    Hi, I have a constant 1.0 error type 11 after replacing the OM345 IC1. That was a faulty one and before Ive got 1.0-1.4 with 12,14,15,17,19. Now the manual writes: error in 0-20mhz-sig.gen.mixed range. But have no idea how to check a mixed range... thanks !

    What is the GPS reference oscilator you are using?

    Hi, i have an early 2955 which belonged to one of the original design team. i bought it from his sister some years ago. I has a small fault i dont know if its something youve come across before.
    The variable knob 1/2 works, it responds to being turned but the result is the same which ever way it is turned. Thats to say right turn increases the attenuation and left turn also increases the attenuation?

    Would you like to have a go at repair of a 2965 that is not auto tuning like this one, also scope is not working. Dave M1FIF

    I’ve seen problems with the board to board links in between the metal cans, usually a good idea to pull them out and clean them, all the caps will need replacing anyway
