Measurement stuff
Voltage reference: Not precise UT61B, but I like it: 2.499: 5.003: 7.495: 9.999: More precise multimeter in Owon handheld oscilloscope: 2.499: 5.003:
Cheap waveform generator to test amps
This generator is based on two DAC904E, so it has acceptable parameters to test amateur HF amplifiers.
Stuff again :)
DeepVNA + something.
New stuff — LDMOS board + Miniware DT71
