POST BY RAHUL VU3WJM ON THE BITX SDR





Hi! All

Once we had a very interesting discussion on the group for a BITX SDR design.

Whie visiting the local mkt I came across some xtals of very intersting frequencies 16.xxxMhz and

18.432Mhz standard clock freq.

16.xx Mhz can generate some very nice 90deg phase shifted LO's at 4.xx IF freq similar to one used in

K2.

The idea of line up is like to use BITX RF/TX preamps,doubly balanced diode RX/TX mixers. BITX post

mixers , 4.xx mhz BPF, 74hc series BITX S/H detectors with the 16.xx xtals generation the 90 deg clock,

NE5532 baseband ampifiers.

18.432Mhz can be used as LO in super VXO config for abt 100KHz coverage on 20 mtrs else optional input

can be provided for an Si570 multi band VFO setup.

Just require your valuable inputs before I proceed with the new design ....Ver5????

Hi Sunil, I was wondering if it could be taken into consideration with the development of the software for the up and coming BITX SDR if something like Quisk or similar software that is available for both Linux & Windows.

I am always looking at SDR projects and I see that more and more are looking at Linux & Windows. There is some great Linux software out there for this task.

Regards
