Re: [TenTec] 229A SWR Circuit - UPDATE (score: 1): Author: Rick W <ve7tk@yahoo.ca>; Date: Sun, 1 Jul 2012 09:44:43 -0700 (PDT); I hung my DVM off the 200uA meter plug and it is completely within specs. Fully adjustable and it seems to be working. So it looks like the Korean made 229A meter has failed. I'll have to do some t; /archives//html/TenTec/2012-07/msg00006.html (8,813 bytes)

If they ever failed and were replaced with silicon diodes, that can mess up calibration badly.

The original diodes are 1N4148 as indicated on the schematic. Since these were so plentiful in my spares I replaced the pair of diodes in the 229A circuit before my; /archives//html/TenTec/2012-07/msg00010.html (11,734 bytes)

You might check with Ten Tec about a repla; /archives//html/TenTec/2012-07/msg00022.html (7,880 bytes)

Not sure what the basic movement is without the shunt. -Lee WA3FIY _________________________________________; /archives//html/TenTec/2012-07/msg00029.html (8,628 bytes)

There is no shunt. I suggest you check with Paul at Tentec Service to obtain a replacement. Plus, it wil have the correct scale.
