[Milsurplus] ARR-15 selectivity

[Hubert Miller]

Has anyone a good link to the article describing how to tighten up the ARR-15 selectivity ? It had to do with decreasing the IF coupling caps.
I mean RETAINING the variable IF, NOT using a 500 kHz mech filter.
NOT the silly audio filter thing mentioned in some silly conversion article.
I am also wondering how well this idea would work out on the ARC-2.
