I don't have any particular radio that has this problem. But I have had them in the past. Icom 02at, Yaesu FT-5100, for example. These were not so bad that you could not use them. I see radios all the time that have this problem and was just wondering if there was a fix. I prefer the older radios that have a real mic connector. A rj-45 just does not last very long while run mobile. Whenever I buy a used radio I usually replace any burnt out bulbs with leds, and thought if there were a fix I could do that while I had the radio apart.

Anyone know if it is possible to fix "bleeding" on the display of a radio. I searched on eHam and came up with nothing, although it may be called something else. I don't mind doing the research, I just don't know what to search for. It is a case of not knowing enough to know what to ask. Thanks

eHam Forums / Misc / Adding an external antenna jack to a tablet

Has anyone ever tried to add an external wifi antenna jack to a laptop, tablet, or an netbook. I don't have any problem with a wifi signal and I am not planning to do this, but do find it interesting. I guess it just comes natural to want to improve your signal. I thought it would be interesting to do the same thing to a cell phone. I would love to be able to add a good external antenna to my cell. How I do miss the old phones that had that feature. Why is it the best cell signal I ever got was from 18 years ago. Must be that real antenna. I have even thought about how you could add an external antenna to a garage door opener to get better range when installed inside a metal building. Check out the following videos, this is just one of many that gets the wheels turning. http://www.youtube.com/watch?v=2lRaXGSjro8&feature=player_embeddedhttp://www.youtube.com/watch?v=4lmmCctSvb4Anyway I would love any and all details if you have done this.

eHam Forums / Mobile Ham / RE: Where is the best place to drill antenna mount in Bronco 2

Sorry I took so long to respond. Internet has been down at the house.
Finding the support ribs should not be a problem. I can get to to it from below. How far apart should I drill the holes? How far do I need to stay away from the edge of the roof? I thought I would drill the two holes down the center line of the roof, one right behind the sunroof and the other centered between the first and the roof edge. Does this sound OK? Am I correct that the 8" of metal around the sunroof will be OK for a groundplane?
Thanks again, Scott, KC4YJI

I have a bronco 2 that I want to mount a couple of antennas on. I want to drill 3 holes to put NMO mounts in. I want to place one antenna at the bottom of the windshield on the drivers side to match the existing am/fm radio antenna that is on the passangers side. The other two mounts will go in the roof. My question is where is the best place to put them. I am planning to use one of the three mounts for a scanner and another for a 2 meter radio. I plan on upgrading the 2 meter to a dual bander soon (2m/440). The third will be for the future.
I live out in the country and talk mainly on 2 meter repeaters that are about 25-35 miles away. I would like to leave my options open for a future radio; hf, 10 meters, 6 meters, 220 etc. I plan to use a 1/4 wave antenna cut for 146 MHz for the scanner.
This bronco has an aftermarket sunroof installed. The roof size is about 44 inches wide by 80 inches long. From the rear of the sunroof to the rear of the vehicle there is about 54 inches of metal. There is about 8 inches of metal on the front and each side of the sunroof.
My questions are...
1. What are the dimensions that would be best to locate the two holes in the roof? 2. Which antenna would you put on which mount? 3. I have both a 5/8 wave Larson and 1/4 wave, which would be best for the 2 meter radio? 4. When I do up grade to a duel band, what antenna would you suggest? 5. Do you have any other advise or tips?
This will be the first time I have drilled a hole for an antenna. Any help will be greatly appreciated. Let me thank you in advance for you time.
Scott, KC4YJI

eHam Forums / Elmers / RE: Belden 89907 coax cable

Thanks for the replies. I think I will try it and see how it does. I am basically just trying to get an HT antenna above the roof to hit a few repeaters. This will save batteries and I can leave this cable there with no worries if it gets damaged. I hate to spend money on something that will hardly be used. The rest of the cable I'll just use on HF.

I have about 85' of Belden 89907 RG58a/u (type e34972) coax cable that was for Ethernet. It is new and has a BNC connector on each end. I was thinking of cutting it in half and using it for a couple of antennas that don't get used a lot. One, at my parents house, a homebrew dual band ground plain 2 meter/440 mounted just above the roof. Maybe another portable antenna when I go camping (coaxial dipole). These will only be used about a week each year. I did not want to buy something when I have this in the junk box.
My questions...
1. Is this OK to use for 2 meter? 2. Is this OK to use for 440? 3. Is this OK to use for HF? 4. Is it a OK to use a PL-259/SO-239 with 440? I have heard otherwise, but notice this is what many radios have on them. 5. How would I put a PL-259 or BNC connector on it being that it is slightly smaller than RG 58?
I would like to use this as it already has a bnc connector on it. I will be using it with a HT most of the time, although a mobile at times. The longest run will be about 25'. Thank for your help.
