Hello Ken,

Well, it is difficult to comment this if i have no impression of the wideband view between the different antennas. The filter is a 3 stage LPF, cut off at about 13 kHz. Generally the probe works well so it may be a problem of grounding or something elso is wrong. What is your RX, i simple soundcard?
Could be interesting to compare different wideband screens!

I saw a very faint trace about 10.00UTC using my 'T' antenna at a height of 8M, but nothing on the E-Probe at 5M on a non-metalic pole, the distance between Chris and myself is about 15-18km, I would be grateful for your comments Stefan. Also what are the charicteristics of the filter between the two FETs?
