Anyone know how to do this HPC Mod in this video? Possible to do it to 497HPC, would it help any with the meter on 497HPC always reading high signal noise?
We did this to some Galaxy DX2547 radios with a 0.22uf capacitor. And a switch. Not sure where he connected his resistor to do what you see. He coulda been more forthcoming with the "how".

Looks like his box is a variable resistor set to the hi range with selected resistances in the kohm range.
And it looks like the leads go just south of that connector.
So maybe with a zoomed in picture of the components in that area to cross reference with the schematic (no board view available on cbtricks) it maybe could be figured out
A resistor sub box set to 33k leads me to suspect that it's meant to mislead. Might be legit, but the audio-circuit impedances in that kind of radio are typically lower than that.
Never could see the reason to tout this kind of mod without actually revealing what it is. Unless he's soliciting people to send him radio work.
