Funny you should ask............................I am working on a new
iteration for the MW receiver. The 2nd I.F. subsystem will be using an
NJM2552 AM/FM chip. Using this device, I will be able to take the limited
I.F. signal out of the FM section and send it straight to the Sync detector.
I am waiting for samples on this device.
SI has put the project on the back burner for the time being...........they
still have to get the control code together for the display.
The Drake '4-line synthesizer has a bug in the control
code........incrementing up in frequency is fine, but when you tune down the
rules sometimes go out the window. I have tested the prototype on my SPR-4,
and it does work very well.

Maybe I've missed something, but it seems to have been a while since I
last read anything on Pete G.'s MW receiver. The website for Silicon
Engines says nothing about it and I am wondering if the project ended
up going to another company along with him.

BTW, if Pete's reading this, have you done anything with your design
for a frequency synthesizer for the Drake R4 line?
