GREAT WORK DAVE! Can't say loud enough how stoked I am to see those channels in service!!! All that nice old gear working and sounds great on air too... Some times Newer is -- JUST NEWER! As soon as I saw the your cable roll... Aha it's LMR400 or Belden 997 (leaning more towards Belden) don't quote me on the model number. But yes TOP OF THE LINE for less loss (Capacitive Cable Loss) in the RG213 type coax cables. Loss at 2mhz would be more of the Ohmic Resistance type. Not so much the Cable Capacitance type. At 2mhz its more for the same reason you see speaker cables are really thick for Pro AV work. 5Mhz it would be starting. Any decent length you should still run LDF450 minimum. I still believe there is some more signal we can get out of you. I'm looing at the Doublet for use here. Cheers Buddy!!
Just discovered your station this evening when I recognised Kenny Everett. You've won me over. It's great to hear a local shorwave broadcast again. Looking forward to tuning in on some homemade valve regens.
Thanks Stu....great to see the current setup, quite impressed...I bought a Diamond WD330 to put up mainly to do listens to both frequency's haven't done that yet been a bit lazy. My Telefunkin 2525/3 arrived the other week, just waiting for a 7/16 to N adapter and high powers meter...LP-700 to arrive. I have an oil tin can load for tests.
@@vk3ase yes your are lucky, low noise site low light missions from nearby cites, just need a good scope with a Dome or a roll off roof oberservatory and you'll be set...
100w can travel a fair distance, I’ve received 100w MW stations from 2000km away. I would love to receive Shortwave Australia here in Finland! Somehow I think that won’t happen though 😆
Good to see all that older gear in use just proves it can be as good as if not better than new stuff. I will try to see if I can hear your station here in the UK I found I will but you never know areal us 60 good wire earth is a 4 foot copper pipe RX ft817
Certain times i think you might detect it. When the Australian Broadcasting Corp had the frequency's till 2017 and ran 50Kw both channels were often good strength into Nth America and Europe. Wwcr Nashvile 5k up from me on 4840 is often strong here and gives an annoying hetrodyne to some local listeners but they are on 100Kw so 30db stronger than me.
Basically nothing has gone wrong after 18 months of operation so far, the valve stuff is very robust but have got a few standby transmitters in case. Built some solid state transmitters but the saving in power use is not that much but will use them if the mains go down and can run them on DC from solar or batteries.
We have mains power, thankfully it is an RF quiet line but i have been collecting second hand solar panels and hope to set something up to offset the cost particularly when i get solidstate transmiters.
@@vk3ase Roger that, DJ. My property near Masset, BC off the NW coast of B.C. Canada has lots of big, tall, trees, but they are mostly spruce trees. Very dense branches, so anything launched tends to get caught in the thick web of branches/needles and won't come down. I've tried the slingshot method. Works sometimes. Mostly, it's the old fashioned way of a long ladder, then inching upwards towards the canopy. I've toyed with the idea of a quad copter as a possible solution, too! I'll have to check more seriously your 2 transmitters. I have heard 4835 here, but not 2310, but it's more for lack of trying, rather than not being possible. I used to love listening to the Northern Service ABC shower service on 120 meters. Always came in super well here.
You would have to compare similar program material received with the same signal strength and signal to noise ratio to make a valid comparison. They are mainly concerned with speech so could compress and clip it to an enormous extent and still obtain good clarity and many Db in increased perceived volume but would sound crap on other types of program material. I am constantly modulating to plus 125 percent and occasionally hitting zero on the negitive side so the mod is fairly heavy. Some of the music is of the nature that it will always sound soft no matter what you do to it unless it is pushed so far it sounds ridiculous, just the nature of acustics.
@@phoneticauit’s much easier to get speech compressed with a much higher average volume, versus music which relies on dynamic range to sound good. AM will always be a challenge for music If you listen to older recordings on vinyl from the 50s and the 60s, they were often mastered for AM broadcast and sound sonically different from mid 70s recordings mastered for FM radio. Lots of fun
I totally agree as it is a completely useless activity but so is spending your life looking at a screen as most people do today. At least i am using Australian allocations and the Chinese's may be less likely to take them over. Also i have learnt a lot about propagation and antennas etc. Searching for program material i have vastly increased my knowledge of music and other things so personally it is a plus and maybe just maybe i have given some one a bit pf pleasure.
Very nice and informative
GREAT WORK DAVE!

A JFET regen is good too. :)
How great
I was stoked to find someone still broadcasting from Aus on shortwave
Great work
Cheers
we so as well on 5.045
bayislands radio
10 over with 5.045 tonight 28/4 into Rugby NSW cheers
Really great to see you guys keeping OZ SWL interesting again
Where 5.045 located?
I discovered your station this evening. Listening to you on the mobile rig in the car.
Terrific work.
Thank you
Most of that kit is older than I am, but pretty cool to see it all in operation.
Strong S7+ on 2.310 now to QF44nh (Clear Range, NSW). Well done, Dave!!

Good night sky here also so i don't need to travel to see it.

If there is a radio heaven, this is it!
Great stuff Dave! Especially the class D transmitter...
Great stuff, both frequencies generally excellent here in Macedon ranges..
This is radio porn. Thank you thank you for this brilliant video! Greetings from Miami
NIce one mate!
getting ya in Townsville...keep up the awesome work

Top Work Dave on Short Wave Broadcasting

All to the good. Nice mitters.

hi there first time here i was trying to hear you on my shortwave radio on my little cc sky waves frim usa oklahoma i dont pick it up

nice looking forward to locking on
Nice! What is the most common part to fail inside that equipment? Looks like it'll last a life time.

Built some solid state transmitters but the saving in power use is not that much but will use them if the mains go down and can run them on DC from solar or batteries.
excellent work. How do you power up the station? Solar panels? Generator?
We have mains power, thankfully it is an RF quiet line but i have been collecting second hand solar panels and hope to set something up to offset the cost particularly when i get solidstate transmiters.
I would love if this radio station can be received in Indonesia
Im jelous bigtime lol...We have very little room for things at 5.045 like you do
Verry interesting👍. Albert the netherlands 🇳🇱📻
How did you get that 120 m dipole antenna up that high???
I have got very good with Archery.

Freqs? Time ( GMT)? Would love to hear here ( ret'd in FL). Karl
Need to run solid state class D or E maybe Jack up power and run on solar panels 52 volt battery supply
Why does VK2 ARNSW AM broadcast on 7146khz has better modulation depth than your shortwave ozztralia on 4835khz

Lots of fun
a lot of effort to go through just so a few DXers can pick it up. Whereas the general public ain't going to bother listening
