Title: HPSDR next Step Post by: WA1GFZ on May 18, 2008, 04:25:27 PM Just got the next HPSDR module working, the Exciter-"Penny"
All mode 160 through 6 meters. Sounds great. At some point it will support EER voice modes. at 1/2 watt nobody came back to me on 3875. Now for some gain.... Title: Re: HPSDR next Step Post by: ka3zlr on May 18, 2008, 06:17:29 PM You got a Picture of this thing Frank..?

This may get you there easier. Right now it is just a motherboard and three plug in boards. They can be mounted in a computer case. I just have mine bolted to a plate with three power supplies. Penny is the reverse of a QSR1 where I/Q go through a digital up converter driving a 122 mHz DAC to make RF. HPSDR will make the RX mate soon so this will be a stand alone All mode XCVR 160 m to 6m. Title: Re: HPSDR next Step Post by: KF1Z on May 18, 2008, 08:40:48 PM Same with QS1R... there'll be an upconverter soon (QS1T)...
Just that we got the RX first.... THEN the TX. Title: Re: HPSDR next Step Post by: WA1GFZ on May 18, 2008, 08:58:52 PM Then it will boil down to who makes the best preselector. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
