The rule is simple, If you send a log filled with 100 QSOs less than 5W and SAE(self addressed envelope). You will receive A4-letter sized printed award. This award is started 1992 by QRP Technical Group which developed FUJIYAMA transceiver dedicated to 18MHz band. Design of the award is impressive with Mt.Fuji drawing. Currently awarding program is maintained by JL1KRA. Use qrz.com to find his mailing address. Under this low sunspots condx, achieve 100 QSOs with QRP gear is your efforts.

Circuit House SSB Generator

There are several personal based QRP vendor activity in Japan. 'Circuit House' is one of them and they are providing good SSB transceiver components. CG-90A is popular SSB generator among Japanese builders. Though it need several modifications to adjust individual preference, 5700JPY is reasonable as SSB generator. Adding 6m or 2m transverter and QRP amplifier, You can configure a SSB mono-band transceiver. Chassis will be prepared by builders.

FCZ QRP 50MHz AM transmitter

One of the kit example with FCZ coils. Favorite of Japanese QRPers is 6m AM QRP. In dense population and novice license without code, 6m phone had been an entry point for beginners. Making SSB is rather difficult and MIZUHO already provided PICO MX series. Naturally many built AM transmitter for their practice. This is 10mW AM transmitter designed by JH1FCZ. Now the FCZ transferred kitting operation and this #009 transmitter kit is provided by Calibration and it cost 3500JPY.

FCZ coil

FCZ coils are popular among Japanese QRPers. Oversea builders quote TOKO mono-band coils often, but these are less common in market. FCZ Lab. prepares all ham band frequency coil in 3 different sizes (5,7,10mm). VXO and other special purpose coil are exist. Detailed specifications are open to public. These are benefit to reproduce homebrew unit by others. The only weakness of the FCZ coil is its price due to their high quality. Each coil cost only 270JPY. When the number of coil increased, they are dominant in your budget. There is no relation between FCZ lab.
