This is a Homebrew SSB Transceiver made from Indonesia -Bandung.
No specification or user manual but I will up date for more information near future. Easy to operate with less button and knob.

The price is affordable for newbies. It has very good audio quality on received with built-in AGC. During the test on transmit, I received a very good feed back with more to base audio quality.
There are few modification to enable the Transceiver having continuosly without any gap from 2.100 MHZ right up to 17.100 MHz. The Bandpass Filter (BPF) seem has limited ranges.

If those of you who have more information and wish to share with others, please e-mail me. 9m2da@marts.org.my and no spam please. Thank you.

My Homebrew Project

My Homebrew Project - BEACON


Made one for 9M2IDJ..
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

My Homebrew Project - PIC KEYER
Circuit and Source code are from IK0WBR Website
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

My Homebrew Project
PIC PROGRAMMING INTERFACE BOX
I started homebrewing this just to program PIC for the ARDF Controller/Oscillator.
Later it seem more usefull then I thought....I started experimenting with others PIC project.
The dc supply are direct from the pc, that mean you do not need any external supply to run this circuit.
I used WinPic software. This programmer are only for PIC16F series...... The number 8,7,4,3 and 5 are connected to DB9 socket to PC ComPort.
IC pin 4 = TXD
IC pin 5 = Vss GND
IC pin 12 = RTS
IC pin 13 = DTR
IC pin 14 = Vdd
There are few circuit which is almost the same such as JDMPIC.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

My Homebrew Project - Radio Interface Box
(For Puxing, Kenwood TK series and others)



The 5 Volt DC may be supplied via your PC.
The Original RIB using MAX 233, since I have few MAX 232 in my junkbox, so this is the results.
I have used this to program my Puxing, Weierwie and Kenwood TK series.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This is parts of my homebrew project. There are others homebrew project which I have done.
Repeater CWID using PIC16F84 which is been allocated at 9M4RMR and 9M4RSG repeater.
HF Antenna tunner for my ICOM IC-718 (2009),
Motorola RIB to program GP300, GP328, GP338,GP2100,GP328Plus and other...
PIXIE II QRP 40 meter CW Transceiver....Have not try it out...
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
My Kenwood TS440S have been back alived (2nd May 2010). Been silence since 2004 due to VCO problem. Left in Singapore for more then 2 years, headed to Japan and came back to Malaysia again with heartbreak.
Finally I send it to YB3 land with hope and lets it be a final journey...Thanks to the person which I only knows from friends which have make it back to alive....

Homebrew HF Broadband Mobile Antenna
1st December 2010 completed my Homebrew Mobile Antenna. 2nd December at 1340UTC on 20 meters managed to make a contact with 9M6TMT when I was on mobile.
3rd December have the picture and published in my blog.
These are my 4th HF broadband antenna which I have made.
I used my 5 feet fishing rod.
Inside the PVC are the Broadband Balun.
Transceiver ICOM IC-706 MK II with ATU.






















KGD("Kurz Geratener Dipol" ) SHORTY DIPOLE 
Looking for a simple short mono band dipole? There are several website explains how to make a very simple shortty dipole for those who have limited space.
Here you can go to the linked to few website which explains about the antenna.

Kod Etika

                   
KOD ETIKA YANG PERLU DIMILIKI OLEH WARGA HAM

BERTIMBANG RASA : Tidak akan menggunakan frekuensi (memancar) untuk menimbulkan rasa ketidakselesaan kepada orang lain dengan secara sengaja.

SETIA : Akan sentiasa mewujudkan sifat setiakawan, menyumbangkan khidmat bakti kepada rakan dan kelabnya.

PROGRESIF : Akan sentiasa memastikan stesennya (radas dan peralatan) dan juga kaedah pengendalian yang diguna pakai berada dalam keadaan sempurna dan efisyen.

MESRA : Bersedia untuk melakukan transmisi dalam kadar yang sesuai dengan keperluan rakan yang lain, menghulurkan nasihat dan panduan kepada rakan baru, membantu dan memberi kerjasama sesama warga ham; semua ini adalah merupakan semangat warga ham yang sebenar.

MANTAP DAN SEIMBANG : Radio hanyalah satu hobi. Seorang ham yang baik tidak akan membiarkan hobinya menjejaskan tanggungjawab terhadap kerjayanya, rumahtangganya, persekolahannya (bagi warga rakan muda), atau terhadap masyarakatnya. Ia juga harus sedar bahawa ilmu dan kepakarannya mahupun stesennya adalah sentiasa tersedia untuk dilibatkan ke arah khidmat masyarakat atau negaranya.
