Do stations still broadcast on Shortwave 1,80030,000 KHz?
To my dismay :sad: I find none of my modern audio equipment with tuner are giving me AM stations above 1600 KHz (Sony, Philips, Yamaha)
Out of the blue felt like listening to the Hindi transmission of Sri Lanka Broadcasting Corporation on 25m band (11800kHz)
I tried reviving my old Murphy Classic Model No 1405 TM. It is still powering on after around 30 years of storage. But not catching any signal. I did some troubleshooting. The inbuilt amplifier works because if I touch the middle terminal of the volume control, I get the typical 50 Hz hum.
In this radio, one changes the channel by sliding the dial (instead of a tuning knob). It can be powered by mains, battery or external battery eliminator.
Does anyone know a good guy in Chennai who can repair the tuner section? This radio is a beautiful piece of art. This radio even has a regulated power supply inside using a zener diode and a small power transistor. The power supply is a center tap transfomer and uses two green coloured BY127 diodes for rectification. Would want to repair this radio.
Are there any other options? Does anyone make these kind of radios?
