[Moon-net] [Moon] All I want for Christmas...

[Hugh VA3TO]

Yes Tom, I have a VE2ZAZ programmable sequencer 
(http://ve2zaz.net/TR_Seq/Downloads/QST_032007_Sequencer_VE2ZAZ.pdf) in 
service to:

1. switchover the relay
2. switch on the amp
3. key the radio

I forget how much delay I programmed in off the top of my head.
