The Flea in Auckland broadcasts from Mt Victoria in Devonport. The

30mw microwave link in the 2.4Ghz range without success.
Has anybody else found a solution to this and if so how was it done/
I am after some advice and help. The Flea in Auckland broadcasts from Mt Victoria in Devonport. The studio is located 2.5km away in Bayswater. The challenge we...

2.4 will go a long way using gris pack aerials. You can get 200mW units. They will go many times further than 2.5km. Not really legal though Keith ... From:...

Microwave ovens use 2.4Ghz which is why it is a free spectrum area as commercial use is not reliable. ...
And I should add that frequency drift on microwave ovens is common. They don't have frequency locking like most transmitters. ... From: Ross Levis To:...
Many thanks for all of the coments. Ross, I agree about the interference on 2.4Ghz. Even with the directional Parabolic Aerial I was getting a lot of...
