Meteor Reflection Observations with RTL-SDR

YouTube user ek6rsc has posted a video showing one week of meteor scatter observation at 59.25MHz using the rtl-sdr and the HROFFT software. More information about meteor scatter observations can be found at the page of The International Project For Radio Meteor Observation. The rtl-sdr is handy as a cheap monitoring tool for purposes such as this. From Wikipedia meteor scatter is described as follows.

 Meteor burst communications (MBC), also referred to as meteor scatter communications, is a radio propagation mode that exploits the ionized trails of meteors during atmospheric entry to establish brief communications paths between radio stations up to 2,250 kilometres (1,400 mi) apart.

RTL-SDR Direct Sampling Compared with WebSDR

YouTube user opilarczyk has posted a video comparing HF performance of the rtl-sdr with the direct sampling mod at 7MHz with WebSDR, an online SDR streaming site. The comparison shows how the direct sampling mod is extremely susceptible to broadcast FM interference.
