This is our HF1 Operating position. The FLEX-5000A is a software defined radio. This page is a summary to guide you through its use. All users need to read the full manual, practice receiving with the software, and meet with Dr. Garlitz before getting the OK to transmit.	This radio transmits on the 80-6m HF bands. Members can only operate in the frequency spectrum they are licensed for. Digital modes are accessed using Ham Radio Deluxe and DM780 software. Full manuals are on the computer desktop and a summary follows.
	The power supply is an Astron switching supply located on the left side of the desk. Above it is an antenna switch that gives you choices for various dipoles.
Match an antenna to a Rig using a short coax jumper. Choices for the FLEX are the Pro-67 Yagi and the Antenna Switch.	Never Operate without an antenna. Use the autotuner feature. Stop transmitting if the software indicates a High SWR. ALWAYS DISCONNECT the ANTENNAS BEFORE LEAVING!
