Randell,?

Running up on the increased inverse complexity of convenience, time to start monitoring power rails? Not being off the shelf plug ins, can¡¯t just add up published specs. You are having way too much fun.

I am going to use this lesson in our builders group, next month.

Added another accessory board to the rig. Built up the duinovox by KB9RLW. It works great for FT8 even with the bodged wiring for testing. The VOX is cheap and easy to build.?

The 4 boards visible are regulated power, relay board, VU2ESE AGC, and duinovox designed by KB9RLW. I'm now out of slots...but could build an expansion board pretty easily if needed.?

I do have an intermittent low power output problem. It started after another mod done and then undone. I haven't checked much, but I am not overly concerned about it? since the amp doesn't like much more than 1 watt drive anyway. It does have me curious, and at some point, I will give it some attention.?
