Dennis,
 
Don't worry about  operation on vlf, I= think=20 you find the band acts more like top band , with a well defined service area= =20 ~60/ 70 miles and a first skip round 200/250 , I can see a trace at Birmingh= am=20 with 500mW to my antenna , only real problem is the dreaded deep fade 'qsb'=20= whic=20 takes the signal out 30 seconds up to  1 minuet + , which causes havoc=20= with=20 rtty , as you have no idea if the other station copied anything .... dont=20 suppose you have amtor ?  
 
I doubt you will cause any interference=20 with  those power levels , I ran 20 watts to a inverted L  40= ft=20 x 40 ft for a long time , which radiated quite well , but after adding a top= =20 loading coil found it worked a lot better , with 150 watts and a new variome= ter=20 tuner , still didn't record any problems ..
 
Had more problems with the pc jamming the i= ncoming=20 signals and a funny long life bulb that radiated a well spaced spectrum acro= ss=20 the band  ! check out the pages on the google  uk500khz web news g= roup=20 for links to the grabbers etc .

Hi All,

 

After reading through loads of=20 stuff and monitoring the LF Group I=92m left with the decision of whether=20= to=20 start on 136 or 500KHz.

 

500KHz seems much easier to deal= =20 with from the outset, and hopefully the NoV period will be extended furthe= r=20 next year.

However the NoV itself is the=20 possible stumbling block in that it appears that experience on 136KHz is a= big=20 plus that Ofcom appear to be looking for,

 

My question is, would I get away= =20 with applying for a NoV without first being active on 136KHz, or has anyon= e=20 already taken this route and been successful?

 

73,

Lee M0LMH.
