Thanks Claudio.I just installed a newer power supply for the probe, which runs at 15V instead of 12V. This should rise the clipping points a bit. Samlls steps... There are some occasional QRM traces on the grabber in the afternoon but the main IM and probe problem is solved now. Am 11.10.2012 19:07, schrieb Claudio Pozzi: [...] p.s. See also the M0BMU preamplifier schematic output transistor in "Bandpass Receiving Loop Antennas". Yes i know it off by heart :-) 73, Stefan/DK7FC |
