Still problem with PA

I got home for the summer and unfortunatly the Power Amplifier still have problem.

I thought to fixed everything, I changed the TX/RX relay with a couple of Coax Spinner Relay, fixed the power supply seriously damaged after the shipment… but seem to have problem on the “input adapt”.

Whit 7 W of drive it loads over 700W so this means that with the 15/20 of drive I should have more than 1K easly… but, transmitting with the PA ON, the input swr goes crazy hight and the input variable capacitor doesnt work !

Need to be checked again 🙁
