Graham and Tim, Thanks for your fast response to this issue.
As Jim mentions below, a 'hard' PTT to the Flexwire PTT IN and then on to key PSDR is the most reliable method. FlexRadio, work your magic and remedy this issue. 73 John ----- Original Message ----- From: "GI1CET" <gi1...@btinternet.com> To: <FlexRadio@flex-radio.biz> Sent: Tuesday, September 07, 2010 2:15 PM Subject: Re: [Flexradio] Flex-1500 external equipment sequencing issue... > > > Graham > > This one is currently as of this moment putting my 1500 purchase on hold, can you clarify which issue > is going to be fixed, > > Is it the delayed PTT timing one - > (Not sure that I would risk my PA or LNA to a timed PTT rather than a herd sequenced one!) > > Or is it the items raised by John re use with external sequencers which are critical for the use to which > I wish to put a new 1500. that is we should be able to apply a externally delayed PTT from an External > sequencer to the flexwire port PTT in and have that sent to PSDR as the PTT signal. > > Regards > > Jim, GI1CET > > On 07/09/2010 14:43, Graham Haddock wrote: > > > John: > > > > This has been assigned software tracking item D317 and it will be fixed > > before > > PowerSDR 2.0 goes to official release. > > > > --- Graham > > > > == > > > > On Tue, Sep 7, 2010 at 7:35 AM, Tim Ellison<telli...@itsco.com> wrote: > > > >> The FLEX-1500 is missing the control to set the time delay of RF after PTT. > >> This defect has been entered into the developers bug tracker and the > >> software engineers notified of it. > >> > >> > >> -Tim > >> > >> > >> -----Original Message----- > >> From:flexradio-boun...@flex-radio.biz [mailto: > >> flexradio-boun...@flex-radio.biz] On Behalf Of John Maetta > >> Sent: Tuesday, September 07, 2010 5:16 AM > >> To: 'FlexRadio Group' > >> Subject: [Flexradio] Flex-1500 external equipment sequencing issue... > >> > >> Gentlemen, > >> > >> My plans were to use the Flex-1500 for digital, CW and SSB EME (moonbounce) > >> and replace my TS-790 with transverters. > >> My current configuration is WSJT, VAC, Serial Port Manager and PowerSDR > >> 2.0.8.
