Converts specific Aurora Activity (from 1-10++) to the calculated K-Index (from 0-9), and to the lowest Latitude (North or South Hemisphere) range in Ks that you can expect Auroral activity (either visual or radio frequency) You can also enter a specific calculated K-Index (from 0-9...
Always start out with an antenna that is too long,i.e. resonant below the desired resonant frequency. Cutting wire is easier/cheaper than adding! Dimensions arefor each leg of a half wave dipole. For quarter wave antennas: apply the change in length directly from this chart. ...
Chart 1 shows that the noise levels measured on 15 August are approximately 10 dB greater than those measured on 10 May. It seems likely that this shift is mainly due to the greater number of 3 The club conducted some HF radio frequency noise measurements at the Meridian Energy Te Apiti ...
Over on YouTube Sarah is back this week with a new video on her channel SignalsEverywhere. In this video she shows how to decode HF WEFAX (weather fax) images using an Airspy HF+ Discovery software defined radio with a YouLoop antenna. HF weather faxes are daily weather chart images trans...
