Selectivity too is razor sharp typically offering greater than 90dB 5kHz SSB, almost 100dB 10kHz and greater than 100dB 20kHz, these excellent figures are achieved by the implementation of a remarkably low phase noise local oscillator with -158dBc/Hz 100kHz. All this and great sensitivity better than 0.5uV for 10dB S/N in AM mode and better than 0.3uV for 10dB S/N in SSB. Relay switching in the front end, not diodes, and the use of shielded inductors throughout the signal path. This fantastic strong signal handling is aided by the innovative configuration of a lateral DMOS FET QUAD first mixer running at 15V.

Intermodulation free dynamic range (IFDR) with the 2.2kHz filter is typically 105dB 100/200kHz spacing, 104dB 20/40kHz and still better than 90dB 5kHz. Where good strong signal handling, high performance and transportability are of great importance, the AR7030 is the solution offering an IP3 greater than +30dBm, typical +35dBm reduced by 10dB with the preamp ON. The self tuning variable bandwidth synchronous detector is a pleasure to use and hangs-on to the weakest of signals, audio quality is superb.

This plus the standard fitted TCXO makes the AR7030 ideal for ECSS applications. Four 455 kHz IF filters are provided as standard with provision for a further two, including Collins mechanical filters, all of which are self-aligned by the receiver for optimum performance and passband symmetry. Frequency coverage is from 0 (zero) to 32 MHz all mode: AM, Synchronous AM, USB, LSB, CW, DATA & NFM. High performance coupled to enhanced microprocessor features and facilities forms the cornerstone of its success.
