Thanks Jorge. The others are lower power and farther away.

Recorded at the wild Rockwork ocean cliff near Manzanita, Oregon USA yesterday morning (August 6th) at 1300 UTC, at least one strong Australian station on 531 kHz is in the following clip, with apparent ID's at 10 seconds ("Radio _____") and at 3:22. There apparently is another Australian station mixing in at times, and possibly the Kiwi station PI in an island language. Any suggestions or comments about the identity of these stations would be appreciated-- thanks!

The really astronomical indexes come from low-powered Longwave aeronautical beacons (NDB's) received at ranges over 10,000 km across the equator. 362-WK in Whakatane, New Zealand (25 watts at 11,017 km from Manzanita, Oregon) results in a wacky index of 440.68, while 366-SF in Springfield, New Zealand (50 watts at 10,977 km from Manzanita, Oregon) results in a more modest 219.54.

The best medium wave DX index at the same Rockwork Cliff would be for reception of 558-7BU in Burnie, Tasmania, Australia during the August 2017 DXpedition. That 2,000 watt station was received at 13,128 km from Manzanita, for a very modest index of 6.56.

I have had for many years used a combination of distance and power making a 'points' system. It does not take into account the subjective nature of poor, weak, average, good, or excellant. Sometimes receivong anything readable is good. And sometimes a high-power station might be received poorly/weakly, or just average. So here's the formula...

(Log(500,000)/Log(Power)) squared times the distance (km)

As option take the square root of the values and multiply by the points answer above...

poor = 1 (1.000), weak = 2 (1.414), average = 3 (1.732), good = 4 (2.000), and excellant = 5 (2.236).

Just a suggestion to try out. I think you will find that low power aand high distance to be 'real DX'.

Then I concur, the PL-380 is a solid choice. To use the AN-200 antenna, off-set the PL-380 tuning by 1kHz to greatly reduce or eliminate the Soft-Mute effect.

Thanks for your assistance, Paul.

639-2HC and 639-5CK have both been heard at this cliff previously, and I'll probably need to check the ABC website (with the program podcasts for the LR and RN networks) to narrow this down further. Or, if that's a dead end, just ask my SDR-DXing partner Tom Rothlisberger for RN network, LR network and SRN network parallel checks.
