Just finished the 2nd filter, these 0603 components are tricky and can fly long distances !!

Note to say that by setting different calibrated ranges for 1296 - 2592 and 3888 MHz on this VNA I was able to check the return loss at 1296 and tune for best dips at 2592 and 3888.  The point being that the VNA is listed as 3 GHz top frequency, mine appeared to go to 4 GHz.  Sure the readings might be inaccurate but if one is just tuning a filter for rejection, finding this extended range was a pleasant surprise.  I have not altered any of the firmware/software from purchase last Autumn, when I think i am right is saying John XDY, reported that there were several owners in the Ipswich area.  A remarkable unit for around £100 carriage paid.
