Uh, not quite. While the X Band police radars are at 10.525 GHz, the ham band is only from 10.000 to 10.500 GHz. Plus, pulse modulation is not allowed on the 3cm band. We CAN use MCW, phone, image, RTTY, data, SS, and test modulations. Hmmm, I wonder about plain old vanilla CW??? I don't see it mentioned...maybe "data" covers that nowadays (and with a bandwidth limit of 100 KHz, we could smoke along at a LOT of WPM!!). Scott N0EDV CW is almost always used for beaconing to align antennas. SSB is then often used for the contact, however CW is used if it is marginal. Just like HF, VHF and UHF contests. The major difference is that the transmitter will often drift a couple hundred hertz during the QSO. ![]() I have a few audio clips from the 10G cumulative contest last fall. If anyone is interested I will email you a link. Also see the article in this months QST by Jon Platt, W0ZQ. tom K0TAR |

Where the heck do you get a 3cm transmitter, though? ha. http://www.downeastmicrowave.com/ And you can easily do 200KM on 200 mW, or 1000 KM per watt with a Dish Network (or equivalent) antenna on 10G SSB forward scatter. tom K0TAR |

Yes you can. Check the back of QST for a complete 3cm station. Cost is about $500 or so. Dave WD9BDZ |

Sure you do...from the link Tom provided. DownEast offers the
"transverters" in kit or built form. Tons of us are using their equipment ![]() up there.

Not to mention the
Laser detector shield (as advertised on radio) (Which as near as I can figure, "Modulates" the received "radar" signal, to a LOW frequency AM signal to a dopler radar . I.E. a "RADAR Caliberator" ! Banned in 6 states!

Oh, that's an easy one...(Gunnplexers come to mind for a simple CW 3cm
transmitter) http://www.downeastmicrowave.com or http://www.shfmicro.com and there are probably a few others...

Hi, What's all this business I hear people talking about blasting people's car stereos or killing cars altogether with high-power RF? I run 2m, 10m, and 11m in my jeep and I'd like to sort out the fact from the legend and find out what kind of power I can use without risking damage to my jeep or cars around me. At what power level is front-end overload to a nearby radio likely? At what power level is damage likely, and to what componets? I am currently using only 50 watts on a 5/8 wave (2m), 25w on a 1/4 wave (10m), legal 4w on a 1/4 wave (11m) Thanks, Nelson KE5MBX I think over 100W you may have problems with HF and VHF. It can be a problem. One thing that works real well is to transmit near the x-ray radar band where you have privileges. The traffic may slow down a bit as you set off the radar detectors :-) Where the heck do you get a 3cm transmitter, though? ha. |

Think you meant "X" Band (10 GHz). I don't think many of us are using
x-rays for communications... Scott N0EDV Stefan Wolfe wrote: "KE5MBX" wrote in message ups.com...
