great in depth Lots of good data and good practical tips. I built a pirate AM radio from a surplus tube signal generator and an audio amplifier and a long wire antenna - and after a couple of months the feds (uk version) busted me, that was 1968 and I was 14 hahaha, they didnt like me jamming hams with classical music and playing "pop" to my school friends
Best trick is to rig up a portable transmitter unit and locate it in a tree in a bush or park and use wifi band to transmit audio and remote control the transmitter use solar power and batteries. This way if the radio cops locate it, you will not get into trouble as there is no way of tracing the owner, also you can fit a camera so u can see. very good video keep it up.
Absolutely brilliant video just what I needed, built my own transmitter over lock down and been playing swapping bits and bobs trying to improve it performance slowly learning on the way how the coils and trimmer caps work etc it’s actually quite stable for a 2n3904 transistor but have no real way of checking stuff so this is a real eye opener for me how it’s done properly I did have a bash at a low pass filter seems to still function ok also 👍
Mediumwave AM can be fun and it's more challenging to get a signal out. Played around with it for a while using a 10W vco transmitter I made messing around experimentally
Just a warning thou, its only a matter of time before another licensed broadcaster complains when they discover a new station has poped up and is taking their audience away, the radio police come out with direction finder and give you a warning it not a fine. They can get the cops to kick in the door and confiscate all you're gear, they can take everything including all you're test gear, not just the transmitters, and issue you with a fine. So best to not run it for long periods at high power. This is the case in most states and countries.
Thank you. I'll continue making this type of video. I packed a lot into this one, so I'm still not sure what to get into in the next. If you have any suggestions, let me know.

another Q sir,can i assemble for example 1 15watts exciter fm transmitter with lcd display and control knobs, and fed it into an rf amplifier final with wattage of 100watts, is this ok to feed a 15watter exciter fm transmitter into a 100watts booster rf amplifier???
Avoid all the worry of FCC, play it safe in the Part-15 parameters which us hobby broadcasters are indeed allowed, then put your station's air sound on an Online stream. No need to operate at excessive power levels, thanks to the option of the stream.
Stuff the communications regulators and their transmitter licences. Both transmitter licences and receiver licences are rip-offs. If you can receive signals freely you should be able to transmit signals freely too.

Great video. I’m a newbie to all this and have got a 30watt pll transmitter from China. Is it possible to change whatever chip on the board that’s rated at 30watts to a 100watt chip and leave all other components as is?? Or am I just wishful thinking.
Not 100W, but someone did install a 70W RD70HVF1 and it worked for them. I tried the same thing on mine and it didn't work though, so it's kind of a gamble unless you know how to alter matching networks.

I have several antennas. I have dipole, 1/4 ground plane, dominator antenna, and log periodic. Depends on what you want. Are you outside or on the edge of the city? then use yagi or log periodic to aim at the city. Are you on mountains or flat land?

Help Spectraman I have the 100watt amplifier hooked up but I’m not getting the range atall. Comes through on the radio beside it but when I go out to car it’s not coming through?
Well, you did make sure your antenna was tuned and the SWR is low right? You really got to at least have an SWR meter like I said in the video. You made sure to drive the amplifier at the specified wattage? You said you have the 30W TX, right? If so, you obviously can't drive the amplifier with 30W, it will burn out. It probably needs only a couple watts. I'm not sure exactly. Please check the specs of the amp. You should probably also get a couple spare transistors for the amp just in case you burn one out by mistake.
Spectraman it’s the Chinese 30w pll transmitter. Have that at 1w which is the input for the amplifier. It’s the 100watt amplifier off Dutchrf with the heat sink. The swr would be on the transmitter but when I run it through the amplifier it doesn’t give a reading. The antenna and frequency have been what I’ve always used so need to tune that. Would it be something simple that I’ve overlooked. A bad solder or no earth?
@@darink5216 Your first mistake is buying a chinese transmitter - they are rubbish and often use a chip to generate the composite signal. These are not designed for real broadcast use, they're made for little mp3 transmitters and car FM transmitters that operate at microwatt level. Don't use them. Second, if you don't understand radio engineering, find someone who does. If you get it wrong and you are transmitting out of band signals you can end up in court and possibly even jail as you can be jamming things like aviation and not even know it. You need to understand what forward and reflected power is and how to measure it. You need test gear to do that.
