My Roberts Stream 83i Internet Radio Resource page

First created 27 April 2011.  Last edited 3 Sep 2012

 

I won't bore you with the details as the Roberts Stream 83i has been on the market since the end of 2009 in the UK.  There should be plenty of reviews for this product.  This radio is based on a Frontier Silicon internet radio chipset.  The Pure Evoke Flow is probably its direct competitor in the UK.

The Stream 83i is supplied with a slim remote control, mains power adapter, and the radio supports both wifi and wired ethernet.  It is sold for between £120 and £150 in the UK by a number of leading retailers including John Lewis, Comet/Laskys and Amazon.

 

The new Roberts was purchased to replace the 4.5 years old Logik IR100 which has served us well.  It will be used for listening to a number of live internet radio stations.  The five front panel mounted memory preset buttons were one of the reasons for choosing this radio above other models as it would be used in the kitchen.

The Roberts is more neutral sounding unlike the brighter sounding Logik IR100.  The larger mono speaker and huge bass reflex port on the back of the Logik does give the Logik more punch and ability to fill a large room.  This is not to suggest the Roberts is poor, in fact it is very good.  Unlike the Logik, the Roberts does offer some ability to adjust the bass and treble to your taste if you don't like the half a dozen preset equaliser settings on offer.

 

It is unknown who is the actual OEM for the Stream 83i.    Roberts have historically offered rebadged radios manufactured by Sangean.

 

The backlit LCD display should be a far darker blue in colour than the above photograph suggests.

 

 


Not best for BBC On Demand

 

This radio, like many other internet radios, does not support transport controls for BBC On Demand WMA content.  ie. you cannot Pause, Rewind or Fast Forward to a particular time index within a particular BBC Listen-Again programme. 

If your internet or wireless connection is interrupted for any reason while you are listening to an On-Demand programme, it will cause the radio to halt, and perhaps commence play back from the start of the programme.  

 

(Some discontinued internet radios using the Reciva based internet radio modules, such as the Logik IR100, MX-200i, and Roberts Stream 201, do offer transport controls for BBC Listen Again WMA content when the latest/last beta firmware is specifically installed.)

3 Sep 2012: If you are looking for a new Reciva internet radio which offers transport controls for BBC Listen-Again content, the electrical superstore chain, Comet, currently offer the budget MagicBox Cleaver for less than £50. Forum link. Youtube links 1, 2, 3.

 


Alternative Remote Controller

 

The Stream 83i remote is nicely made and actually feels very weighty.  Unfortunately, I personally find the membrane buttons on the remote to be very difficult to depress unlike other membrane remotes I have used.

At the time of writing, I've had no success to getting any of my universal learning remotes to operate this radio.   The SRM-403E does not recognise the IR codes emitted by the slim remote.  My OneForAll learning remotes appear to be able to learn the codes emitted by the Roberts remote, but are unable to use the learned codes to remote control the Roberts.  Puzzling....

(Update)  However, I was successfully able to use the extracted EFC data shown below, to create a new device setup code, which I subsequently uploaded to my URC-7556 OFA universal remote.  It was able to successfully remote operate the Stream 83i.

 

Learned IR code data extracted using via the JP1.2 serial cable connected to URC-7555 learning remote:

I've not yet found a OneForAll device setup code which can emulate NECx1 protocol with device/sub-device 136/136, so it looks like it will not be possible to use a generic OFA universal remote with Key Magic to operate the Stream 83i.

 

 

Random Freezing and Rebooting

(Added 17 Sep 11)

One of the first things I tested when I got the radio, was to see how it behaved if the internet connection was interrupted while listening to a station.

When I momentarily disconnected the ADSL cable from my router, causing an interruption to the internet connection, the radio would in most cases, eventually re-establish a connection to the radio. On other occasions, the radio would just stop and fail to reconnect (In particularly with Real Audio streams). The radio also completely froze on one occasion when I disconnected the ADSL cable – I had to completely power off the radio at the mains wall socket to resolve the problem.

It is evident the radio doesn't always tolerate a 'less than perfect' internet connection. A disruption or weak wifi signal between the router and the radio may cause similar problems.



I have read if the radio spontaneously reboots for no obvious reason, you should change the Software Updates setting so it does not check automatically for firmware updates.



I always configure my internet radios to use a static IP address. If you frequently switch off your router, or it randomly reboots, the use of a static IP address may prevent conflicting IP address issues which often occur when most routers are restarted.




Wireless signal strength doubts



Compared to my collection of older Reciva based internet radios, I'd have to say the wireless on the Roberts is slightly inferior to the Logik IR100 it replaced, when positioned in exactly the same location in the kitchen.

The aerial on the back of the Roberts is only used for FM/DAB reception.

Manufacture Date

 

This is by no means conclusive, but I think the first 5 digits of the serial number found on the small label attached to the rear of the radio, and on the original packaging just below the bar code, may perhaps reveal when the radio was manufactured or is used to indicate which firmware is installed at the factory.  Of the two radios I have seen, the radios have serial numbers commencing:

 

N1010        October 2010 ? with factory installed v2.0.16.25756-1B13 firmware

N0311        March 2011 ? with  factory installed v2.0.21.33366-1B16 firmware

 

I was probably just unlucky, but the first radio I received with serial number beginning N0311 had a minor audio amplifier fault.  It was replaced by the retailer with a radio from an older batch, beginning N1010.

 

 


Mains Power Adapter

 

The Stream 83i is supplied with a typical UK 3 pin switched-mode mains power adapter.  

It is rated at 12v @ 1.5A DC output for operating at 230V AC input.  

The standard barrel plug is 5.5mm outer diameter/2.5mm inner diameter with centre positive polarity.

It appears further disassembly is required to reveal the main circuit board.
