    Sprouts Farmers Market Radio Frequencies

    It would mean that there isn't a radio license under the name "Sprouts". It may be under a parent company, or a radio shop, or some random name. There's a lot of companies that foist the two way radio stuff off on some random IT guy. Random IT guy googles/amazons "walkie talkie" and said IT...

    Some carmakers want free AM/FM out of cars

    As so often, the usual knee-jerk reactions from the RadioReference brain trust…. 1. Electric vehicles are not going away. If you don't like them, don't buy one. 2. Radios -can- work in electric vehicles. The issue is a combination of RFI, demand, and pushing people to subscription service...

    APX to XL 200 Migration (CPS to RPM2)

    People have been saying something similar for years. The idea of a common format that would allow transferring files between radio brands isn't new. But, no, no one wants to do it. Best you can do is pull info out via the software into Excel and import into the other program. Not sure if...

    Antenna advice

    If there's zero ground plane under the antenna, then it doesn't matter where you mount them. But I'd focus on getting them on top of the vehicle so they have a clear 360º view. Down below roof line is going to result in shadowing. Yes. A no ground plane antenna (usually a 1/2 wave design)...

    Ford Explorer Installation

    I guess I'm not understanding the question, then. Everything but the scanner is remote head, right? You'll need power at the dash for the scanner and Motorola heads. You'll also need to route coax, control, and power to the RF decks. Routing cables should be the easy part. You'd have to get...

    scanner on LAPD system found in burglary suspect car

    No, that can't be true! Fake news!!!! Criminals NEVER use scanners/online apps to commit crimes, and encryption won't fix anything. There's no record of scanners ever being used in a crime and "The Big E" is an infringement of my first amendment rights!!!

    Ford Explorer Installation

    I've never worked on a non PD one, so not sure if there is room under the second row seats. Mounting under there would be an option. 3/4 plywood mounted to the floor, rattle can paint it black. Other option would be to see if there's a gun safe type box that would fit behind the 3rd row.

    Ford Explorer Installation

    Most of those inserts will either rattle as soon as you put them in, or will start rattling after a few weeks. You'll drive yourself nuts trying to eliminate the racket. No idea if it'll work with the 3rd row, but I'd avoid that if you value your sanity (and that of your passengers). What...

    Antenna advice

    Tram is popular in the hobby world due to price. They have some good products, but I personally do not believe the minor cost savings is really worth it. I've been doing this professionally for a few decades and one of the things I learned early on is that the antenna is the most important...

    J Pole Grounding

    NEC is bare minimum. "It's not the ceiling, it's the floor" https://www.mikeholt.com/instructor2/img/product/pdf/17LED-1498-sample.pdf NEC is for personal safety. It doesn't address anything more than keeping the people in the home safe. If you want to get into proper RF grounding, and/or...

    J Pole Grounding

    This is proof that there are a fair number of hams that have no freakin' idea what they are talking about, and shouldn't be allowed to handle sharp instruments, never mind give advice on grounding. Just because someone is a "licensed ham" doesn't mean they know anything other than how to...

    APX8000

    Right, every good hobbyists knows that public safety agencies are wasting taxpayer dollars by not just buying the latest Baofeng radio for their needs. Or better yet, just install CB radios like "real men".

    NXDN to Analog patch

    Easier way to handle this is using mixed mode channels. It's designed to let you do a slow transition to digital. Or, load everything with analog channels and when everyone is finally cut over, move to the NXDN channels.

    APX8000

    Not a problem. These things are way beyond what most hobbyists comprehend.

    APX8000

    Multiband radios act no different than a mono-band radio. The officers don't usually know which band they are on, all they know is they select a channel and are able to communicate with someone. Every, and I mean -every- officer I know is already carrying smartphones, so no more temptation...

    Unselected deck mute when key up

    Is this for amateur radio use where there is a linked 2 meter and 70 centimeter repeater? I believe there is a speaker mute pin that can be set up on the DB25. You'd need to build a cable and set up the pins so TX on one radio would mute the speaker on the other.

    APX8000

    The PD really liked the look of the APX-Next, but not the price. And once I explained the cost of the backend support for all the cool apps, they get the hint. Motorola needs to keep the APX8000 around, but marketing might think otherwise. We ultimately purchased the Harris XL-200, and are...

    APX8000

    That's not the Motorola I knew. They were -all- about twisting arms. I looked at buying APX8000's a while back for our PD, and got the hard sell on the APX-Next. And I mean HARD sell. Everything short of physically twisting my arm.

    Deciding between Larsen BNCQ or Diamond RH77CA for BC125AT....

    Both are 1/4 wave on VHF. The Diamond, being it's aimed at hams, would probably already be tuned somewhere near the 2 meter band. The Larsen, being an LMR antenna, would work best if tuned for the 2 meter band. Both require a ground plane as they are both 1/4 wave on 2 meters, but in...

    Rain, coax cable and SWR

    This is the industry standard method of sealing coaxial connectors: https://www.telewave.com/wp-content/uploads/2016/12/TWDS-0502.pdf I've taken apart antennas that were installed in the 1990's and the connectors are clean, dry and look like new. The silicone tape is gaining acceptance, but...
