I've changed my YT Channel name to  :- 'Jimyjames73' to 'Jj73 - Locos / 3D Printer / Bike Rides / Exploring'

I have done this b/c...I've just changed my Channel Name to reflect a few things that I do on my Channel - The reason is interesting - another Friend on YT called C J Cambell who is into Military stuff & also just changed his Channel name has Notice that b/c of this Lock-down - loads of people are turning to YT b/c there is not much on TV & there fore more traffic - more views & that is why I'm doing this 'experiment' just to see what happens!!!

Hiya - I've just recently bought the GWR Freight Set (R1254) & the Hornby Dublo Train (with the Sir Nigel Gresley - R1252) & they both contain the 'New improved Hornby Basic Contolller' - R7229 & I have found that they make the locos noisy -  I've made a quick vid - to show you -

Pretty sure it's to do with the PWM control that it puts out - it can make the motors produce rather loud whining noises at a high pitch. 

 

If you are not sure what PWM is, click the link below.

Sam's Trains also briefly talks about the PWM whining with the R7229 when he reviews the controller here:

Looking at the first 5 minutes of Sam's video, the old Hornby controller he is comparing it against is also pwm. Unless it has different internals it is exactly the same one as I got with my Pendolino and it is PWM. I know because I had issues geting train lighting to work and looked at it on an oscilloscope. PWM is much better for driving DC motors and is much easier to generate using a digital device, hence why they use it.

I knew that the old Hornby Controller was PWM, I just thought that the fact he mentioned it and how it talks about it makes his locomotive whine might help JJ understand what is going on a bit more - and work out whether it is the PWM or a fault with his locomotive (which is unlikely.)

Hi

It is a shame that your video links about the 'new' Hornby controller were not publicised more. I have an old 1990's Hornby controller - no problems with noise of any kind, but as it is so old I bought the new controller. If I had seen your thread, and been aware of the issues I would have thought twice.

I still can't believe that Hornby would produce such a product.

Hi Keith

 

Sorry that you didn't see my vid untill it was too late - Yeah I know what you mean - I have quite a few controllers myself -  the H & M Duette (Best Ever!!! 😉) & 2000 (they don't make the Locos hum!!!), a few of the old Hornby basic Conroller (also don't make the Locos hum!!!) & the NEW Hornby Basic Controller R7229 which does make the Locos Hum - some thing to do with the PWM apparently!!!

Odd that - I have been using R7229 as my track power source when testing some DC and DCC projects controlling both DC and DCC-Fitted locos and there is no motor hum. Maybe it is individual motors that are affected.

What models were they?

Keith

 

Various small 0-4-0 steam and RR or Heavy diesel/electric, some plain DC, DCC-Ready with blanking plates and DCC-Fitted, either R8249 or TTS. Anything I have to hand.
