Independent, Simultaneous USB/LSB AM Sync Detector
Output from Sony ICF-2010
I've added independent USB/LSB AM Sync Detector output to one of my 2010 receivers...
It is easy to get the individual, hot-all-the-time, AM upper and lower audio on the PSN module
just below IC-10 on the main board.
I mounted a 4.7 uF tantalum capacitor to pin 4, and another to pin 5 (neg lead toward PSN).
The other end of each tantalum cap (postitive lead) goes to a 1/8" stereo phone jack's tip and ring contacts.
The sleeve of the jack was attached to ground on pin 6 of the PSN.
There is a slight level difference depending on which output is currently selected for use by
the rest of the radio, but that's not a big deal.
There you have it - independent, simultaneous reception of the upper and lower sides of an
AM signal in the 2010.
