*/However I do not have any powerful transmitters in the neighbourhood ./* I do, and that simple circuit generates many 2nd-order intermod products from the local MW AM stations. The loudest signal a
To all , I,m using an active antenna simular to Roelofs mini whip for over 10 years ( circuit practically the same with DC coupling between the J310 and the 2N5109 ) with very good results . I tried
Scott..I have had similiar results as mentioned by KC3OL.. My miniwhip has performed very good even as good as my LF loop that I used for a couple of years.. I have not noted any intermod problems an
Could you have a faulty device? I have a mini-whip made by the man himself and it performs very well Tracey Mike Everything is exactly as Roelof published the specs and dimensions... I hear WWVB and
Mike Everything is exactly as Roelof published the specs and dimensions... I hear WWVB and Dixon, BUT it is nowhere near the levels I get on any other antenna for this region of the band. Lots of int
Scott, we tried a miniwhip at Quartz Hill last trip at about the same height as you have yours and it seemed to work well. JJY on 40kHz was strong and DCF77 was audible. Coupling capacitors the right
Hi Scott, My mini-whip works very well down to 10KHz & has been mounted at about 15 feet on a fibre-glass fishing pole. I can usually hear the Alpha transmissions around 10/12KHz. It does not out-per
