Hi to everyone,

I am looking for an RF Converter (VHF Band I / III channels only).
I read, that the channels in Australia are a little bit different
as in Germany, same standard, but Band I is different.
I have only RF Converters for japanese (NTSC), russian
(OIRT), different old french and british standards.
In old Panasonic (National)/ around 1980, heavy push button VCRs they were commen.

Who can help?

Best regards from Germany,

MonsieurTelevision

I can recommend the Kingray MD100VS, an Australian-made VHF modulator. The output can be programmed for any Australian VHF channel, with mono or stereo sound, and the unit has a simple built-in test pattern. The price is about $200 Australian.

Hi Sue,

Thanks for the info, I keep this in mind, but it is not
really what I am looking for.
Otherwise I have to take it, if I cannot find something better.
The price - and maybe to complicated.
I cannot find a close-up picture.
I will check some other sources.

Best regards from Germany,

MonsieurTelevision

I tried, but I couldn't find anything cheaper! The low-cost modulators on the market here are all UHF only.

I did a quick check and the German VHF Band III frequencies are exactly the same as the Australian Band III ones so your modulators will be fine.

If you specifically want a VHF Band I (Australian) modulator you may find that you can retune a German one since some of the channels only differ by 2 MHz.

There are also a few circuits about on the internet for home made modulators. The low band VHF ones are fairly simple to build and tune.

If you want, I can also salvage an old VCR Band I modulator (Australian Ch 0 and 1) if needed and send it to you.

Hi TV-collector,

That`s a great offer. I am working on a big box which has
to cover all converters from any system.
I have old TVs from all systems!
What I don`t have are are the US and the australian converters.
What I have to construct (and that is not easy!!!!!!!!!)
are converters for the 2 old belgium standard which ended
in 1977 (625 lignes, positive video modulation, AM-sound
and 819 lignes, positive video modulation, AM-sound) and
european CCIR converters for Band III.
Please check if the RF converter works with 5,9 or 12 Volts DC.
The german Band I modulators a hard to find. I have only 2
and need them for channels 3 and 4.
Best regards from Germany!

I do have a converter. I'll need to test it first to make sure it works. I won't be able to that for a few days as I'm tied up with work and other things for the next week or two.

I have salvaged a converter and tested it this morning. If you email me we can discuss how to send it to you.

This is good news!!!!
Thats my email to get in contact with me:
Take my name in this forum (one word), add the assign sign (you have it in every email address - a letter which

Finaly set a dot or point like this one: "." and end with "de".
Simple!
