I just wondered if you have ever seen any information about how to tap the I.F of the Tecsun 606 by any chance? I want yo use it for DRM but cannot find any info .
Love the website !
I have not seen info on tapping into the IF of any of the recent Tecsun portables. Can someone help Lee? I would be very curious how to do this myself.
SWling Post reader, Philip Dickinson, recently contacted me with the following question:
“I have just bought a Tecsun 606 which takes two AA batteries which I think are normally rated at 1.2 volts. I have just ordered some lithium ion AA and notice that they are 3.7 volts. Can I use them?”
I replied to Philip that I’m pretty sure I’ve used lithiums in my PL-380 and/or PL-310ET without experiencing any problems. I know I’ve certainly used lithiums in several other receivers. [Update: I’ve always used Energizer and Duracell 1.5 V Lithium AA batteries–not 3.6V AA batteries.]
As I was about to post his question here on the Post, Philip sent another message:
“I found Tecsun’s email address and they rule out the 3.7 volt lithiums. Good job I checked.”
Wow–indeed, I’m glad you checked as well!
I had searched the PL-606 owner’s manual (PDF), but found no reference for voltage tolerances. Now I’m curious if other Tecsun receivers would have difficulty handling the higher lithium voltage.
