These settings were posted by another of our group on a previous date and I have used them for some time and continue to use them with the latest Beta version firmware.

I use RF AGC and can find no reason for the AF AGC - perhaps I am missing something. There has been precious little discussion of this issue that I have seen. Some of our number have not been happy with the AGC currently in use and hanker back to an earlier release used on the original Orion.

They may be right? I must say the NR works on SSB for me. I also own a K3 which is another fine radio but even on their reflector some despair of the NR performance. I like both radios and both have advantages. We live in good times... 73 Doug, EI2CN.
