AMRAD & 6m Packet mod Project

[Tom Azlin, N4ZPT]

Hi Bob,

Sorry I missed the meeting. I was down at the Mount Vernon club giving a 
D-Star briefing. Do you use a high voltage DC/DC converter to get the 
primary battery down to 12Vdc?  And did you put in a lithium primary 
battery??

73, Tom n4zpt
