B079CNCR8V Price: $19.95 Score: 1000.000 Category: Electronics Rating: 4.2 Votes: 178 Find similar products Flamingo FM - Broadcast FM Bandstop Filter (FM Notch Filter) for Software Defined Radio (SDR) Applications. A high-quality, high-performance bandstop filter designed for software defined radio (SDR) applications. Designed and manufactured by Nooelec in North America, with a full 2-year product warranty. Broadcast FM can be particularly problematic due to the high-powered transmitters used for broadcasting in some areas. These signals can overload the front end of an SDR, causing imaging and a number of other issues. We designed Flamingo FM to provide sufficient attenuation for broadcast FM frequencies (>40dB typical) while ensuring adjacent bands, such as the important VHF airband (108-137MHz) are minimally affected. The -3dB rolloff of the filter is 80MHz and 115MHz. Minimal out-of-band insertion loss means the filter can stay in place for most any application. As a true bandstop filter, you are able to pass-through DC (bias power) when it is required. DC current handling is 250mA (min), and the maximum recommended signal level is 18dBm (5Vp-p), so there is no issue using the filter for higher-power applications. Typical performance characteristics can be found on the downloads tab of the product page on our website. Flamingo FM has its filter circuitry fully shielded with an EMI frame, and has its front end protected by an ESD diode meant for RF applications. 2 mounting holes are available on the PCB for various mounting options, and the SMA hardware (washer and nut) is included.	B00FNITQRW Price: $264.99 Score: 5.587 Category: Electronics Rating: 4.3 Votes: 24 Find similar products MFJ MFJ-1026 Noise canceller, 1.5-30MHz. MFJ Noise Canceling Signal Enhancers are designed to reduce noise or interference, or improve desired signals, before the noise affects sensitive receiver circuits. Unlike conventional noise blankers, these units can be effective on all types of noise (QRN), as well as on interference (QRM) from unwanted signals. From the Broadcast Band to low VHF, these Noise Canceling Signal Enhancers work on all signal modes and can transform difficult receiving situations so you can finally hear, work, and log that rare DX! MFJ Noise Canceling Signal Enhancers allow the user to adjust both phase and amplitude while combining antenna inputs. One of two antenna inputs may be connected to the transmit antenna, and the other to an external receive antenna or the internal whip antenna on the model MFJ-1026. Or both inputs may be used with identical receive antennas to create various directional patterns for optimum results. The signal output to the receiver or transceiver is the vector addition or subtraction of signals from two separate antennas, balanced and phased. This allows unwanted noise to be removed or desired signals to be enhanced. Some other phasing systems provide either a limited phase adjustment range or change the signal's level as phase is adjusted. These MFJ units feature exceptional phase amplitude flatness making adjustments easy. Null out interfering signals or peak desired signals with the adjustment of a few controls, and pull in that station you want to hear! MFJ Noise Canceling Signal Enhancers are optimized over the range of 1.8 to 30 MHz and contain the interface circuitry necessary for operation with most modern HF transceivers. Although these signal enhancers contain internal RF sensing for T/R (transmit-receive) switching, we strongly recommend the use of the external T/R control connector on the rear panel for keying. These units run on 12 Vdc or 110 Vac with an optional adapter, sold separately.

Specifications: Output Power: 100mW Modulation Mode: standard FM Equivalent Noise: >=30dB Power Supply Voltage: DC 3.0V-5.0V Operating Current: 35mA Adaptive Antenna: 75cm bar antenna Audio Frequency Response Range: 50Hz-18 KHz Transmission Frequency: 76.0MHz to 108.0MHz (Campus broadcast: 76.0MHz-87.0MHz) Frequency Adjustment Stepping: 0.1MHz/times (short press the key); 1.0MHz/times (long press the key) Sound Track: LINE/USB channel (stereo); MIC channel (single channel) Settings: 1. Setting of backlight LED mode When the power is off, press the “FRE-” and “FRE+” button at the same time to start up. B1 indicates always bright. B0 indicates that the backlight is closed for 20 seconds, and the reset setting takes effect. (the factory defaults to 20 seconds of backlight delay). 2. Start/close the campus radio frequency band Press VOL+ and VOL- key at the same time, and then connect the power supply. LCD displays C1, which means to start the campus broadcast(76-87mhz). C0 means closing the campus radio frequency band. Take effect after restart. (the factory defaults to close the campus radio frequency band). 3. Settings of stereo/mono transmission mode The back of the module has two solder joints M,G. Short connecting is the monophonic launch. Disconnecting these two points is the stereo system launch. (the factory defaults to stereo system launch). Note: the stereo system must satisfy the input to the module's audio source is stereo and the radio is also stereo to achieve the stereo effect. When using a single speaker (monophonic) radio or input to the module's audio signal as mono, there is no stereo. Package Includes: 1 * Digital FM Transmitter Module.

B003H2HWOK Availability: Currently unavailable Score: 5.291 Category: Electronics Rating: 5 Votes: 1 Find similar products CA8800 FM Band Separator Coupler FM Tap TV-FM. The CA-8800 is used to split off the frequencies for the FM band. This is a great way to utilize your TV antenna to pull in long distance FM signals. Even when running a VHF antenna straight to an FM receiver you can get all sorts of audio distortion. With an insertion loss of -0.4 dB, this unit is far more efficient than using standard splitters, that have an average of -4 dB. The Winegard CA-8800 only passes the FM band to get clear crisp audio. Couples or separates VHF/UHF/TV and FM signals on 75 Ohm coaxial lines.
