Hi there Audioguru I was also suspicious to the TIP26 transistors i did a little search on the net, and it seems that they do exists. But i also think the whole PSU is a bad joke. ??? //Staigen

Hi Just burn all the excess power sounds awful to me, cant you use it for something good, making hydrogen or something. ??? //Staigen

Hi Have you tested the cirquit in the thread "sensitive parabolic microphone"? I belive it will work. //Staigen

?? //Staigen

Thanks both of you Did you checked up the radiostaton, and listen to the music? Its online! It have been running here since tuesday night! Night and day! ;D //Staigen

Hi Ante I have the "CMOS COOKBOOK" ! Can you scan it and convert it to PDF? If you can, i can send the book to you, so we all can have it! It is in a somewhat bad shape. Some loose leafs and so on. //Staigen

Hi there Tune the antenna to 460-470 Mhz instead of building an antenna tuner! :) I will send you my adress later. //Staigen

Hi What is gmrs / frs ?

Hi everybody, i'm feel that i am about 12 to 17 years old again! I was 60 years old in this week, and got a little present, just a tiny one, it was only an URL, but it make me feel like i'm back in the 60-ies or so. Its an URL to a radiostation that is playing the tunes i were listening in those days(Radio Luxembourg, Radio Nord and so on). Heres the URL: http://www.gamlagodingar.se/ //Staigen

Hi there installer2001, velcome to the forum LM386 cirquits usally works good, also TDA2002/TDA2003 cirquits! Many others are good too! A bad design can ruin the performace of an amp, make a good design! ;D ;D //Staigen

Whats the poll for? //Staigen

Hi there Ante First of all i will say thanks for all the books! Thank you Second, is it possible to request a book or two, namely "CMOS COOKBOOK" and "TTL COOKBOOK" written by Don Lancaster? These books will getting you to know the 4000-series and TTL-series of ic:s very well! //Staigen

Hi all of you This is the topic(thread) i was talking about in an another thread! Here you can upload some pics of your lab or workingbench for us other to look at! I gonna upload some as soon i can borrow a camera from somebody! :) :D ;D And by the way, my lab is a real mess, so dont be shy! //Staigen

Hehe Looks like mine then ;D ;D . Of course we all want to see it, and that goes for all others too, send up a few photos of your lab! Maybee we should start a new topic first, named " My Lab" or something! //Staigen

Hey Audoiguru A few photos from your electronics lab would be nice :) //Staigen

Hi I think 0.8 mm will be just fine, its only 10 turns //Staigen

Hi Audioguru is right, the RC-snubber is for stopping oscillating, not to reduce crossover! :) //Staigen

Hi Audioguru What do you think of making the coil airwound? //Staigen

Hehe Audoiguru, replying at the same time //Staigen

Hi I dont think you need the resistor, the coil can be airwound, its so small and have enough gauge to support itself! :) //Staigen

Hi Oops, i made a mistake! Yes Audioguru, the coil is not wound around R14, but connected in parallell with it! Then your coils are just right as they are, faizanbrohi! :) I agree with you here too, but i have seen 4.7 and 6.8 ohms also, but usally it is 10 ohms. I dont disagree here either, but it is up to each one wich project to build ;D //Staigen

I have seen a lot of these resistor/inductor combination, but they have all been wounded over the resistor and connected at the end of the resistor, the resistor itself usally is between 1 ohm and 10 ohm. The resistor lowers the Q of the coil! The coils you have done is just fine, maybee you should spread the windings a little. //Staigen

Hi The resistor shall also be connected to the coil and have the value of 1 ohm! Read the description, even if it is not very clear, the resistor and the coil is parallelled //Staigen

Hi One way of doing it is like this:

Hi again Madame No, increase the current drive instead, with a pair of transistors! :) //Staigen
