Hi Alan, I did not check the equipment calibration either, next time I will (I expect the frequency to be within +/- 10 pow -7) And I'll care also of the Loran lines when "choosing" a transmit freque
Hi Michael apologies my frequency calibration was out on 3 sec dots mode. I make your DFCW dot 137.690 at 22.28 and nicely clear of any strong Rugby Loran lines. Fully "O" copy of course Cheers de Al
Michael I make your frequency 137.718 ( I have not checked my calibtaion recently so I could be wrong) at about 2115 but you are almost right on top of a Rugby Loran line Alan G3NYK
