Default Re: British Heritage Television

A big apology is due for my tardy reply to irishtv's post. We well remember - and value - his reception reports of our first low-power tests all those years back.

This has proved a challenging (though always exciting) project, and inevitably has been something of a learning experience. The actual build of the equipment has been taking place at what was once the Radiocraft workshop at Sedgeberrow. For advisory back-up, we have been very fortunate to have help from someone with in-depth experience from working at one of the original high power BBC stations. This has proved crucial.

Only a few of us have been involved with this project - fitting it in when we can - and with the inevitable twists and turns along the way, it has taken years. Progress has been steady but there are still a few hurdles to overcome. The present position is as follows: Two new transmitters of substantial power - for vision and sound - have been developed from scratch and are now complete, along with their back-up safety systems. The transmitting aerial is in the midst of construction. To provide an excellent match over the proportionately broad bandwidth required for a good quality television-and-sound signal on Band I isn't straightforward. At the moment, our aerial isn't behaving quite as we want, so it is being re-built to incorporate some changes.

The last major challenge remaining concerns how best the construct the Vision-Sound Combiner. A Maxwell Ring arrangement is planned.

We are having to remain cagey about some details of the project, not because we enjoy keeping secrets - we are thrilled about what could be in store - but because for now the licensing discussions have to remain confidential. So information on the channel we shall be using, the power of our transmission, the programme material, and the location of our transmitting station cannot as yet be publicised. However we can say it will be in "the London Area".

Promising when we will be ready to go on the air will always be a vexed subject, because things never work out as one expects in the real world and certain factors are out of our hands. However we are hoping it will be 'months' rather than 'years'.

So please stay with us. When the time comes, full details of how to receive our transmissions will be available to reception reporters, upon registration, via our website: www.405-line.tv.


All the best,

Steve
