Question about Sangean HDR-1 Radio

1 Answer

It won't turn on anymore. My HDR-1 worked a few days, and then refused to come on. Neither the remote nor the power knob can bring it to life. I replaced the battery in the remote control, but it didn't help. Now what?

This particular model is known to be prone to static electricity.
You may try first to reset the radio by taking all the power sources off, including AC power, the D batteries, and the AA batteries. Leave it without any power for a day (at least 12 hours, but 24 hours would be better).
This would cause a processor reset. Plug the power sources after 24 hours and check it out.
If that doesn't bring it back to life, then you may have to open it and do some more involved work (if you are handy with soldering and replacing electronic parts).
Usually the sensitive part that gets fried by static electricity and causes your issue is the Q1 transistor, which is a field effect transistor (FET).
Most likely your FET Q1 is a Sony product which maybe labeled as 2SK152. It's out of production, but you may find it at some major electronics outlets, such as Mouser Electronics.
There should be some equivalent FET out somewhere (RadioShack, perhaps?), if this particular one is not found.
Replacing the FET should be an easy job after you have opened the cover (5 screws), and unscrewed the board.
Just be careful not to cause further damage by static electricity from your body (wear a grounded static discharge strap), and be very careful handling the board.
Best of luck, and hopefully you will comment here if this has helped you resolve this issue.

Radio won't turn on all the time. It works fine when it does. I cleaned the on off and it still does this. HELP

Try spraying electrical contact cleaner down the shaft of the on / off / volume control (after removing the knob itself) with the radio unplugged. Operate the knob if possible to "work" the cleaner into the mechanism - or gain access to the control from the back (inside) of the radio. These types of controls have an open snap action switch that is often piggbacked on the mechanism that may be visible or behind a tin protective cover. You may need to dismantle the cover to effectively flood the switch with cleaner. Read the label of the contact cleaner before using - as some may attack plastics, etc.

Good luck!

Radio working just fine But no sound coming from speakers

if the radio still has power the audio amplifier ic in your radio has failed.
take your radio to an electronics repair shop or, replace the radio; this not something you can fix unless you know how to use an oscilloscope.

Get a lot of static when try and turn volume down fact, sometimes it is hard to get sound when you turn the volume is either full blast or silent.....lots of static like noise when...

This is an easy fix with a can of volume knob cleaner i think its called. You should be able to get it at radio shack. You just spray it into the volume knob and let it dry. The instructions are on the can.

Panasonic RF-B65 short wave radio won't tune to frequency when turned on, just flashes 'E' and turns off automatically. Any suggestions ?

RF-B65 has a known issue with the power connector on side. It gets resistive from not being used. If you apply 6 vdc and it works, its most likely the batteries or the power connector. If both produce a "E" its PLL doesnt lock. Power plug most likely issue. Another issue is the tuning knob. It skips or jumps irratically. The up/down frequency changes are by a cube 1/2 inch square contactor. Its not optical. Just simple mechanical contactor. Remove the small cube from chassis and spray liquid gold. It will clean wire contactor and lubricate internals. You cannot buy the cube. Cleaning it always works for me. RF-B65 radio is a sure winner. Small, reliable and very sensitive. Has SSB also. eter

you should try pushing the reset hole with a unfolded paper clip, or leaving the batteries out of the unit overnight

On HD-2 band

You need to make sure that the signal is strong enough. In the carrier to noise ratio you need to keep it above 55 db. Anything below that and HD will drop.

Use the SSI to determine C/N ratio and use that to aid in pointing the antenna.
