Here are some photos from Stevenage and District ARS weekly 2m FM club net as G3SAD/P over the last four weeks. Members meet at 7:30pm with due regard for social distance and have enjoyed seeing and hearing everyone #GOTA2C. All welcome whether licensed or just interested/curious.
UPDATE: As groups of more than 6 are now illegal, we will meet on the air on Tuesdays 145.45 FM from 7pm approx. G3SAD will be in use.
Dont forget that the club constuction competiton will be on March 3.

Bryan Harber presented a review and hands-on demonstration of the nature and mechanics of Frequency Modulation. Beginning with a demonstration using a signal generator and oscilloscope he visually demonstrated how AM “works” and then explained why FM cant be demonstrated visually the same way. Instead a spectrum analyser was used to do this. Discussion on multiple sidebands, bandwith and “channels”, “capture” and other licence-relevant matters followed. Powerpoint slides
