The features include:

  • Adjustable digital squelch
  • Monitor button
  • 8 memory channels

What’s in the box?

The radio is supplied with a generous 1500mAh battery pack (5 x 1.2v AA 1500mah rechargeable cells) and also includes the battery charger. You also receive a belt clip and the user manual.

Performance

The build quality of the radio is good, it feels sturdy and has a nice weight to it. The volume knob also acts as the on/off switch which has a nice positive click and smooth action. All the main buttons are positioned on the front of the radio and are clearly labelled. The short antenna is sturdy and certainly doesn’t feel like it will snap off given the slightest knock!

Intek MT-5050 Keys and LCDTurning the radio on for the first time I was greeted with the large channel readout on the display. The display is really easy to view and it shows all the current settings such as channel number, CTCSS, roger beep on/off etc.
In low light you can also press the light key which back lights the display with a green lamp.

The 69 LPD channels are numbered 1-69 and the PMR446 channels are numbered P1-P8.
Moving through the menu system is really simple, it’s just a case of pressing the menu button to cycle through each of the levels and to adjust these you use the up/down arrow keys. To exit the menu you can press the PTT or call button.

The first setting I adjusted was the squelch level, it was initially set at level 3 but I found level 1 was acceptable. I then tested the “monitor” button on the front of the radio which opens the squelch fully and I was pleased to see that it doesn’t require you to hold it down like a lot of other radios, you just press it once and the squelch stays open, press it again and the squelch kicks in again.

Hitting the scan button started a scan and it didn’t take long before I was listening to various local repeaters on the 70cm amateur band on the LPD channels. They were all coming through as clear as they normally do on my various other radios so the sensitivity certainly seems adequate considering the small antenna and indoor location.

The audio quality from the built in speaker is also perfectly acceptable, I’ve found it to have a clean output with very little distortion even at higher levels of volume.

Testing the radio on transmit I was really happy with the quality of the transmitted audio as well, very clean output and the audio is of a decent level. On the PMR channels the transmit power can be set to 500mw or 10mw. Out of the box you can only select the 10mw setting for the LPD channels.

Another nice feature which is often forgotten about on these types of radios is the signal/RF meter. This meter is a 6 bar meter which gives an indication of the received signal strength and also gives an indication of RF output while transmitting.

The radio has 8 memory channels and I’ve found the best way to utilise these is to store the 8 PMR446 channels into them. The reason for this is that the scan feature mentioned above scans all the channels at once, you can’t choose to scan just the PMR446 or LPD channels alone, but if you put the PMR446 channels into the memories you can perform a memory scan of these alone, problem solved!

The two tone roger beep can be switched on or off via the menu system and you can tell when it’s switched on as there’s an icon on the display to let you know. There are also 3 call tones you can choose from. To send the call tone you simply press the “call” button on the front of the radio and it transmits the tone.
Overall the radio is a pleasure to operate, very straightforward to use and seems to perform great.

Modifications

MT-5050 ModificationThe following is for educational purposes only and if you undertake these modifications I take no responsibility if any damage occurs!  This radio is easily modified by cutting wire links hidden underneath a small piece of plastic inside the battery compartment.

The benefits of modifying the radio are that you can increase the RF output to 4 watts and also enable the voice scrambler. Additionally you can also expand the number of channels available.

The diagram on the right shows the radio sideways with the base/bottom of the radio to the right.

If you wish to leave the channels as they are but enable the higher power output and the voice scrambler, you need to cut link C.
If you wish to enable the extra power, scrambler and additional frequencies, you need to cut all three links.
Once these modifications are complete, you can transmit 4 watts or 0.5 watts on all channels.

To enable the voice scrambler you hold down the light button on the front panel for a few seconds and you can then select between the 2 scrambling methods using the up/down keys.

When testing the scramblers effectiveness it certainly did a great job of scrambling the audio to the point it’s completely unreadable to a casual listener. To make use of this feature you would obviously need two of these radios to be able to decode the scrambled audio.

The additional channels gained are quite extensive, what you end up with is 99 LPD channels, 30 PMR446 channels and 20 PMR/LPD semi-duplex channels.

Conclusion

If you’re looking for a PMR446 radio that doesn’t feel and look like a childs toy this is definitely the one for you. It’s well constructed, has a large easy to read to display and is simple to operate. The received and transmitted audio are both great quality and it has most features anyone could ever need on this type of radio.

The radio is available from Rocket Radio priced at £59.95.

  1. Hi,

    Can you tell me what extra channels / frequencies are available after cutting the links, or where I can find this information please ?

    Regards,

    Nick

  2. if you have a scanner run scanner from 433.000MHz, now turn your Intek mt-5050 on lpd channels find the last number it scans now keep your PTT pressed in your scanner should stop at that number on your scanner giving you the last frequency, from there work back to each number.

  3. Which link do you cut if you only want to enable 4W Tx? Once the link is cut can you toggle between 0.5W and 4W?

  4. Have seen the modified version on sale on eBay. Is it illegal to buy one of these and import to UK or is it just illegal to use? It seems strange that seller is operating from within EU which would suggest that they are breaking the law by selling the modifie device. The price is good and includes a headset but I don’t fancy getting into trouble over it.
    Cheers,
    Jimbo

    • It isn’t illegal to sell a modified radio. As its impossible to tell what power output a radio is putting out to a listener, there’s very little risk is using a modified unit. Just don’t interfere with other users tramnsmissions (ie radio hams)

  5. Hi,

    I am a complete novice… I mean complete. This is helpful but all I want to do is to be able to speak to my team member in an emergency and I simply do not know how. This is the first radio I have had. He has used others but not like this. Please someone help us.

    Thanks

    Read the ‘mixed’ but mainly posative reviews on various sites and decided to purchase. Mistake!
    Even after the well publicized mods and two new large aerials, poor performance. A set of cheap ‘walkie talkies’ would perform better. In fact I have a pair and they do.
    Waist of money I’m afraid. You will be very lucky to get a mile in a built up area, and even in the open if there’s the smallest hill between radios’s….forget it!
    I can only presume those giving positive feedback must reside in extremely flat non-residential areas with no obsticals whatsoever as any excuse not to work and they don’t!
    Spend £25 on a budget set not £200 on two of these.
    Sorry to be negative but this is my experince.
    DTM.

    • I’ve had contacts on these radios over 60 miles away. No problem at all. All transceivers in towns (including the police) will not TX more than a mile. That’s where repeaters come in! Set up a PMR446 repeater with your mates.
      Do a Google to find out more. The 5050 radios are a hundred times better than anything else available. Ensure you’ve got your radios set on high power and are modified.

  7. i am happy to say these work work great you do the extra mod i bought 1 of these from new and think there there great. I can also so they can work for miles as long as its clean sight to sight you wont have any troubles at all. AND DEFO with a buy.

  8. The intek is not a bad radio, there are plenty of handy features .
    In reply to the chap who says he has one modified, and that its no good must be on a wind up.
    In a built up area all 446 radios are going to struggle, for what they cost you will be hard puished to get better at around the same price..

  9. Hello,

    I want to buy the Intek MT-5050 (4W).
    But can anyone tell me how long the battery will last with normal use with the 4W version? instead of the 0.5W?

    And is this radio with range and quality similar to the radio motorola TLKR80 extreme? Or better?

  10. Hi,

    Can anyone tell me if its possible to select dual watch on the MT 5050 and then lock the keypad?

    Pressing the LOCK key (same as SCAN) for a couple of seconds as required, results in losing my dual watch settings.

    Maybe I’m doing something wrong, so please help.

    Thanks.
