My "solar generator" is homemade.

I am using a four pack of LiFePO4 20AHr batteries.  -


A 2 Amp MPPT Charge controller from diysolarforu -- see: for current models (mine is out of stock)

Mounted (with room to spare) in a plastic "ammo" case. -- this size would work:

I am using a 25 Watt solar panel. --   -- The "p3" charge controller will handle 60 Watts.  Use a larger panel.

ALL of my electrical connections use Anderson Power Pole(s).
I use yellow/black for the solar panel.
I use red/black for 12V out.

The charge controller provides a battery voltage readout (as does the radio).  I use a monitor on a 60AHr battery system.  --
BTW, the 60AHr "pack" uses a different BMS "system" and a 25 Amp DC to DC (plus solar) charge controller and with two hours of driving, I can fully re-charge the battery from the vehicle (see:


I ran a Elecraft KX3/KXPA100 (see: *1) at 70 watts into a 1:1 + 9:1 homemade balun with a 12m mast (see: *2) and 12m of wire and an (aprox)20' counterpoise that I use a Coghlan's Camp Laundry Reel for my counterpoise wire (teflon)(see *3).
A 4B + 4G RAM - Raspberry Pi (Headless) ran Fldigi with a USB sound card (see: *4) and Elecraft USB CAT control.  I ran "remote" with VNC from a cooler(?) kitchen table.
BTW, I use a West Mountain RIGrunner for fuses and a fan to keep the Amp cool.

I hope the links save someone time, IF they want to look up what I am "going on" about.

Steve, which “solar generator” did you use, and what equipment did you run with it?

Modified the way the counterpoise is used for the 12m vertical. 
At 1900z... 20m, FT8 @ 9 watts SO, PSK31 @ 70 watts should work?.
I "just" need people listening.


I did make some QSO's.
At 2200z and then some... I packed up the Rig, Computer, and Solar Power "generator" from the deck to have dinner (I am not leaving the rig out on the deck for all to see as they drive/walk by - we live on a corner, so no "backyard".)

OK, I did get on and make a few QSO last night.  Later then I expected as company dropped by.

NOW, today (after 1200z)  I had problems getting the "working last night" W10 machine and Winwabler to work (correctly - as it was last night).  Is it the heat (87F going to 92F) ??  maybe?  

I switched to my Raspberry Pi + Fldigi.  It is working, but I am seeing only PSK63 and stations working EU PSK contest.

IT IS hot, I am going to try later this afternoon.  I was only running 5 Watts, but solar...  The 12m mast with 12m wire/9:1 balun tunes well.  I tested 80m to 15m with good SWR before using the ATU.

CHANGE - tonight 0000z to 0200z I will NOT be portable...  BUT I will be on 80m from DE for anyone needing the state.  IF, 80m is a dud, I will move to 40m...  I will be running 70 watts.  I will also "chase".

I am trying to "iron" out the kinks with Winwabler.  I have used it before, its been a while.  Not using Raspberry Pi as I "think" Winwabler (and W10) may be better for "contests" aka FD. 

Tomorrow, morning (after 1200z) I plan on being portable.

OK, since May 22 starts at 00z... 
Weather permitting (forecast - to be nice)  I will be on 80m (maybe 40m) from 00z to 02z. 
I "expect" to be running 70 watts.

Weather permitting, I plan on being active May 22.  "portable" from the backyard deck. 
I will at least be running 10 watts.  Antenna 12m random wire vertical. 
Current forecast is cloudy and <25% chance of rain, but 86F may limit me to morning hours.
A nice "dry" run for Field Day...

Plan 20m and 40m

changes will be announced via email.
OK, if the station is outside with portable antenna, can I operate remote?  (inside - not in shack - portable wifi)

CHIMP CHASE  -  Let Us Know Your Plans


You’ve had a couple weeks to make your plans. Please let us know if you plan to go Chimp Chase portable and we will look for you!!


A Chimp qualified portable expedition site must be away from your home radio shack. You may use home power but you need to set up a temporary/portable antenna and station away from the home shack. Backyard ops and park picnic benches are encouraged for this category.
