I love the KUSC classical station which is broadcast out of LA. My folks love it too when they come to visit but they live in the far north of the state. KUSC is rebroadcast out of Sunnyvale, CA at 6000 watts but they still live about 350 miles north of there. I'd love to be able to set them up with a system that will pull it in over the air. KUSC is broadcast over the internet too but it wouldn't be the same.
Definitely looking for both the ability to pull in the distant station and for audiophile sound. They do live on a hill but they don't want an outdoor antenna. Can we pull this off? Any suggestions for either a tuner or receiver? They'd be starting from zero and would need an amp anyway.

Listen to Timbo. He is our resident voice of RF sanity. I've been an RF engineer for my 32 year Career, have designed antenae as well. I hate the term "pull in", antennae are passive devices, like a lens. Lens don't image things they are not pointed at. They do best when the subject is "on-axis", that is they are 'directive', as are antenna designed for DXing. That 'whip' on your car (if old enough) is cylindrical and so responds as well in all directions in a circle around it's axis. It's omnidirectional. A directional antenna is like a ;figure' bra, it takes what you have and squeezes it it in the desired direction.
I used to listen to KUSC as well, while at UCLA. Depending on where your folks are relative to the Coastal Range you may be able to get some signal from Sunnyvale as the Bay and corridor point north are relatively flat. 350 miles is a challenge, though. I'd set them up with internet streaming, if available.

FM radio reception as a dependent system, depending most on the antenna, and accepting that as FM wave-lengths are 12 ft on average that the antenna thus CAN'T be small.
Gain is the issue and gain is orthogonal with size.
Especially when DX-ing which is the case here.
The internet has lots of FM Dxing sites, to boot.
That they live on a mountain won't hurt, but the facts are what they are.
------------------------------------------------
This attitude which focusses on the tuner / receiver seems rife here, and is implicit in your originating post.
It is simply not possible to get an FM station > 200 miles away without a seriously large antenna aimed at the transmitter.
A large exterior Rhombic -see FAQs here - on poles would be cheaper that two big and long and stacked log-periodic boom antennas.

Much closer stations on same frequency and probably in the same direction. I didn't see where he said where they were or that they were on a mountain.The station has a good Internet feed and interestingly a nice three page PDF download on FM reception on their site.

But, my case rests about people who seem unaware of the importance of antennas for FM, while obsessing about the tuner.
It's like buying a Koetsu cartridge and putting it on a Garrard Sp25.

Yes we see that all the time. Very few people seem willing to put up any outdoor antenna anymore much less a good one.
I did think it was cool they had a well written PDF on FM reception on their website.

Probably just a wild guess but is the station available on the internet?
Link below. I listened, its an above average stereo stream.

You cannot.No how no way. Besides the distance and geography/topography there are other stations on 91.5 much closer to them. You didn't say where they are but 350 miles north of LA there are other stations on 91.5 like in Fresno that would block it even if you did have a high outdoor antenna, rotor, great gear, totally flat land and no other station on that frequency. You have none of those things. The Internet is your only option.

I would echo Timbo-
and add another option/suggestion1: make a full size Rhombic - per Tim's link.
then AIM it torwards the transmitting tower- use FM FOOL.com for the polars2: select a great tuner-
everyone has their favorites -
Tube front end/ tube unit
Solid State-I have used a few and have some preferences -
I would spend some time on the Tuner Info site -If they are in Nor Cal- There is a Kenwood Trio that has been for sale out of Berkeley for a while now-on CL. The guy wants $1100 - which could be the right price - but I can't swing it - NO Affiliation...
McIntosh made some great tuners - including the MR-74 / 73 / 77 for Solid state and 67 / 71 for tube
Accuphase
Tube Tuners are becoming more like mid 70s Jaguars with the maintenance and parts issues ...
It can be done - but the antenna is KEY!
Happy Listening

At that range outdoors is best, as the sides can be even longer.
UV stable 300 OHM ribbon would double the gain for s given size.

Outdoor antennae, tell your folk to move to Mount Whitney with an elevation of 14,000 ASL they should be able to pull any FM stations at more than 1000 miles away.
If a thing's worth doing, it's worth doing well
(Proverb)
Height is important but still no chance with a closer station on the same frequency as in this case.
I did talk from Mt Mitchell, NC to Arizona on FM with 100 watts but that's because I was on 29 MhZ. My all time FM was on the same band from WV to the Czech Republic.

all bets are off. Even with one, given the 350-mile distance, your parents would be hard pressed to get even close unless they were blessed with favorable skip-distance propagation, whether their location is Crescent City, Yreka, or Hilt. And they have not-insignificant intervening hills and mountains to deal with.
When I lived atop a hill in Pacifica, CA, decades ago, I managed to get a listenable, fully-separated stereo signal from Fresno, about 160 air miles away. The tuner was a McIntosh MR-67 fed by a Finco FM-5 yagi antenna mated to an absolutely essential rotor and mounted about 10 feet above the roof line. I considered myself lucky.
I know tuner technology has progressed since then, but you still need an outdoor antenna (preferably one you can position with a rotor) to even approach what you're suggesting.
Good luck.

Good info, thanks guys. I'll start them on their local classical station with ads and if they're hungry for more we'll experiment with outdoor antennas.
Don't bother with outdoor antennas for KUSC never gonna happen. Outdoor antennas will be great though and perhaps there is something closer to them with classical that is good.
