Well, what a night, just as I was finishing off the last bit of work on the radio, a new battery pack and fuses and connectors.

I decided, whilst I was listening to the radio, to switch over to the new battery. Now I did not use the off switch, just unplugged the Anderson from one battery and into the other.

POP, on it came, but the receive audio had changed. It had lost all of its punch, very empty and tinny, almost like i was running a 1khz filter or something.
I tried the TX and the power needle just straight to max and a high SWR too, that's with out speaking into the mic.

Strangely, it appears that CW TX is not effected... So?

So my initial thoughts are that I have jut blow the speaker? Nope, the TX is affected too...

Now I am thinking I have blown some of the front end mixer transistors... I know CW works different to SSB with regards to the mixers and such, ill look into that today and get a better understanding of what can be happening?

Radio still tunes and is on frequency, Just terrible thin RX audio and massive TX feedback/SWR.

Any thoughts?
