This video shows a simple inexpensive portable battery power supply for the Yaesu FT-857D. This is one more step in the process of making this great radio ready for more remote portable operations.

The battery was purchased at a local HAM swap meet for $8.

Connections are Anderson Powerpole . . . the 12-volt connection of choice.

@USNERDOC - Very nice portable setup. I have two questions for you. How long can your radio run on the 12 Volt 7 amp battery? Is it possible to plug in the coax cable for your antenna into a handheld or must it be used with a base station type radio? My reasons are because I am working on a budget and thinking if I can get a hand held for the car and use a large antenna when I am at home...until I can afford a base station. Thanks in advance.

@leongaines - I will have to do some testing for the run time on the 7a 12v SLAB. Bottom line will depend on percentage of transmit time which uses the most power compared with receive only mode. Yes, you can run the coax to a handheld and use a 12v car battery as a power source . . . something I have done many times.

That is discusting that you can't put up an antenna what happens if there was an emergancy in your area that you need to help with

@2e0hoq - no worries . . . I just throw up one of my portable antennas . . . as we speak, I am listening in and just had a QSO with South America. 73!

hello great set up.like the mobile antenna from base antenna. i tried 2 100 ft telephone extensions end fed. workrd great soaked by 3 days of rain. 857 is a very good radio. i use something similar a icom ic 7000. this class of radio is so full of features. guide cord is very light and very strong. about 3/32" and takes a lot less room.

congrats, keep on having fun. 73 VE6LCK
