| 807617 | 2009-09-07 07:27:00 | Hi all. I'm looking to either buy or (preferably) make a (not so) small UHF amp, but google isn't bringing up much. It's for a small... project. It'll be operating somewhere between 470 and 700Mhz (maybe higher). Google isn't bringing up much other than small (1w) projects. I'm hoping to hit at least 50w, if not more. By the way, I have an old 600w car amp that has some power MOSFETs I might be able to use if need be. Can anyone recomend either a readymade amp or a good project one? Thanks. |

| 807618 | 2009-09-07 07:30:00 | I assume you have a licence? You can't run unlicenced on the UHF bands at that kind of power. | Erayd (23) | ||
| 807619 | 2009-09-07 07:32:00 | Um... let's say yes? | ubergeek85 (131) | ||
| 807620 | 2009-09-07 07:36:00 | Heh, well reading between the lines I'd say you're in for a pretty hefty fine and possible confiscation of your equipment. With that much power, you'll be stepping on other people's toes very quickly, and those kinds of squashed digits attract official attention. | Erayd (23) | ||
| 807621 | 2009-09-07 07:37:00 | Yeah, it was a bit of a long shot... I was planning on something like this (www.instructables.com) |

| 807622 | 2009-09-07 07:46:00 | Yeah that isn't such a smart idea here - unlike the US, our analogue channels are still live. Even in the US, it's not smart - you'd still get some pretty bad consequences. | Erayd (23) | ||
| 807623 | 2009-09-07 07:48:00 | It seems you have some experience with this... | ubergeek85 (131) | ||
| 807624 | 2009-09-07 07:49:00 | Not personally - I just have commonsense and some relevant knowledge. | Erayd (23) | ||
| 807625 | 2009-09-07 07:51:00 | I guess I'm in the same boat - just without the common sense... | ubergeek85 (131) | ||
| 807626 | 2009-09-07 07:51:00 | Plus there are a few subtle differences between a "car amp"and a UHF amp. Start with a clean slate - Use valves, then when you make a mistake, the coroner can make wise statements on why you shouldn't have done that. |
