Steffen shares some XHDATA D-220 tricks

XHDATA D-220 PortableMany thanks to SWLing Post contributor, Steffen Schultz, who writes:

Hello Thomas,

As a regular reader of your blog, I was fascinated by the reports on the XHDATA D-220 [affiliate link] and ordered a black one. I was not disappointed. Of course it’s not a DXing machine, but finally we have a device wich reaches the reception quality of the old pocket radios again I used to carry around in my childhood. I still have a Philips D1220 from the 80s, which is even less sensitive than the XHDATA D-220.

This reminded me of my early radio days, when I would try to use the simplest methods to manipulate analog radios to do things that were not intended by the manufacturer. For example, by moving the band selector switch to an intermediate position, it was possible to get some radios to receive frequencies outside the intended range. Of course, I couldn’t resist and experimented with the D-220. It takes a bit of patience and sensitivity, but the radio really does hold some secrets.

Medium wave reception with the telescopic antenna

When I was listening to a weak station on medium wave and slowly moved the switch to short wave, the medium wave station got louder for a moment before the slide switch clicked into the correct position. In fact, the radio seems to switch to the telescopic antenna when you move the band selector a little toward short wave. A finger test on the antenna confirmed my suspicion. I also tried connecting a long wire, but that was counterproductive with all the men-made noise inside my house. Extended shortwave reception

A similar trick can be used to change the shortwave frequencies. If you slightly move the band selector from the shortwave position towards medium wave, the receiver switches to a different shortwave frequency range, covering between about 3000 and 7000 kHz. Now I was able to receive shortwave radio from Germany on 3975 kHz without any problems, and of course South Korea via England on 3955 kHz was no problem either.

I have not yet found out if the two FM bands can also be manipulated in this way, an intermediate position of the band selector seems to have no effect here. Perhaps one of the readers has discovered something?
