interference

Hi all, I have a narrowbanded Yaesu FT-2900r that I have scanning some railroad frequencies in the area and within the past year, it has started to develop this unusual interference. I've included a link in this post so everyone can take a listen. The entire setup consists of a dpdproductions...

I've just started exploring radio, and I'm totally captivated by how it works and what you can do with it. Unfortunately, I'm so new, I don't know if my setup is working well - maybe I'm doing something stupid like using the wrong antenna and don't know it - so I'm asking for some general...

Hi, I am located in cass county, MO. I do church security and I am in need of some good frequencies to use. The main radio the team uses is the Baofeng BF-888s and I personally use the UV5R. We need something that will work well through brick walls and auditoriums and be legal, plus we need as...

I just recently purchased a bcd325p2 and I have been trying different bands and systems with it. Most work just fine. But for railroad, which I really want to listen to, the whole band goes silent when I turn on my home build desktop computer which I built a couple of years and has a top of the...

Hi all, I became the owner of an ICOM-R75 awhile back, great radio, love it. There seems to be one problem though... Right now the antenna I'm using on the R75 is a Par EndFedZ, seems to work well with the radio, it is strung up about 45 feet. But when I'm scanning through frequencies, every few...

Trying to find the station/transmitter causing interference on 158.9400MHz possibly operating out of North Central Idaho or the Idaho Panhandle. The station is transmitting with a CTCSS Tone of 179.9Hz. No voice is ever heard and no CW ID or other station identification is heard. All I can hear...

I have a Motorola XPR8300 VHF Analog Repeater without an external power amplifier that all of a sudden has a lot of background interference or noise. The repeater is on a mountain top however a long ways from any other transmitters. It is the only radio repeater at its location. It is used for...

I live in Maplewood and monitor the PD on 154.815 with a Pl of 114 I think, if memory serves. Ive noticed that a Hunterdon country dispatch uses the same frequency at a different Pl tone, it's so close that on my home base it comes in full scale and on HT about S3. Why would they use the same...

Hello all, I do not know too much about radio installs so please bear with me if this is an obvious problem. A group of myself and others work together in a photography business, and we recently decided to take our operations efficiency up a notch by renting a radio system. We are utilizing...

Hi! I recently found my oldish Grundig G5 receiver, and thought it would be fun to start listening to shortwave again. I used to live in the country and I had decent reception, but since moved. The antenna was very loose and I had terrible reception. The rubberized coating had also become...

I am trying to duplicate a problem with my radio - an ICOM R-8500 tonight with out luck. I purchased it in 1999. Are there jammers that will block an extremely wide area of bands? Below is a copy of my email to ICOM about my issue. The key work at the end of my paragraph is "intermittent" which...

Found this lately on my waterfall on SDRSharp. Was wondering if anyone out there may have come across it in the past. Its from 143.945Mhz-145.067.

I have a multi-tier cell phone tower within 200 yards of my home witch interferes with my scanner. To monitor the 800Mhz band (e.g., police frequencies) I must sit on my front porch, placing the house between the scanner and the cell tower to receive transmissions. Is there a way to block the...

Not sure if my previous post was removed or was not approved by the mods to begin with, so my apologies if you're reading this twice.. I'm a new user, not a spambot, I promise! Anyway, my original question was regarding a continuously open mic on CB channel 19 (27.1850 MHz) near my residence...

I'm having an issue with crosstalk or interference on the primary frequency used by local law enforcement when scanning with my 92xlt. Freq. Is 154.86. Sometimes, I hear the local noaa wx radio walking on transmissions from the le dispatcher, only. This is frustrating, as this is the primary...

although i have had a home scanner for 20 years or so, I'm new to scanner on my android cell phone. I'm using the Scanner Radio app and I keep getting a chirp or clicking sound about every 3 or 4 seconds some time 6 seconds, the status of the feed is idle with no talking going on. I tried...

We are picking up serious digital interference in the bowling green area. On 153.440- we are convinced that it is digital noise. We are getting reports from muhlenburg co. Area of the same "jackhammer" noise. Anyone have any thoughts?

Recently I have noticed that in the evenings, it's not uncommon to hear loud intermittent zapping noises on the police scanner, covering some officers transmissions, sometimes completely. I didn't think much of it until I realized that no matter where I was in the county, I still hear it, as do...

Well, I woke up to this crud on the radio this morning :-( The strongest being centered around 7.4 mhz. I ruled out anything local to my house by killing the main breaker, the RFI was still there. Note the "DNA" pattern in the first image - anyone recognize it? It sounds like constant...

I've got this strange issue, well maybe not so strange to hardcore scanners, but to me it's got me puzzled. I know what's causing it but the static is really bad. This happens only when I've got my main cpu on. But it doesn't happen every single time, only some times. I've uploaded an audio...
