Pippo, The exact value of R20 is not so critical, although all the datasheet typical applications use 2.7 ohms. I would suggest that you use the resistor supplied.
You may also want to check the accuracy of your DMM when measuring small resistance values. Some meters provide for a zeroing adjustment to compensate for probe resistance. A loose fitting probe could cause errors when measuring very low resistances. As a sanity check for your meter, measure the 1/2 watt resistor on the RF Board resistor strip, it should measure close to 1.5 ohms. 73, Don W3FPR On 10/4/2010 7:58 AM, IZ2NYY wrote: > Hy to all, installing the resistor R20 on the control board i checked, as > usual, the value before soldering.
