In Reply to: Analogue vs Digital posted by beto1 on July 16, 2006 at 13:43:04:
does anyone realise that, in the UK at least, 'analogue' FM is transmitted from studio to transmitter by relays using 13 bit digital conversion.So much for analgue over digital, although I have to agree FM does sound better.
Follow Ups:
In other words the BBC is using only 13-bit words at around 40khz ie 520kbps but this bitrate - in KBPS - is a LOT higher than the rate the BEEB ever proposed for R3 via DAB and is higher still now.No?
I was not suggesting that digital is bad per se, while your implication is that all digital is great / as if the word has this effect on your judgement.
The 13 bit digital stream used by the BEEB to distribute Analogue FM IS far better because it contains far more information - than DAB was ever going to - and more again than it does now, in the UK!
Mind your step!

Hi gopher,
I supose that here a big FM stations part transmiters will be done by digital equipment, but my main asking is for reception (tuner)house equipment.
Personally I prefer by far analog reproduction, when we can get a good sounding source, I mean, a first edition vinyl (first generation master tapes), maybe from europe or Japan, etc. Not all vinyl records sounds good, IMO, but when I can get some, wins by far to digital CD.
So, this topic become in a discussion about, when we have digital FM transmition, wich tuner will do the job better, digital or analog.
Best regards and thanks for your post.

P.S. For sure here are some analog transmitters too.
BetolMaybe you misunderstand. All FM transmitters are analogue by their very nature - they all transmit a frequency modulated analogue signal - but the source material (whether it is vinyl or CD) is first digitised by a 13 bit encoder before being sent to the transmitter and then decoded back into analogue for transmission. This is done to prevent losses if the transmitter is some distance away and not in perfect line-of-sight.
So the so called purity of FM includes two stages of digital conversion. Whatever is the reason for FM sounding better, it's not the method of transmission. My guess is it's limited HF bandwidth of FM and sharp birdie tone filtering at the treble end which limits the audibility of the digital arifacts you can hear so clearly on DAB.

Hi Gopher,
thanks for update me.
I'm looking for good, for the money, tuner to continue to hear some radio station that I like it.
I'm thinkin on some Sansui analogue (don't remeber wich model), there are also some digi/analog (TU-S5) and some digital (T-9) that are on my budget to this (US$100 or below). The key is to get hear, of course to avoid very huge shipping cost.
Best regards,
Beto
P.S. there is also a didital NAD (402) from '90's and an analog Telefunken (CT-1)
I'd suggest the one I have - a Denon TU-260L Mark 2. They are a few years old now but got excellent reviews at the time and sound great in my opinion. Sometimes however they can sound too good and show up the poor sound quality on some of the heavily compressed commercial stations over here. They can be had in discount stores in the UK for around £70 (around $120).They can also be heavily modified to make the sound even better.
Hi Gopher,
thanks for your advise, but I'm affraid that this model never have sold here because I can't get any info on the local pages.
I believe will be very cheap on some ebay auctions (35 pounds)but I'm trying to find here some one because I will like to avoid huge shipping cost.
Here are some Sansui, Marantz, Telefunken, etc, vintage tuners and some from Technics, Yamaha, Kenwood,NAD, etc from the 90's.
Kind regards,
Beto
