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.

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... George, KA3HSW _______________________________________________ Sent via AMSAT-BB@amsat.org.
