- 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
