[Icom] Last Word on Internal Keying Relays (I hope...)

Mon, 25 Mar 2002 20:44:35 -0500

Bruce I never said I didn't trust Adam. He has been very helpful. I do not
have a meter to do so but I do know that the keying specs for the 91B is 25
vdc unkeyed and 7 ma keyed. That is straight from Alpha's web site spec
page. It also does not call for n external box for hooking up 756 and up
series radios. just a shielded RCA to RCA cable, just like I use with my
FT1000D now. No offense but I have never doubted Adam. Thank you and 73,
Steve, NX1G
