5 MHZ IMPROVEMENTS

UK operators holding a 5MHz NoV may like to note that after dark
propagation on the East-West path to the USA peaks when America also
falls into darkness. To check the condition of the path, European hams
should listen out for AM broadcasting stations WWCR in Nashville on
5,070kHz and WWRB
on 5,050kHz which is also in Tennessee. Both employ 100kW.

American operators can check the path in the opposite direction by
listening for the USB AIRMET stations RAF VOLMET on 5,450kHz and
Shannon VOLMET on 5,505kHz.

UK operators should find US amateurs congregating on 5,403.5kHz around
01.00 to 02.00 GMT.

The path to the Far East can be checked by listening out, after sunset,
for the Chinese Standard Frequency station BPM. It identifies at
regular intervals in Morse code on 5,000kHz.  The chance of a contact
on 5MHz in this direction is remote, but one or two American radio
amateurs are believed to have authorization to operate from military
bases in the Pacific.
