    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    APX7000XE noise cancelling option

    I understand the APX7000XE has rather good background noise suppression technology. I recently bought an APX7000XE and would like to enable the noise suppression on my digital channels. I watched this video (https://www.youtube.com/watch?v=bUxAw55O1rg) on youtube and was fairly impressed. I...

    MTS2000 Tx fine but receives only noise

    Hi all you good guys, I have 5 MTS2000 VHF radios. Before I tried to program them, they worked fine. The problem was that I did not have the license to operate them on those channels. So now I have programmed one frequency in. I have cloned all of them. Now when I turn them on I only hear...

    My Beverage antenna is NOISY! Why?

    I built a single wire 40Meter Beverage pointed towards the N.E., 1.3 wavelengths long and 10 feet high (above "antler height"), and it is far noisier than my full length 40M dipole that is up 50 feet. I just can't figure out why; I am using a DX Engineering matching transformer that is...

    Yaesu: vhf noise

    So I recently installed a new yaesu 2900 and larsen nmo150 antenna in my truck to monitor two meters and some utility frequencies. It seems to work good except on certain frequencies it picks up a lot of noise and on others it doesn't. This radio has a squelch knob which helps eliminate the...

    Avoiding Control Channel Data Noise

    I just programmed my PRO-652 and my PRO-96 scanners using the Butel Software with local frequencies. Almost immediately I began hearing what I will call control channel data noise (buzzing sound) and the scanning stops until I scan again - and then it occurs again within a few seconds. I am...

    Police Channel Noise

    I'm a new scanner owner (BCD996XT) and have a question regarding issues I'm facing trying to pick up my local police signal. I've configured the scanner using FreeScan and RR import functions for my city/county. I'm able to successfully receive channels for the county sheriff and fire...

    Scanner receiving two frequencies at once.

    I have an Icom Scanner with an SJ-118 antenna. It is tuned to 119.75MHz (Monterrey Approach and Departure). If the squelch is open it receives the signal of a local FM radio station (107.7MHz). How do I go about filtering that so I can open the squelch a little more to get what I really what I...

    Squelch Tail after analog trunking transmissions

    I loaded up my BCD536 HP using zip code, and it is correctly scanning both the local trunked and conventional systems. There is an annoying squelch tail (1 sec long and LOUD) after analog trunked transmissions. I did not have this problem on the HP-1 or my BCD996/396 series. Is there a menu...

    SDR# (rtl2832) signal noise calibrating to peak signal.

    So, I'm trying to calibrate my NooElec RTL-SDR RTL2832U & R820T for SDSharp, using the stock antenna, which actually gets pretty darned good reception. Problem is, upon calibrating my signal, so it sits center of the peak, I get this high pitch noise. If I readjust the signal so it sits a bit...

    HT1000 Weird Squelch Noise?

    On a single channel on my older UHF (450-520) HT1000 there's an intermittent noise, similar to the sound of the squelch opening. The noise occurs about once every two seconds, and lasts for about one second. Upon comparing the noise to the actual squelch opening, it sounds softer. The sound does...

    USB AUdio adapters

    So I bought some of those USB audio adapters that are all over eBay and I'm disappointed. There is a large amount of noise in them and I don't see how I can use them without getting hate mail from listeners. I tried direct connect and hub with no difference, the audio is terrible. Is anyone...
