Sub-9kHz NoV - still awaiting Met Office OK

I chased Rod at OFCOM this weekend to see if there was any further news on the NoV application to TX below 9kHz. The hold-up is still the Met Office, from whom OFCOM are awaiting approval. I'm carrying on with sub-9kHz earth-mode and induction tests at 4W meanwhile as I can't imagine anyone will object. My transmissions last about 10 minutes and the radiated power is picowatts!
