[amsat-bb] Landwehr 70cm preamp device question?

Hello All,

I have an old Landwehr preamp that apparently uses the MGF1402 device (does that sound right?). It's not working so I presume it's the GaAsFET.

Can the MGF1302 be substituted for the original MGF1402? Or can anybody recommend another device for the 70 cm Landwehr?

I need to do something...

Thanks in advance!
