Adding sockets for powercords Wolf 7
Will be easer to disassembly it to do some things.
Photo of some assembled stuff :)
Wolf 7 amplifier IMD 3
DAC driver output — intermodulations somewhere at the noise floor : 50W 37dbc = 43db PEP: 80W 31dbc = 37db PEP:
Different inductors in BPF

SWR was increasing and power was lowering. Was trying to figure out whats wrong… Finally…
Wolf 7″ RX circuit measurements.

No active cooling. Also there are no feedback circuits on both stages and untuned bias on the second.
