1. when  looking at the transmitted signal using a spectrum analyser,
the signal didn't seem as clean as we liked it.  We didn't  have
time (it was the day before X-mas!) to really  start counting the
dB's, but on 30, 12 and 10 m we saw  some signals around the main
signal. Is there any  chance we can get these bands 'cleaner' by
further  tweaking the filters?

Hi Jurgen,
 
Are you 100% sure that the spurii you are seeing are just not due to you  
overloading the input of the spectrum analyser?
 
This is a common cause of apparent excessive spurii!
 
Merry Christmas to all,
