How about adding the X2 connector on the SDR1500. The X2 connector works well on the SDR1000 for many VHF / UHF hams. It is an easy and realiable way of controlling transverters and other external devices. Maybe other VHF/UHF operators can provide some input on this.

I don't think anyone has anything that is a Flexwire peripheral yet.. PowerSDR doesn't have any sort of real way to talk to it yet (aside from modifying the source code) in the vein of some sort of configuration screen. Since FlexWire is basically I2C, I'm not sure how well it would work for something where you needed reliable deterministic timing on a millisecond time scale (if you were planning on timing your PIN diode switch to protect your GaAsFET preamp). I've implemented things with precision using I2C before, but it typically requires a fairly low level software driver. If the interface is exposed through multiple layers of a protocol stack, it might be tricky. OTOH, I would also say that critical timing shouldn't be done in application code running on a PC anyway, so maybe it's not an issue. _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kb.flex-radio.com/ Homepage: http://www.flex-radio.com/
