Wenn es dann lief, dann war man stolz. Wenn ich das hier so sehe, dann bekomme ich wieder Lust mal was richtiges zu bauen. Ein Schaltplan dazu wäre nicht schlecht, ist aber nicht unbedingt nötig, man brauch nur genau aufpassen. ❤️

Ohwww.... Nostalgia !! :-) soooo nice to see! Thats how i started with this hobby about 47 years ago!! Only with al few small adaptions so you can transmit with it, and the WHOLE neighborhood HAS to listen my music over the entire FM band. :-) oeps. keep up te good work! and inspire people to build themself and get experience in the basics of this matery, in stead of buying ready-made products.!

@andrewferg8737 3 года назад

Great job. However, the purpose of using the copper board is to have a wide ground plane. It is best not to cut lines across the board as this disrupts the continuity of the ground plane. Cutting small circles or pads for each node works better and will help reduce the static.

@jyleehk 3 года назад

Agree. But his method is a very fast and convenient way to make prototype "PCB" without drilling holes or chemical etching. But of course, limited to only discrete small pin count components, eg. analog simple circuits

Is the board copper-clad on both sides ?🤔 ... a via from -vdd through to the back layer would work... I prefer the "islands" approach... small circular pads of pcb stuck on a sheet of copper-clad pcb for the ground plane... From the Emerald Isle 😎👍☘🍺

Is this really an FM receiver based on the Armstrong patents, or is it just an AM set using slope detection? With just two transistors the latter seems much more likely.

Your soldering would have been easier if you had cleaned your soldering iron regularly and the board before you started. Nice little circuit though.

@nikolaikim4649 3 года назад

That is what I call proper surface mounting 💪

@peterfitzpatrick7032 3 года назад

Thats actually called Manhatten construction.. though more usually small square "islands" of copper-clad board are superglued on to a fully copper-clad board, the islands being insulated from the negative - connected main board which acts as a ground plane and reduces stray inductance & capacitance . Look it up, some masterpieces out there... the soldering is very poor here, he needs more practice wetting the board properly before installing the components. But a good effort all-round... 🤗

Unfortunately, I'm an electronics noob with only a dangerous half knowledge. But I would like to use your schematic as a radio building project for our youngsters handicraft group. But not without understanding, how this works. I will try to comprehend, how it works in my own words, but please interrupt me, if this is complete and utter bullsh...! - You have set up an oscillator, that oscillates around an adjustable center frequency, e.g. 81MHz. - You couple in the RF signal from the antenna to bias this frequency to lower and upper frequencies. - The frequencies are mixed and as a result, you get 2 frequencies: 81MHz PLUS the received one, and 81MHz MINUS the received one. - 81MHz MINUS the received one is the recovered AF frequency. - The AF frequency is rectified through the diode of the transistor, to recover the original AF-Signal, as both half-waves together would wipe them out. - After that, this signal is going to a choke (10 micro henry) ? For filtering out the remaining RF? Is that the purpose of this thing? - Then you use a low pass filter, before going into the amplifier, to filter out all unwanted rests of any signals above the AF ?? Is that correct, or bullsh.... ? :-D Please help and correct me, to get a better understanding, on how this schematic works! I would relly appreciate it! :-)
