try one of the 12 volt power packs sold in auto parts stores and truck stops. I use one with a 9040 here in the shack sometimes. seems to work ok so far :)

You won't need anything as big as a car battery for the 9040. You could probably go for an hour or two with just 8 or 9 D-cells in series. I saw something the other day about rechargeable 6volt lantern batteries on close-out at wally world. A pair of those in series would be a good size power supply for a 5 watt rig.

Dennis,
a small 7Ah gel cell or like kc2dqv said, get one of the power packs (jumpstart box) from the auto store. It will last all day at 5 watts and as long as you don't let it drop below 10.5 volts you can recharge it over and over or leave it hooked up at home so it is always ready to go. you are on the right track so far. If you run up on one of the 18 Ah cells at hamfests (about $20) they will last days and can be easily charged. Good luck and have fun! I play portable about 60% of my time. I enjoy activating Cabooses, lighthouses, islands and battle grounds. It doesn't take much and you can make it as easy or hard (hiking) as you want.
73 for now,

guys i thank all of you for your input.
now i have sold the mfj..never did like the reciever..couldnt tune spot on..
now i have a ten tec qrp radio 40/20 and a dipoloe.
Randy there are several local towns that have a caboose because they were rr towns in this area. perhaps if i ask nice i can activate a station some time.. yes i'll use ssb for the guys who dont wanna .. but mostly code.. besides, public demos with ssb is a little easier for the general public to figure out..
i could get real lazy although i copy in head fine.. use a screen so folks can see and hear cw.
sounds like more work than using a straight key if ya asked me.
then again as afriend once said. if we had ssb on 10 back in 77 we would a never learned the code enough..to ever go up until 2000 lol

Well Done Dennis,
Glad the rig is working out for you! Yes! The cabooses are a hoot and I'm sure they will let you operate from them. Let us know when and which one you are going to activate. I'll make it a point to work you and maybe from the Burlington Caboose!! LOL
