[amsat-bb] Re: Landwehr 2m preamp GaAsFET?

[Glen Zook <gzook@xxxxxxxxx>]

I don't know which GaAsFET they used, but the 2SC2498 or 2SC2570A are rated at 1 dB of noise or less and they are relatively cheap.  The more expensive replacement type (i.e. ECG) are ECG10 or SK9139.

Does anyone know what the Landwehr pre-amps used for the GaAsFET?
 
I don't see any markings on the device, and one of the former resellers (Radio Dan) doesn't know either...
