    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. http://www.caarc.ca/ Meanwhile I suggest: use a 25V minimum rated capacitor for C3; when adjusting gate bias temporarily insert a 10 ohm 5W resistor in place of L1; keep meter leads connected to the L1 pads during test away from the amplifier input [hint: high gain amplifier] replace the supplied potentiometers with 10 turn trim-pots; I have taken off one quality star for all the work I had to do to update the documentation.

    I have receive this kit on 05/02/2016..no 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 ..so !...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 HI..lol.) for few mW I get 15W at 14MHZ and 6W on 30Mhz and .... 1W at 50Mhz (surprise)... for 15mW input....25W at 14Mhz (with irfz24). This Kit is interesting for al ,they do not want to make the board, the board is good quality. the only one problem is when it is necessary to change irf when burned .So with patience no problems. thank's

    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.

    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.
