Though ATS1 is primarily intended for 20 Mtr operationbut with same components with slight modification, as mentioned in the chart below, the same can be used in different bands.



The component values have been taken from an article by Dug DeMaw W1FB : Power-Fet Switches as RF amplifiers, QST April1989, 30-33 pp.

Would like to share some more inputs.

The VFO has to be of 2Mhz to operate on 40 Mtr. band

IF 9Mhz - Vfo 2Mhz= 7Mhz (40 Mtr.)

Hi guys I was looking at the frequency chart. I noticed that capacitor 135 is repeated twice perhaps isment to be C137 instead.

Thanks Luis
