Vince:
It is a Chinese kit with the SMD already mounted. I would be very happy to receive the instructions! My email can be found on QRZ as W1LJ.
Since you have built one, mind if I ask a couple of questions?
1) Did you toss the Chinese toroid cores and buy new US-made ones? I've read that the Chinese core materials are NOT the same quality nor the same permeability as the USA specification ones.
2) Did the unit work straight away after you built it, or did you have to upgrade the firmware, or do any other modifications to make it function properly?
3) How much power have you put through it ? I'd like to use it on FT8 at a maximum of 400W output. The general rule is that an auto tuner can handle approx. 1/3rd of it's SSB/CW rating when used on FT8. The later ATU-1000s were supposedly upgraded to a 1.5 kW SSB/CW rating from the original EU2AV design, which used less ferrite in the inductors. Any comment on that?
Thanks for your help!?
