Anytone Ares 2 with RFX95HD Install

That's sh1tty waveform for sure. Raising carrier won't help.

I am at a loss, maybe some kind of audio limiter on the mic socket? I will try some different microphones and see if I can make it any better.

I tried the Ares 2 with an RM Italy KL203-p amplifier just to compare. I could adjust the carrier up and down and it never pinched the carrier at any setting. It looks like the RFX is not a good match for the Ares 2, and I am not quite sure what is causing it. Maybe something to do with the input padding and gain compression? Or maybe that the RFX is a single transistor? Maybe I got a Bum RFX? If anyone tries this, and gets better results please let us know.

I think it is the padding on the input side, I think the guys at palomar mostly intended for it to go on cobra 29s with cliped limiters.

I have recently had 3 rfx kits blow the electrolytic capacitor in them shortly after powering up the unit the first time, after I change the cap no more problems. I run my bench at 14.8 because that is what many of the trucks provide to the radio and I like to tune at working voltage but that should not have blown the supposedly 16 volt cap/

I have an RFX95HD on my Galaxy 86v, works great, looks great on the scope in both AM and SSB. The Ares 2 is just different for some reason.

Did anyone ever figure out a proper npc for this board?

I think @Tim Chambers was working on a way to do it. Maybe he can give us an update.

Just randomly ran across this.

This one looks great on the scope, I am not sure what adjustments he made if any for the punching carrier. Someone suggested that I could reduce the modulation so that is something to try I guess. I made a comment on this video, and the reply suggests that he didn't have this problem. I have another RFX unit that I can try too.
