Meeting with OM Rasid 9M2RS at Kuala Lumpur

During my visit to Kuala Lumpur, Malaysia I met Om Rashid 9M2RS on 30th March, 2017. He was kind enough to come to the hotel where I stayed. We had very nice Eyeball discussing about his Indian Ham friends and in general about the Ham activities, exams, grades in Malaysia. Then he took me to the Kuala Lumpur Electronics market to get an idea. I am very grateful to him for all his kindness and help. It was a memorable Eyeball.

DIGITAL SWR CUM POWER METER

The digital SWR / Power meter is capable of displaying the SWR, peak envelop power (P.E.P) and instantaneous power values. The SWR and P.E.P power values are displayed in the first row of the LCD and the Instantaneous power is shown in the form of a bar graph in the second line of the double line LCD. The power meter can measure power levels up to 150 watts. The readings are quite accurate in the entire HF band up to 30 Mhz.

The unit operates on 12 volts external d.c power which can be fed by a 500 ma adaptor. The unit has protection against wrong polarity. The “TX” and “Ant” connections are made through SO 239 connectors provided at the rear side of the unit. The unit can be kept permanently connected and during transmission the SWR and power values are directly displayed. The unit requires no other adjustment. The photos shows the front and rear side of the unit.

LC METER

The “L” ( Inductance) and “C” ( Capacitance) Meter has an accuracy of 1% of the reading. The LC meter has a LCD to display the values of L or C with units like pf/nf or uh/ mh. The LC meter has a push button switch on the left side of the unit for selection of “L” or “C” measuring mode. There is a slide switch on the left side for switching the power on. The LC meter works on 9 volts internal battery. On the right side of the unit a socket is provided for external 9 volts power supply. With the external power, the back lit of the LCD glows. To save battery power, back lit will be turned off when the external power is disconnected and the unit continues to work with internal battery. The meter has an automatic standardisation feature. It is provided with Zero push button and for Inductance measurement a terminal shorting push button. The unit has a spring loaded socket for connecting the component to be tested. The photo show the front view of the LC meter.
