I had it all up and running on receive working great for a week. I then got ahead of myself, over tiredd, and plunged a screwdriver in and messed with RV2&3. Still ok on receive.
Today I twiddled with Rv1, following something I had read earlier. Probably wrongly...grrrrrr... :-(
I then plug in a a cw key, for it to start this fault with the raduino flashing like a bordelo sign. I then notice the 4.7k snapped away from audio connector pin.
1. Stripped it all out of case
2. replaced 4.7k with new
rv2&1 are fully clockwise
raduino still flashing on and off when plugged into ubitx
Not flashing and all good when plugged into usb and pc
No idea what I have done!
What is the safest position to turn rv1,2,3 to ? My instinct is raduino regulator blown due to resistor malfunction? I am a complete newbie at this. please be patient...
