Well done to you Colin for getting it over the line and moving a little bit with them. First class.

Thanks, yes it was the right thing to do in the situation.

Well done for sticking with it colin and it’s good that the company eventually listened and resolved the problem!

Thanks mate. Got there in the end.

I sold computer systems that were built by a custom builder to my customers that were mostly used for personal use. The company offered an economy line of PC units I decided to give a try. The customer called and complained about RF noise in their AM broadcast radio when they tried to listen to the baseball game if the computer was running. I replaced the power supply with a different model and it took care of any noise. The offending power supply was almost half the weight of the replacement unit and the circuit board was about half the size.

That's interesting. Sounds like a lot of cut corners.

Glad you got things worked out! I've been gathering parts for a new PC build and ordered a Gold rated Corsair RM series PSU due to reports of reliability and the companies Excellent Warranty. I also ordered a quiet case without a window for better shielding and minimal sound from fans. Hope to get it working soon. I'm an Old School, Analog only PS for my rigs guy to keep Hash away. Thanks for the Info! 73 mike

Hopefully this new one lasts a very long time. I did have a cheapo one years ago that fried the motherboard.

I use an old server power supply (Astec DS550-3) to power my radio, no issues with noise. Solar power inverters seem to be the big noise offenders where I live.

Yes, lots seem to be fine. Not this one though.

Yes sir, sounds like a pirate station to me. Thanks for the video, nice to see someone else Dxing.

Great information! Operating any device along the linear slope of its curve is always better than pushing it too hard into the high end close to the knee and if your requirements are considerably lower than its highest rating is, you're in an ideal situation. Thanks for sharing!

Very true, the new PSU is just ticking over.

Congratuations on getting this fixed. My current problem is with 19 and 22 inch LCD monitors that I have. They all generate RFI in terms of blocks of noise and close spaced carriers. It seems to radiate from the panel itself. Any idea on how to suppress this ? I found that wrapping in chicken wire solves the problem but it is not really a practical solution ;-) I have gone over to using laptops as they seem much quieter in terms of EMC.

@MM0OPXFieldRadio 3 ай бұрын

Never had issues with monitors. Just glad i got it resolved.

nice one colin. I used to have a really expensive computer system, and had nothing but problems in the shack. Then I spoke to a ham radio guy who had a computer shop. Ended up with the cheapest computer you could imagined, no more problems hi hi. But generally many electronic companies do not understand rfi. I did a wee video about my original computer and rfi on my radio, sent it to the company, and I was fully compensated. 73 mate. Look forward to seeing on the beach again soon, love those videos.

Thanks mate. I'm just glad its sorted. its good you got an understanding person with your problem. My radio was just unusable in the shack. On a different topic, I missed out on the great morning grey line on Saturday morn. Tried Roly ZL1BQD on Sunday morning when condx not as good, he heard me 559 but I could barely make him out. Sods law this morning when I'm back at work he said condx were great into UK. This coming weekend hopefully I can try again. Cheers, 73.

yeap. Collin I totally agree. This was one reason I sold my desktop Pc and bought a powerful Mini PC with a shielded case and external power brick.Running everything though through a APC ups battery run. Quiet as a butterfly :-) 73

Mini PC's are incredible these days. Good shout.

Switching power supplies can be horrible and sometimes they seem to b okay but I avoid them when I can

Yes designed correctly theres no issue.

Interesting tale Colin. Glad you got it sorted out. My shack computer is a raspberry pi 😂

@MM0OPXFieldRadio 11 ай бұрын

Me too. Still to get into Rasp Pi.

@theradiorover 11 ай бұрын

@MM0OPXFieldRadio I have an APRS digipeater, a media server and my shack PC all on Raspberry Pi's and I'm no expert in Linux. Next one will be a QO-100/SDR system if I ever get my arse in gear. 🤣

@simonappleby4224 11 ай бұрын

My CCTV night vision stopped working and on contacting the company, they said that it was the power supply. I bought a new one and yes, when I turned on the radio massive interference. I didn't put two and two together at first but I got the light bulb moment in the middle of the night and on turning off the CCTV the problem went away. So I got a different power supply and everything is OK but I suppose not many people would even think of RF being generated by an appliance. . .

@MM0OPXFieldRadio 11 ай бұрын

Had similar issues with IKEA switch mode PSU's for low voltage lighting.

@g0fvt 11 ай бұрын

Glad you got it resolved, to be honest there is no downside to having a larger power supply than you need. Like many of the other commenters the only computer directly connected to my ham gear is a headless Raspberry Pi. Switch mode supplies get a lot of bad press for RFI but well designed ones can be very good, of course many flagship HF rigs have them internally. 73

@MM0OPXFieldRadio 11 ай бұрын

Ive used Switchmode PSU's for my radios from the start and never had an issue with one of them.

@Rubedo777 11 ай бұрын

Well that’s a story to keep in mind. As most have a computer linked to radio operations I think if I’m going to get one I will be telling them what environment it will be working in and is it RFI / EMC compliant and I want it in writing if they say yes. We have enough to put up with all the crap from solar/ air conditioning/ fairy lights/ kids toys and all the other cheap stuff people use in the house without a care or concern for the likes of us. I’m pleased you found it so quickly and eventually got it sorted with the computer builders ✅ well done on that.💎

@MM0OPXFieldRadio 11 ай бұрын

Thanks. Yes, its a continual battle! if its CE approved it should be good but not always the case.

@PIXscotland 11 ай бұрын

I see the manufacturer states the CV isn't UL certified where the RM is.

Very interesting, I never thought to check this. I will in future.

Hi Colin. Its a big issue regarding EMC and interference. I will produce a video showing what I have found out regarding my inference noise problems. I will send you the link. Cheers from old George. My latest upload 28th February. G1BKI

Yeah its terrible and not going to get any better for us unless we live on our own away from civilization.

@OzzieKev 11 ай бұрын

Had a similar problem with a HP laptop I was given. It had an aftermarket power supply that caused lots of RFI. I was able to swap it for a genuine HP supply and the problem disappeared.

Imagine a neighbour with this and nothing you could do about it!

@jimcaddis9417 11 ай бұрын

Had the same issue and if you had a waterfall on your rig you would spot it right across the band, mine was really bad on 10M. My wife was using a bequiet 550 bronze psu I had a Seasonic gold 600 psu, it was the bequiet causing the problems. I upgraded to a Seasonic 700 gold problem solved.

@MM0OPXFieldRadio 11 ай бұрын

I did see it on my 705 That I was using as a sniffer. Interesting to know the BeQuiet was noisy too.

@muffin_j_lord 11 ай бұрын

I used to have a drawing tablet that would throw up big RFI every hundred hertz or so across 20m. You never know quite what's going to clear up when you start turning off everything in your environment!

@MM0OPXFieldRadio 11 ай бұрын

Yep, that was the interval on mine too. Worst on 20m.

@Ei2iP 11 ай бұрын

I don't know, I've 3 x 27 " monitors, high power pc, and run both SDR and physical radios and zero issues, no hash, nothing.

Only Issue Ive had in 20+ years. Heard of others with issues with HDMI cables.

@GoonyMclinux 11 ай бұрын

I have a monitor that all the sudden went nuts with RF noise, before that a laptop power supply was shorting and threw up a bunch of noise all over a few bands. A neighbor across the streets electrical box was shorting and wiped all of HF for a few days. Stuff just happens sometimes. 🤷‍♂️

@GoAmateurRadio 11 ай бұрын

I had the same problem with a power supply. I replaced it with a quiet power supply.

And did you contact Corsair for their feedback and a chance to test a range of their PSUs?

@MM0OPXFieldRadio 11 ай бұрын

No, because my contract was with the builder. I had to go through them. its up to them to take this up with Corsair. They wouldn't let my try a range of PSU's for free either I bet.
