Question about Maxon 49-HX 2-Way Radio

1 Answer

Lots of noise!!

Hi,

I have been donated 2 49-HX radios from work which were just gathering dust and have not been used for so long that their batteries have oozed nasty stuff everywhere. However, I've cleaned up the battery contacts and found they both work ok except one is very prone to noise pick up. It picks up shash 95% of the time and only handling the box or aerial may temporarily stop it.

I've opened up to dodgy unit and found that if i touch various legs of different components with my finger or a non-insulated screw driver, the noise cuts out and the radio works perfectly.

I can't see any dry joints or loose components/wires etc. Is there something obvious I may have missed that would cause this.

Thanks for your time.

Seems to me you have a grounding problem. try grounding it. take a length of wire, strip both ends, twist one end of it to the antennea and the other end to any metallic object thats stuck to the earth. see if it goes away. but remember to remove it when you switch off or during a electrical storm.

Have you done a processor reset? It will clear up many problems. For some reason radios need to have the processor reset every so often. Lots of Ed going around the unit. Try that first.

The Am tuner module may be faulty and needs replacing. It would need to be looked at by a radion technician

Fan/ engine whining sound


If the fan is only making wind noise it is ok. If it is making matalic noise replace fan. It would be a good idea to clean (blow)out the dust and dirt for the inside of the computer at this time.

Your M/C is generating RF(radio frequency) energy from the electrical system. I wish I could tell you exactly where the problem is but there are to many places that could cause this problem. some possible problem areas are the alternator, spark plugs etc. You might consider upgradding to a set of newer radios. this may be cheaper than trying to figure what area of the M/C is generating RF Energy
