Dear David, Lowfers,

Most of my WOLF decoding has been done using a P133 with 16MB of RAM and 
Win95. The processing time required is roughly equal to the duration of the 
audio recording that is being processed. More recently, I have had a PII 
300 with 128MB of RAM and Win98- this does the job about twice as fast, but 
apart from that makes no difference to the result that I can detect. Most 
of the time, both machines are quite OK to use with the current off-line 
WOLF processing.

Apart from the very significant cost issue, I am wary of rushing off to buy 
new PCs at the drop of a hat - the maker's specs say nothing about the RF 
noise level a PC will produce, or peculiar software & hardware bugs, so 
there is always a risk of spending a lot of money on something that 
actually makes reception more difficult. One also has to consider the 
benefits to be achieved - if having the latest hot PC allows you to achieve 
0.03dB improvement in SNR, I would prefer to put up with waiting a while, 
whilst if there were major improvements to be obtained, I might think about it.

I am no computer expert; one day I might play with different operating 
systems, but at the moment all the radio software I use is either DOS or 
windows based, so introducing other operating systems would probably just 
render me totally confused!

Good luck with the WOLF development - will be interested to see the results.

Cheers, Jim Moritz
