MF
Now that MF is shaping up with DL permits and others.
If you can find a DECCA sub unit 5501 it takes less than a couple of hours to
modify/ adapt for the 472 Khz band. In round figure values all that is needed is
a 22uH in series with 5 nF C. Adjust L for frequency of interest of
centre of band. A matching transformer is then required to match approx
5 Ohms to 50 Ohms and LPF to the antenna.
I use an old tube TV LOPT and it works well with
good efficiency.
A couple of hours work and you can be on the new 473 band.
A loaded inv L antenna and you are in business.
