P25 PM/FCC BK M150
Using a General Dynamics R2625 service monitor I demonstrate in this video how to do a basic preventative maintenance check on a P25 mobile radio.
Transmitter- power out, frequency error, deviation and Tx BER
Receiver- Rx BER at rated rf level
Any user complaints or deviations from doing these tests then a closer look can be made.

Never Scan, Only Priority Scan
มุมมอง 66หลายเดือนก่อน
In this video I demonstrate the difference between Scan and Priority Scan. Scanning channels with a Public Safety Radio can be dangerous because important transmissions can be missed if care is not taken to ensure priority scan operation only. During regular scan an active channel is locked on until the end of the transmission, regardless of activity on other channels. During priority scan the ...
Using an Analog Radio and PC to make a P25 Digital Receiver

In this video I demonstrate how a Kenwood analog radio in conjunction with a PC running DSDPlus Software can be used as a P25 receiver. The C4FM modulation signal behaves essentially like an analog signal for an analog fm receiver. There is no distortion or other changes. The only thing needed is a 4 level decoder, and then the codec package, which the DSDPlus software and sound card accomplish...
Troubleshooting Mobile Radio RFI (Radio Frequency Interference)

In this video I demonstrate how a bad ignition coil in a 2013 Ford F250 was producing large amounts of RFI between 50-200MHz severely de-sensing a BK VHF fire radio installed. Using a low rf level NOAA weather channel as a reference, I show how after starting the engine the channel became unintelligible due to the interference produced by the truck's engine. This effect can also be shown using ...
P25 Radio Tone Detection & Regeneration
มุมมอง 1623 หลายเดือนก่อน
In this video I demonstrate how P25 radios with tone detect can pass steady audio tones, but not sweeping audio. The mic input voice spectrum from 300-3000Hz is virtually divided up into 31-61Hz windows in the AMBE 2 vocoder, where any tone sent within that window of frequencies will be regenerated at the receiving end at a predeterminded frequency. For example any tone that is transmitted betw...
GPS Radio Link Without Wires

What started as a joke test, turned into something very cool with my GPS radio link. I found that I could play the FSK tones into a speaker and just use the radio's microphone held up to the speaker to transfer the data to the remote receiver. When I got the volume loud enough and the microphone close enough, the accuracy was very good. This is a standalone device that does not require being co...

No head/interface board swap like a Motorola. Make sure the firmware is the same version between head and radio.

    I know this is old, however, at 33:00m you say the c-soft output is UDP and goes out to all ports on the Ethernet switch - the former is technically correct, the IP 226.x.x.x address indicates multicast and is how UDP traffic could propagate to all ports, it is not phony. Otherwise, good video and much better than trying to read the install manual.

      I would want to do a double swap with a known good phone. Does the "bad" phone still not work when plugged in to a jack that usually works? And does the phone that is known to work show the same "bottom row only" effect when plugged into the original jack? My guess from those symptoms is that it's just a bad phone.

    • @dc95811
      @dc95811 4 หลายเดือนก่อน

      It is impossible to directly convert that without being able to control the sentences put out by the GPS, and the rate at which the GPS outputs the sentences. Too many sentences means too much data without enough time to get it out, and the buffer gets involved and then quickly overfills. So you would have to reprogram the GPS. But here is the good news. The GPS module can be reprogrammed for 4800 baud. If you look on page 36 of the mega spec sheet on the NEO-M8 at the link below, you will see 4800 is a selectable option. I know you have to use UBlox U-Center to reprogram the modules. I haven't done it myself, I'm a Garmin guy. But there is lots of videos on using it. content.u-blox.com/sites/default/files/products/documents/u-blox8-M8_ReceiverDescrProtSpec_UBX-13003221.pdf

    • @dc95811
      @dc95811 5 หลายเดือนก่อน

      There are a lot of things that have to be clarified. 1. First define what you mean by wifi "turns off". That could mean many different things. Is it disconnecting but staying enabled? Is it disabled? Or does it just not work? 2. If you unplug the ethernet cable, does the wifi automatically start working again? If not, what exactly do you have to do to get it working on wifi again? 3. The NCSI, the network connectivity status indicator, will always take ethernet control as far as what is seen in your task tray at the bottom right of your screen, that is because it wasn't meant to show 2 at the same time. But that doesn't mean wifi isn't connected at the same time and is working. I could just go on and on. But I think in answering these questions you would find the answer to what is happening. Think of it from the app's side, it wants this data and it has 2 choices from where to get it from, which does it choose. If it thinks it can only get that data from just 1 side it will always pick that side to get it. Task manager performance screen is the only real way to easily see what it is chosing in real time.

Now play a youtube video and you can see which is in control. Watch the video above to change from one to another using the metric setting. If you dont see both listed in Task Manager, then go into Control Panel/Device Manager to see what happened to either device.

    • @dc95811

      Thank you. No. BK has forbidden entry into the world of adjustments for anyone outside their factory. I see you found the "medium" mobile setting that gives you 50W. As far as licensing, those are rated for effective radiated power ERP measured at the antenna. Unless you have some super quality, or super short coax, you will more than likely drop that extra 16W before hitting your antenna. And then only a portion of that signal will be fully converted to rf energy, with the rest reflected back to be turned to heat on the radio heatsink. Put a wattmeter with a dummy load at the NMO adapter to test.

    Thanks Sir! I still remember the days of DC remotes being used for the primary dispatch “console” (Series 90? w/handset and Communications Specialist grey box QC2 encoders INSTEAD of using the integrated Motorola encoder in the desktop base of the Series 90) for the volunteer fire department I was a member of. I was 18 at the time and quite clueless about life and comms. The police desk was some 3 blocks away from the transmitter site located at a town building fairly high up in altitude. The clowns who sold the department their equipment was more clueless than I was. And that’s pretty bad.. They had an older VHF high-band Maxar 80 converted to a “base station” with crappy AC power supply and no power backup. The length of the 2-cond single pair telco leased line? 24,000’ ! A tad bit longer than the 3 blocks I had assumed it was. At the time, I had no clue that each telco circuit had to be run back to Ma Bells’s local central office. So, obviously… for 2 points, it’s each point’s distance to the CO plus the other point. I’m still surprised it worked!! Then again, it often experienced long outages while the NJ Bell (dating myself. LOL. The Bell Breakup was still a few years away). I ended up donating and replacing everything years later, but I still remember those days. Oh yeah…. Monthly charges for 2-wire copper leased line circuit? $200-220 /month ! Compared to today,.. sorry not available anymore. Same with POTS “dial up” for fire alarm monitoring systems.

It was a “shelf spare” with a few hours of use and is currently sitting in my garage - irritating my lovely wife who wants everything cleared out so she can continue “parking by touch” . 😆 Where are you located? I’m in NJ and have a ton of gear you might find interesting for your TH-cam channel .. Thanks again for a great and very informative channel.

    What a great channel! I still cannot believe I haven’t found it previously AND that the subscriber count is not 5,000,000 + Thanks!

      Thanks. I wanted to do a channel for radio techs, and also be able to present training for work purposes. I was hoping when I started it would inspire other techs to start similar channels. If you look at mechanics or hvac or other trades they have a good representation. Radio techs, not that much. People are nervous about putting themselves out there I guess.

    I was taught by a really old-school TV repairman. He was a family friend who owned a TV repair shop in the most ghetto part of the ghetto area of Orange, NJ. Our family owned a dress shop a few doors down, so you can guess where I would always visit.. especially during my multiple public school suspensions for acting like an ass when bored. 🫣😆 That was in the “10-4 Good Buddy” CB Radio days. He mandated tinned copper braid be used to bond the vehicle’s battery’s negative terminal to a clean and shiny metallic spot of the vehicle body. All doors, hood, trunk, etc.. all got “bonding jumpers. He taught me so damn much! How to do work I’d be proud to show others. How to treat people properly. How honesty and integrity would keep your business as busy as it could ever be. He would routinely allow customers to take home repaired items and allow them to pay when they could afford to.

      Forgot ->> That fine man, Paul Garafola, my mentor through my early teens through my post-doc work at RPI and through early life…. Was working late in his store on Christmas Eve in the early 2000’s. He had converted his TV repair business into a video rental and accessories business and wanted to be open for his customers. His body was found the next day when he failed to show up for Christmas dinner at his daughter’s home. His wife had died the prior year and he was just getting back to some normalcy and visiting family more often. A model BLM type had entered the store on Christmas Eve and beat Paul’s skull in with a claw hammer as he was literally begging for his life. He lie on the floor for hours, moving occasionally and seizing many times before his body was lifeless in a huge puddle of blood. The savage animal thug who killed him… walked away with all of $11. The scumbag was never located. The lesson? Paul took me shooting and taught me about firearm safety when I was just 10. My folks WERE far lefties and were terrified that if they had a gun in our home, it would get up and kill everyone on its own. They have finally grown up and are conservative patriots now.. Paul’s lesson? He had secured his UNLOADED pistol in a “lock box” to comply with NJ law. The frail 86 year old man just had no time to UNsecure the key to life. 2A. RIP Paul Garafola. 😢🇺🇸 The store was located in lovely semi-burned out Orange, NJ. in the PRNJ “People’s Republic of New Jersey”.

    That Stak-on is a crappy looking crimping tool. (in this video’s thumbnail) But… That crimper and T&B’s ratcheting crimping tool for insulated terminals were some of the best tools I’ve ever owned! For public safety radio installs (timeframe = back when the Motorola Micor was “super high tech” 😆), I used to crimp with uninsulated crimp terminals with mil-spec marine grade heat shrink tubing. BUT.. I also left the bare conductor slightly long and then added solder to the mix. That came about after many failed connections with crimped connections when I was using (ubiquitous at the time) Ideal combo crimp/strip/thread electrician’s multi-tool. After 35+ years, I’ve come to realize that a proper crimped connection, MADE WITH THE PROPER TOOLS and high quality connectors.. is nearly as good and much less labor intensive. Damn… I really AM old and ancient. 🤣 Thank you for sharing these videos.

    • @dc95811
      @dc95811 8 หลายเดือนก่อน

      Ebay usually is about it. They are currently sold out. It has an embedded circuit board inside the connector housing. Can't just make your own. Whatever you do, don't plug it into your computer until you have loaded the drivers.

      Thanks. The one I was using was from an old IFR service monitor. I can't find anything like it online. If I had to make my own I might use a Valcom VMT-2 with some coax pigtails. www.amazon.com/Valcom-600-Ohm-Isolation-Transformer/dp/B00OZDR1KA/ref=asc_df_B00OZDR1KA/?tag=hyprod-20&linkCode=df0&hvadid=642112814556&hvpos=&hvnetw=g&hvrand=1854126406178952501&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=1015150&hvtargid=pla-2003424720607&psc=1&gclid=CjwKCAjwvfmoBhAwEiwAG2tqzKrxOPCo5eBGW5lbjIJbAoCwsw5YFXl-MnvZr1mLPbb2TzZ2Lv5_5xoCfAYQAvD_BwE

    Where is GEC ? grounding electrode conductor that goes to ground ( grounding electrode). I am not sure if your local code follow NEC.

      It is kind of hidden in the video, but if you look close you will see the green ground wire being bonded to the neutral at the service disconnect.

    It's actually less than 1/10 amp that's returning via the ground conductor. It's only the unbalanced current. If the primary side was wired as delta instead of star, no neutral connection would be used.

    • @dc95811
      @dc95811 9 หลายเดือนก่อน

      I see. So if only 1 leg had a load you would need the neutral. But you can do the crazy 3 way load balance thing where all the current is kept within the primary feeds? The same way it works here at 120V 3ph drop, the same applies for the substation feeding this part of the world like a big 3 rail breaker box at high voltage.

      The neutral IS a current carrying conductor.
