TECSUN H-501x is equipped with an analog High-IF circuit and DSP triple conversion decoding technology. This radio receiver has great performance in sensitivity, selectivity and combating interference of mirror stations (image rejection). Like other Tecsun models it comes with a variety of “hidden features”.

The full-range dual speaker design, Class AB Amplifier circuit and independent treble and bass control knobs make listening to radio stations and the added audio playback feature (from a microSD card) even more enjoyable.

What is the difference between the H-501x and H-501?

	H-501x	H-501
LW range (kHz)	50-522* or 100-519**	100-519

SW range (kHz)	1621-29999* or 1711-29999**	1711-29999

FM tuning steps 87.5 – 108 MHz	50 kHz**	100 kHz

FM tuning steps other ranges	100 kHz	100 kHz

* Selected when the MW tuning steps on the H-501x are set to 9 kHz steps (Europe, Asia, Oceania, Africa).

** Selected when the MW tuning steps on the H-501x are set to 10 kHz steps (North and South America).
