Its great that you are keeping this bit of history alive Don. Nice to see these majestic transmitters. There used to be an old MW transmitter at the museum in the city I enjoy your Saturday night broadcasts on 80m and 2m Great work!
Mighty fine, wonderful BC find! It's good that you've got a mission to save such BC rigs there. I've saved a few of my own. Sad that so few appreciate these fine classic rigs. Keep up the fine work. Hope to see more. 73, Bob, KD5MHQ (A bloke in the USA) ;-D
We had a BTM-2 which would still be running if it hadn't been upgraded with something more fuel efficient. Full remote control from studio. We did monthly checks after midnight closedown. Only problem I remember was a lightning hit which damaged the main HT Transformer. We had older AWA's elsewhere, and newer transmitters were STC. It was a lot easier to get parts and service when they were made just over the ditch.
And there is also a complete AM CQUAM STEREO exciter (with its monitor) in a rack there! That's a MOTOROLA 1300 CQUAM system, I think of the first generation of them! Keep that unit in tact, as it is great to have the AM STEREO capability available in your hands. Best regards AM 1098 CQUAM (Europe)
The RCA Ampliphase, transmitter was an excellent box, problem was many "engineers"? LOL! had no f-en clue how to tune them! I had three of these. The box next to it is a a Harris MW10! PDM transmitter! Circa 80's I had a few of them! Mw5, and MW50's! Used to convert them to Short-wave.Great boxes! Again same BS. not many people had a clue how to tune these as well...or understood the design....Dude is somewhat out in the clouds..Love the beginning of the video with the 4-1000a's .
Where is this site? I would love to come down and check out the site. It's fantastic that some one went into that effort to collect early pieces of equipment and looked after so younger generation can see what radio was like in the day.
The test of true Broadcast Tech was if you could tune an AWA TV exciter on the first try. They used blocking oscillator frequency dividers and it was so easy to tune them to the wrong sub-harmonic.
It was a true honor and pleasure to have met Don in person at the 2019 NAB convention in Las Vegas. I seem to have lost his email though, could someone point me in the right direction? His website seems to be offline.
BTM10's, BTM5's and 2's, TVH5's (two in parallel) for Band 3, TVB10's (again 2 in parallel) for Bands 1 & 2. I worked on them all. This was real broadcasting, the roar as the blowers started, the glow of the filaments and the crash as the HT contactors closed. Modern solid state transmitters are so boring. It's like comparing steam locos with their electric loco replacements.
I hate solid-state...it doesn't belong in high-power broadcast transmitters. Go ahead and put them in the exciter an IPA but keep them out of the PA...
Incredible machines, great to see you are preserving some excellent Australian made equipment.
Great stuff Don! That first transmitter looks like a modified RCA BTA-1R

Great work!
Hey great video nice to see these proper valve transmitters being saved shame I can't come over to see your museum cheers Dr G1TGM
Thanks for the vid, Don, in memory of a lot of vintage broadcast gear that did service to the public once upon a time ...

Love it - thank you for deciding to save some of this equipment.

Very interesting and enjoyable video, thanks Dave and Don.
Wow :) Always wondered what the old 5KA transmitter looked like.
Good on ya mate! I thought I had some "Big Iron" with a Gates BC-1T. Wow! You have one hell of a collection. Good luck and GodSpeed.....73 OM

Australia still makes some of the finest equipment in the world.

I'd love those in my shed!

Awesome stuff!!

What is the final tube in the BTM-2M?

Interesting Video...
Noticed you had shown my Local 3MA Mildura transmitter on your website, I wonder if they still have this unit!!

Is your web site still up, Don?
Has he had any of these transmitters on the air?
Did Harris have a plant in Australia?
Bad news to turn off plate voltage and shut down that first transmitter
"Fantastic"!!!!!
Muito bom!!!!!!!!!!!!!!
Hello Does don have any contact information?
what needs to be taken to the tip are new fangled EV with exploding batteries.
