MY CB GO BOX
« on: September 11, 2017, 02:43:07 PM »
Hello all,
This is my first post and I hope I do not offend anyone but I am a CB'er  :)  Someday eventually I will get licensed and go spend all my extra money on "real" radios but for now CB's suit my needs.  That being said, i do like all the fun Ham's have with their projects.  So I started my own.  A CB go box! Before you all say it, I already have a handheld and a radio in my truck, this is just a fun project and would like to have a base station that i can pack up on a moments notice...I'm kind of a prepper ;) 

I have my radio, speaker, emergency amplifier, swr meter and PA hooked up so far.  I will be installing a second antenna hook up to go to a dipole or eventually a mobile omni-directional antenna (Field Day style)  Photo attached upon approval.

I need some advise for my final components:

1. Battery (thinking a bioenno 30 or 40 amp hour LiFePo4 with a AC smart charger, should give me ample talk time)
2. Rigrunner (I think i have narrowed this down to the RR-4004U-C)
2. Charge controller (for using a solar panel for charging purposes, but not sure if this depends on which panels are used)
3. Battery Meter (I would like to be able to monitor output as well as battery life)
4. Solar Panel (I would like a fold able or roll up solar panel that will travel well, not sure what size i will need)

Once i have these components I plan on Anderson Power Poling all power connections etc. 

I look forward to any feedback!

Hi NF822WNY (wow, that's a mouthful)
Welcome to the forum! 

I don't think anyone here is going to give you a hard time about CB.  Most of have a CB in a box somewhere, just in case the SHTF.  There's probably more CBs out there than ham rigs, so lots of information will be flowing out on 11meters.

I'll ask the standard Radioprepper's question.  How much current does the rig draw in receive?  Batteries are expensive and heavy so I don't go overboard on the size. I figure 12-20hours of listening is a big enough battery.

I'm not much help on your questions.  I just have a little advice on the Charge Controller.  You only need one rated for the amps the solar panel will be putting out, plus some margin.  For power supplies and similar things, I try to buy one that is rated for at least 30% more than I need.  That is, if the radio draws 8A in Tx, I'll probably get a 12A power supply so it's only at 67% max.  As far as brands go, I don't have any advice.

Again, welcome aboard.  That's a fun project you have going there.

Thank you Cockpitbob for your response...  My rig uses about 2A on AM and 4 on SSb...If connected to the amp it draws an additional 10...I figured a 40ah Lifepo4 would let me run about 10 hours stock and close to 3 if full powered.  I think that is a pretty good. 

Thanks for the input on the solar charge controller and panel...at least i have an idea of the size i need to look for. 

I have a pretty good idea that the rig runner RR-4004U-C will work for my power distribution needs, plus its got 2 usb ports that will be handy..

My main question would be on a battery meter...i have read a lot into Ares and Races go box rigs and they have small voltage meters but haven't seen any with a meter that shows voltage and reads the batteries capacity...that would be ideal so i can switch between power levels.

2A and 2A.  I trust that's during Tx, not Rx.  Even so, that's a lot for a 4W CB radio, unless that includes the cough emergency cough amp.  My 100W, all mode, all band ham rig (FT-857) draws about 0.7A during receive.  Receive current is the one I pay attention to since I tend to be listening 90% of the time.

A battery capacity meter would be nice to have.  Much better than just Volts.  I just took a quick look and they exist but I have no idea which ones are good.

Yes those numbers are all via tx not rx...i figure if i plan for tx i will have plenty of capacity.  So 40 ah may be agressive but the capacity will be there if needed, also taking into account if said "amp" were being used.  I dont run a lot of power, id prefer to have a better antenna setup.

Hello and welcome aboard :-)

This site, as much as it may seem like it, is not a ham radio forum, but a radio prepping forum. Of course CBers are welcome, I was one, and CB is a great tool.

I would suggest going as light as practical on the battery and use the amp only in case of extreme necessity. Usually when 11m is closed it doesn't matter how much power you have. For local comms
 it might help, but I'd rather bet on a good antenna, half-wave end-fed, easy since it will be only around 5.5m long!

Thanks Gil!, love your videos by the way!  Thank you for the antenna advise, I have a couple of ideas and will be using this project to further my expedient antenna ideas.  More to post once i get this project into the field.

You're welcome. BTW I highly recommend the Solarcon Imax 2000, great antenna for CB!
