17 october 2009

the only thing of interest this morning was the manitoba classical on 950/1250 and thats about it my recordings deleted already so not much to talk about this morning on mw.

NOISE .....
the past few days i have had a couple of emails asking me about my noise level on mw infact the lack of noise i get when my flag antenna is inside the attic. for starters the village i am in is VERY rf quiet and at bedtime i have a routine to make sure everything electrical in my house is OFF! and i dont just mean on standby i unplug everything thats not needed to be on ie tv pc"s the only things that are left on is the freezer and the pc running the perseus and even the monitor for the pc is unplugged during overnight recordings.

its the same in the morning i get up and make sure no one has been up and left things on it may sound a bit over the top but every half a s point less in noise means that extra chance of a dx station coming in. its the same for my flag antenna and all i need to say about that is FERRITE get as much as you can at the receiver end and the feed point of the antenna and space some along your coax run as well as every bit helps especially on the mw band.

also watch out for mobile phone chargers as one morning i got up at my usual 05.00z and switched on the radio and all i got was BUZZZZZZZZZZZZZZZZZZZZZZZZZ all over the mw band i went and checked everything was off and they were but still the noise so i thought it must be something in a neighbours house but then i noiticed my wife had left her mobile phone in its charger so it was unplugged and the band was checked again and this time it was clean no noise so it just goes to show the things you dont first think of can cause you problems.
