Re: Uniden HR-2510 RX/TX, hi-fi mods

Hello Goldfinger:

Thank you again for your advice Sir

I will start to re-cap this old radio and in the process I will do the changes for HiFi TX & RX and install the socket for Direct Injection

Now it's time for hot iron to fill the room with flux fumes :twisted:


Best Regards

Re: Realistic TRC-465 TX & RX Capacitor Location

Hi Goldfinger: The capacitor in question for Direct Injection is C166 and connects to R185 Also I took some screenshots from the service manual for the capacitor locations that will help members in the future if they decide to do these modifications https://thumb.ibb.co/gYzLwv/TRC_465_Printed_Side_T...

Re: 142-2000 Direct Injection

Hello Goldfinger:

Once again thank you for your input in my quest for better audio on my transceiver :D

I been looking at brick wall limiters hardware and they are quite expensive

I guess I will have to keep a good stash of C945 and 2N3055 transistors in the meantime :shock:
