HBRCB-200 (CB AM 200 channel) design

Rekan-rekan yang ingin kembali aktif di band 11m (CB) hambuilder sedang menyiapkan sebuah transceiver CB dengan harga yang sangat terjangkau. Unit ini akan menggunakan synthesizer dengan teknologi Si5351 dengan kendali microcontroller. Versi ekonomis ini hanya support mode AM dengan display 7 Segment dan kotak dari bahan plastik ABS.

Specification:
*. 200 channel, on 5 group 40 channel
*. AM mode
*. 4-5W power out
*. Si5351 frequency synthesizer
*. 2 digit 7 segment
*. ATMega16 microcontroller
*. plastic enclosure (W:80mm x H:40mm x D:120mm)
*. condenser microphone

HSDR2 prototype

Salah satu transceiver yang sedang di kembangkan Hambuilder adalah HSDR2, ini adalah standalone SDR yang sudah lama direncanakan. Namun kendala-kendala pengadaan bahan-bahan dan proses pembuatan protoype membuat pengembangannya sering tersendat.

Berikut penampakannya, semoga bisa terus di kembangkan hingga ke tahap produksi.

rencana spesifikasi:
*. STM32F407 sebagai display controller
*. 3.5 Inch TFT LCD
*. ADE-1 sebagai mixer
*. AD620 (instrument amplifier OPAMP) as audio amp after mixer
*. STM32F103 as DSP audio processor
*. ATMega128 as I/O controller
*. 10-15 Watt output (RD16HHF)

rencana optional module:
*. ATU and 50watt back end module
*. 25.000mA Lithium battery back end module

Hambuilder transceiver family

According to our idealism, vision and mission the diagram below will show our transceiver product family. We must plan and considering many things. Our “micro team” must works 15 hours a day (ganbatte kudasai). Yes we made an error and mistake, bad purchase, bad communication and etc. Not perfect but try to improve in every way.

Hambuilder transceiver classification by power:
*. 0-25 Watt
*. 25-50 Watt
*. 50-100 Watt

Hambuilder transceiver classification by display:
*. 7Segment
*. 16×2 character LCD
*. 2.2 Inch TFT LCD
