I got a laugh out of finding out so many people who "know" radio stuff, never heard of the microwave screen thing, except Hc714. I cheated though, when I still drove truck, I had a pickup at the Amana plant over in Iowa one time, and asked one of the people there what it was that stopped the...
Yes, reflection rather than just blocking is more logical. I do not think it absorbs them, although it might. But without grounding, it would charge up. Maybe it does, then leaks off slowly. I mean, it's not like I am overworking it by talking for long stretches.
This morning, I took a closer...
Only morons argue with the facts. The fact is, the screen works, and until you try it for yourself, you are never going to really know. Maybe take all that tinfoil off your heads and try that. It should also block RFI and you all have proven it's wasted on your heads anyway.
It's not grounded and it's not a fluke. It's worked all afternoon within inches of the radio and nothing. Before the screen, one click of the Mic and bam, lockup, restart.
Do you know how the screen in the front of a microwave oven works? Simplified, the holes are too small for the radio waves...
Just wanted to share my successful fix for curing radio interference from my wireless mouse and keyboard to the radio. I would hit a key or move the mouse and hear static on the 2985dx. Even worse, if I had the amp on and keyed up, the mouse would freeze, the computer would lock up and not even...
Probably the biggest of all reasons mentioned here is the radio. All I have is practical knoledge here, but I saw that it's mostly in the radio when I replaced my Uniden 980 with the RCI-2985dx. Sure, much different quality radios, but even so, the difference in RX was just shocking.
Nothing...
Wow, just found this one to add. A very nice site about the Sun and Sunspots. http://www.spaceweather.com/
I like this one: How Far Is It Between
I also use this now and then for more details: Calculate distance and bearing between two Latitude/Longitude points using Haversine formula in...
w9cll, I am not saying anything personal, it's just my own opinion as clear as I can make without pussyfooting around the issues.
I have been enjoying it since the late 70's and even I can not understand why I have no personal interest in the other bands. It does sound a bit weird, cause my...
CB is a poor and busy man's hobby. I do not have the time or the inclination to get any kind of ticket or add myself to any government hit list by being a registered user of a radio. And I certainly do not have the money to ever buy the high priced equipment or antenna masts and tops it would...
And how are you supposed to know how far you are talking? What if a guy just uses a number? Are you supposed to know where he is without any more information? What if he is lying and says he is in China?
And, let's get real for a moment, shall we? When you're signal goes out, you can't put a...
Both my Uniden 980 and the RCI-2985dx have jacks for headphones. You can also use the external speaker jack for phones. Better not get caught driving with headphones on though. :)
OK, here's an update. Skip just opened up a bit as the sun went down. 308 North Texas just boomed in here like he was out in the parkling lot. We talked for 4 minutes. Not real crowded now for some reason. I think I made a good change to my antenna at this point, thanks to this thread and...
My Balun on the dipole makes a flat SWR with no amp powering it. I mean 1.00:1. It has to be horizontal, both legs out to the sides "opposite" each other. If I do an Inverted V, with the legs "Opposite" each other, still good. But, If I have the legs at a 45 angle down, but both forward of an...
Sorry it took so long. I just pulled one end up that pole, and I would say it worked fairly well, cause right away, I pulled in a Toronto station, which is very unusual for me here. I never talk North of here, partly cause to the North of my antenna is an 18 or 20 foot tall steel highway...
Is that a typo? You mean the vertical is quiet?
I know my horizontal always has a lot of static.
Either way, tomorrow I am going to try it in a vertical, to see how it works. :)
Good idea. I know Homer to talk to and he knows his business. I'd also like to talk to someone who uses one. I am quite impressed what mine can do in a horizontal or slightly sloped configuration, but never tried it vertical like cjruger has his. I think my pole is tall enough, but the bottom...
I'm even worse off than cjruger. I don't have the tree, I do have an old bare telephone pole though, that is 18 feet tall and close to my rear window that the COAX goes out. And I have a lease that says no antennas. I like the idea of an end fed dipole, but can't make sense of the descriptions...
I'm curious, how are you getting out now? Do you get a lot of good skip?
I use a half wave horizontal dipole that slopes a bit to the South. It's no more than 17 feet high on the high end and slopes to about 15 feet. I am still very impressed with it, but I just can't talk or hear anyone...
