    Cobra 148 GTL Meter Part Number

    The after market and OEM part numbers makes sense. As long as it's accurate "enough" for normal operation then that's all I'm worried about; let me know if there's any major problems with my antenna, let me see whether I'm modulating properly, how strong incoming signals are, etc. I've got an...

    Cobra 148 GTL Meter Part Number

    I've got one of the newer Chinese made Cobra 148 GTLs with the front facing microphone plug. I've used the thing for a decade or more now and the meter has gotten slightly deformed from the heat of that incandescant bulb so that the needle is stiff and doesn't move properly. I've found the...

    Quad Bay TV Antenna

    Haven't gotten around to purchasing a different antenna because I've been working and doing other things and this one works pretty good for pulling in the kids' cartoons and the local police/fire radio traffic. Today however I did manage to get the TV antenna off the porch and mounted onto its...

    Quad Bay TV Antenna

    Interesting lesson learned from experimentation today. I have a quad bay UHF television antenna. I use it along with two in-line signal boosters to power my police scanner, two television sets and an AM/FM stereo. We get 3 channels for free from a PBS tower about 30 miles away as the crow...

    Wavelength Calculator

    I wrote myself a simple wavelength calculator in Python. I did so for two reasons. 1) I wanted something installed locally that didn't depend on internet access that allowed me to just click one icon, punch in a freq, and get some numbers back. 2) I wanted to tinker around in Python. I...

    cobra 25 nw wx st power mods

    1) 4x the carrier strength is 100% modulation. Anything more than that is wasted energy and will either cause you to splatter or will actually start to distort and hurt the quality of audio coming out of the radio. 2) Spreading coils might make a meter show more watts, but they're all over the...

    Home Made Antenna "Tower"/Pole

    My Cobras are all newer front mic radios. He's using a Uniden Bearcat 980 SSB. I've heard bad things about the newer Cobras but mine have all been great radios with one exception. The one in my wife's car has a sort of warble on SSB that you can't seem to clarify out. The one in my truck and the...

    Antennas and DC Shorts

    That's good to know. I ran a little Power Deluxe 25A power supply/amplifier for about a year (ran short of cash and needed money) and SWR never moved on it, but I turned the radio input down to about 1 watt (swinging to 3.5 or so with modulation) and all was well, but I never considered...

    Antennas and DC Shorts

    I recorded this video kind of in a hurry in response to an ongoing debate on Facebook. You'll have to excuse the poor video quality, I replaced my old tablet and the camera on this one is less than impressive to say the least. I need to invest on a dedicated camera. I'm posting this because I...

    Home Made Antenna "Tower"/Pole

    So my brother recently bought a house and a piece of land in the next county over. The house is on a knoll in the head of a holler, and although he is in kind of an open/high spot relative to the rest of the holler, it's still a holler and has some hills on all but one side of him. So he...

    CB Radio Mobile Setups

    Thanks for the feedback, :-) I always assumed the bed and everything was already "bonded" since it's bolted to the frame, as well as the cab, but I'll definitely take a look at the page and see what I can do to improve it. I had thought about putting some ferrite chokes on the coax to help get...

    CB Radio Mobile Setups

    I've got a base setup, also a Cobra 148 GTL. There's a video on my channel of the setup, but it's a year or so old and I've made some improvements since then. May record an updated video here in the next few days.

    CB Radio Mobile Setups

    I've got two mobiles, one in my 1999 Dodge Dakota pickup truck and one in my wife's 2006 Ford Taurus. Both vehicles run Cobra 148 GTLs (we generally use single side band when it's just the two of us). My pickup uses an oversized stud with a 6 inch spring and a 102 inch whip. My wife's car...

    MURS

    I've thought about getting into MURS. I've got a little 2 meter Baofeng UV-5RV2+ that will transmit and receive on the MURS frequencies. I've plugged the MURS channels into my scanner (outside dual bay VHF/UHF antenna) and I'll let it run through those as part of its normal operation and see...

    Rf noise

    Just make sure you've got a good solid ground. Even with a solid ground though, sometimes interference from your fuel pump or spark plugs will travel back down the shield on your coax or down your power cord and cause interference. SSB will make existing white noise a little bit louder...

    groundwave talking?

    My base station uses a Solarcon A-99 on a homemade pole on my back porch. I'm in a low spot between two mountains, but there's several hundred feet between me and the mountains on either side, so it's not as bad as it could be. The highest tip of the A-99 is 41 feet in the air. When skip...
