RE: [drakelist] L4B and L7

[Jim Roik]

I believe the voltage is around 36 V.   Do not try and key the amplifier directly with the pro 2. The output contacts in the Pro2 do not have sufficient rating for the amplifier. Use a small relay between the Icom and the amplifier. I believe that you can buy an interface, but you just need a small relay and wet it with 12 VDC. I used a Potter and Brumfield plugin relay.   Failure to do this will likely cause the contact in the Pro2 to weld together.   Jim  VA7JR -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of S.

I want to make sure I do not damage an Icom 756 Pro 2. I really appreciate any info
