Tecsun PL-606: Tapping into the IF?

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.

Tecsun cautions against using Lithium AA cells in the PL-606

TecsunPL-606

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.

Please comment if you have insight!
