How should I connect the additional 110v ac to 12v ac transformer I intend to use to supply isolated and rectified 12vDC power for the Freq counter and later a DDS??
TO THE 110Vac input line in SERIES and NOT Parallel as shown on power supply diag.?
Does it make any difference?
Well thats how I did it and the counter works well but the radio does not seem to power up.
2018-JAN-22? Looking into why…..? ?ANY relevant comments welcome…
The frequency counter fitted temporarily with cable ties to the top of the Tram D201 Speaker grill after the original full size speaker has been replaced with a smaller unit to allow for the counter to fit behind the grill.
The smaller speaker is OK but I always use an external one through a Behringer unit anyway.
