Hi, K2 #4114 is now up and running on CW, I have a query about T1 and T2 
on the KSB2 board.

On the drawing of the toroid ( page 11 ) the secondary winding is shown  
wound in the opposite sense to the primary winding ( primary wound 
clockwise and secondary wound anti-clockwise ). Is this correct? as I'm 
damned if I can get the thing to look anything like right, or to wind it at all... 
too many turns and too small a core.

As for the K160RX kit. I had missing parts, C2 was'nt there and instead of a 
470pF capacitor for C75 I had a 470R 1/4w resistor.

On the K2 Control board I had two duff 2N7000's. At first I thought I had 
stuffed them with static from my Iron, but after having it tested at the local 
PMR firm It has been declared 'safe' so the bits were delivered faulty. No 
problem though as I have replaced them from Farnell.

all good fun and games.
