same broadcast on all frequencies

[OregonGlenn]

Greetings all.

I have a Wouxun uv3d. I have a few repeater programmed in along with the police/fire/sheriff dept. During the day they seem to work fine. But early evenings I get the same broadcasts on all my freqs. and do not pick up fire/police etc. Am I doing something wrong here? I am new to Ham, studying for tech lic and new to Wouxun radio so figured I would start with operator error

Thanks folks for past-present & future help

Well, due to the increased height of the ionosphere at night, you were probably getting transmissions from further away where those frequencies are used for different things, namely that broadcast you were hearing. However, it is odd that you get it on ALL of your frequencies. You may want to take an extra look over your owners manual and see if there is anything you can do to fix that.

I have been hearing that wanky things happen at night (well no duh) with ham radios. It would seem to me that this would make them hard to use effectively. Is this true? I'm working on getting my license right now so I don't
have any real experience

Glen - find somebody nearby with a radio that can receive the frequency in question and see if he has the same problem.

NewGuy - "wanky" things are what makes amateur radio so much fun. Right now you can hear somebody three counties over. Ten minutes now you might hear Australia, or the Seychelles, or an expedition to the North Pole.

It all depends on what frequency you're using, among a host of other things...

[TheNewGuy]

Cool. Does the transmission ever become really short though like less than a couple of miles?

[K7KBN]

See the last line of my previous post...

[TheNewGuy]

Haha "it all depends on what frequency your using" wasn't super specific in my humble opinion especially as you were talking about long to super long range in the rest of your post but then too I'm a noob to all this and just assume there are certain transmission range parameters that are rarely deviated from which may be totally false and due to my general ignorance on the matter.

[K7KBN]

UHF/VHF are pretty short wavelengths, and as the frequency goes up, the wavelength goes down (important--this is why VHF/UHF antennas can be so small).

HF/MF involves much lower frequencies, meaning ____________ antennas. Fill in the blank based on the above. You can generally cover much greater distances on HF than VHF and above. Get a copy of a good radio book (ARRL has one). Do a little independent study.

[TheNewGuy]

Thanks. I actually am looking at that book right now, I'm happy you reccomend it.
