    This kit meets the basic requirements for a ham kit: 1) cheap 2) fun to build 3) might actually be useful one day. As mentioned by other reviewers, there are discrepancies in the documentation. I have tried to sort these out. A full set of my build instructions, in English, will shortly be available for download on the Central Alberta Amateur Radio Club website. Meanwhile I suggest: use a 25V minimum rated capacitor for C3; when adjusting gate bias temporarily insert a

    I have receive this kit on 05/02/ problem. there is some difference between the schemas and the printing on the board for example there is a capacity in // of resistor which in in the gate of irf530.All schemas I see have not !...Be careful in adjusting current of the irf530 (or buy several for spare ..HI...not expensive ) I have burn one and replace all by irfz24 without problems. I have adjusted Vgate at 3.5V (not exceed 4V... or use spare if is more for few mW I get 15W

    Der soeben erhaltene Bausatz inkludiert ein PCB V306 (20160621). Ich habe den Bausatz schon einmal erfolgreich aufgebaut (das war noch V305) und erwarte mir jetzt nichts anderes. Man beachte jedoch die hohe Eingangsempfindlichkeit (ca. 5 mW). Wenn man eine PA direkt mit einem typischen QRP-Transceiver (2 - 5 W) betreiben will, so gibt es andere, noch einfacher aufzubauende Kits. Die Verwendung eines nachgeschaltenen LPF ist in jedem Fall obligatorisch.

    It sure would be nice if Banggood would supply assembly/use instructions with their kits. It SHOULD be a simple task to supply those in 3 or 4 languages.

    Un semplice e divertente kit da costruire. E' necessaria un pò di pratica con i componenti SMD, ma con un buon saldatore a punta fine e buona pazienza si monta in due ore. Cercando bene on line si trovano le spiegazioni dettagliate per avvolgere i trasformatori e pure i riferimenti ad alcuni componenti che nel piano di montaggio non sono menzionati.
