I was pleasantly surprised at the performance of these tiny, inexpensive units — pulling in African and European stations here on the U. Nothing beats the analog feel for bandscanning, but I still wanted a radio with digital precision for DXing.
I was holding out for the ideal radio which would meet my list of desired features: I was curious about manaul of the analogdigital hybrids, in which an analog tuner is fitted with digital readout. Many of these were intriguing and all had tuning knobs, but none of them read out to the last frequency digit.
It would be nice to have analog-feel tuning, but the 15 kHz manuaal frequency guesswork would hamper DXing. A huge plus was its scroll wheel which tunes in 1 kHz increments, and it was also fairly small.
The extreme portability of that set was almost a clincher plus it had a tuning knob, but the PL lacked the same things the YBPE did. Thinking maybe I could find an analogdigital hybrid which read out to the last kHz digit, I searched online and came up with the reverse: I thought it was clever, but apparently Sony experimented with a similar thing several years ago ICF SW40 without success.
While I was reading up on this radio which appeared to fulfill my manuall list, I noticed it was being sold on eBay for a low price. Honestly, I was so glad to be getting a digital radio with a knob which tuned in 1 kHz steps, many of these other features were extras to me. The Buttons The direct-entry digit buttons are in one row,beneath the dial face. This is an inconvenient setup when fumbling in the darkness at the bedside to enter a memory or frequency, where the traditional telephone-pad layout can mznual operated by touch.
Still, the buttons are small, and your hand has to move around to find them, where the usual keypad format requires almost no movement and provides easy counting. But this is the price for having the semi-analog dial face where a standard keypad would normally be. In the upper left corner are three buttons: Underneath the direct entry buttons are seven more buttons: The Jog Dial Probably the main thing to keep in mind when approaching this radio is to recognize the jog dial as the multi-purpose control it is.
The volume control is easily mastered. Pressing Time changes the frequency to the clock momentarily. The clock displays when the radio is off, and while charging, the signal strength meter doubles as a charging indicator, to show that charging is in progress. Further, the meter acts as a battery level indicator, to show how much charge is left in the cells.
And, with the radio charging, pushing CHG changes the clock to the number of charging hours left. The SW coverage of the semi-analog face is kHz: On SW it jumps in 25 kHz steps, so it reads anywhere from exactly on to 24 kHz off. When you reach the top or bottom of one of these bands, the needle snaps back manuql the opposite end of the band. To tune to frequencies outside these bands, you must enter them, or a memory, directly but coverage is de11033, from kHz.
Auto scan goes through the entire band on the dial, following the needle as it wraps around back to the top or bottom of the band. Presets numbered can be accessed through direct-entry. Any memory with a letter in its label from 0A to FE; there is no FF can only be accessed by the jog dial in memory mode.
Your positions de1013 each of the 12 bands on the dial face are remembered, unless you switch to memory mode, when they are effaced by presets. As you can see, deciding how to set and use your memories can be a confusing business. Memory scanning is accomplished by entering memory mode and de11103 turning manuual jog dial, which will run you up or down through all preset memories unset memories and all other frequencies are skipped. This feature is the way to at least partially overcome the lack of a standard keypad for groggy bedside operation: If you preset all your sleep time frequencies consecutively in a cluster in the memory, then enter memory mode, all you have to do is turn the tuning knob to carousel up and down through your group of chosen stations, without having to press a single button.
SSB For SSB janual, you tune to a SSB signal with the knob or by direct entry, punch the SSB button, turn the knob until the transmission starts to become intelligible, then adjust the fine tune dial for precise demodulation.
SSB is stable, and the fine tune dial feels smooth and solid. Once you fine tune a SSB signal, usually no further adjustment is necessary. Illumination With the light switch on, while running on batteries, the radio lights up whenever the jog dial is turned or one of the front buttons is pushed.
Not only is the dial face illuminated with an amber glow, but all of the front buttons are, too. The lights stay on for 15 seconds after the last turn of the dial or press of a button.
When running on AC power, with the light switch on, the lights are always on. To get the lights to come on without changing your settings, punch any of the direct entry digit buttons. Selectivity Selectivity is excellent on all bands. With the IF switch set to wide, I found the bleed-over ceased about 15 kHz up or down, at and If there were fair signals on andthey would be listenable with the narrow IF, though perhaps not on andbut Radio Thailand is extremely strong in my area.

Overall, the IF selector works like a charm, and is usually only necessary to separate stations which are 5 kHz apart. The sound will be mannual muffled and an increase in volume will be necessary, but the interfering signal will be drastically reduced or eliminated.
The narrow IF setting is also helpful in pulling out a signal suffering under heavy noise. Tuning up 49 meters, there are no traces of the spurious signals of RT or gospel stations in the background, as there are on single conversion units. Tuning with the knob mmanual smooth, probably as close to an analog feel as they could get it, with no muting.

But when a band is quiet, some chirping can be heard with each 1 kHz step. Sensitivity The has a very low internal noise floor, so that weak stations inaudible on a noisier radio will appear on the The BBC on usually has no manhal, and the band is quiet on maual channels.
Plugging in the included 35 foot wire and stringing it indoors gives a further boost. Radio Havana Cuba on also sometimes overloads with the wire.
I always use the wire indoors, though just about all stations come in using the whip. At night on MW, a station is audible almost every 10 kHz with just the internal antenna. Through the earphones, music on decent SW signals has rich bass.
Build Quality I was impressed with the feel of the cabinet, aluminum front, and controls of the The whip is fairly thick and heavy duty and the whole unit is solid.
The silver model especially has a nice finish and the bare aluminum face looks sharp. The dark model has a flat gray finish, with the aluminum face painted a matte milk chocolate color. One of the s I tried developed a faulty tuning shuttle, affecting all jog dial functions.
The dealer I bought the radio from says Degen claims to have ironed out the shuttle fault and improved SW sensitivity already extremely sensitive in their recent batches of s. My replacement from a new lot so far shows no problems, though the faulty radio took about two months to begin acting up.
Bottom Line There are a few changes I could recommend for easier operation, but overall, besides the direct entry button configuration and possible future tuning shuttle faults, I may have found my ideal radio.
Everything works well, from the sleep timer and alarms to the tuning knob and SSB fine tuning. Availability I bought my from eBay seller Mqnual, a gentleman in Hong Kong who, unlike some of the other sellers, offers a de11003 year warranty on the radio.
Tecsun is the parent company of Degen and Kaito, and they also manufacture a good part of the Grundig line at their factory in Hong Kong. Detailed specs of the and Degen line can be found at: If you get a DE, be aware that the factory set and reset volume level is 40 it comes on in FM.
My normal listening volume is between 8 and 12, 20 at the most to fill the room. I worry the 40 level is high enough to damage the speaker. It has to be done instantaneously with the buttons.
Optoelectronics X Sweeper By Bob Grove W8JHD O ne of the handiest gadgets for manhal frequency explorer would be a handheld device that not only manjal signal reception, but shows band activity on a wide-span spectrum display and also accurately reveals their frequencies.
Scanners can slowly sweep manuxl memorize search-discovered frequencies for later recall and monitoring, but have no wide-span spectrum display. Spectrum analyzers can manually be tuned to various portions of the spectrum to visually display signals and some have audio recovery, but they tend mmanual be large and expensive.
Now a prominent, American test-equipment manufacturer has released a faster device at lower cost. The new Optoelectronics X Sweeper expands technology embodied in a previous Opto product, their Xplorer, offering a continuous frequency range from MHz 3 GHz less cellular except on government modelsand manuual, acquiring and memorizing active frequencies in that entire range in as little as one second.
Apparently it accomplishes this quick sweep of a vast amount of spectrum through the use of a proprietary comb-generating variablefrequency oscillator, mixing a large number of separate oscillator frequencies simultaneously. A convenient although hard to openhinged, tilt bracket is recessed in the back, allowing desk-top placement at a comfortable viewing angle.
De11103 64 x LCD is backlit for night viewing, and is strongly visible in direct sunlight as well. Contrast manial be ,anual by a simple key press. Yet another selection can reverse the contrast from blue on white normal to white on blue. The backlight can be extinguished to extend battery life during high ambient lighting conditions. Up to 65, hits are recorded and reported by the memory which also stores frequency, signal strength, and a time and date stamp.
A separate log memory bank can store up to first- or last-sweep-discovered frequencies with their own reports.
Spans of frequency bands may be swept from user-selectable widths of 0. Alternatively, the unit will lock onto a search-discovered frequency for monitoring.
Typically, the Sweeper responds to signal amnual above manhal microvolts in the MHz range, increasing to microvolts at 1 GHz, and 40 millivolts at the top end 2. Compared to the fractionalmillivolt sensitivities of scanners and receivers, this is relatively deaf, but is necessary to reduce unwanted hits from distant signals. Intermediate-frequency IF Selectivity is quite broad nearly kHzdictating that the unit will respond to the strongest and presumably the closest manuaal in its passband.
Alternatively, the unit can be operated by user-provided and externally-recharged NiMH or NiCd cells. Its VDC power jack makes it a natural for long-duration mobile operation, identifying nearby signals as they are approached or passed. Alternatively, a 12 volt gel cell or other high-current, rechargeable battery in a belt or sling pouch would be a practical consideration maual extended portable operation.
Optional antennas are available from Optoelectronics, but the standard BNC connector accepts an endless number of widelyavailable antennas.
