Re: Winding quality of tricoils

Gerard,
Here are three more pictures of my v5 board:


All of the transformers as supplied by HFSignals are trifilar wound.  Not all windings are used in all locations.  This is on the schematic from HFSignals:

That is the case for the input and output of the SSB crystal filter.  You will have to zoom in to see that all are tifilar.

Hope this helps.
