[amsat-bb] funcube dongle

[gkcarr at go-express.net]

I too use the dongle with the laptop strictly for receive. The xmtr is on a separate feedline and I switch the two feedlines according to the V/u or U/V configuration of the satellite.

Jeff,

Like Alan, I use a manual system to switch between the transceiver and
the FCD. When I am receiving on the FCD, there is no transmitter
connected to any feedlines for that band. I manually disconnect it
from the radio and connect it directly to the FCD. Thus far, this
technique has managed to dodge my incompetence and protect my precious
dongle.

I have plans to incorporate relays at some point down the road.
