Kit is complete (takes about an hour to build) and working fine. I've upgraded the firmware to v3.2 and I'm using this in low power mode (10-15W). Two weeks delivery to UK.

snel na het bestellen in huis. goed verpakt. veel info op internet niet in engelse taal. bouw beschrijving via de mail ontvangen van de shop! alle onderdelen zijn aanwezig de smd onderdelen zitten al op de print. om de tuner ook te laten werken met een qrp vermogen kijk op mods atu_100 power lower than 5 W doe dit voor het solderen. gebruik een vna als meter voor de inductors.

To Togliatti delivery fast, saved literally for the evening instruction is in the Internet on the YouTube channels. The board was launched immediately, the main thing is not to confuse the power legs on the display otherwise the stabilizer can lock in the KZ. It is powered by 3.3 Volt on it stabilizer. SMD. In work for the transfer, I have not yet checked everything in the self-made body. Thank you

I did, I did. From 10 m to 80 m builds perfectly, 160 does not stretch. The set is full, the rings are good. Nutrition from the Crown is not suitable, it is necessary to eat fully. Recommend!

Delivery 12 days, collected for the evening, works, but the display with a power of more than 50 watts hangs. I think to shorten the train and add foil.
