Reddit mentions of Kaito WRX-911 AM/FM Shortwave Radio, Blue

I had a KA228. I returned it after a few days because the tuner is digital with an analog interface (which was not explained in the product description), and fine tuning was basically impossible (which sucked a lot of fun out of the radio). Very sticky and jumpy, missed a lot of stations. I replaced it with a Kaito WRX911 (which is all analog and has a wider frequency range) for about the same price and am much happier with it, even though it does not have a DX/local switch and overloads easily.

That said, the sensitivity of that radio was pretty decent. I was able to pick up Radio Australia from Texas with it, and the very first thing I picked up with it was HM01 (Cuban numbers station), which you'll probably hear sooner or later during the day (somewhere between 9 and 12 mhz). The DSP also cleaned up the sound somewhat compared to this solid state analog WRX911.

Also, if you can stick with that radio for a while, your next upgrade will probably be to done that does SSB.

Finally, if you're getting a lot of local interference (from power lines, appliances, etc).. there are tons of different antenna designs out there to play with (invest in alligator clips to attach to your radio's antenna), but I've had pretty good luck making one of these with cardboard and aluminum foil (scroll all the way down to "The K3MT version").

Have fun!
