Ham Radio & PLT devices 

I use 3 PLTs (cheap d link ones £25) and they cause absolutely no additional noise here. Perhaps it was the older models that caused the problems and the manufacturers got their acts together?

Er, excuse me. How much data was transferring when you tested? They're obviously not going to make much interference when you're not transferring any data. Also not clear how you claimed you had switched both of them off with the click of a single switch?

Hi Dan I tested a pair that talk talk supply and they produced noise outside the Ham bands. I have a few I can hear around here but the Ham Bands are notched and when not rx/txing data they are quiet. You did test yours when doing a large file transfer :) Cheers Paul m0pnn

I have three telephones that run on PLT system (one base and two other handsets) and they have never caused any interference on HF or VHF/UHF. Well done for demonstrating though - a good review.

Well done mate. It looks like you are in a "new build" house so maybe with the wiring being new it is not causing the dreaded noise. Will have to do the test here in this old house with wiring installed by Eddistone and Watt.....

Great video mate....put a few rumours to bed with this one.Camera/image quality very good by the way catch you later

Good job! I bet you just sold a whole whack of that specific brand of device.

Good review Dan with very interesting results which i must admit surprised me, i may give them a try

If you have a wooden house, there is no difficulty nailing an ethernet cable along the celing or door frames. A pair of Mikrotik routers with a directional antenna could transmit it wirelessly on an unlicensed low frequency.

I found the same thing NOT ONE BIT OF NOISE

I found exactly the same......no noise over the whole 1-30mhz spectrum. The power supply for my virgin media super hub router however, is horrendous!!! These small 'wall wart' type psu's are really bad for loading house wiring with interference and one or two in my house have found their way to the bin.

that because the newer plt devices have to notch out on the main ham bands to conform to new specs,,this does not seem to include warc and uk 27/81 cb bands,,,also there not notched out on shartwave,,try doing a vid listening o shortwave with the plt turned on,,it near impossible to hear anything ,,,ham that are getting noise from plt on ham band are using older units or bought out of spec rubbish off ebay etc......if you need more wifi range install a wifi repeater they work very well

Early units used did not notch out ham bands,,many of these can still be in use today,,newer unit it no a problem on ham bands,,but on shortwave and cb it's still a problem.,,,but does high power transmissions interfere with plt devices i wonder.

Did you [can you] test 2m/70cm bands as well or just HF?

I have S8 of noise on 20 and 40m but on 11m just down to S2.

I ran on of these for 6 months when I had the shack in my garden shed, out of wifi range, this was before everyone started shouting about the interference. I have to say my findings were like yours, it made no difference.

Thanks it's a great test. So many sources of interference, finding them is the issue.
