I am building a tactical setup to cover everything. For 70cm/2m I have a new Yaesu FT7900R. http://www.universal-radio.com/catalog/fm_txvrs/0790.html

For the rest I have a TenTec 555 Scout. http://rigreference.com/rig/4184-Ten_Tec_Scout_555

I even have a TenTec 1208 6M transverter. http://rigreference.com/rig/4054-Standard_C_1208

For power I have a Samlex SEC 1235M. http://www.universal-radio.com/catalog/hamps/1235.html

For tuning I have an MFJ 945D. I will get a better one.

I want a rig that I have to fumble with as little as possible. I want to have one plug that if I find a power source I can plug it in and when I have to leave, just unplug and walk away with the radios ready to go. Otherwise, I will have a hand crank generator and two roll-up solar panels. http://www.solarblvd.com/Solar-Panels-&-Systems-Individual-Solar-Panels-3---19-Watt-(9)/c1_25_39/p1874/Iowa-Thin-Film-PowerFilm-9-Watt-12-Volt/product_info.html

I want a lot of battery and don't mind extra weight. I will budget twenty pounds for battery storage.

I will have a Buddipole to go with it. http://www.buddipole.com/debupa.html

I would also like to mount a cooling fan and maybe two small LEDs.

First, do I have too much power supply with the Samlex? Next, what batteries do I need? Finally, am I missing anything? I know very little about this and I am trying to learn.

There is a good article in the September issue of QST magazine. It does a great job of covering battery types, chargers, power supplies, etc. If you are an ARRL member you can access it here, http://www.nxtbook.com/nxtbooks/arrl/qst_201209/index.php#/38.

You're not going to get a lot of battery capacity for 10 pounds. A 12V 18 Ah sealed lead acid battery weighs about 12 pounds. How long it lasts is highly usage dependent. Without doing the math, you're probably talking about hours not days.

The 35A Samlex power supply is overkill for your setup but if you've already got it, use it. The extra current capacity won't hurt anything. Be sure to fuse your connections properly however.

I don't think you'll find a hand crank charger useful. The amount of energy you can extract from a human is pretty low. Invest the money in more solar panels.

Gotcha. I am pretty stout and I can do 20 pounds fine. I am packing the radios into a frame inside a Kelty backpack.

As for the hand crank, I get that, I'm just trying to have as much as possible. Do you think I could make enough for ssb or cw?

Also, I'm waiting for this pedal generator to finally hit the market: http://www.k-tor.com/pedal-powered-generator/

I've got several of these that you can have for the price of shipping if you want them....

They are sold out last time I checked. I really wanted one for my tj4a


Op, your best bet is (you don't want to hear it) is just get an 857.
