[amsat-bb] Re: Pre-Amp power

[Bob Stewart <bob@xxxxxxxxxx>]

Perhaps I missed it, but I don't remember anyone pointing
out that the preamp is essentially off in transmit mode.  Considering
that transmit normally uses a lot more than 180ma on most
rigs, there should be plenty of extra power available in receive 
mode.  On the ARR preamps, there is only 10ma used during 
transmit.  It's hard to think that any rig's PSU wouldn't have 
an extra 10ma available during transmit.
