Station Sierra Sierra (meaning The Super Station) first began back in 1990 when a good friend of mine built me the first rig (after much arm twisting)
  It was a self oscillating 807 rig and a bit nasty to the crystals,but it put out a good 20 watts.
  At this time I was living in a flat above a shop,and the only place for the aerial was in the attic.The attic wasn't even big enough for a 48 m half wave dipole so I had to  invert the ends to form a 'Z' shape. Against all the odds and theories - the signal managed to escape the roof tiles and up into the atmosphere.
  Our usual frequency was 6540 KHz -due to the lack of 48 m crystals, however when there was space, some broadcasting was done on 48m
  To our surprise many letters arrived through the post from all over the place,which gave me even more inspiration for the station- but sadly I moved out of the flat so Station SS had to cease

  I moved in to a very heavily populated area, my new QTH only having only a small garden and no attic. It took me 7 years to realise that there may be a slim possibility that I could put up some kind of antenna for broadcasting, even though it may,and has had it's consequences. So I strung out a longwire and Station Sierra Sierra returned in 1998 on the 76m band.
  No improvements have been made to the aerial- apart from storm damage and
vandalism,but it seems to work. It is 32m in length (20m horizontal and 12m vertical at the furthest end). Several 'counterpoise wires' are strung out indoors to act as a dummy ground plane.
  I still use the same rig as before, but I rebuilt it in April 99 because the self
oscillating circuit was burning too many crystals out. It took a whole Easter weekend to build,and after several burnt fingers and electric shocks the new rig was on the air.
  It still uses the same 807 output device but incorporates a valve oscillator. The output is now 40 watts, which is a little over driven for this circuit but it seems to be ok.
  Provisions were made for direct modulation transformer input and choke mod input (which was used for the outdoor Galaxy broadcasts) . And by throwing a couple of switches changes the frequency range from 48m to 76m.
 
  Plans were made to use an old army 150 watt rig from this site,but I think I'd be taking the p**s with my neighbours.

  As you may see in our photo gallery- our equipment is nothing to shout about, but hopefully on your side it sounds ok.
  Our broadcasting times vary greatly for obvious reasons,but I hope you manage to catch our signal somewhere on 48 or 76m.
