Opera on 6

I haven’t used the Opera digital mode on HF for a bit as it seemed that interest had dropped off and there is not much point in beaconing in no-one is receiving. It seems to be one of those modes where there is a resurgence of interest whenever there is something new to try. This weekend the new thing was some fast Opera modes for use on VHF so I fired up the K3 on 6m (50.700MHz) to see if I could receive anything.

As you can see, not only did I receive some other stations but my own Opera signals were received around the UK. No great DX, but I was only using 20W to my attic dipole and would not expect to hear anything on 6m at this time.

If enough people were prepared to use it, this could be a good tool for discovering Sporadic-E openings on the VHF bands. The 30 second transmit cycle seems more appropriate for this type of propagation than WSPR’s two minute periods.
