Because I am a visual reference type person, here is how I believe the Flex-1500 should work when using any digital mode. It does not matter if you use it on digital HF or as an digital IF for your VHF/UHF transverters,
The Flex-1500 does not currently operate this way, I have tested it. http://www.n6vmo.com/Otherstuff/sequencerdrawing.jpg 73 John N6VMO ----- Original Message ----- From: "John Maetta" <j.mae...@verizon.net> To: <FlexRadio@flex-radio.biz> Sent: Friday, September 17, 2010 2:59 PM Subject: Re: [Flexradio] [SPAM] Re: Flex-1500 external equipment sequencingissue... > Hi Brian, > > That is how my TS-790 based EME digital mode system functions. > Digital mode keys the RigBlaster via hardware comport 1, which routes PTT > and speaker audio to the sequencer (speaker audio passes unimpeded to the > radio's MIC).
