I can hear a very faint signal on 1660 from Hillsboro. It appears that they are broadcasting parking information, but I cannot be certain what is being said. In fact, the signal is so faint that I couldn’t tell that there was anything on 1660 before I unplugged my laptop AC adapter–and this is using an outdoor loop antenna.
If you hadn’t told me about the Washington park station and I had found the signal by some happy coincidence, I would have thought that I was hearing some sporadic daytime skip, as I occasionally do on some other expanded band frequencies.
Yes, I have 1500′ running at about 75 degrees to the East. But the past few months I have been dealing with a lot of noise, but the Eastern Beverage nulls most of it.
I use a Drake R8 receiver. The antenna is read with Rg6 to a homebrew matching transformer. It works pretty well. I have had the antenna since the early 80s, but have replaced the wire.
