Hi I've got some questions about the broadcast power of a transmitter, can it be 100 watts on a unused frequency but close to 1.8mhz, would it be different for lower or higher frequency as well. Thanks

Everywhere on earth has some restrictions on broadcasting. There are Industrial Scientific and Medical bands
Other than that and CB etc. you need a license. Here in UK 1.81 to 2.00 MHz is the 160m amateur band, so with my license, I can transmit up to 50W, if you try without a license ... we will find you :)

Thanks sulaiman, it gives me a ballpark to work to. The prototype is about 200mW and when mouser gets the parts in July I should be able to get it built.

They will hunt you down if you don't comply with the regs. 100W is quite a bit - even though you think a channel is unused someone/something could be listening. The RSM website has links to all the relevant standards that apply in NZ. So there are no excuses. Call them if you need information - I'm sure they'd be happier to let you know what you can or cannot do, than to find you and haul your sorry arse through the courts.

Thanks 2spoons that is what I was looking for, 1.981mhz is general for maritime use, all over the country, but will spend some time in finding a good frequency of 😃

The frequency are getting a bit high, I would need 200*3pf and 3uH,not to mention any side effects, the transistor can handle it though, just a bit my level
