Howdy. Just had a HF installed by local Auto Elec (not the supplier of the radio). While not the most ideal arrangement, the testing etc has been left to me. Unfortunately there were no local suppliers of HF and so I decided to go down the path of sourcing the radio and having it fitted locally.
Have been fiddling over the last few days - mainly in my driveway in Moe (Victoria) and one drive a km or so out of town. In summary -
1. I can hear the Marine Weather out of Charliville on 8176.00kHz and less clearly on their neighbouring frequencies. I have also been able to pick up some relatively faint transmissions of ABC in the NT, and VOLMET (
Sydney) aviation weather.
2. I cannot hear traffic on any of the VKS channels. I have been checking skeds from various bases on various frequencies - morning and night. Some extremely faint traffic during sked times - but mostly fuzz. On one occassion outside of sked time I could hear one part of a two way conversation clearly - which gave me a bit more sense of what a clear transmission would sound like. I suspect it was from a base as the operator was giving
feedback on signal strength from the other party (who I couldn't hear).
3. I have used selcall to the
beacon number of the
Newcastle base and heard the revertative tones - but this has been a little hit and miss (ie. not repeatable). I have not been able to achieve this from other bases.
I guess my questions is, what should I expect? Should I be able to hear traffic during skeds from my driveway? Do I have to get out of town? If so how far?
If it doesnt sound like things are working as they should, is there anyone around in the
Latrobe Valley who can give me a demo so I know what to expect?

Hi Tim
You should be able to hear sked stations on bit of wire (20ft or so) just plugged into your radio instead of the autotune - when they are operating- and and increase in noise when they are not and your wire is plugged in.
You should be able to then put in the autotune and they should be stronger, which will be an indication that your antenna is working at least in part. Then its on to TX.
A catch is that even at sked times there are often many times that there is no transmissions. I listen quite a lot on a handheld sw radio in
melbourne city , and noise is always present , but stations are readable (mainly base operator).
P.S. What have you done with Moe High School - went there in sixtes and when went back last year it was gone !

The thing that I don't understand is my ability to hear the Marine Weather, and various other bits and pieces, and my ability to TX selcalls to various bases and get revertive tones, but yet nothing on VKS at sked times?

Marine weather is much more high power. If you get revertive then you should be able to hear any voice transmissions at that time. Yes, in many cases you should be able to hear both sides of the conversation during skeds, depending upon conditions. In many cases it will be as plain as day, in others it will be scratchy.

Latrobe City Council developed the site as an estate. A terrible design - you cant get out the other side! One way in, one way out. At least they left some
open space.

OK, an update.
Firstly, thanks to a few EO members, I'll be doing a
test run involving mobile setups in
Adelaide and
Sydney in 45 mins. Peoples willingness to share knowledge, experience and give their time is just fantastic. I've also had an offer from someone local to swing by and give a second opinion.
I sat in the backyard this afternoon and was able to hear most of the sked from charters towers and part of the sked from
alice springs. I managed to get a radio
check in to
Alice Springs, but I think I cut accross some other traffic that I couldn't hear! Oops. Not the time to speak with the operator about signal strength etc. The strongest signal seemed to come from someone near
Mudgee.
Others don't seem to be having difficulty making out what the operator is saying, and they don't seem to report too much difficulty in hearing the mobiles. Makes me wonder whether my Receiveing could be improved somehow.
Maybe i'd better just get a hearing aid. Tim

Test failed. No selcalls, no voice calls to either
Adelaide or
Sydney, on either VKS ch 1 or 2.
Where to start with trouble shooting.

Tim your time stamp said 1952 + 45 mins = aprox 2040 EST. I was on in
Perth till 1835 WST or 2035 so you just missed all the skeds by 15 mins on Ch2 if you used it. I switched from Ch2 to Ch1 @ 1825WST. Its also getting very long that time of night, I hear aisa very
well.

G'day Rox. We set the time as 2035 so as to not interfere with the VKS skeds. I was scanning Ch 1 and Ch 2 for a good 20 mins before that also and certainly couldn't hear anything out of
Perth from the middle of the Moe racetrack.
