Tired of changing batteries, even "only once a day with NiMH's", disregarding the advice of elders, >>>>> "Bob" == Bob Parnass, AJ9S writes: Bob> You will probably destroy the IC-R2 if you connect an AC transformer Bob> to the DC battery contacts. DO NOT do it. young Dan (a/k/a me) proceeded to... <ZAP>... well the radio is OK still, but my conclusion is: one cannot fool the R2. It can tell real batteries from any fake baby pacifier you try to give it. Sorry, I didn't give it 120 V AC, as _I_ am college educated. I did try a "1.5 VDC 300mA" "wall wart" that gave the same 2.2 VDC reading on my tinseltown multimeter as does a pair of NiMH. I recall beeps even before hitting the "on" button... and then refusal to turn on. Not enough juice? OK, then: I also tried "3 VDC 800mA" from a "automobile cigarette lighter wart". More beeps and flashing of LCD... never with real batteries does one see anything before hitting the on button. With my 'alternate power source' it thinks I never turned it off or something. All in all harrowing experiences. The R2 is no simple light bulb apparently. It can tell real batteries from non-batteries. And supposing one does come up with something that resembles a battery to the R2, one must still weld or use alligator clips, etc. I've got fist sized 6VDC gel batteries as found in emergency lamps. Do I just add one resistor to make this a 3 V power source for the R2? How about a 12V car battery? Question 11 (35 points): The Martians have attacked, stealing the world's supply of AA batteries, and kidnapping the battery bunny. Your mission is to monitor Martian communications and rescue the bunny in time for Easter. However, all you have is a 12V car battery. What circuit do you rig up to power the R2? P.S. I'm reading and posting this on gmane.recreation.radio.hardware.icomr2 of http://gmane.org in far away Norway.
