Unbelievable Cobra 148GTL 25 Watts 300% Modulation, Better than a Cobra 2000GTL... Seriously ???
Satire, Satirical, is it real? Maybe.... YOU HAVE TO SEE THE END, FUNNY Read all the description below to learn more. Yes, this can be real, it is real in this video, but in the real world most people don't have a 15 Volt system in their vehicle. Yes most vehicles charge at somewhere from 13.8 to 14.4 volts, but that is right at the battery, and that is rarely the voltage seen inside at the places where most people connect their radios. There is almost always a significant voltage drop by the time all the accessories are turned on and the voltage finally gets to your radio. I made this video to help people understand the significant power output (wattage) difference that will happen when the power supply voltage is changed that is supplied to the radio. Just by changing the power supply voltage by a couple volts can change the power output by up to 40% or more. This is a common way that some unscrupulous "radio tuners" and radio shops RIP customers off. There is a local shop here in Southern California that shows people their radio doing X-watts on the bench and then they drive off happy and bragging about their X-watt radio. Then one day someone puts a meter on it and it isn't doing X-watts, it doing a lot less. I had a friend drive straight to my house from a radio shop just off of Milliken Ave in Ontario next to the truck stop. He was bragging to me about his X-watts. I told him it was bull pucky and so we brought out the watt meter. It was putting out a lot less than what he saw at that shop. He was upset, so I told him lets take it in to the bench. On the bench it did the same power as in his vehicle, that's because I have my power supply set at about 13 volts. I cranked it up to almost 15 volts and guess what? The magic X-watts showed up. A simple 2 volt difference was almost exactly the difference from 75 to 100 watts. 75 watts was exactly what the radio was supposed to do, but the tech that charged him to "tune it up" showed him 100 watts. I don't know how these crooks sleep at night. This happenes every day, and not just at this shop, they are everywhere. So in this video what you see and hear is really me making fun of those thieves and hopefully educating some people so they do not get ripped off. Make sure you see the voltage on the power supply when picking up your radio. Maybe even take your own volt meter and watt meter. Ask to see the power after it is installed. Yes !!! in this video I really do have this Cobra 148gtl doing 21 watts of clean 300% modulation, but it is at 15 volts, and 15 volts might be just a little higher than you should run these radios at full time. You're gonna go thru some meter lights and make the outputs really hot! When you see it at 25 watts that is a real meter reading also, but it's crap distortion all over the place. Once I turn the power supply voltage down to a real world scenario, what we get is a little over 200% modulation at 16 watts. This is what I feel is a best case scenario for a Cobra 148gtl in most mobile environments. This 148gtl has been modded with the Finals Volted and with the NPC/RC mods, and had the modulation limiter removed on AM. It does sound beautiful on AM and SSB. Like I said before, the 15 Volt results are real. With that being said, these 148's and the Cobra 2000GTL Base Stations have almost identical boards inside, and both can be tuned with just about all the same mods. The difference is that a Cobra 2000gtl has a built in power supply, and just like you see me change the voltage in this video, the 2000gtl has an adjustment also. That means when you take your radio to the "radio man" he can just turn up the voltage and suddenly you believe he is a radio god. Don't be fooled, your radio will run hot and all your meter lights will burn out and then he can sell you some LED's. Then your capacitors will go bad, then.... OK, so leave some comments
