I recently obtained a 330watt linear FM amp to use with my transmitter. I need to build a 28V psu to run at about 40A in order to power my amp. I have thought of using multiple 2n3055 transistors to regulate the output, but I am finding it hard to find a circuit for the PSU. Anyone any ideas (or ci...

Hi, we (myself and a few other people) are setting up a priate radio station some time in the not to distant future. I would like to hear about any experience you have with pirate radio whether good, bad or indifferent. The equipment used and the way people go about it. The main reason I want to fi...

Hi Sir Nigel, I'm not sure about PCS selling a 50w booster. I have looked at their web site in detail and have not come across one (the most powerful i have found on their site is 20w), but they do have schematics for a sort of universal booster that basically you put in the transistor of your choi...

Wack out a nice 40watt booster in both ready built and also kit form. I really do think that they might sell - if the price is right. People that want to transmit around their neighbourhood would only choose 1-2w, if anyone wants to transmit further than that they would probably want to go as far a...

Hi, I have a Veronica 5WTX (5watt FM Transmitter) tuned to 106.2MHz. For some reason every time I power it up the output frequency drifts just a tiny little bit and I have to adjust the VCO trimmer nearly every time. After about 5 minutes or so it seems to be stable. I have fitted a better heatsink...

Personally I like the slim jim design. I have built a few different antennas (i'm not fantastic at it, but can follow guides and make calculations etc and if you can do it, it is far cheaper than purchasing one). I have built a dipole, stacked dipole (this was a knightmare to tune and eventually I ...

Errrr, what's that got to do with antennas???? or is it antenni?????

:D :D :D :D I tuned my antenna (well checked it anyway and luckily it didn't need tuning at all!!) SWR at 1:1.1 :D :D :D Not bad I thought for a homebrew antenna. Well, got the ole ladders out, climbed the back of the house, dropped me pole, shoved me antenna on the top, stuck it back up in the air,...

:lol: Hummm, Strange people live in here....The force is weak within him....Anyway about sound solution. I have downloaded and having a play with it at the moment. If anyone has managed to sort a decent setup could you please e-mail to me - you can do this by going to your winamp directory (on your ...

DOH!!! I forgot to mention base 10 too!!!!! hehehe

Its all to do with 0's and 1's.... Its really boring stuff and I really can not be bothered to explain. But i will say this... if you are not familiar with base 2, base 7 or base 16 then dont even bother to try and grasp the concept of this as it will just confuse you. People in the early days had ...

:D Its not hard to tune an antenna, provided that you have a SWR meter (and not an old CB one - has to be the right frequency for the transmitter which i presure is 88-108MHz) and also provided that the antenna IS tunable. Some people make antennas and whilst in the construction they purposley const...

:D The other day I built an antenna from plans on the net. It's pretty wicked, I got about 2 miles with the antenna just sat on a tripod in my back garden (still untuned) :o running about 4 watts. I will let you know what it is like when I get it tuned and on the 30ft pole at the back of me house. :...
