Can<br>anyone say what the correct component is please? How should the trap C13/L3<br>be adjusted, it seems to have a range about 43 to 96MHz?<br><br>Please download the latest BOM, it has the corrected part number<br><br>U1<br>The BOM shows Digi-Key M25P16-VMW6G-ND which is a wide SOIC-8 part (in tube<br>packaging). The board has pads for the SOIC-8 which is Digi-Key<br>M25P16-VMN6TPCT-ND (cut tape), I don't know whether the wide part will fit.<br>Mouser have this part marked 'obsolete' by the way.<br><br>Corrected<br><br>A number of resistors, value 0R, are fitted across pads that are already<br>shorted on the PCB. Presumably these can
be left unfitted?<br><br>You may leave these unpopulated<br><br>R125 should be 536k (which matches the datasheet example for a 5 volt<br>regulator and the schematic). The BOM gives a Digi-Key part number<br>541-270KCCT-ND, which is 270k. For 536k, the part number should be<br>541-536KCCT-ND. 270k will give a 5 volt rail at about 2.9 volts.<br><br>Corrected<br><br>Please do let me know if you see anything else amiss,<br><br>73s,<br>Abhi</div></div></body></html>
