    Details:

    TECSUN Handheld Portable Wireless Satellite Radio S-2000

    • The Grundig Satellit 750 (as it's known in North America) is manufactured by Tecsun in China. It is sold as the Tecsun S-2000 inside China. For the rest of this report we will use "Satellit 750", but for the most part the text is vaild for the TECSUN S-2000 as well. Oh yes, elsewhere in the world it's known as the eton "Satellit 750"..(whew)
    • One may wish to compare this model to the older Satellit 800 model. But unlike the elder e1 model, Drake's fingerprints are absent from this entry and it shows. No synchronous detection, and a SSB mode that is lacking due to a too wide of a "narrow" filter and poor AGC. The audio quality is most pleasant for broadcast stations and overall is a most enjoyable larger portable. However as we cover in the report below, the wobbly tuning knob and almost useless S-Meter ruins the charm for me. It is certainly no Satellit 800 or e1

    No Gap LW- MW- SW Frequency Coverage

    The 750's receive coverage is :

    • Long Wave: 100 to 519 kHz
    • Medium Wave: 520 to 1710 kHz
    • Shortwave: 1711 to 29999 kHz
    • FM Broadcast: 76 to 108 MHz
    • Aircraft: 118 to 137 MHz
    • The FM band limits are toggled in the "System Code Settings"menu . Either as 76 to 108 MHz or as 87 to 108 MHz

    TECSUN Handheld Portable Wireless Satellite Radio S-2000

    Strange Sized Package with a Cubby Hole In The Rear / Negative Tip DC Input Polarity / Hum Using Included AC Adapter with Whip of Indoor Antenna. Ergonomics OK / Reset Button

    • Approximate size of the 750 is 14.6 x 7 x 6 inches (length, height, depth). The approx. measured weight without batteries was 5 lbs 6 oz (6 lbs 14 oz with batteries installed)
    • At least in the case of the 750, a strange compartment is found in the rear , right next to the battery compartment (with it's own separate lid). It's internal size is approximately 2 1/4 x 2 3/4 x 1 ½ inches. The lid to this mystery cavity has a what looks to be a line cord cut out in it ? It appears that somewhere in the design stage a internal AC cord may have been in the works (or perhaps with other variations of the model) ? In fact the Tecsun S-2000 version does appear to have a internal 230 v ac supply. The Grundig 750 only uses a external wall wart via it's DC jack
    • With the tested Grundig version (USA 117VAC), a UL listed unregulated wall wart rated at 6 volt at 500 milliamp current rating was included. It works properly, but as is the case with may of these power supplies we heard hum induced with SW signals when the whip or a indoor antenna was used. Once connected to a outdoor antenna this was not an issue. WARNING : The un-standard "negative tip" is being used with the DC input jack
    • Ergonomics are OK. The knobs are a bit tightly placed and are tiny for a larger radio. So for anyone with larger fingers may have a problem here. Memory entry and access are not the easiest either. Of course there are no single touch buttons for memory access
    • There is a nice handle that folds out of the way, a huge plus over the e1. 4 stuck on rubber like protection pads are on the bottom to keep it from sliding around. No tilt bail of any kind is to be found on the 750. One can take the "little pinky" finger and push in the speaker grill (in the center) with no problem, so pretty thin plastic here (that's right no metal speaker grill being used)
    • A reset button is located in the lower left hand corner of the tuning knob. This is to help to get out of lockups (which did not occur during testing). But can easily be selected by accident. Good news is that it does not bother the clock or memory entries. One just has to renter the "System Code Settings"

    TECSUN Handheld Portable Wireless Satellite Radio S-2000

    Antenna Connections / Top Mounted MW Loop-stick Scrapes Cabinet

    • 2 BNC connectors are located on the right side of the cabinet for connection of FM and SW external antenna's. Also a 500 ohm speaker terminal for connection to SW high impedance antennas. There is a switch next to these jacks to select between the whip and the external jacks
    • These of course are a bit un-standard for a SW set to use BNC type antenna connectors. No adapters are included. This does allow for a faster "unplug and go" affair over the PL-259 variety
    • On top of the set we find a 8 inch long 360 degree rotatable LW/MW "loop-stick" antenna. As it's rotated it "clicks"
    • [Update : This click all but disappeared with only light use from new.]
    • We also found if the antenna is slightly pushed down at all during rotation the bottom of the loop-stick case will scrape on the top of the radio's case
    • Also we found one spot in rotation with the test sample where it seemed to be a dropout (bad connection) and a small pop was heard from the speaker. But this was not of any real issue here. The LW and MW bands do have a seperate "external" antenna jack located on the loop (untested)

    TECSUN Handheld Portable Wireless Satellite Radio S-2000

    Wobbly Tuning Knob With "Rubberized" Paint / Buttons OK / LCD Display-Contrast-Lightning / Real Old Style S-Meter But Over Reads and Recessed

    • The "push on" style tuning knob is on the larger side , It has a finger spinner hole (it does not rotate), also appears to be some added weight installed. It spins most freely too without any hesitation
    • However , just as it was with the early Sat 800's, we have a nasty amount to play that makes one wonder if it is a tuning knob or a joystick ?? This makes the set MUCH less appealing
    • With the black ring on the knob we were thinking, "a neat rubber grip track around the outer side of the knob". Not so fast.......as it turned out to be nothing more than some of that Chinese "Rubber Feeling" paint in use here. Of course it has the potential to wear away with use
    • The 750 has a real mechanical s-meter. Readings appears way to generous on MW and SW. On FM it's either full scale or nothing, so even worse here. So it's not very useful afterall. Also it's very dimly lit (only one dim LED) and is recessed back in to make it almost useless. It's not easy to see in any event
    • LCD contrast is good as long as you view in from the top. Looking at it straight on it's weak. General main LCD brightness is OK, but could be a bit brighter and more evenly lit. There is only one brightness level
    • You are able to toggle the LCD backlighting for continuous operation. However it does not remember this setting, so you have to push and hold the light/snooze button for a second every time you turn it on to make the display backlighting stay on all the time in use (other wise it's a 3 second timed thing when a knob or button is pressed)

    Alarms / Sleep Modes / Snooze

    • Sleep mode is provided and is selected as it should with it's own button. Has no forced on selection. It can be set for 01, 05, 10, 15, 30, 45, 60 ,75, 90, or 120 minutes
    • 2 timers/alarms are featured. You have the choice to have either radio or buzzer (it's really a beeper). The off time are the same selections as the sleep timer above. LCD icons provide the status of both of these. When the radio is turned off the clock is displayed where the frequency was and the alarm times are displayed were the clock display normally is (it toggles back and forth showing both "on" times)
    • Additionally there is a 10 snooze function

    TECSUN Handheld Portable Wireless Satellite Radio S-2000

    No Strange Noises / Great Image Rejection / Some Cuffing But No Muting / Tuning Methods - Steps / 1000 Memory Channels / Lock Is For Dial Only / ATS on FM, LW, MW
    Receiver is clean with no strange spurious noises or groans. Image rejection is decent too. None noticed in testing. There is some chuffing when tuning , but lacks any muting nasties

    TECSUN Handheld Portable Wireless Satellite Radio S-2000

    The TECSUN S2000 has just about every tuning method available. Of course there the direct access keyboard. The enter button is not required to be used in most cases. Just key in the frequency in kHz and BOOM it pops in, no other buttons prior to the direct entry are needed either . If you wish to enter say just 6 MHz. Hit the 6 and the enter key and 6000 kHz is there. Does not get much easier here

    There are 1000 total memory channels. These are banked in 2 chunks and the how the pages are configured depends how the "System Code Settings" are configured (to the owners desires). These are not the easiest to enter or access however

    • 10 Pages, each with 50 memories
    • 20 Pages, each with 25 memories
    • 25 Pages, each with 20 memories
    • 50 Pages, each with 10 memories

    You can scan up and down the band stopping at a channel for 5 seconds and then it continues on (just like on a car radio). Works on all bands. You can also do the same scanning method with memory channels as well. It works well too and is most useful for lazy band scanning
    ATS feature is useable on LW, MW or FM bands and is stored in Page 0 (P0)

    TECSUN Handheld Portable Wireless Satellite Radio S-2000

    Great Audio Quality With Separate Bass and Treble and a Beefy Speaker, But with a couple of Bug's

    • The 700's audio is a aural treat with it's beefy sized speaker and separate Bass and Treble controls. It does sound nice and if one can use the "Wide" filter for a given SW or MW station, then it becomes very nice indeed
    • But it's not all wine and roses. First with very strong stations on SW or MW, there is a noticeable amount of distortion the creeps in. Adjusting the RF Gain control helped to reduce this, but this was never a 100% cure all. We were never able to put a handle on what was going on here, but it appears that a AGC bug may be the issue here (that is maybe running out of steam) ??
    • Next, MW and SW sounds a shade on the dull side. It doesn't have the sparkle on the high frequency end in the audio even with the Treble on at full. FM band doesn't have this restricted sound

    TECSUN Handheld Portable Wireless Satellite Radio S-2000

    Great SW Sensitivity / Average MW and FM / Aircraft Band a Disappointment / Dynamic Range Respectable

    • Sensitivity on SW was very good or better. Whip antenna or external antenna. Dynamic range was equally good as well, never launching into overload in the testing period
    • On MW sensitivity is good, but not to any way above average levels. The top mounted 360 degree rotatable LW/MW "loop-stick" antenna certainly helps with reduction of local interference or with other stations (has a good null factor), but as far as a "hot to trot" DX machine on MW, it was simply is not there with our test unit
    • We also found the hand placement can make operation of the MW loop-stick a bit daunting. Sometimes (but not always) once the user moves the hand away, the null point changes. Touching the loop only at the ends seemed to help here
    • FM is in a similar boat. Sensitivity is only at a average level, and we found the FM in the Degen DE1121 to out perform the 750 for FM sensitivity
    • The real downer with sensitivity on the 750 lies with the Aircraft band. It was a total disappointment not even being able to pull in the local "ATIS" station on 128.250 MHz. This is perfectly receivable on the worst of receivers here for Aircraft (Yaesu VX-2R Amateur handheld on a short rubber antenna), and not a peep from the 750.....nothing

    TECSUN Handheld Portable Wireless Satellite Radio S-2000

    Separate USB-LSB Modes...But...../ Stability OK / Manual ECSS

    • The 750 has separate LSB and USB selections. However we were able to tune USB signals in LSB and USB in LSB mode. Mind you it was a bit easier to tune when the proper mode did match the radio setting. But being we have a SSB BFO marked knob, this really tells the story here
    • Mind you the stability all around is good. But for another reason the SSB quality lacking is with the sound of it. A bit of warble and the AGC seems too fast to proper SSB (so one hears nasty pumping). Again the narrow filter is a bit too wide for serious SSB use.
    • We tried manual ECSS with little success. It was difficult to keep any station in sync for any length of time, and was hard to tune using that BFO control. Forget it
    • Long Time To Change Batteries Before Reset / Memories Not Battery Backed ?? / No 12 kHz output for DRM as Planned / Owners Manual Printed In Light Gray Ink
    • Due to time frame issues with the sample loaner , we were unable to test if the memories are battery backed up ?
    • But we did leave the set up unplugged for a good 12 hour time frame, and the clock and memories were was still storing all. The LCD fades out in about 2 hours from the screen, but is retaining the clock counting. Again was unable to see how long the clock went before it died (and would be a tough one to unearth as the display dies in a few hours, but the clock is really still counting. No way to tell when the clock actually dies.)
    • A 12 kHz output for DRM (for connection to a computer) that was given as a feature in eton's pre-production ads. This is one jack that was not found on the test sample. So appears this went MIA before actual production
    • The skimpy multi-language owners manual's text is printed using "light gray" ink. This makes for ruff reading. It also barely gives enough information on how to use the receiver

    How to Increase Radio Clarity on an AM/FM Portable Radio:

    TECSUN Handheld Portable Wireless Satellite Radio S-2000 

    • Check the antenna's connection. The hinges on older portable radios may weaken over time, so if the connection to the radio body is flawed, it may prevent the signal from adequately entering your radioExtend the antenna. FM antenna signals travel in straight lines, so if there are any obstructions like hills or tall buildings, your radio may have a hard time receiving enough signal for clarity. The telescopic antenna on your portable radio will not have an effect on the reception of AM signal.
    • Rotate the radio. Turn the radio on and switch it to its FM function. Cock the antenna slightly to one side and slowly rotate the radio body around to find the best signal. Because FM signals travel in straight lines, if the antenna is pointed away from the signal transmitter at the radio station, it may make the reception unclear or fuzzy
    • Take the radio outside. AM broadcasts can be seriously disrupted by electrical interference, especially within cities. Power lines, street lamps and household electrical appliances can interfere with the clarity of AM radio signal. Try to find AM signal at a different time of day. AM signals will travel farther at nighttime, although their coverage area may be reduced
    • Tune the antenna to a local station. The radio will receive clearer, stronger signal from stations that are closer to you. Replacing the antenna with a longer one could also help increase FM signal clarity
