. Sounds good through the headphone jack. So if the one you're looking at is using a SiLabs chip its performance may be similar. A lot of manufacturers are going DSP because of so few parts.
 
Followup...the RS does use a Silicon Labs IC...but
so did a couple of low cost Tecsun's that were also icky.
 
Too bad Jay Allen got the catalog number in his review wrong. The 200-629 is the Radio Shack badged SAngean ATS-505. Woops.
