If we've always had that, why is the car boot open? You aren't smuggling in another old TV are you...?

If you want to see what tat really looks like, take the back of a Robert's Revival if you dare to peep inside. When my son's went up in smoke, all for the want of a penny diode to prevent polarity reversal damage, I nearly had to reach for the bucket, considering that at the time, the Revival cost about £150. Puny little speaker, ill fitting MDF cabinet parts, cheapo SRBP PCB, using two chips for the 'radio' , one for the audio, and not much else. The volume control is mounted on a small SRBP panel with perforated holes at the edge where the panels were snapped apart during production.
By comparison, the Bush TR82/97 is a work of art, but let's face it, though the original series of the TR82 family was and is much loved, it too had its shortcomings - 'BUSH' logo made of plastic made to look like chromed metal, which loses its 'chrome', a dial that 'mists up' and back panels which were fragile at the edges and often wouldn't come off so were prised off at the edges, with inevitable damage to the back panel. But then they were never meant to last as long as they have done, and are very easy sets to work on, albeit some joker at Bush decided to hide the detector diode inside an IF can! I recall when they came out, that it was quite a bold move as by then, the trend had been to smaller and smaller pocket sized (sometimes vest pocket sized) radios. However, there was a backlash against the 'tinny' sound of such radios, with their puny speakers, and the TR82C was the size and wight of of typical 4-valve portables which had by then gone out of fashion and off the market - Lady Margaret etc. The TR82C, with it's large speaker and tone control, was a welcome antidote to 'pocket radios. Unlike old Roberts radio, (EG R200 etc), the TR82C does have a decent handle - not a flimsy leather strap which rots due to perspiration from palms of hands, or knob brights which fall off and get lost. Maybe it's my old ears, but I've got a TR82/97, and although I don't use it, it sounds quite respectable to me on all bands. But then my Pure Evoke DAB radio sounds fine to me too, despite many people denigrating DAB. Yes, it must be me, I'm sure!

As you are aware David, I've got the full 15 model series as regards the MB60/TR82/VTR103 portables, and the TR82/97 isn't a patch on any of them. But then again it was never mean't to be, it is a modern reproduction copy after all. I also have a TR82DAB, which is basically a TR82/97 with a DAB board built in as well, the entire top panel having been turned over to this with a blue LCD display and numerous push buttons. I only use the set for DAB, but I can honestly say it is really quite good! Regards

Try looking inside the coil that does the ISM function on a Hacker Sovereign II - there's several resistors, capacitors and a diode in there! And, DAB is OK really - it's how the broadcasters use it that determines the sound quality, not the medium. For general listening, I'd rather have some of the subtle MPEG artefacts (if you can actually hear them) than the noise and multipath distortion of FM. All the best, Mark

portable dab radios are let down on two fronts.
1.very low power out put.(to do with power consumtion?) 2. very little speakers . I dont understand why some one cant make on with say 2 watts rms and 1 mono 4" speaker. i have a full size hi set witch i use to listen to radio 4xtra and other things not on fm. but for music on radio 3 clasic and even radio 2 my leak trough line even with cheap decoder sounds far better. Also why do local radio stations even bbc ones not broadcast on dab? why is power consumtion still so high on dab? rob t
if its made by hand it can be repaired by hand

It must be a regional thing, Rob, as both BBC Radio Sheffield and the commercial Hallam FM are on DAB here.

I gave my DAB radio to my father in law, to be honest the reception where I live is rubbish, even though as the crow flies, the Sutton Coldfield mast is probably 15 miles away, most stations were a bubbling mess.
I mainly use a bush WiFi radio for my listening, but again, most of the stations I listen to are internet only, (RNI, Big L, Atlantic oldies etc) and BBC radio 4 extra for the old comedy shows. But must admit, I find it a pity that DRM (Digital Radio Mondiale) has not taken off, I think it would be a good way of utilizing the SW band http://www.drm.org/index http://www.drm.org/what_can_i_hear

However I was always under the impression that fitting the detector diode inside the I.F. can was regarded as a good design feature, since it restricts harmonics produced by the rectification action of the diode from interfering with other bits of the circuitry that are R.F. sensitive and thus subject to interference.
