Heard it on the 'X'
The new Mexican station on 1700 doesn't seem to be a problem here in the Puget Sound area during the daytime. At night, though, it comes in like a local and reduces my signal to 1/4 mile radius. Supposedly, this station is either a daytimer (not) or at 1 kw nights (I don't think so).
For now, I plan to continue operating on 1700, although I might start signing the station off at 10:00 pm. It's hard to find an open frequency up here. There are over 30 AM signals in the market.

I checked the FCC database on this station, and it's 10 kw directional at night with a null to the east to protect a station in Texas. There's a TIS on 1700 at Lake Quinault in Washington State, and I'm sure it's useless at night.
there seem to be 2 stations on this freq. Theres the one that I've got access to recordings of claiming to be "XTRA" - although theres a guy in san diego who swears this is impossible. Ok.. whatever..
There's also another one that is kill me at about 7PM - Radio Romantica Columbia (althoug I highly doubt they are actually IN columbia).. this is likely in FL and probably not legal. These guys come in like you're playing a cd.. it's incredible really.. I think they get filtered out at the altamont.. this must be a corridor thing.. I dunno.. I'm not an engineer or physics phd - but i know what i hear 🙂
I'm moving to 1680.
I'm going to have sign off early and listen. I picked my daughter up from work yesterday about 8:15 and my station had its normal coverage. By 8:20 pm, the interference was getting really bad. When I first discovered the problem, I could barely carry the signal a quarter mile!
yeah.. theres a thread on this ... another one that kind of pushed me off the crusa forums..
I had someone do an analysis on this.. and it's 2 stations.. I orginally thought it was XTRA doing the night time stuff.. but mr engineer did some funky airwave grabbing with some oscilloscope looking doohickey and collected audio data over night. turns out there 2 .. weird.
I think that me staying on 1700 is going to be impossible.. and in the winter it will be just plain evil. 1680 is clear for me.. so is 1610 - but I'm not moving in on that 🙂 My town (or one nearby) may decide to setup TIS)
There's certainly one operating a very high power, as they're booming in here!
I'm sort of stuck although I might look at 1500. I'm also looking at 1270, but I need more information on how to get any sort of coverage that low.
my understanding (and I make people explain this to me like I'm a CS Engineer - not a physics one 😉 ) - is that the better the grounding the better the coverage area, and that the higher the freq, the more effective the tiny antenna we get is.
You might go through the list of stations by freq and ask a couple of the guys running at lower freqs how they are getting along.. 🙂
