Bill discovers a number of Tecsun S-8800 Hidden Features

Many thanks to SWLing Post contributor, Bill (WD9EQD), who writes:

I've owned a Tecsun S-8800 for about eight months and have come to enjoy it more all the time. It, along with my PL-880, have become my main work horses for shortwave listening.

The S-8800 is perfect on the desk connected to a wire antenna and the PL-880 is perfect for carrying around.

Since I knew of the hidden features of the PL-880, it got me thinking on whether the S-8800 had any hidden features.

A quick Google search turned up the following Web Page:

I used Google Translate to get a rough translation and then spent some time testing the features out and also just pressing and holding buttons to see if anything else showed up.

Following is what I have come up with:

(Note: some of these are in the manual)

With the radio off

Toggle Longwave on/off: With the Radio OFF, Press & Hold 2

Toggle backlight permanently on/off: With the Radio OFF, Press & Hold 3 - Note that this means the light will be on even when radio is off. While the light does go out when radio is turned off, any operation of a control will turn the backlight on and it will then stay on. Too bad they just didn't install a slide on/off switch. Plus I know of no way to turn the backlight on permanently without the remote.

Toggle Seconds display on/off: With the Radio OFF, Press & Hold 8

Displays "0888": Maybe this is version?: With the Radio OFF, Press & Hold "Back"

Displays all segments of display: With the Radio OFF, Press & Hold "AM NORM" - Displays all segments of display. Press & Hold again to display "H802"

With the radio on in FM mode

Displays "75US": With the radio ON, Press & Hold 5

Squelch Setting: With the radio ON, Press & Hold 9 - Range 0-5. Use Tuning Knob to set. Press 9 again to set.

With the radio on in SW/AM mode

Toggles Extended functions on/off: With the radio ON, Press & Hold 4

With extended functions on:

Press & Hold 6 - Toggles DNR (Dynamic Noise Reduction) on/off.

Press & Hold 9 - Squelch Setting. Use Tunng Know to Set. Press 9 again to set.

Squelch ranges:

MW: 0-40

MW with USB/LSB: 0-30

SW: 0-25

SW with USB/LSB: 0-30

So far that's all I've been able to find. Has anyone else found any others?

Post readers: please comment if you've discovered other hidden features on the Tecsun S-8800! I'll compile a complete list and post it separately.
