I am thinking of using a 28 Mhz to 1296 transverter as part of a Station re-build ( after poor result on VHD NFD!).
However I do not know the passband rejection of the above filter at 1268 Mhz. I have mailed Bert and he has replied the loss / rejection is 0.99 dB – I think he slightly misunderstood my question to him.
Has anybody measured the rejection at 1268 of one of his filters? His current web site does not appear to display the filter response and I am sure it used to.
