Page 12: Antenna Selection And Connection
4. Do not use a gas pipeline or AC power outlet for grounding purposes. 1. Long Wave and Medium Wave antenna: The S-8800 radio uses a built-in magnetic rod (ferrite) antenna to receive long wave and medium wave signals. Since this ferrite antenna is directional, minimizing interference and achieving the best reception for long wave and medium wave signals requires repositioning of the radio. - Page 13 AN-05 external antenna ” (can be purchased separately) to the telescopic antenna of the S-8800. Fix the opposite end at a high location outside the building, then push the [INT ANT. / EXT ANT.] antenna switch to “INT ANT.” position.

Page 16: Broadcasting Knowledge: How To Achieve Long-Distance Fm Radio Reception (Fm-Dx)
Broadcasting knowledge: How to achieve long-distance FM radio reception (FM-DX)? To enhance reception, use an outdoor VHF antenna or suitable FM antenna (low attenuation coaxial cable), fix it as high as possible (take into account the antenna usage safety alerts) and point it in the direction of the desired FM broadcast. If the signal is weak, you may require installing a low-noise antenna amplifier. -

Choosing a wider band (local stations / strong signals): It has better audio fidelity when receiving strong signals or local stations. Choosing a narrower band (long distance stations / weak stations): 1. Suitable for receiving weak and long AM Bandwidth display distance stations. -
Page 20: Fm Stereo
The figure shows an AM signal that has two sidebands with information, each a copy of the other, and the carrier wave. To enhance the efficiency of the signal, the carrier wave and either one of the sidebands can be eliminated. What remains is a single side band (SSB). -
Page 21: How To Reduce Interference When Listening To Fm Radio
2. How to reduce interference when listening to FM radio? - Change the length of the telescopic antenna: In general, when listening to lower frequencies (such as 89.3 MHz), fully extend the telescopic antenna. When listening to higher frequencies (such as 105.2 MHz), reduce the length of the antenna;... - Page 22 When using the remote control, in VF mode, you can directly key in the station frequency. Press the [M] button, then key in a memory location. Press the [M] button again to confirm.

Page 24: Broadcasting Knowledge: Why Are More Mw Stations Received At Night Than During The Day
4. For MW, due to the characteristics of radio waves, more radio stations can be received during nighttime than daytime. 5. It is advised to repeat the ATS function for SW from time to time, since SW reception is affected by a variety of factors. SW radio waves are affected by the condition of the ionosphere, which varies according to the time of day, seasons and the state of the sun. -

Page 27: Broadcasting Knowledge: Why Is The Sw Broadcasting Sound So Unstable, Continuously Changing Between Large And Small Sound
Broadcasting knowledge: Why is the SW broadcast sound so unstable, continuously changing between large and small sound? The cause can be found in the unstable nature of the ionosphere, which reflects SW signals back to earth. The height, thickness and density of the ionosphere influence how well SW signals are reflected, but these conditions change constantly, especially during daytime. -
