13cm PA progress

Drilled and tapped the ally spreader plate and fixed the 13cm Spectrian PA to the spreader, the bolted it to the DB6NT watercooling plate.  Next job is to fix the power leads, input and output connectors and control connections.  Circulator needs plumbing in, then just pop the amp in between the transverter output and the antenna relay.


Completed PA assembly ready to solder the SMA sockets. This is a first fix, not slathered it in Arctic White thermal compound yet…


Initially I’ll use total loss cooling with a bag of water draining through the plate into a bucket.  Once all is well, I’ll plumb this in to the main fluid cooling system.
