Hello >Anyway all being well early tomorrow morning I shall try and connect >the circuits I have together and mount them on something so they are >usable for experimentation. I managed to do this and had a play with the experimental circuit tonight. I will need to build an IF amp as I suspected but when I tuned the AOR3000 to a very very strong signal then I could see a 20mv p to p signal on the I & Q out lines of the RF2711. When I tuned to a strong 1200 baud data signal I could see some some nice sine waves on my o'scope when looking at the I & Q lines so at least I know the circuit is working. Now its time to order up some parts and design the IF amp and I & Q filtering and amplification circuit. Regards Ian
