Singling out 2 stations on same frequency

Post by Kona » Wed Nov 22, 2017 5:49 pm

Hello there. I have a question to pick your brains with. I live here in Baltimore, Maryland but I occasionally travel back and forth to Norfolk, Va. There is a station down there that plays classic rock, it's frequency is 106.9. So i'm driving down the road here in Maryland and I turn on 106.9 just for the fun of it and I'm able to receive that station from Norfolk waaay up here (about 250~ miles) but it seems like it's fighting with another station on the same frequency that's based out of western MD. Each station is received for a couple seconds and they become clear half-way through before the other is received and it just goes back and forth. One day, the station in western MD went down for a couple hours and I was able to receive the Norfolk station clear as day, even with all of the radio data and HD signal. I believe the reason for being able to receive the signal from so far away is because the station is beaming it straight up the chesapeake bay with no obstructions. I am also able to duplicate this on the radio in my garage.

Is there any possible way to single out one of these stations so the radio doesn't keep flip-flopping? Like some sort of fine-tuner? I understand there are other classic rock stations around and there's the internet and everything, but there is a cool factor to listening to a station really far away with A basic FM radio.

Thanks for reading!

You can do it but it will require a rather large directional receive antenna mounted on the roof, which won't do much for your car's aerodynamics.

Ah, I understand. I'm actually looking for something more along the lines to work in my garage. I'm borderline entry level to this, is there any antenna you'd recommend?

Thanks

Try one of the many cheap antennas on Amazon for around $25-$39/ I've used them in a couple of situations where it's not possible to use anything large. They include a pretty decent amplifier intended for UHF/VHF but which seems to do quite well with FM. Rotor is built in so you can point it at the station you prefer and leave it there but can also scan around just for grins and giggles. They're not real durable in winds above about 40 MPH and not worth fixing if one gets broken so, given the price, I just keep a spare around. They have several brands, most have a gray plastic wedge-shaped central section that houses the amp and rotor mechanism.

My guess is that if you can receive that fringe a signal at all someone will be putting a translator on that frequency in your local area before long. From my experience those cheap antenna are a "you get what you pay for" JUNK! The built in amplifiers are noisy and very easy to strong signal overload. You would probably be better off with one of 4 element FM yagis that show up on ebay and other places online. I think Channel Master and Winegard have discontinued they large yagis for FM. There are some large specialty FM antennas out here but be ready to open you wallet.

Assuming one is available, can you stream the station?

While I agree that cheap antennas are far from perfect they are a good way to see what you can get for reception without going broke. I've bought big-name antennas at big bucks only to find there really was no point. If a cheapie gets results than it's easy enough to spend $400+ for something really durable but, unless you have money to waste, no point in experimenting with the spendy good stuff. In one instance I replaced a cheapie that proved the point with a frequency-specific professional antenna and, since the installation was meant to last 50 years, it was money well spent. But not for something that's a passing fancy.

This will probably be a moot point for the OP. I see there is a CP for a 110 watt translator in Baltimore on 106.9, so that will probably wipe out any DX on that frequency locally when it comes online. DX ing on FM broadcast is becoming a thing of past with all the translators going on the air. More coming as the Auction 99 batch get granted and the Auction 100 opens in January for yet more.
