NRD - 1107D
überarbeitet am 19.10.2010
The NRD-1107D is an easy-to-use professional grade maritime communications receiver covering the maritime communication shortwave bands only.
The NRD-1107D is a professional grade maritime communications receiver in 19 inch rack format, I suspect, it was originally built for 110 V, mine has been adapted for 230 V AC use.
The frontpanel is clearly structured, as with all JRC equipment.
Because of the selection of available bands, You can recognize easily, that the
NRD-1107D has been built for maritime communications use, most of the broadcast bands
and amateur radio band segments are omitted.
The NRD-1107D has no internal speaker, the NF signal is provided from a multi-pole connector at the receiver's rear panel. You also find a SO-239 antenna socket and an earth connector at the back of the set.
Operation of the set is really uncomplicated: Switch it on usind the AF gain control, AGC should be set to ON, to catch Deutsche Welle set the modes switch EMISSION to A3A, BAND switch to 6, use the knob below the digits tu tune the receiver to 6 0 7 5.0 and You can listen to the news from Cologne. To tune in RAF Volmet on 4722 kHz use MODE A3J, BAND 4, the frequency digit knobs to 4 7 2 2 and there You are...
The set has several shortcoming for the shortwave listener: the main problem is tha fact, that this set is not general coverage! A tropical bands DXer will find all necessary bands, the set is not well suited for amateur radio fans. The lack of a main tuning knob to sweep the bands and the lack of memories are further shortcomings. There are no means to "postprocess" a signal, no passband tuning, notch filter, and so on. But the stability, sensitivity and dynamic range of this set are very good.
