Greetings all.
I have been watching this thread with a great deal of interest as I have a very early model AR-88LF sitting on my bench at the moment. I also have another AR-88LF waiting for restoration and an AR-88D that is fully restored but just needing alignment.
I do not have a sweep generator to do an effective IF alignment on my D model and I have been using it for communications with the IFs just peaked. It works well but lacks the famed audio bandwidth.
I was interested in John’s use of a sig gen set for FM with a suitable deviation to align the Ifs.
Hadn’t thought of that one! So simple!
I really need to go play in my workshop but need to get rid of other jobs first.
Thank you all for this thread and I wish you all the best John with your AR-88.

Robert.
