Am or fm transmitter

[singlepentode69]

With the ever decreasing radio signals now available on valve radios could anybody recommend an easy to build unit to make using cheapies components

There are numerous circuits on the internet and elsewhere for Pantry Transmitters if that is what you are alluding to.
There have been some notable circuits, mainly for AM of course, using valves or transistors.

AM would suit most of my collection as I only have two FM sets. So you have to decide what suits your needs best

Then what power o/p? For me there is little point in building a TX that doesnt cover the house. For this valve designs do this easier. I built a Mate by Peter Lankshear years ago and with 3 ft of wire chucked out the back it does (just about). Solid state TX are around but as I understand it need more fiddly aerial arrangements to give house coverage.

You mention "cheapie components" and that again depends on what you have: valves, chassis, transformers, trnasistors etc?

Don't forget that if you plan to leave a TX switched on 24/7 each watt of consumption will cost over £2 per year. Worth remembering when deciding to go valve or solid state.

There are now even cheap AM transmitter kits on Amazon.

The simplest is not much more than a transistor, 2 to 3V supply (or USB charger) and ceramic resonator. Even one less than 540KHz will be adequate on the 2nd harmonic. An old or cheap AM pocket radio can be easily modified or used for parts.

Not true.

So you are saying there are solid state designs where the aerial can be non critical? But which ones? Not the MiniMod thats for sure.
