Hi,

Could have been me you were referring to.

Several years ago, a friend built several audible meters for me.  They are a 
small bbox with two so239 sockets, for input and output.  There is a switch 
to select forward and reverse power.  One tunes for the highest tone when 
tuning transmitter or linear and lowest tone when in reflected mode.  You 
can leave the swr mode selected as 0 reflected results in no sound, useful if 
the aerial falls off.

The circuits were published in The radcom sevferal years ago.  I did offer to 
send them to anyone who was interested at the time but got no takers.

Not sure if the articles can be accessed from the RSGB webb site but I 
could probably send them to anyone interested.  I think I may have a pdf 
somewhere but would need to try and find it.
