Quick Peep at "the shack" ... I've had a clear out!
Well you couldn't really call it a proper shack as it is situated within the house, however I prefer to call it the "Operating Desk" which seems more suited.
Shack update at July 2017, I recently took stock of all my radio's (Yaesu FT2000, Icom IC7200, Yaesu FT897D, Yaesu FT7900 and Kenwood TS590S/
I realised that I was only using the 897D for portable work and the Kenwood TS590S in the shack, I love the way the TS590 works and could not be more pleased with the results.
I looked hard at my operating usage and I only used two rigs, one for portable and one in the shack, so I made a hard decision, had a clear out and saw my good friend Richard at Martin Lynch and Sons to see what could be done.
I was interested in the new Icom IC7300 which appears popular however I was swayed by the already smitten operation of the Kenwood, having played with both the 7300 and 590SG side by side, in my mind there was no competition so I opted for a brand new Kenwood TS590 SG.
Equipment at July 2017.
Kenwood TS590 SG and Yaesu FT 7900.
Electromagnetic compatibility - the Amateur Radio Operators "nightmare"
Recently I have been exposed to some 20db+ noise! I initially found this at 14.030 however it is local to my location and hits just about every band apart from 40m's.
Here are some of the frequencies I have found the same noise located:-
3.746, 21.051, 21.285, 28.068, 28.302, 28.418, 28.536, 50.174, 50.290 and 50.407.
Here's a link to a you tube video I published recording the noise.
I have isolated the house electrics by running the radio off a car battery and also taken batteries out of every house bound appliance such as smoke alarms, CO2 sensors, the wireless weather station, my digital wireless clock and also removed from the house touch lamps and anything that has rechargeable DC power like the BT handsets and all my testing equipment such as my GDO and any equipment that produces oscillator noise. Guess what? still there! I even disconnected the solar LED garden lights in the garden but again, no change.
Two things have changed in the last 6 months near my QTH, the first was the replacement yellow illuminated street lamp outside my property to an LED and the second the (compulsory) installation of smart RF transmitting electronic water meters.
I shall be doing some investigating locally with my 897D and a loop antenna to see if I can discover the source.
If you recognise the source sound and can enlighten me to the probable device causing the interference please email me with your suggestions.
