Description :

The DE1103 is a compact, double-conversion super heterodyne, portable radio that covers FM broadcasting and the entire long, medium and short wave bands without gaps in AM as well as in SSB. Among the features: coarse and fine rotary control (for the SSB) tuning on the right side, by direct setting from the keyboard, with recall from the memories, with automatic scanning. Telescopic antenna for SW / FM bands, internal ferrite antenna for LW / MW between 100~1710 KHz, input for external SW antenna. Large LCD display with frequency / time indication, signal level / battery charger. A 12-band analogue scale with emulation of the mechanical style indicator. Illumination of the display and all the buttons with orange light. Switch between Local / DX in the LW / MW / SW bands with the insertion of an RF attenuator. Two IF filters for SSB and AM so as to adapt the bandwidth to listening needs. Two profiles audio tone control (Music and News). Auto-off timer in 5~99 minutes, two alarms with programmable power-on. Batteries compatible: alkaline and Ni-MH rechargeable. Integrated battery charger combined with the use of the external mains adapter. Audio outputs for headphones and recorder.

Performance and practical notes :

With this model Degen has created a receiver with a very good price / performance ratio. The sensitivity is indeed excellent with figures comparable to what is found in the mid-range desktop communications receiver. With the small DE1103 it is possible, in concrete, to listen extremely weak signals in the Medium and Short Waves. This especially in SSB opens to the monitoring of the amateur radio bands and utility services. Equally excellent, in relation to the type of apparatus, the dynamic-range that demonstrates low intermodulation phenomena even in the presence of strong signals and the use of an external antenna. This last element deserves applause to the designers because it is not common to verify such behavior. The bandwidth choice for the two medium frequency filters (IF) is well balanced, perfectly suited to the AM and SSB reception needs in the presence of emissions on adjacent channels. It is pointed out that the receiver is not able to distinguish clearly between LSB / USB, the user through fine tuning can in any case position the BFO on the side with respect to the center of the IF filter so as to accentuate the desired mode.
