collins: R-390A/URR The Y2K Manual;
Having to pull the RF Deck to clean the bandchange switch wafers (a chore that I seem to have to do every two tyears or so) reminded me of the need to re download the Y2K manual http://www.hausernet.com/r390a/ . This is not the original technical manual mentioned in previous posts.
Thanks to the authors for putting this together. Apologies to forum members who may have this revised manual with some colour pictures, but it may be of interest to new owners.
