## Overview

The Distill:AM Barebones is a high-performance broadcast AM bandstop filter designed specifically for software defined radio applications. It features a sharp notch filter attenuating AM signals by up to 40dB between 350kHz and 1900kHz, while passing DC bias power up to 250mA. Its fully shielded EMI frame and RF-grade ESD diode protect sensitive front-end components, ensuring clean, interference-free reception. Compatible with popular SDR devices like Ham It Up upconverters and RTL-SDRs using direct sampling, this US-made filter comes with a 2-year warranty, making it an essential upgrade for SDR enthusiasts seeking superior HF performance.

Review: Works very well. - I recently purchased a KiwiSDR. Though I do not live in a large city, there are 3 different 5000 watt AM broadcast towers within 4 miles of my location, and a 1000 watt tower less than 1 mile east. This was causing constant ADC overloading in the Kiwi, with spurious signals across the whole range of the receiver. The filter definitely works well. All of the local stations are attenuated by at least 18 to 20 DB, and the spurious signals in the waterfall are gone. It appears to have no attenuation on a local LF NDB on 245 KHz, nor on CHU at 3.330 MHz, so the bandstop limits appear to be as advertised. It has definitely improved the performance of the Kiwi on HF. Another reviewer remarked that the antenna should be connected to the SMA jack marked “output” and the receiver connected to “input”. I tried it both ways, and it seemed to work exactly the same in either configuration. My only concern is the way it was packaged for shipment. The filter is in a small plastic bag, which placed in a non-padded envelope. It arrived with no damage, but packaging it that way could easily result in the unit getting crushed in transit. I would recommend that the item be shipped in a small box.
Review: Works as expected - The filter works as expected as far as I can tell. I've added a few photos of the filters performance as measured on a nanoVNA. The nano VNA was calibrated for to 50kHz to 3MHz range prior to taking the measurements. As others have stated, 60dB of attenuation is a exaggeration. But it does attenuate signals from the AM broadcast band enough to be usable. I used the filter with an upconverter and also with a SDR receiver with direct conversion. Once the filter was put online all the aliasing from local AM broadcasts was removed. As I only looked as signals above the AM band I can't report on its effectiveness on the LF and MF bands. I am happy with the performance of the filter and would reccomend it.

## Features

- A high-quality, high-performance bandstop filter designed to attenuate broadcast AM for software defined radio (SDR) applications. Bandstop design means the filter will pass DC (bias-t power)
- Makes a great companion to the Ham It Up or Ham It Up Plus upconverter! Distill:AM will also greatly improve performance of RTL-SDRs which utilize direct sampling hacks to receive HF
- Distill:AM has its filter circuitry fully shielded with an EMI frame, and has its front end protected by an ESD diode meant for RF applications
- -3dB rolloff frequencies: 350kHz & 1900kHz; attenuation (typical): 40dB; DC current handling: 250mA (min); AC signal level handling: +18dBm (min)
- Designed and manufactured by NooElec in the United States. Full 2 year product warranty direct through NooElec

### ⭐⭐⭐⭐ Light filter.
*by C***R on February 2, 2020*

Found out that the filter passes DC and can be connected from either end. Not sure if that’s ok with the DC pass? The filter is very broad 480-2000khz and does help listening in the lower hf band if near a big AM station. Not helpful below 400. Well built and recommended but you’ll need two or three in line to get full results.
