I expect that historical societies would have more membership and more participation, and perhaps even more financial donations, if members could participate in active two-way use of the stations and QSO's with us.
The UK 500kHz Experiment
Even with perfect impedance- and resonance tuning for the operating frequency , the SWR indicated by the transceiver itself never dropped below "2. From Wikipedia, the free encyclopedia. Part 15 rules, page 80 is the list of frequencies where intended radio emissions transmissions is not permitted. On this occasion, a big thank you to everyone involved! That's why I like to build my own receivers, both solid state and tube.

I would be most interested to know where, exactly, kHz is still used for distress and safety communications I feel the ITU would most likely take a more serious look and approve this proposal if the amateur radio community were to express their involvement. Two new towers for transmitter site
There is nothing that exists to do that, so this is where the term "velocity" comes in. MF Maritime radio frequencies. Medium Frequency Marine Radio stations in Japan.
