[let's cut the BS] Then, on the top of your desk, cut a piece of copper foil which is self resonant to ~27Mhz; construct it so the operation of the mouse is always over this plate. I will guarantee you, your range will be extended!, and, noticeable so! Warm regards, and, thanks for the mental exercise! JS |

hi there, i read an article(link below) on adding an external aerial to a PC mouse to improve its transmitting ability using a twist tie to its front http://lactose.blogspot.com/2007/06/...prove-its.html but it didnt improve its range. i figured you ppl here know your aerials so i was wondering if you could give me some ideas to try. this is what the mouse looks like (RF board is one on the right). thx http://www.geocities.com/ymailus/mouse.JPG (i can upload a hi res one if anyone needs it) s Sorry I'm late, we were away for Xmas. One thing already suggested is somehow making electrical contact between your body and the antenna terminal so your body acts as a larger effective antenna at the mouse. I wouldn't worry about any impedance mismatch between the RF portion of the mouse and your body, power levels are so low you won't damage anything. Another thing is making the antenna at the PC bigger, like maybe a full wave loop of #36 magnet wire strung up the walls and across the ceiling and coupled in to the dongle by wrapping it with a few turns of the loop wire. Different orientations of the loop may give you better performance. |

[let's cut the BS] "John", as a result of this and several other posts, I am joining a growing list of people who have plonked you. I guess when you post in anonymity, you can say anything you want...anything goes...from the just plain stupid, which is marginally tolerable considering the damage that the lysergic acid must have ravaged on your right frontal lobe in your early years, to the dangerous, including your casual mentions of past drug use by substance name when you know there are kids who read this forum. I wouldn't want my teenager reading some of your posts. The ng isn't just about you "John", or the poor image you continue to profess about the amateur radio community in many cases when you post here. You wouldn't be posting the very stupid things you write if you were exposed to the embarassment of using your real name, yet you write in such a way as to attempt to exude guilt on those who criticize you, as if there were a real "John Smith" to feel sorry for. Your persona name is nothing, it is vapor, and I do not want to waste any more time on vapor. So I agree, let's cut the BS (I just did so, permanently). |

[stuff] In fact, just remembered how much the copper was going for in the scrap yard--in place of "copper foil" use aluminum foil ... Regards, JS |
