National Satellite radio system performance in the to MHz VHF meteorological satellite band is compromised by man-made noise external to the receiver. Methods used for predicting man-made noise power in this band are based on measurements conducted in the 's. These methods may be inaccurate due to technological advances such as quieter automotive ignition systems and the ?pub=   Corpus ID: Measuring Noise in the VHF Band and Its Effect on Low SNR Signal Detection @inproceedings{DeJarnetteMeasuringNI, title={Measuring Noise in the VHF Band and Its Effect on Low SNR Signal Detection}, author={Hunter Archer DeJarnette}, year={} } Man-made noise measurement programme.

measurements performed by ITS in the to MHz meteorological satellite band indicated that man-made noise power in residential areas is lower than predictions by these models. However, these same measurements indicated that man-made noise in business areas has not changed. UHF man-made noise has not been comprehensively measured and ://?id=TRpdf.

Today (), most activity is restricted to MHz (which is the current allocation) and consists of meteorological satellites transmitting data and low resolution images, together with low data rate mobile satellite downlinks (eg Orbcomm) The BaoFeng UV-5R is a compact hand held transceiver providing 4 watts in the frequency range of MHz and MHz. It is a compact, economical HT that includes special VHF receive band from 65 - MHz which includes the regular FM broadcast band. Dual watch and dual reception is ://
