Re: 16.09.2020 An odd dark patch.

With the greatest respect, the spot remained fixed on the sun. Not in the field of view. I could use the drives to move completely away from the darker region and return to it as fixed point on the sun. In fact I was using the drives as usual to centre "the blob." Which would be impossible with a d...

Hi Rainer, I would say this is a success. Excellent! Spectrum Lab should also provide a log of each event for you to plot out, which you can do using Excel. Stu.

Re: Perseid Meteor Detection by Radio

Hi Stu, Thank you. Looks like I am doing some progress with my chosen frequency at 180 MHz tuning on the ATSC pilot carrier +310 kHz. Here some pings extracted from my 10 hour video. What do you think ? Some are debatable but the time is very very short. The ones with red center are not more then 50...

Hi Jochen,

Well done and I have not seen the Sun for the last 10 days or at least had a hole big enough to record my videos.

Re: Perseid Meteor Detection by Radio

Hi Stu, It is me again :roll: . Well I did run two days for 9 hours the SDR and recorded a video with audio. After analizing the both videos I get very short ping but not with a very high pitch but a lower pitch which seems to be 1 kHz. I am pointing at a transmitter 1225 km away which is possibly t...

Re: Perseid Meteor Detection by Radio

Hi Rainer, Spectrum Lab simply measures, displays and records audio frequencies, so nothing to do with the radio frequency. The vfo setting is not important. It is not used in this part of Spectrum Lab. The audio tone (frequency) generated by a meteor results from the difference between the SDR tun...

Re: Perseid Meteor Detection by Radio

:Hi Stu, With the help of Bob Alongi from Scottsdale, Arizona, USA I am slowly understanding all this a bit better after doing some tests on nearby TV stations and focusing on the ATSC pilot carrier frequency which is the lowest MHZ vale of each channel + 310 kHz. What is still a bit unclear is the ...

Re: Perseid Meteor Detection by Radio

Hi Rainer, Looking good. To your questions: fc is the central frequency on the Spectrum Lab frequency scale and sp is the span above and below the central frequency. In this case 2kHz is the central frequency and the span is 2kHz below to 2kHz above. vfo is the radio frequency. If the frequency is ...

Re: Perseid Meteor Detection by Radio

Hi Stu, The 4 element Yagi antenna is now connected to the dongle and the operator is scanning the SNOTEL 40.67 MHz frequency. Antenna should be pointing at 4° but I guess that does not matter in this case. Question here is teh strength of the reflected signal from the meteors. One more thing I am n...
