Was recently given an Elecraft T1 auto tuner kit and as now working in Belgium thought I'd make it up. First started in hotel room.
The portable 'homebrew' bench is perfectly adequate. Note I have brought a 12" square of PCB to build on.
Initial components going in.
Fitted the underside capacitor.
Fitted the sockets and headers.
Built up the control interface.
First fitting. Looks good so far however, visual check of all the components against the build list and couldn't work out why had extra FT37-43 torroid. Then remembered there is an errata...
No harm done, removed T2 and added the new T2 fitted easily.
Removed the PIC, added battery, checked the voltage through the 2N3906 when tune/pwr switch depressed and onto the regulator says 6V.
Added PIC and tested the power on, seems to be fine. Will test again once have working TX with me in Belgium.
