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. Even more so if the transmission can be verified by comparison to a calibrated grabber in another location. It seems that the G3KEV antenna does have excellent sensitivity at VLF. It would be fantastic if you could augment that with a stable, properly calibrated, and narrowband reception system. SpecLab has made that so easy now - throw out the wildly drifting "receiver", connect your antenna directly to the soundcard instead, lock to one of your MSK neighbours (GBZ or GQD), and your in the game.

Frequency alone is not a VALID report- it could be anything. G3KEV
