Allison,
I just set the markers manually using eyesight. I don't know if they
are exactly on frequency or not. Tomorrow I'll let the SA do a peak
search and see what the actual frequencies are.
No RIT or PBT.
Since I'm looking at the output of the first mixer, the VFO is the only
frequency that applies.
I'm using a cheap MH5200 signal generator so I won't guarantee it's
accuracy.
I'll rerun the test tomorrow and see what comes up.

The 45mhz filter is rather narrow If memory serves its a 15khz (wide)
unit which is typical for common use (FM first IF work).? ?So for low
attenuation you need to be between 44.9925 to about 45.0075mhz.
The one marker is 44.9625mhz? which is 37k Khz off of center, I'd
expect a fair amount of attenuation there compared to inband.
Could your LO cal be off or the RIT/PBT be active?
