I found those 4.224 Crystal oscillators (ex equipment) on eBay .
Divide 4224 by 32 (first 8 and then make the quadrature signals), and the LO frequency ends up on 132 kHz. Not bad for a 136 kHz SDR.
21 July 6m band open to Thailand - All time new HS at 50MHz never seen before Thailand since QRV last 3 solar cycles... Psk reporter map very ...
