Question about Maxon 49-HX 2-Way Radio

1 Answer

Lots of noise!!


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.

Re: Lots of noise!!

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.

What version of software is needed to program the motorola radius sp50?

Agreed, plus the SP50 radios use DOS software. They are not narrow band capable. We have alot with chargers we will not even donate due to the non compliance with the FCC Rules. If you want parts, email me:

Hi would you have a circuit diagram for a microphone for a smx4150 mobile 2 way radio?

It's 3 wires, very simple, Ground, Key and Mic Element. Short 2 until u hear the xmit go on, then touch any to the case, that is the "key" the other is the ground.

The remaining one is the mic relative to ground and u can draw u'r own schematic.... Best regards.... MarSay Group

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

Motorola FV500 - lots and lots of noise on line..

Hello hanshez,

It's also possible that the noise is being caused by local interence. You could try using a different channel. Disable your interference eliminator function and try listening to the various channels to find a quiet one. The interference codes don't actually eliminate interference they just keep you from hearing activity on the channel that can still interfere with your communications.

As long as there isn't other activity on the channel your radios should be able to communcate. Are the radios able to communicate with each other when you are in the same room? Does the problem occur when your son gets further away? Or when he is outside and you are inside? If so, the issue may be one of range.

These kinds of two-way radios are very good for communiations when the users are within line-of-sight of each other. However communications can become blocked by tall trees and buildings, if one user is inside a building or automobile, etc. The 8-mile range that Motorola lists is really only practical when one user has some altitude over the other and clear line-of-sight, such as being on top of a tall hill outdoors with no nearby buildings. For typical communications over relatively flat ground with no obstructions, I would expect a more typical range of less then one mile. Obstructions can lower this effective communications range even more.

Hope this helps.
