What U need is an old BT Engineer.
Rem as an apprentice using building out networks for customer line and doing end to end tests across various audio spectrums.
Was amazing what could be achieved across a bog standard line.
So ADSL Broadband techniques are perhaps not so new after all.
Just the technology has changed.?
 
Unfortunatly all the old boys who were equalizer network experts have mostly long served there duty and been retired off.
Or Died !.
However if you get stuck try Dave G3YXM who was a BBC Studio man. 
 
Don,t as me as I moved from apprenticeship onto Large Electronic exchanges and have only returned to transmision recently. 
If you get stuck maybe sort you out with some general theory u only need R & C,s.
 
Or if you can give me specific Source & Load impendaces maybe tell U how to flatten them.

Dave, 

You may be correct about equalizers but perhaps they are not commonly used
because we don't understand their value to us.

At present, I am struggling to obtain a decent recoding of my CQ in my
laptop using audacity. There are various weird noises in the background
(-30dB at a guess) which I would like to remove. I wonder if an outboard
equalizer would be a useful adjunct.

However, I do echo your question as to who selects products for review.

In general, in my view, Radcom is a much more worthwhile read (no pun
intended) since Giles took over as technical editor.

Neil, G3RIR

Outboard audio equalisers are not, in my experience, a widely-used
accessory. Some modern rigs have the functionality built-in to the
transmit DSP, should it be required. Perhaps there just isn't anyone out
there familiar enough or interested enough in such a product?

Which raises some questions. Who chooses which bits of kit get reviewed in
Radcom? Is this more a case of W2IHY trying to get some free publicity for
his piece of kit? If audio equalisers aren't commonly used, why are we
taking up valuable Radcom space reviewing one?
