X phase 2 qrm eliminator

The QRM Eliminator is based on a totally innovative concept and cannot be compared to the performance of noise blanker or DSP circuits. Removing the noise before it gets to the receiver is the superior method of interference reduction.

If you live in the city or close to industrial facilities, you probably have high RF-noise level on your HF radio receiver from local sources that causes interference and difficulties in receiving weak radio signals. The solution is either to go out of city, in rural area far from RF-noise sources or to try this practical device and reduce or eliminate the local noise. It really helps so that you can listen many more DX stations that are hiden in the ocean of noise. The QRM Eliminator is inserted between transceiver and the antenna without any additional modifications to the radio. An additional auxiliary receiving antenna is required. It can be simply a few meters wire in the shak or outside. The unwanted signal is received with both antennas.

Very easy to adjust - very coarse adjustments - extremely effective without needing much skill to operate - better results than DNR could ever hope for.

It would be easy to smarten up the exterior.

I found out that the antenna for receiving QRM, the auxiliary or secondary antenna, holds the key to optimum performance of the QRM eliminator. A single wire along a shelf in your shack is, for what I tested, not enough. There is one specific antenna that does an amazing job. First of all I need to explain about my antenna setup. My main antenna was a 13m 31 ft tall vertical. This antenna setup allows me to work on all HF bands.

If you see figures regarding solar activity, you could conclude that we are very close to the start of a new solar cycle. That means within a few years my beloved 10 meter band will open up again for DX. On 10m even up to S9. I wanted to tackle this QRM without my neighbor having to shut down his solar panels. By coincidence I ran into a video shared by an old radio friend in Switzerland. He demonstrated a QRM Eliminator. I always thought that these devices were not very effective, but I was impressed by how he just turned the QRM away. Good to know is my radio setup. Antennas are a 13m tall vertical with a CG remote autotuner for m to 10 m and a horizontal dipole for 6m band. Radio is hooked up to a laptop for digimode and remote control over the internet.

MIle Kokotov, M. Add to Cart The item has been added. That being said, I ran a 4 meter 17 ft wire across the edge of the ceiling as an auxiliary antenna. Rating: Time Owned: Great! Good bandwith and sensitive to QRM Few years ago, when the noise from the solar panels came banging in , I experimented with different antennas for HF reception. Product reviews are not a Forum for two-way exchanges, inquiries, general discussions, complaints, help requests, product repairs or modifications. I could double the length of the whip to cover the longer wavelengths, but that would negatively affect the shorter wavelengths bands. That sounds like… Sounded like the ideal aux antenna That sounded like the ideal aux antenna for a QRM eliminator! One of the antennas I wanted to experiment with, was a Miniwhip. The solution is either to go out of city, in rural area far from RF-noise sources or to try this practical device and reduce or eliminate the local noise. In that case, The AUX antenna has to be changed, moved or modified. It works! Time Owned: 3 to 6 months. During rain, the noise is not present and my atmospheric band noise is S3. If you want to get that pesky noise floor down, especially if you live in the subs and have a gazillion devices screaming on HF.

The QRM Eliminator is inserted into the feedline from the trx to the antenna without any additional modifications required to the radio. Many Radio Amateurs, new and old, suffer from man-made interference that renders the HF bands useless. The delay can vary from minutes to a day or more. The 13 m vertical antenna covering meter to 10 meter band. Name Required. Edits will go thru the review Approval process. Increase the bandwith so it produces enough signal on all HF bands. I can take a S9 plus 20 db noise and reduce it to just about nothing. The CCD is typically a quiet antenna that's close to loop levels. In that case, The AUX antenna has to be changed, moved or modified. As all 3 knobs interact with each other, the adjustment can be a bit tricky, but at the end, the result can be great, so that we can hear many weak DX signals that we couldn't hear without this QRM-eliminator due to high local noise level.
