George,

Unless you enjoy repairing stuff, and many do, I would just send it in.  ARR will do a good job,
quickly, and right.  Not all GaAsFETs are equal, and they will check the noise figure and gain as part
of the checkout before shipping.

Subject: [amsat-bb] ARR preamp repair

Anybody ever try fixing an ARR P432VDG preamp yourself?  I was recently 
given one that I suspect was transmitted into.  Drawing more current than 
spec'd (45 mA vs. spec of 25), no S-meter increase when connected.  Or am I 
better off just sending it in?  ARR's website says most GaAsFET preamp 
repairs run around $22.50 plus shipping...
