📻 FM Bandstop Filter v2 (FM Notch Filter) - Flamingo+ FM - Enhancing Software Defined Radio (RTL-SDR) Applications by Blocking Interfering 88-108MHz Frequencies from SMA-Connected Radios Review

This is a much better filter than the original model for most applications requiring an FM tag. His shoulders are much sharper and so you can use the planes band, which is almost useless with the V1 filter. (See my sweeps above for both filters. The V2 filter is much sharper of the two.) Attached, this is just a reference image of what you will receive to show its overall size compared to the N-SMA adapter and load . This gives you an idea of how small it really is. These things are about the…

This well made FM bandpass filter solved my problem when Radio Amor 100.3 FM was overloading my SDR transceiver. 100.3 FM with 14.5 kW for 10 miles distance was blocked filter. Success! The filter is labeled input and output side, which means you must use it with an antenna connected to the input. I tested the filter and as you can see from the pictures the filter is non-directional and you can use it in any orientation. Since the filter is bi-directional I use it in a QRP transceiver and have…

I have Received this because I saw a lot of harmonic interference from VHF radio when scanning with my SDR. I scanned and saw a strange signal at high frequencies so tuned in and. Hey, that's the harmonica from one of the big radio stations. I'm pretty far from towers so I didn't really think I'd need it, but apparently I do. The overtones are definitely reduced and the original frequencies are still somewhat in tune, although I don't normally use my SDR. to listen to FM radio. I was able to…
