Ok so I have just added a tap to the back of the chassis for my rtl sdr dongle as in this post??
After I soldered to R43 and C32 I tested the radio and noticed the receive had gone very attenuated! I unsoldered the cable and the receive became better but now when I transmit on 20m I am only getting 4w instead of the 8w I was getting. Also mic gain seems very low. I have to really shout to get anywhere near 2w now! I have just recently soldered a 47ohm resistor in parallel with r63 which made the audio so much better too...?

Any ideas what could have gone wrong? R43 and C32 both look fine...?

Thanks Carl.

Now the reception/audio is in and out too! Like a poor connection somewhere but I have searched for the last hour and can see no loose connections anywhere!?

I’m suspecting the 10ohm resistor R43. I’m not experienced at all with smd and perhaps I ruined it with my iron. I only have a 47ohm replacement. I will replace with that and see where I get. I can’t see it being the problem with the drop in power and mic audio level though...?

Carl.
