Hi All,
Just read an article out of OSCAR NEWS about improving the 2mtr RX.
This is how it is done.......
Remove the 2mtr module , remove the top cover of the module,,, It the PA module
end of the unit you will find Q01, it is a Mos-Fet a 3SK74L2X.
Replace this with a BF982,,, the leads are slightly thicker than the original,
so a 1MM drill is required to open the holes on the PCB.
The LONG LEAD of the BF982 should be fitted facing away from the PA Module.
When the Fet is fitted a very small length of wire should be fitted from the
Source lead (The lead facing into the center of the board) to the surrounding
groundplane.
.
This should be it, but if you really want to be a perfectionist tune up on T01,
T02 and T03 ONLY!!
Finally, Box up and enjoy the low noise, improved signal reception.
73 for now
