My limit of time is QRS 60 and preferably Faster. We need the transmitting stations to increase power ie more ERP then there would be no need for uH bandwidths and year long dashes hi de mal/g3kev ----- Original Message ----- From: "Markus Vester" To: Sent: Friday, March 11, 2011 9:30 PM Subject: Re: LF: VLF traces > Dear Mal, > > with all due respect, I very much disagree here. > > Whenever I see a clear trace appear at the right time and within a milliHz > of a confirmed and correctly calibrated frequency, I have hardly a doubt > about the validity of the reception.
