[R-390] Synchronous AM Detector Kit

[ToddRoberts2001@aol.com]

In case anyone is interested, Steve Johnston WD8DAS is again offering his AM 
Sync Detector kit for $159 or assembled for $229. His prices include shipping. 
His sync detector uses the famous Sony AM Stereo IC - the same one used in 
the Sherwood unit I believe.  The IF center freq is 455 KHz but is adjustable 
for IF's of 400-500 KHz so it could be used with other receivers like the 
R-388/51J-4 with 500 KHz IF. Should work great with the R-390A. The audio output is 
around 100mv suitable for connecting to an external audio amp. I am ordering 
one and will be glad to report to the list how it works. You can read more 
about it at this address :   <A HREF="http://www.qsl.net/wd8das/syncinfo.txt">http://www.qsl.net/wd8das/syncinfo.txt</A>           73
