DAB radio interference

[XFool]

From memory (no I wasn't alive at the time) it transmitted on about 40MHz (or 40 Megacycles as it would have been)
What radio did you use?

It did transmit on 40 MHz, that is too high for usual domestic receivers with SW band. But it also transmitted near(?) the amateur 15 m band on 20 MHz. I must have picked it up on that (or imagined I did). I remember I verified it by - very patiently for a small boy - timing its return. I remember it now as being ~80 minutes. But it is given as actually having an orbital period of 96.2 mins.

I remember with other people 'seeing' it go overhead at night. It appeared a bit unsteady and wobbly to me. Now, of course, we know it was far too small to be be seen with the naked eye! What we actually saw was it's much larger final stage booster rocket, tumbling in the upper atmosphere following behind and below it.

I don't know the make now (would be one of those old traditional names). I have tried to look it up in the past. The front of the wooden case tapered from the base up to a narrow rounded top. So from one side it had a rounded triangular shape.

...Believe I've found it! An HMV 1122

I remember using that Record Player input.

My grandparents had a Decca radiogram with short wave. I can remember playing with it, and I loved all the exotic names on the tuning scale
Hilversum, Allouis? Saar?...erm Droitwich

Mind you, I notice from the service sheet that that HMV can't quite go down to 15 m on SW. So?... An overactive imagination?

Why do my kitchen lights affect my DAB reception?

If your halogen kitchen lights have been replaced for LED ones, these can potentially cause interference to DAB. Often when halogen lights are replaced the transformer is retained and this can be the cause of the problem. For further information see our interference caused by lighting help guide.
