I use this method and in about >50 connects I have only had 2 connects at 31,200 - the rest being at >33.6k. All I can sort of go along with this, I played around with some equalisation of my line and I must admit to getting better results. I found that lowering the HF response slightly , 10pf and 10Kr across the slave pair from the btbox produced about 20% more successfull connects at 33k6 than before. Link statistis show an improvement from 38db snr to 43dbsnr. I eventualy ran out of patience and set s33=32 and I now get 99% success. ( thanks whoever posted that tip ) It was always the intention to fit a dedicated line , So till my new line is fitted , I will run like that. Its easy to blame everyone else, but as they say:- Common faults occur commonly. Now what was that about signature separators? -- Paul Higginson
