The C6050G IC is an MC 1496. I used it myself for a product detector way back in the late 70's. I was going to make a little direct conversion receiver with it but never finished the project. Later, when I got my R4C I put the TL 442 based product detector in it and in an R4B. They worked great and the one in the R4B is still there. I completely redid the R4C with all new Sherwood mods about 5 years ago. It's still a great receiver. Steve KD2ED In a message dated 3/11/2012 7:53:10 P.M.

Sounds like an early mod. I've seen them and mods to the C-Line were quite common back in the late '70s and early '80's. I'm thinking that it's actually harder to find an R-4C that doesn't have any changes. The folks who bought Drakes were generally more willing to go inside and soup them up. 73, Steve Wedge, W1ES/4 Live free or die: Death is not the worst of evils. John Stark.

I removed it to make way for the new PD-4, but am curious is this could be one of the early Sherwood ones or maybe a Santori version. It is on a small perf board and uses a Motorola HEP C6050G IC. I don’t have any of the HR magazines that described the DIY mods, maybe it’s time to get the CDs. I’m just wondering what it is...I’ve had this set since 1995 and have only installed the Inrad GUF-1 up to now. I've also done the LED lamp kits and they look great. For those who maybe considering doing any mods, be aware that wayward soldering irons love s-meter pots. For the folks who despise any Mods, sorry for the offense. Thanks for any info. 73, Robb N0RU Woodland Park, CO ____________________________________ _______________________________________________ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist _______________________________________________ Drakelist mailing list Drakelist@zerobeat.net http://mailman.zerobeat.net/mailman/listinfo/drakelist
