Fixed a 440 repeater this weekend. Pulled a PA module out of line and rewired for low drive feed directly into the final PA. Discovered a blown up GAsFET and a poorly soldered shielded cable from a SAME alert weather station that were dragging in a paging system. Learned a lot...it's a new world for me.

I built this mic pre-amp and EQ kit about 18mos ago and never really felt it was doing much for me.

It bugged me and I had a Shure 522 kicking around and after someone's posting here about that very mic and the output level being on the low side, I decided to drag out that kit and really go over it again carefully, piece by piece. What did I find? One cap, reversed polarity. FIXED! Now that little sucker is working exactly as it should and my 522 has all the gain in the world...really nice pairing with that mic.

Not sure I posted it before, but my 55Ah battery is now all wired in place with the super power gate...I now have automatic shack battery backup power. Now I just need to make up some LED lights for the shack area and a relay to pop them on when the main power drops.
