); SAEximRunCond expanded to false Errors-To: [EMAIL PROTECTED] RETRY OK, thanks for the useful information . I thought you might have resonated the loop to get some filtering ahead of the preamp, which is what I would have done, not knowing any better...
If I use a ferrite rod, it will most likely have too much stray capacitance to be broad band, but the air loop as you have done is not too big, so I may try both. Looking at the spectrum analyzer plots, it seems I do not have too many competing signals around here, so on the one hand, a broad band loop should work nicely, on the other hand, there is no other signal around I am interested in, so I may tune the loop and get some filtering.
