Hi Roger, unfortunately I can't receive WWV here in Europe. But I can receive a Russian time signal on 9.996 MHz.?
My Frog has a Kokusai filter. So I had to reallign the BFO. In USB position, zero beat is not the same as the carrier frequency. I have checked it also on broadcast stations. It is always 1,5 kHz above the frequency.?
Does your Frog has zero beat on the carrier??
When the signal is exactly in the middle of the filter,? the frequency on the display is spot on. So the counter calibration seems to be okay.?
