The narrow IF setting is also helpful in pulling out a signal suffering under heavy noise. Pressing Time changes the frequency to the clock momentarily. A more serious assignment to sweep a professional office for a suspected listening device made the X Sweeper a logical choice. Page of 15 Go. Compared to the fractionalmillivolt sensitivities of scanners and receivers, this is relatively deaf, but is necessary to reduce unwanted hits from distant signals.
Using Antenna SW antenna. Everything works well, from the sleep timer and alarms to the tuning knob and SSB fine tuning.
DEGEN DE1103 Operation Manual
Once you fine tune mannual SSB signal, usually no further adjustment is necessary. Tuning up 49 meters, there are no ed1103 of the spurious signals of RT or gospel stations in the background, as there are on single conversion units.
Turn jog dial wheel to adjust minutes. Don’t show me this message again. The BBC on usually has no interference, and the band is quiet on adjacent channels.
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 sweeping, acquiring and memorizing active frequencies in that entire range in as little as one second.
Intermediate-frequency IF Selectivity is quite broad nearly kHzdictating that the unit will respond to the strongest and presumably the closest signal in its passband. Your positions on each of the 12 bands on the dial face are remembered, unless you switch to memory mode, when they are effaced by presets. Manyal of Contents Add to my manuals Add.
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. Further, the meter acts as a battery level indicator, to show how much charge is left in the cells.
Many interesting emissions from modern office fe1103 were revealed but no bugs were found! If you get a DE, be aware that the factory set and reset volume level is 40 it comes on in FM.

But when a band is quiet, some chirping can be heard with each 1 kHz step. At night on MW, a station is audible almost every 10 kHz with just the internal antenna. Don’t have an account? Still, the buttons are small, and your hand has manua, move around to find them, where the usual keypad format requires almost no movement and provides easy counting.
Alternatively, the unit can be operated by user-provided and externally-recharged NiMH or NiCd cells. Typically, the Sweeper responds to signal levels above 20 microvolts in the MHz range, increasing to microvolts at 1 GHz, and 40 millivolts at the top end 2. To tune to frequencies outside these bands, you must enter them, or a memory, directly but coverage is complete, from kHz. Contrast can be adjusted by a simple key press.
I always use the wire indoors, though just about all stations come in using the whip. The sound will be somewhat muffled and an increase in volume will be necessary, but the interfering signal will be drastically reduced or eliminated.
Scanners can slowly sweep and memorize search-discovered frequencies for later recall and monitoring, but have no wide-span spectrum display. 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.
After setting, press to confirm.
The whip is fairly thick and heavy duty and de11103 whole unit is solid. Presets numbered can be accessed through de103. The 64 x LCD is backlit for night viewing, and is strongly visible in direct sunlight as well. Unlike many scanners that inaccurately display search-discovered frequencies slightly high or low of their actual carrier frequencies, we found the X Sweeper to have an excellent window detector that accurately displays intercepted frequencies to 4 decimal places specified accuracy of Hz.

Many of these were intriguing and all had tuning knobs, but none of them read out to the last frequency digit. Press any button to stop auto scan tuning. This feature is the way to at least partially overcome the lack of a standard keypad for groggy bedside operation: 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. My normal listening volume is between 8 and 12, 20 at the most to fill the room.
Slide the battery lid. Not only is the dial face illuminated with an amber glow, but all of the front buttons are, too. Enter text from picture: Adjusting the squelch knob to a looser setting reduces the false hits, amnual decreases the low sensitivity even further.
Detailed specs of the and Degen line can be found at: Optional antennas are available from Manal, but the standard BNC connector accepts an endless number of widelyavailable antennas.
