FLIGHT
NZ97

ROUTE
AKL - KIX (Kansai Apt, Osaka)

POSREP TO
NAN (Nadi Airport, Fiji)

RIG
Degen 1103 SW RX

FREQUENCY - 5643

Aircraft was S2 and NAN radio was S4

I intercepted this with just the radios own telescopic antenna.

Good catch at time of the day frequencies start to open up around 3 pm sometimes 5643,8867,13261i stay up late to listen in the old days use to be up all night listenning to hf.

5643,8867,13261 are the HF freqs typically used here in the Eastern Parts of Australia.

Depending on the conditions, you may not only hear some aircraft reporting in with Australian ATC, however there are Nadi, San Fran, Auckland ATC that are present on these freqs as well

Am listening to Jetstar 205 talking to Auckland on 5643KHz at this very moment....

this seems to be a good info site http://www.monitoringtimes.com/html/mttopHF.html

Ta, dags.
I've bookmarked that one.

Yes me too. Thanks for that

[dags]

no problems guys after all that is why we have these forums to help each other out where we can!!

great site, after hooking up a long wire to my R-5000 I get S9 noise
Ahh well I showed my young fella, what SW stations sound like

[carmelof]

Active hf frequencies 5547,5574,5628,5634,5643,5667 signal around S7 noise level is around S1.

I can't set up anything permanent as yet but, is a log wire directional?

Is it better to have the wire in a north/south direction or east/west? If the HF signal is coming from the east as in the Pacific, which way round should the wire be, wire towards or wire across?

Hope this makes sense.

Actually, it depends on how long the Long Wire is. If it is less than a couple of wavelengths long, it is directional off the sides, like a dipole. However, if it is many multiples of wavelengths long, it is directional off the end.

hmm what is the ideal longwire antenna length? I can run 1 nth/sth or e/w

How far can HF travel? Particularly over water

Lets just say that Australian HF operators talk about the "Short Path to Europe" and the "Long Path to Europe".

One that works for you.

The longer the better, and as high as possible.
At least 8 metres is a good starting length.

my mrs would remove my u know what if I strung somthing 8 mtrs above the house!

I think I need to learn how to make that active loop

no he means the antenna should be at least 8m long
