[R-390] AGC

[Merle Crowley]

Hello all..

While I had my 390A RF deck torn down this last week,I happened to read =
an article in an old CQ magazine that was telling about a neat way to =
improve the AGC action with out murdering the radio. Rather than making =
any changes to the RF deck I did make an easy change in the cable jack =
going to the RF deck which can be returned to normal very easy. Anyway I =
was testing this change out this afternoon, I do think it gives you much =
better control with the RF Gain Control. What the change consists of is =
grounding the 220 ohm cathode resistor from the 6DC6, thereby, when you =
are backing off the RF Gain Control you do not change the gain of the RF =
Amp. I played with this setup by listening to many signals and switching =
back and forth between the stock way and the revised way, like I said, =
preliminary tests lead me to believe I like the new way best.

Wonder if anyone has tried this and if so I would like to see what your =
opinions are on the subject.

Thanks for the bandwidth !

Merle
