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

HBR602-LC

Another low cost, entry level, or easy to start transceiver from Hambuilder.
The fact, price still the main concern and consideration to start or to buy a HAM equipment.

* 25 watt power out
* SA602 mixer and demodulator
* 7 segment display
* si5351 synthesizer
* ABS plastic enclosure

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
*. 3.2/3.5 TFT LCD
*. 5.0 TFT LCD
*. 7.0 TFT LCD

note: some transceiver are on development, some are ready on our web-store/e-commerce

HBR4HFS, another 4 Band Series with 100Watt max power ouput

HBR4HFS, is another 4-bander’s series from Hambuilder. It is a medium size desktop transceiver with big enough power. We try to keep it low cost, simple to operate and simple to maintain. This item actually an upgraded power of HBR4HFN with previously providing maximum 50W power out by using 2x IRF530 as the final transistor. We can still adjust the power out to QRP level (below 10W) if required.

specification :

  • 2.2 Inch TFT Display
  • ATMega128 microcontroller
  • ADE-1 main mixer
  • Up to 100W power out at 80m and 40m, 90W at 30m, 35W at 20m
  • RX gain setting
  • TX gain setting (power out adjusting 0-100W)
  • Mic gain setting
  • Auto sensing Fan
  • 2 x IRFP150 final transistor
  • Morse generator, with ATTiny13 microcontroller

This item will be available to buy soon in our web-store, Tokopedia, Bukalapak and ebay.

RTC35, Radio Transceiver Controller with spectrum/waterfall

Sambil mempersiapkan produk-produk selanjutnya pilihan layar display selalu menjadi dilema. Pengalaman yang lalu menyebabkan beberapa produk akhirnya batal/ditunda karena LCD yang di kembangkan discontinue. Pasar componen di China memang menarik dan murah tapi tetap mesti berhati-hati karena bisa discontinue setiap saat. Membeli langsung ke pabrik mengharuskan dalam jumlah banyak dan harga diatas rata-rata diecommerce seperti aliexpress/ebay dan lainnya.

Perubahan jenis LCD menyebabkan firmware mesti diprogram ulang, yang kadang-kadang bisa cukup besar dan perlu library baru. Berikut adalah LCD TFT 3.5 Inch yang diharapkan menjadi display produk-produk Hambuilder ke depan. Tegangan kerja 3.3V dipilih karena akan dioperasikan oleh microcontroller STM32F407, atau ArmCortex M4 lainnya. Microcontroller akan di operasikan pada clock 168MHz.

Specification dan fitur-fitur yang di rencanakan:
*. 3.5 inch TFT display. 480×320 pixel
*. STM32F407XX microcontroller
*. Audio DSP
*. Morse DSP
*. CAT interface
*. USB/Bluetooth interface, wifi?
*. 14-24 matrix/keypad
*. switch rotary/optical rotary encoder
*. swr reading/swr analyzer built in
*. ATU driver built in
*. Digital potensiometer
*. Radio bus/pheriperal control
*. Independent band setting
*. … still continue

HBRMS1 Hambuilder Morse Sender

HBRMS1 di desain untuk melengkapi series morse trainer. Pengguna hanya perlu menyediakan keyboard PC biasa dengan koneksi PS-2 untuk dapat mengirimkan ketukan morse ke transceiver. Alat ini bisa juga di gunakan bila belum begitu yakin dengan akurasi ketukan tapi sudah ingin mencoba berkomunikas pada mode CW. Tujuan lebih jauh dari alat ini adalah untuk meningkatkan minat rekan-rekan mencoba mode CW dengan memudahkan atau mengeliminasi kendala-kendala operasi mode CW.

Spesifikasi:

  • ATMega8 Microcontroller
  • 16×2 LCD character
  • Rotary Encoder
  • 3-40WPM
  • Internal speaker tone
  • PS-2 Connector
  • Keyer Jack
