OK, I will inse= rt an attenuator at the antenna socket (that=92s an easy move) & watch h= ow it performs. It is switched at 10dB steps so I will start at 10db of cour= se.

Alan,

When you wrote :-

Are you meaning sound card or receiver gain?

Hi Gary my only comment is that you may have too much gain in the system= . It
is sometimes better to have the noise further down nearer the axis..=

I am afraid there is a major problem with this kind of beacon, when=20= the
fading period is shorter than the sampling interval, so you dont really know=
what the path is doing. The only reliable points are the peaks, the trou= ghs
dont really mean anything without some very sophisticated analysis an= d
probably two spaced receivers. However it does give a snapshot of the bandwithout taking up too much bandwidth (this was what was required for 5MHz<= br>too). Despite all the data collected very little analysis has actually be=
done on the 5MHz data collected by this program. The one succesfull bit ofwork was that published in Radcom by Marcis Walden G0IJZ. I used it for so= me
time whilst Andy was testing the Poldhu beacon on 160m and also during= the
1st two months that ran. I was certainly surprised by the daytime path on160m from here. I have seen the data collected in Canada via Joe Craig VO1N= A
and it is difficult to see how to use it.

Still if you dont coll= ect the data you will never know!!

Alan G3NYK
