Graeme Is this even possible with an antenna connected considering atmospheric noise, or is atmospheric noise very low in the Southern Hemisphere and Australia? Regards, John Byrns The sensitivity figure was intended to be 1.0 microvolt. I've corrected the message and included it again below. Thanks for catching it John. Graeme Corrected message: Am looking for a reasonable cost BCB (MW) superhet tuner or receiver (valve or solid state) which has a known sensitivity of 1.0 microvolt or less for 10 dB s+n/n ratio. May be a manufactured or kitset radio, or a magazine project. All advice and references appreciated. TIA. Graeme |
