Where is it possible to get a ham radio capable of transmitting 1420 mhz?

[mkp04]

I am still a beginner within the astronomy community and astronomy itself, now i've had my first telescope for a year (looking to upgrade my equipment next year. Excluding telescope) and i want to begin with radio astronomy (and broadcasting). Now, i personally belive that humans have made contact with extra-terrestrials (call me crazy), and the government is keeping it a secret. So i want a radio transmitter and reciever capable of transmitting and recieving 1420 mhz frequency. I've been looking for one for a while now, without any luck. And if it's not possible to buy one that can instantly use 1420 mhz frequency, perhaps you could help me find one that could be modified to do so as i would like to be able to do it. PS It's probably a good idea to mention that i live in Denmark, though shipping most likely won't be a problem :D... Oh and is 1420 mhz still illegal to transmit? Okay it is, so just come with a radio transmitter and reciever suggestion, forget about 1420 mhz :D.

1420 MHz is a protected frequency http://www.setileague.org/editor/protect.htm but it is possible to construct a receiver http://www.setileague.org/articles/backyard.htm

Ah yes, i heard. But wouldn't it be possible to modify a radio that can use a frequency close to 1420 mhz?

Think your asking for trouble, it certainly will not be legal to transmit there.
The UK ham 23cms band is at 1240-1325, not sure about Denmark, you may have restrictions.

Why do you want to transmit at this frequency? This frequency is usually called the hydrogen line and reserved for listening radio astronomers. https://en.m.wikipedia.org/wiki/Hydrogen_line

In the danish frequency plan transmission on this frequency is forbidden. https://www.retsinformation.dk/Forms/R0710.aspx?id=190132#id8290c825-2945-4113-b191-d1301b41e96a

 

Therefore I woluld strongly advise against trying to repurpose a radio transmitter for use on this frequency.

Hmm, yes. I just want the possibility to be honest, as i'd really like to get abducted by Aliens lol.

Yes, perhaps i shouldn't, but i would still love the possibility. So please come with suggestions if you have any

[mkp04]

I still need a radio transmitter and reciever, so please come with suggestions

I don’t think any serious person with the knowledge here will help you with this task, as the only possible outcome is that your transmitter will disturb someone else’s radio astronomy Receiver. No one will listen and answer to your transmissions at that frqency band, just leave it alone.

My guess is that you are rather more likely to get abducted by the Danish National Telecommunication and IT Agency.

This website promote responsible astronomy and transmitting on the H-line is likely to cause problems for radio astronomers. Please don't do it.

Actually I should not have posted --- first rule of the internet, "Don't Feed the Troll".

Alright, i don't know how to modify one either so... Yeah, but i still need a radio

Seems like a good idea not to, but i still need a radio transmitter and reciever :D... Ps i don't know how to modify one either so, yeah . Forgot to mention that it does not need to be 1420 mhz....

You just will not find a transmitter at that frequency.

I know, but i still need a radio transmitter and reciever... It doesn't need to be 1420 mhz though

Happy to oblige. You are crazy.

Hello presumably not crazy person

So you joined SGL and in your first post asked us to help you do something illegal?

When that's pointed (which you clearly already know), you don't care.

Cheerio
