8.27 KHz across the ocean.

Just saw a notice from RSGB that VO1NA was received by DK7FC on 8.271 KHz with a 50 character EbNaut message, running 10 mW ERP. No date given.

 

That IS highly impressive

 

He must have yelled REALLLLLLY loud! /s

That's cool, and a LONG-arse wavelength! -- ~22.5 miles for yanks, 36.25Km.

 

The ERP was 10 µW, i.e., microwatts, not mW milliwatts.

Distance was about 3500 km so the whole path was about 96 wavelengths. It sounds like the transmission took seven hours.

If only my audio input cable was not shielded -- I could have picked up that tx !!

 

Impressive!
Makes me think if it may be an idea to ask the authorities if the amateurs could share 17,1-17,3khz with SAQ Grimeton on the days they don't transmit. Apart from SAQ, i've never heard anything on that frequency.
