Was channel surfing around Ridgefield heading North on I-5 and hit 98.3. I Like the music from what I heard and it was clear in that area. The sports break actually had local High School events mentioned and the news break talked about local events and happenings.

I will check tomorrow when I am back in town but does anyone in PDX pickup this station?

"The Peak 98.3 is a music intensive format. With fewer commercial interruptions than traditional radio programming, the Peak has a maximum of three breaks per hour, totaling just 10 minutes of commercial time." Gotta love that!

I can hear it ok from Hillsboro with an outside FM antenna pointed north, and good quality tuner. Decent enough signal for stereo much of the time. So, with a little effort...yes. With a whip antenna on a portable...no.
Should be a little stronger on the other side of the west hills, however.

It's receivable in Southeast Portland with a decent home or car tuner and antenna.
It takes roughly the same amount of effort as it does to pull in 105.5 from Longview.

It seems to pop right in on I-205!

It was fine all the way to main street then broke up till I got to the I-5 bridge where it cleared up till lombard then broke up again. But while I had it I liked the music they played a lot.

Are there any good replacement dipoles that would give me better reception and/or antenna amplifiers? Any advice/suggestions. My current metal stick is one of those kind that looks like a spiral wire is wrapped around it. GM stock antenna.

Just a guess here, but it is likely that as you got past Lombard your car radio was overloaded by the strong local signals from the west hills... no better auto antenna or amplifier will help in this situation, and will usually make matters worse. There are reports of reception in the area, posted above, but all of these are some distance from the Portland "core area", where the local signals are weaker. I suspect that reception of this station while driving around town will be spotty at best.
On the other hand, a good directional FM Yagi in a fixed location at your home, coupled to a decent tuner could produce satisfactory reception.

Thanks. I was just looking for an alternate to Mark & Brian on the morning drive and cant quite settle in with Charlie either. Guess I will just settle with what I can get. They have a pretty descent playlist from what I have heard so far.

Add:
Do you think that once we cloud up the signal coverage will lessen/strengthen? Can atmospherics affect radio reception?

In winter, I have noticed that a good heavy ground fog quite often enhances strength of medium distance FM signals... Anybody else notice this?

Fog generally is considered to absorb RF, although inversions are tricky to analyze/understand.

There is a ton of info to wade through. Here's a good start

Some good stuff there!
