Good Morning All,
All materials, including the op-amps, are now in and the first batch
of production v6.0 kits will be mailed today.
I was able to get MAX4489ASA op-amps to use in place of the
unavailable OPA2228UA device in the production v6.0 kit. An example
of the production v6.0 kit has been built with the Maxim op-amps and
the receiver plays properly with very good phase and gain correction
by Rocky over the 96 kHz tuning range. The MAX4489ASA has a noise
spec of less than 5 nV / rt.Hz at above 1 kHz and has a Gain-BW
product of 42 MHz.
The latest project documentation has been uploaded to the SoftRock
v6.0 docs folder. Missing from the folder is the builder's notes
file that I still need to convert to .pdf format.
Please let me know if you find errors or problems with the project
Thanks and 73,
