I was assuming that the various UCBs were going to trigger external relays, presumably via X2-12 in particular (that's the all-mode one, right?). The only issue there was how much current the X2 interface could take. I was assuming we'd have to buffer it in some fashion with a higher current discrete transistor or something. The rest I though was more or less already happening in the existing rig. Is there something I don't understand? The reason I ask is that I manually switch T/R today (without using the X2-12 at all, just externally key the coax switch by an electromagnetic relay). However, for reasons that seem obscure, sometimes the rig desenses. Is there something I don't know? Is the rig at risk? Except for the desense, seems to be working just fine. Larry WO0Z
[Flexradio] Saving ATU Bypass-Memory-Full
IN earlier releases of PowerSDR console, when the ATU’s “Memory” was selected, I believe this info was saved so those of us who have the tuner did not have to “select it” each time Power SDR is executed. Maybe there some reason why the ATU info is not being saved? I would like to see what ever info was last selected for the ATU (Bypass, Memory or Full), remain until changed by the user. Mel, K0PFX

Re: [Flexradio] Auto enable VAC for DRM?
Does anyone disagree with this idea? If not, I will add it for the next version. Note that if you don’t use Auto VAC or DRM, then this change will not affect you.

Re: [Flexradio] Mute for SDR Receiver
Good idea! Actually we should use the SDR PTT/MOX to control the external relay and transmitter via X2-7 as that will insure that the SDR is protected by the proper sequence of changeover. Time for the Universal Control Board. Then all the rigs can be properly selected and sequenced.
