Akizuki-Denshi's value Capacitance-meter

Akizuki-Denshi, now the famous Akihabara parts shop have Chinese cpacitance meter kit of only 1400-yen. This capacitance meter can measure both ceramic capacitor and dielectric capacitor. The small sized unit is attractive for weekend project by its bright 7-segment LED and automatic calibration. As a user, the ATMEL based kit distingushed degraded dielectric capacitors in my junk box, I am satisfied its performance.

ALINCO is selling DX-SR8 with QRP mode

ALINCO announced DX-SR8 100W transceiver with 5W QRP mode. Since, this transceiver is mainly target foreign market, shops in Akihabara does not have display. MSRP is quite cheaper than the other model, this is a quite attractive transceiver.

Kida-Denshi released 14MHz CW transceiver

Kida-Denshi released KEM-TRX14-LITE . The series of 7 and 10MHz transceiver now extended to 14MHz. The DDS based CW transcever is popular among Japanese builders.
Now DDS based multi band transceivers are famous by KX1 and HB-1A. But mono band DSW+ series from Small Wonder Labs are obsolate. This kind of simple monobanders are good choice.
Sanyo LA1600 is used for RX. This IC is announced discontinue in 2010, thus this is a good chance to obtain the kit. This kit is provided with Japanese manual. There is no relation between this company and QRP JAPAN
