![]() I consider buying a waterproof handheld VHF to be used as some sort of reserve radio in case mast and antenna are lost, fixed VHF fails or need to abandon the boat... What about radios that use AA cells instead of rechargable battery pack? As far as I understand, rechargable batteries need to be charged every now and then even if the radio is not used. And alkaline AA cells, though have lower capacity, do not decay. I plan to leave the radio in my grab pack, and would not like to worry about charging NiCd pack every month... Any suggestions for a good handheld? What about Icom M-31 ? Or some similar reasonably priced set? Mika |

In each price range, you will probably notice that each radio offers the
same features. If you buy one that uses rechargeable batteries, there's an advantage to it if it can also run on several AA batteries. My radio came with a NiCad Battery pack that fits in a holder. The Battery pack can be removed from the holder and replaced by AAs. I also bought a spare rechargeable NiCad battery pack. The one disadvantage of my radio is that the battery pack needs to be in the battery while being recharged, and isn't to be operated while charging. So, if a battery pack runs down while I'm out, I can replace it, but I can't recharge it and use it at the same time. "Mika the Spamkiller" wrote in message ...

Oh, that rechargeable advertising is really effective.....(c; If you're going to use this only for an emergency radio, I highly recommend using Alkaline AA cells instead of a rechargeable battery pack (which will kill itself in 3 months). What they don't tell you is a good, brand-name alkaline battery has 4-8 TIMES the AH capacity of the finest rechargeable. For instance, an Alkaline D cell for the flashlight is now around 15 AH! They've gotten much better. AA cells are around 5AH, now. Shelf life on an alkaline cell is 5 years, so change them out and use the old ones every couple of years. DO NOT LEAVE THE BATTERIES IN THE RADIO! Radios only switch the lower-powered parts of the receiver, NOT the big transmitter IC that provides the RF power output. So, there is always a tiny drain current you're not supposed to notice leaking away all the time. A marine walkie will kill its rechargeable in a month of not being charged by it. Put the alkalines already in their battery holder pack in a ziplock storage bag attached to the radio for emergency use. That will keep them dry and reduce leakage caused by salt corrosion in the boat. Just put them all in the grab bag, but not plugged into the radio and they'll be ready when you are....Test the radio every 6 months to make sure it's still working. I have 4 Icom ham radio walkies with perfectly good batteries that were stored in a closet. ALL FOUR of them failed just sitting in the air conditioned house whos temperature never varies more than 2 degrees from 70F. Crazy, eh? -- Larry |

: Any suggestions for a good handheld? Someone gave me a Standard H-262 walkie they'd left in a lazarette and forgotten about. The screws are rusted and it was awful looking. The battery pack was toast, so I took it apart and hauled the cells up to Batteries Plus store here and had the nice boy build me a new pack using 2,500 mAH Ni-metal hydride cells, instead of the cheapassed Ni-Cd crap all the OEMs use in their $120 battery packs. The abused Standard fired right up and is now my favorite marine HT! It's much better than my Garmin 725, easier to operate. Already "rust tested", I cleaned off the bilge crud and replaced the rusty screws. It takes almost 2 days to fully charge these monster hydride cells from the little trickle charger, then you can operate the thing all weekend, 24/7 in normal use and never hear it start beeping about dead batteries. I'm very impressed with these Standard/Vertex walkies. Of course, they ARE Yaesu- made...my favorite ham equipment...so I'm a little prejudiced...(c; -- Larry |

Any suggestions for a good handheld? What about Icom M-31 ? Or some similar reasonably priced set? I used to be an ICOM partisan, but Standard has converted me. My HX350s came with a built in rechargeable battery, an AC charger, a DC charger, and a standard AA battery back as well. It's a good little radio and I love the separate squelch knob. I think the HX370s is the current version. It deletes the squelch knob but adds a strobe, I think. It's probably not a great strobe, but it does sound as if it would go well in a ditch bag. They go for about $150 on ebay, I think. For your specified use, stay away from rechargeables. If you want rechargeables, you still want a standard aa battery pack so you can toss in (relatively) inexpensive NiMH AAs instead of buying proprietary battery packs. Rechargeables can't be beat for price/performance in regularly used equipment, but the self-discharge rate is unacceptable for emergency gear. __________________________________________________ __________ Glen "Wiley" Wilson usenet1 SPAMNIX at world wide wiley dot com To reply, lose the capitals and do the obvious.

You don't want "waterproof", you want "submersible".
"Waterproof" means "kinda sorta splashproof and we'll replace it on warantee if it gets wet". "Submersible" means "3 feet, 30 minutes." And what Larry says about the AA alkalines is right on.

the Icom units are great.
