The CONTOUR, and the APF, are very effective receiver noise reduction tools in the HF bands operations. Also: the AUTO NOTCH (DNF) automatically eliminates the dominant beat tone. The 32 bit high speed floating Point DSP (max 3000 MIPS) provides effective cancellation/ reduction (DNR) of the random noise that is frequently frustrating in the HF frequencies. IF DSP provides effective and optimized QRM rejection TCXO provides ☐.5 ppm High frequency stability ( 10☌ to +50☌).
3 kHz roofing filter equipped as standard.
