Simple QRP projects, 10m, 8m, 6m, 4m, FT8, 160m, WSPR, LF/MF, sub-9kHz, nanowaves and other random stuff, some not related to amateur radio.
It is a dead certainty that I have never even come close to winning the AL section of this contest! Why? 10W to a 2m big-wheel omni antenna ...

Hi Roger:
I was reading the specs for the BAZ Spezialantennen LF/VLF ferrite antennas and it mentions that they can be used on transmit for “small power levels.” Unfortunately it doesn’t say how small! I know you experimented with ferrite antennas before, so do you have any thoughts regarding using such an approach at 475kHz for WSPR applications?
Regards,

Keith - I am not familiar with this antenna, but it should work as long as the ferrite does not saturate. It is going to be some way down on a "real" antenna.
Agreed! I would wonder how it would compare with earth probe antennas; also it would provide the novel concept of a rotatable 630m antenna.....😄
