Now up to the top of the X-band:

Brian, I'm very glad that you're on board with the Victoria DX team. Several factors to consider:
1/ Location is everything. I'm only a couple blocks from the ocean. This makes a huge difference. You can test this yourself. I've done it on a number of occasions. I chose Cook Street driving down towards the waterfront. Tune into 1610....there's a very weak TIS from Port Angeles (it's harder to hear now with the Hindi 1600 station, though). As you drive down Cook St, one will see a big rise in signal strength from the flea powered station across the Strait. This is the ocean enhancement that is very well known. There's a huge difference even a few miles inland. That's why so many (most) DX sites around the world are on the ocean!
2/ Antenna: I have some pretty big large diameter corner fed (see Bruce Conti's website for more details) loops. My best DU one is a good 50 to 60' high and some 75' or so horizontal...lots of gain from that puppy. The W array is only a little smaller. In most circumstances, it far surpasses the ALA 100, and even that one, as good as it is, still has a diameter around 40 or more feet.
3/ Just keep on trying. For several years now, I've started in mid to late August and listened almost every morning from about 30 minutes before sunrise to a few minutes past. It pays off as you get to know the frequencies. Keep the PAL list handy as it's invaluable to look up who the stations may be.
....Walt.
