    I'm lost on how to preform this alignment operation on my 674B Hy-gain 5 using my Sencore SC-61 scope. I'll post a link here to a service manual for the Hy-Range Vlll, This is the exact same test i'm trying to perform on the Hy-gain 5. http://www.cbtricks.com/radios/hygain/hygain_8_3078/graphics/hygain_8_3078_pg4_pg22.pdf Now once you have this link up, Go to Page 19, Under the 16MHz Synthesizer circuit title, go to step 4, Here's what it say's under step 4, (Connect the oscilloscope between the secondary coil of L14 and ground) I do know where theses test point's are. (Adjust L13 and L14 for maximum amplitude) I do know where L13 and L14 are and i do have the correct alignment tools to adjust these coil's. My thing i need to know is what probe do i use and how to read this on my SC-61 scope. I'm limited on probes for this scope and using the one's i have i can't see any kind of increased amplitude reading on my scope beam readout. If your not familiar with the operation of this Sencore SC-61 scope, I have a pdf file of this scope here, The manual is labeled Sencore SC61 user ID12849. Thanks' for any help on this. 2WR267_Scott

    Any typical scope probe should work for this. It the scope is showing a wave form but no change in amplitude, may need to change the voltage settings on the scope to provide a taller waveform to see a small difference in amplitude. Don't know what you have tried, but I would set the volts/division switch and the variable control to almost fill the screen with the waveform. Since you are only looking for a peak change in amplitude the volts/div doesn't have to be calibrated.
