Firstly a big thanks to all that offered suggestions. They are appreciated.
I've spent a morning with Waecos technical people. They couldn't have been nicer or more co operative. They know of the problem, and are still working on it.
In the meantime, if you have a waeco (and they all use the same control module) and are having problems on various HF frequencies, grab a Schaffner FN2060 filter from Farnell. This filter doesn't "fix" the problem, but it certainly gets it to a level where you should be able to live with it (ie way down in the noise).
This was demonstrated (much to my surprise and waeco's delight ) this morning.

Just off topic a bit, but has anybody bought/used one of these newish expensive speakers (about $300-) that are supposed to cut back all/most background noise on the HF?
I don't know their exact name; any info would be appreciated.
Cheers

Roachie you mean DSP speakers ? Work well, just like a big filter (which is what they are basically). However, in practise they make the speech clearer rather than get rid of impulse type noise IMHO.

Roachie, as you know, DSP means Digital Speech Processing. If you know anyone with a Codan NGT radio, get them to give you a demo.

I haven't used them but reports I have heard from the Amateur Radio community say they are _excellent_ - and for A$300 or more they damn well should be! :)

As Footy is saying the NGT already has DSP fitted and the difference between it and a radio not fitted with DSP is rather broad.

Well... my Yaesu FT-857D has a DSP (Digital Signal Processing btw) but it's not very good - I consider it to be a posh tone control but it has it's moments on some weak HF stuff.

These speakers (I think Kenwood make one?) are a bit of a different kettle of wombats being _specifically_ designed to tidy up audio and, as I said, are reported to be very good - people with the 857D say they are worth buying - but I'm not going to, then again I don't use HF when mobile only when camped.
