Re: LZ1AQ: iMDs from local AM stations in Dipole mode

20m and 10m look clean on Spectrum/Waterfall but SNR is very bad, sensitivity is low. Antenna seems to be just dead.

I meant to write "deaf", not "dead", sorry. I still see some strong signals which go away completely when I shut down the power supply, so it works in Dipole mode on 20m and 10m, just not as sensitive as in Loop mode and any other antenna I have. Which can be explained if HighZ amp is IN or close to be in saturation. And this is an opposite I hear from other people who use this amp on higher bands. If I'm not mistaken some people were having a better sensitivity and SNR in Dipole mode on Higher bands compared to the Loop mode. I was actually hopping for that.

Simon
