Hello All, Rob Ross and I have both received yellow/ orange colored R9012 analog models from the eBay seller "tquchina," which have proven to be substandard in comparison to the black R9012 models from "dpmega." The lemon models have very poor AM performance out of the box (typically receiving only two or three locals), and cannot be aligned up to the sensitivity level of the black R9012's. Further investigation reveals that all the lemon models received so far were made in 2005, and have a serial number of 0892005xxxxxxx. The Tecsun R9012 date of manufacture is actually stamped on the circuit board, below the loopstick mounting position (but usually hidden with tape). In addition, the loopstick coils and coil forms are different in the "good" black models, manufactured in 2008. Tecsun has apparently improved the AM sensitivity in the more recent R9012 models, but the substandard (at least on AM) R9012's from 2005 continue to be sold. For those of you performing an R9012 alignment according to the pictorial just posted on DXer.Ca and the Yahoo groups Ultralightdx and ODXA, please note the date of manufacture stamped on the circuit board below the loopstick position. If your R9012 was manufactured in 2005, you may have a lemon, and may not be able to get frequency coverage from 530-1700 kHz, or bring up sensitivity to a high level. Tecsun R9012 purchasers are requested to check the serial numbers, and report lemon models ASAP. In the interim, please avoid purchasing any R9012 models from the eBay vendor "tquchina." 73, Gary DeBock **************Feeling the pinch at the grocery store? Make meals for Under $10.
