Thread: Own up, who's got a ham licence?

Since I moved here I can't reach the only local repeater (140Km away) no matter what antenna I try. (big hill in the path)

Who owns the top of the hill?

And HF is next to useless because the mains power is single wire earth return and gives me S9 power line noise. Yes I have tried grounding and low pass filtering.

Hi Terry

Read up on radio interferometry by phasing two or more antennas, you can get some surprising noise reduction results.

Don't know, but I do have a neighbor with a dozer, one dark night.....

Thanks a\Arthur, I will read that.
I am thinking of a dual antenna with one phase reversed for local noise cancelling.
Bit fed up with radio at the moment, I just want to turn it on and hear something. It's OK in the bush with the Codan, maybe I will just go bush permenantly.

Cheers,

If you get to phasing antenna's, grab the ARRL Antenna Handbook and read up, especially on the use of Smith Charts and another thing that's useful is knowing what the word CIVIL is used for in impedance matching, along with the formulae found in this article.

I received my new Advanced call sign today. I'm now VK2OTC.

So you don't need a prescription then.

Pretty tricky callsign that one. did you work at Doonside or Bringelly?

Only as a trainee tech back in the Sixties. I spent 37 years with OTC as a tech at satellite earth stations, submarine cable stations, head office, and manager of a couple of stations, etc.

Congrats on the call, Ron.

FYI, VK7OTC is the station run by my local club (REAST) on the Queens Domain in Hobart. It is the original site of the OTC station for the HF link to the Antarctic zone.
But it is also the site for the current Coast Radio Hobart. That body is headed up by a few amateurs.

Re the hill: Sounds like an opportunity to either set up your own repeater, or team up with others, even from the other side of the hill, to get a loose club together to share the cost.
There is always digital hf and below-the-noise stuff too. And NVIS. And Echo-link, And IRLP.
