Noble Radio NR-4SC 4 Meter SSB/CW Transceiver</span></font></font></p><font size="3"><font color="#000000"><p>New on the market<br> The <strong>NR-4SC</strong> is a simple to use 10 Watt (minimum) 4 Meter SSB/CW transceiver. </p><p>The radio operates USB and CW. </p><p>The NR-4SC uses a single conversion design with an IF frequency of 10.7 MHz. Front end bandpass filters limit out of band signals into the RF Preamp stage.</p><p> A double balanced diode ring mixer provides good strong signal handling capability. There are two 8 pole crystal filters following the mixer which are designed for 3.0 kHz and 500 Hz -6dB bandwidths. The 3 kHz filter allows for good SSB voice fidelity while the 500 Hz filter provides good adjacent channel rejection on CW. Either filter can be selected in both modes.</p><p><img align="right" src="https://fbcdn-sphotos-d-a.akamaihd.net/hphotos-ak-xfp1/v/t1.0-9/10405445_804442012912653_3250036692388583566_n.jpg?oh=02e528be01d80a703a2bffe5aed718f3&oe=548498AC&__gda__=1418809381_bcbff5347dfa9d8e7ed28880cf98dd42" width="400">Two IF amplifier stages and fast attack AGC provide good re-ceiver sensitivity while leveling the audio output on strong sig-nals. AGC action starts at approximately a -120 dBm input signal level. </p><p>The local oscillator is derived from a DDS/PLL circuit pro-viding a high degree of stability and low noise. </p><p>A high stability 107.374 MHz reference oscillator is used for all local oscillator generation. The high frequency provides low DDS spurious out-put. </p><p><img align="right" src="https://fbcdn-sphotos-h-a.akamaihd.net/hphotos-ak-xfp1/v/t1.0-9/10622914_804441852912669_3721038170826765502_n.jpg?oh=4454ac506a46da4385b0a2d61520ca9a&oe=54889EED&__gda__=1418434148_1ae440a5ad44b6000a4de5ed827de9d7" width="395">The transceiver offers a 10.7MHz IF out on the back panel for connection to an SDR so it may be used with a PC for a Spec-tral Display.<br> Other features of the <br> NR-4SC include RIT (Receiver Incremental Tuning) and SPLIT mode functions as well as a built in Iambic Keyer for CW.
