Default Re: Kenwood TK-359 VCO adjustment.

David;

Well, having given my remaining pair of brain cells time to settle and folded my tongue back out of my cheek.....

The first hurdle at which I fall is that the TK-250 manual, or part thereof, that I have found and may or may not be similar to the TK-359 (the 200 series seem to be VHF and the 300 series UHF equivalents), does not give a layout or a complete circuit. It provides simplified extracts from specific part of the radio that tantalise but do not really help. Also, the internal layout and screening means that I cannot see what is what anyway. I suspect this last point is why the manual gives a measuring point on a connector - because you cannot easily get at much else. Its just where is it!

PS - By the way, if you ever need a signalling system designing for your monorail let me know.
