Re: CW Trainers Ultra PicoKeyer Built.

Yes, the ultra pico keyer from hamgadgets is nice.
Make sure to set it up for iambic B operation.
When you adjust the sidetone down to around 700hz you'll find you need to use head phones or an external amplified speaker. The built in piezo just can't produce the lower frequencies.
Once you get your building skills up, the QRP Labs QCX includes a CW decode on transmit capability. It also can be set up for "practice" mode where it won't send out any RF. It can be an eye opener to see what the rig says you are sending. https://www.qrp-labs.com/qcx.html
