[R-390] Sync Det III

[Perry Sandeen]

List,  
 
The hunt continues! 
 
I had to reformat this message removing most of the
prices as the reflector list spam filter rejected it as looking like spam.
 
 
Thanks to a tip from Sam Letzring and others I
learned that the needed IC’s are sort of available with the SA prefix.
 
One problem will be that most of the parts
supplies carry the SOIC versions but I found a few exceptions. 
 
What I found:
 
Newark:  They can get the IC’s from England but they are pricy.  Newark also carries a SOIC 16 to DIP 16 ARIES
- 16-350000-11-RC - IC ADAPTER, 16-SOIC TO 16-DIP.  The prices are much larger than DigiKey and
Mouser.
 
Mouser:  Mouser
Part #: 771-SA602AN/01 Description: RF Mixer LP VHF DBL-BAL W/OSC 
Mouser Part #: 771-SA604AD01112 Manufacturer Part
#: SA604AD/01,112       
 
Digikey:
 
68-1202-5-ND.           SA604AD/01,112
NXP Semiconductors IC FM IF SYSTEM LOW PWR 16-SOIC   
 
68-1200-1-ND            SA602AD/01,118
NXP Semiconductors IC MIXER 500MHZ UP CONVRT 8-SOIC       
 
Ebay Stores hifiic:
 
SA604N 16 pin DIP High performance low power FM IF
system 
 
Heinz Breuer found these two DIP parts:
 
221134875281 PHILIPS NE602AN DOUBLEBALANCED MIXER
AND OSCILLATOR 
 
320995189811 SIGNETIC / PHI DIP,Single Radio
Communication IF Amplifier, NE604AN 
 
I’m going to search some more based on Todd
finding some for $42/100
 
I’m in the process of redrawing the original
schematic with photoshop elements into a bit image that can be reproduced in
any size W/O smearing.  I’ll make a
posting on the list when I’m finished and will email it to any interested.
 
A bit further down the track I’d like to get a PC
board made using through hole components.  I have nothing against the new stuff but it is so small that it is too
hard for me to use.
