OM VU3WJM Rahul has confirmed that he is working on the project, we shall be updating the news for the project as we get any new info from OM Rahul
We are posting the details of the post Rahul made regarding the BITX SDR in the Yahoo Bitx forum
POST BY RAHUL VU3WJM ON THE BITX SDR
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
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????
