Bendix/King KX 99

I got the unit from local guys selling it for cheap price, but without battery, only empty battery case. But it still worth something.
Once power up the unit, it could receive and transmit (opps) Not sure if it still transmitting 1.5Watts, the most full power it can go. Will try to borrow Diamond SX200 to test it out soon.
After sometimes, it couldn't speak out. Nothing from speaker. Swicth off and on again...then it back yo normal. Something wrong! I tear up the unit, and managed to get to the problem.
It's a dry joint on yellow capacitor, valued 100mF 16V ELNA, I desolder it, check if the trace is problem. Trace look fine, test the capacitor, also fine. Solder the capacitor back, power up and works as expected!
Reassemble the unit...start to enjoy airband without interruption although I also own IC 2200H in the shack.

Opentracker1+ with Bluetooth

The idea of using bluetooth come around year back, during that time I've not enough resource to get into, especially to get a bluetooh module. Lukily my friend VX, 9W2VXP managed to get it from China for much cheaper price. The first project is to make CAT for Yaesu FT-8x7 series, after trying few type, at last we managed to find the proper one.

The CAT bluetooth project is success, we manage to sold few unit to local hams due to their interest, and none of them having problem using it over android smartphones. It's really quite fun experiment with this.
To bring it more fun, I did find it also manage to pair with few TNC that have capabilities to do KISS mode. My first attemp is using it on Byonics Tinytrak4, the TT4 currently running as TNC for my Igate 24/7, as also RMS Server on Packet Mode.As TT4 capable to splice to dual port using single radio, I would like to fully utilize it.

I disconnect the Port B (RMS use) and hook it to TTL-232 level convertor and to bluetooth module, run Aprsdroid, set up the bluetooth tnc, fill in few parameters, got it running. At first I'm running on non OSM version of aprsdroid, after trying the OSM version, it much more suite me, because the smart phone that I'm using for expement is not suscribe to data plan. It may run without data plan, as pre loaded map also embedd into it.

The second attemp is to us Opentracker1+, and nothing change to my previous setup, I just need to load the OT1+ with 9600 KISS firmware, and everything works as expected.Today I manage to get it run on the road, travelling 30km+ and I may need to adjust the smart beacon menu.

It's another cheap method instead of buying TMD710 or FTM400, hehe

Here is the track for today,and lower pictures during my test in the house.

9W2NHE-3 Shutdown

On January 14 2014, 9W2NHE-3 one of the earlier digipeater in Kuala Lumpur or in Malaysia has been shutdown.
This digipeater was installed on October 24 2009 by 9W2LL 9W2TLB 9W2WDH 9M2ADI 9W2CIA 9W2BDE and the late 9W2NHE.
Norhisam 9W2NHE involved in motorcycle accident few years back and pass away. From that day we have try to find a way to get in bring the equipment down, as the building also had been sold to new owner.
Just on the right day, 9M2PRO text me if I'm available to assist him and bring down the equipment, and I say yes. We meet up around 1430hours and get up and disassemble everything.
9W2HH Hamdan also assist us on that day. Within 30 minutes everything settled.
