BITX20 - 6. Measuring the VFO

Just a small progress update on the BITX.....
A while back i build the vfo part and started to do all the measuring as discribed in the manual....
Unfortunately the value's described in the manual is no where near what it should be....
So i emailed an other ham operator who has build 2 already to see if my value's rang a bell....
And they did :) thanks PD1ED.

I am sure other people will have the same experience... So i will share this info as well.
Or, if you are into yahoo groups, do join the BITX20 group there. It's a real goos source of info.

Current drain, 34,8mA, not 44,4mA

Q5:
E: 7.21v 4.76v
B: 6.96v 4.87v
C: 8.48v 9.88v

Q6

E: 6.36v 3.99v
B: 7.08v 4.66v
C: 8.48v 9.89v

You can see how much the difference is and then, if not told you will start to worry like me.
(These are my measurements, please remember that they can differ to yours as components, testleads and multimeter's have various deviations)

Well , next weekend on to making transformers....
